Patterns and processes of cladogenesis among taxa living on the Mozambique ‘sky islands’ remain poorly studied. During the present study, we report on a new freshwater crab species from Mount Lico, an inselberg and ‘sky island’ in the Zambezia Province of Mozambique. Phylogenetic analyses using three mitochondrial DNA sequence loci (12S rRNA, 16S rRNA and COI) were used to determine the evolutionary placement of the freshwater crab specimens from Mount Lico. The freshwater crab specimens from Mount Lico were retrieved sister to Potamonautes choloensis. The new species, Potamonautes licoensis sp. nov., is described and compared with other southern African freshwater crab species. Divergence time estimations for the Mozambican freshwater crab species suggest a Miocene / Plio–Pleistocene diversifi cation. Some endemic ‘sky island’ species form an early branching and are sister to other predominantly East African species, while other ‘sky island’ species are more recently derived and nested within a predominantly southern African clade. The present study presents the description of the fourth endemic freshwater crab species from Mozambique and suggests that the species diversity in the country is likely highly underrepresented, reiterating the call for renewed systematic surveys. An argument for the conservation of these mountainous ‘sky islands’ is presented.
On eight species of the spider genus Synagelides Strand, 1906 from China (Araneae: Salticidae)
(2020)
Six new species of Synagelides Strand, 1906 are diagnosed and described: S. bohdanowiczi sp. nov. (♂♀), S. leigongensis sp. nov. (♂♀), S. logunovi sp. nov. (♂♀), S. subgambosus sp. nov. (♂♀), S. wuliangensis sp. nov. (♂♀) and S. xingdouensis sp. nov. (♂♀). The female of S. forkiforma Yang, Zhu & Song, 2007 and the male of S. longus Song & Chai, 1992 are described for the first time. Photos of the habitus and copulatory organs, as well as a distributional map, are provided.

The genus Plagigeyeria Tomlin, 1930 is one of the most typical elements representing the stygobiont fauna in the southern Dinaric Alps. In the current study I present the territory of Hercegovina (and its adjacent regions of Bjelašnica and the Dalmatian coast containing transboundary aquifers) as one of the two main biodiversity hotspots for distribution of the genus. It is comparable with the species radiation of Plagigeyeria in the Kotor Bay–Skadar Lake Basin area. My study of the karst springs and caves revealed, besides the presently known species, twelve new Plagigeyeria taxa detected in so-far uninvestigated karstic aquifers: Plagigeyeria erossi sp. nov., P. ljutaensis sp. nov., P. konjicensis sp. nov., P. pseudocostellina sp. nov., P. reischuetzorum sp. nov., P. olsavskyi sp. nov., P. listicaensis sp. nov., P. ozimeci sp. nov., P. jakabi sp. nov., P. angyaldorkae sp. nov., P. vriosticaensis sp. nov. and P. lewarnei sp. nov. Closer shell morphology investigation supported by the protoconch morphology revealed a presence of another genus within the former Plagigeyeria complex. The following taxa are transferred herein to Travunijana Glöer & Grego, 2019: Plagigeyeria robusta Schütt, 1959, P. robusta asculpta Schütt, 1972, P. ovalis Kuščer, 1933, P. edlaueri Schütt, 1961, P. klemmi Schütt, 1961, P. nitida Schütt, 1963, P. angelovi Schütt, 1972 and P. tribunicae Schütt, 1963, plus a new species, Travunijana gloeri sp. nov., is described for the genus. Distribution maps of both genera, Plagigeyeria and Travunijana, over the karst aquifers of Hercegovina and adjacent regions are presented with respect to the hydrogeological separation of the known spring karst conduits and aquifers.
We describe three new parastenocaridid: Cottarellicaris sanctiangeli Bruno & Cottarelli sp. nov., Stammericaris vincentimariae Bruno & Cottarelli sp. nov. and Proserpinicars specincola Bruno & Cottarelli sp. nov., collected in the pools of five different caves located in Calabria (Southern Italy). We conducted a phylogenetic analysis based on the mitochondrial COI and ribosomal 18S sequences of C. sanctiangeli sp. nov. and S. vincentimariae sp. nov., and of four more species of Stammericaris and one Proserpinicaris available from literature. Based on the molecular study, the specimens of C. sanctiangeli sp. nov. are clearly separated from the species belonging to the closely-related genus Stammericaris. The morphological and molecular data indicate that the genera belonging to the two subfamilies Parastenocaridinae and Fontinalicaridinae form two monophyletic and distinct clades, thus supporting their status. We also provide insights on the genus Proserpinicaris based on morphological data only; in particular, the most important synapomorphic character of the genus, i.e., the taxonomic value of the hyaline structure inserted on the anterior surface of the male leg 4 basis, is discussed based on the development of the P4 endopod, as observed in the last copepodid stage of some species of this genus. Finally, we widen the biogeographic and ecological knowledge of the three genera.
The geographical range of the typically host-specific species of chewing lice (Phthiraptera) is often assumed to be similar to that of their hosts. We tested this assumption by reviewing the published records of twelve species of chewing lice parasitizing wild and domestic chicken, one of few bird species that occurs globally. We found that of the twelve species reviewed, eight appear to occur throughout the range of the host. This includes all the species considered to be native to wild chicken, except Oxylipeurus dentatus (Sugimoto, 1934). This species has only been reported from the native range of wild chicken in Southeast Asia and from parts of Central America and the Caribbean, where the host is introduced. Potentially, this discontinuous distribution is due to a low tolerance for dry environments, possibly exacerbated by competitive exclusion by Cuclotogaster heterographus (Nitzsch, 1866). Our examinations of O. dentatus also revealed that this species differs significantly from other species of Oxylipeurus in the male and female genitalia, head structure and chaetotaxy, and other morphological characters. We therefore here erect the monotypic genus Gallancyra gen. nov. for O. dentatus, and redescribe the type species.
Species of the genus Coelostoma Brullé, 1935 belonging to the subgenera Coelostoma s. str. and Holocoelostoma Mouchamps, 1958 from the Indian subcontinent are revised. Six species of Coelostoma s. str. and two species of Holocoelostoma are recognized, of which two are described as new: C. (Coelostoma) lyratum sp. nov. (India: Maharashtra) and C. (Coelostoma) nostocinum sp. nov. (India: Maharashtra, Goa, Karnataka, Kerala). Coelostoma (Coelostoma) fallaciosum Orchymont, 1936 and C. (Coelostoma) vividum Orchymont, 1936 were recorded for the first time from India and Bangladesh, respectively. Lectotypes are designated for C. aeneolum Régimbart, 1903 and Hydrobius stultus Walker, 1858. The previously confusing situation with Coelostoma (Holocoelostoma) stultum (Walker, 1858) and C. (Holocoelostoma) bhutanicum Jayaswal, 1972 is clarified based on new material of both species from India. Coelostoma sulcatum Pu, 1963 from China is removed from the synonymy of C. stultum and considered as a likely synonym of C. bhutanicum, a status which needs to be confirmed by a detailed study of type specimens. All species are (re)described and illustrated. Diagnosis of the subgenera of Coelostoma are modified in order to accommodate the species of the Indian subcontinent, resulting in narrowing down the concept of Coelostoma s. str. and widening the concept of Lachnocoelostoma Mouchamps, 1958.
We describe a new species of the genus Zhangixalus Li, Jiang, Ren & Jiang, 2019 from Ha Giang Province, Vietnam based on morphological and molecular data. In the molecular phylogenetic analyses, the new species is nested in the Zhangixalus duboisi (Ohler, Marquis, Swan & Grosjean, 2000) group, where it is sister to Z. duboisi with a genetic distance of 2.51%. The new species, Zhangixalus franki sp. nov., differs from its congeners by a combination of the following morphological characters: size large, SVL 77.9–85.8 mm in males; finger webbing formula I1-1II0-1III½-0IV; dorsal surface of head and body green with dark brown spots; ventral surface grey or dark grey, white stripe along edge of jaw, insertion of limbs, and along lateral ridges of fore and hind limbs and flank, separating upper green part from lower grey part. The new species occurs in evergreen montane tropical forests at an elevation of ca 1300 m a.s.l. The new discovery brings the total number of known species in the genus Zhangixalus to 38 and the species number reported from Vietnam to nine.
Two new species of Grandidierella Coutière, 1904 from Singapore waters are described based on specimens collected during the Comprehensive Marine Biodiversity Survey (CMBS) between 2010–2015. Grandidierella pawaiensis sp. nov. differs from the rest in the genus by a combination of characters; (1) gnathopod 1 carpus proximoventral corner with apically acute process, (2) inner face of carpus of gnathopod 1 proximoventral corner with curved process, (3) proximal margin of dactylus of gnathopod 1 male with excavation, and (4) gnathopod 2 basis anterior margin crenulate. Grandidierella sungeicina sp. nov. on the other hand, is distinguishable from other related species of Grandidierella found in the tropical region by its paired mid-dorsal projections on pereonites 2 to 5, 1 ventrodistal triangular projection on pereonite 4, and gnathopod 2 ischium with 1 large trapezoid projection.
The chewing louse species Lipeurus megalops Piaget, 1880, is redescribed and illustrated. This species has previously been placed in the genus Oxylipeurus Mjöberg, 1910, but marked differences in preantennal structure, male and female genitalia, abdominal chaetotaxy, and structure of abdominal plates indicate that this species is not closely related to other species in this genus. We therefore erect a new genus, Calidolipeurus gen. nov. for this species. Calidolipeurus is presently monotypic, containing only Calidolipeurus megalops gen. et comb. nov. We also provide a preliminary key to the Oxylipeurus-complex.
The first Oriental species of the genus Trichopsomyia Williston, 1888, Trichopsomyia pilosa sp. nov. (Java), has been discovered and is now described. This Oriental species of Trichopsomyia has several characters strongly differing from the other species within this genus. It is hypothesized that it forms a separate group within Trichopsomyia. One species, Trichopsomyia formiciphila Downes, Skevington & Thompson, 2017, from Australia, is similar to the Oriental species described here, and the group is named after this first described species, hence the formiciphila group. The characters for a future phylogenetic analysis are discussed. The character states of the pilosity of the katepisternum and the shape of the metasternum hitherto used in a phylogenetic analysis of Syrphidae Latreille, 1802 are discussed too.
In the ancillariid genus Amalda, the shell is character rich and 96 described species are currently treated as valid. Based on shell morphology, several subspecies have been recognized within Amalda hilgendorfi, with a combined range extending at depths of 150–750 m from Japan to the South-West Pacific. A molecular analysis of 78 specimens from throughout this range shows both a weak geographical structuring and evidence of gene flow at the regional scale. We conclude that recognition of subspecies (richeri Kilburn & Bouchet, 1988, herlaari van Pel, 1989, and vezzaroi Cossignani, 2015) within A. hilgendorfi is not justified. By contrast, hilgendorfi-like specimens from the Mozambique Channel and New Caledonia are molecularly segregated, and so are here described as new, as Amalda miriky sp. nov. and A. cacao sp. nov., respectively. The New Caledonia Amalda montrouzieri complex is shown to include at least three molecularly separable species, including A. allaryi and A. alabaster sp. nov. Molecular data also confirm the validity of the New Caledonia endemics Amalda aureomarginata, A. fuscolingua, A. bellonarum, and A. coriolis. The existence of narrow range endemics suggests that the species limits of Amalda with broad distributions, extending, e.g., from Japan to Taiwan (A. hinomotoensis) or even Indonesia, the Strait of Malacca, Vietnam and the China Sea (A. mamillata) should be taken with caution.
Fourteen species of Chalcidoidea (Encyrtidae, Eulophidae, Eupelmidae, Eurytomidae, Pteromalidae and Torymidae) were obtained from the common reed, Phragmites australis (Cav.) Trin. ex Steud. (Poaceae) in the Urmia region, in the northwest of Iran. Among these species, two new species of Pteromalidae are described hereafter: Norbanus persicus Lotfalizadeh & Rasplus sp. nov. and Stenomalina delvarei Lotfalizadeh & Rasplus sp. nov. Anagyrus near alienus Japoshvili, 2002, Asitus sp., Cheiloneurus paralia (Walker, 1837), Echthroplexiella obscura (Hoffer, 1952), Neococcidencyrtus poutiersi (Mercet, 1922) (all Encyrtidae), Aprostocetus orithyia (Walker, 1839) (Eulophidae), Eupelmus phragmitis Erdös, 1955 (Eupelmidae), Aximopsis deserticola (Zerova, 2004) comb. nov., Tetramesa phragmitis (Erdös, 1952) and Tetramesa sp. (all Eurytomidae), Homoporus febriculosus (Girault, 1917) (Pteromalidae) and Torymus arundinis (Walker, 1833) (Torymidae) were also obtained from our laboratory rearing. Nine of these species are recorded for the first time from Iran.
Three new Neotropical species and a new genus of land flftworms (Platyhelminthes, Geoplaninae)
(2020)
Three new Neotropical land planarians (Platyhelminthes, Tricladida, Geoplaninae) from the Brazilian Atlantic forest are described. Obama apiguara Oliveira, Almeida & Carbayo sp. nov. presents glandular fossae opening through dorsal epithelium, a structure not documented previously among land flatworms. Paraba tata Bolonhezi, Lago-Barcia & Carbayo sp. nov., is characterized by a prostatic vesicle horizontal with an inconspicuous bifurcate portion, a penis papilla as long as male atrium and a female genital duct projected from the postero-dorsal section of the female atrium. The third new species is distinctive in the extraordinarily thick muscle surrounding the prostatic vesicle, a finger-shaped penis papilla, and a dilated female genital cavity. These attributes stands the species apart from all members of Geoplaninae and Piima ata Carbayo gen. et sp. nov. is proposed.
Two new species of Kaempferia L. (Zingiberaceae), Kaempferia nemoralis Insis. sp. nov. and Kaempferia pascuorum Insis. sp. nov., from Cambodia and Lao PDR are described and illustrated. Morphological similarities to their closely related taxa are discussed. Kaempferia nemoralis Insis. sp. nov. is compared with Kaempferia larsenii Sirirugsa in its vegetative parts, but distinguished by the following characters: whole plant taller, leaf sheath and young shoot apex green, petiole absent. It differs from Kaempferia rotunda L. in its floral parts by the following characters: presence of peduncle, floral tube longer, labellum purple with white line at centre, anther crest obovate, bifid, apex irregularly rounded and ovary glabrous. Kaempferia pascuorum Insis. sp. nov. is compared with Kaempferia larsenii Sirirugsa. Proposed IUCN conservation assessments are also given: Kaempferia nemoralis Insis. sp. nov. occurs in disturbed, open forest and is assessed as CR, whereas Kaempferia pascuorum Insis. sp. nov. occurs in short grassland and is assessed as EN.
The current knowledge of the scorpionfly genus Dicerapanorpa Zhong & Hua, 2013 is taxonomically reviewed. Two new species of Dicerapanorpa are described and illustrated, increasing the species number of this genus to 20. Dicerapanorpa bifurcata sp. nov. from the Minshan Mountains, Sichuan Province, is characterized by the absence of the paramere basal branch and the elongated mesal branch in males, and the medigynium having a short basal stalk in females. Dicerapanorpa zhengkuni sp. nov. from the Wuling and Miaoling Mountains, Guizhou Province, is distinguishable by the greatly elongated hypovalves, the very short basal branch of the paramere, and the dorsomedially curved lateral branch in males, and the rounded main plate of the medigynium in females. An updated key to species of Dicerapanorpa is presented.
The diversity of Porifera from Ponta do Ouro (Mozambique) has been evaluated; this paper presents the first taxonomic effort devoted to sponges in the area, while studies of closeby areas are quite dated. Overall, 55 specimens were examined, leading to 26 described species; among these, four are new (Hyattella sulfurea Calcinai & Belfiore sp. nov., H. pedunculata Calcinai & Belfiore sp. nov., Amphimedon palmata Calcinai & Belfiore sp. nov. and Phoriospongia mozambiquensis Calcinai & Belfiore sp. nov.) and four (Chondrosia corticata Thiele, 1900, Callyspongia (Cladochalina) aerizusa Desqueyroux-Faundez, 1984, Clathria (Thalysias) hirsuta Hooper & Levi, 1993 and Ciocalypta heterostyla Hentschel, 1912) are new records for the Indian Ocean. For Callyspongia (Euplacella) abnormis Pulitzer-Finali, 1993, Callyspongia (Callyspongia) pulitzeri Van Soest & Hooper, 2020 and Amphimedon brevispiculifera (Dendy, 1905) this represents the first record after their initial discovery. The majority of the species have a wide distribution in the Indo-Pacific Ocean, but species from South and East Africa have also been recorded. These data highlight the characteristic of Ponta do Ouro as a transitional zone, located between a tropical and temperate biogeographic province, as well as the importance of increasing biodiversity knowledge of this biogeographic border to monitor possible shifts in the area as a consequence of climate crisis.
The endozoic ciliates of the family Clevelandellidae Kidder, 1938 typically inhabit the hindgut of wood-feeding panesthiine cockroaches. To assess the consistency of species delimitation in clevelandellids, we tested the utility of three sources of taxonomic data: morphometric measurements, cell geometrical information, and 18S rRNA gene sequences. The morphometric and geometrical data delimited the clevelandellid morphospecies consistently and unambiguously. However, only Paraclevelandia brevis Kidder, 1937 represented a homogenous taxon in both morphological and molecular analyses; the morphospecies Clevelandella constricta (Kidder, 1937) and C. hastula (Kidder, 1937) contained two or three distinct, more or less closely related genotypes each; and the genetic homogeneity of the morphospecies C. panesthiae (Kidder, 1937) and C. parapanesthiae (Kidder, 1937) was not corroborated by the 18S rRNA gene sequences at all. Moreover, the 18S rRNA gene phylogenies suggested the C. panesthiae-like morphotype to be the ancestral phenotype from which all other clevelandellid morphotypes arose. The only exception was the C. constricta-like morphotype, which very likely branched off before the diversification of the C. panesthiae-like progenitor. The present molecular analyses also suggested that a huge proportion of the clevelandellid diversity still waits to be discovered, since examination of only four panesthiine populations revealed 10 distinct clevelandellid genotypes/molecular species.
A revision was done on the species of Enteromius Cope, 1867 (Cypriniformes: Cyprinidae) from the Lake Edward system with a smooth, flexible third unbranched dorsal fin ray without serrations. Specimens with these characteristics had previously been attributed to E. perince and E. stigmatopygus. A combination of a genetic (COI, mtDNA) and a morphometric approach was used. Based on the COI gene, we found two groups with a distance of 8.5%, though neither of the two corresponded to E. perince or E. stigmatopygus. One group revealed to be conspecific with E. alberti, previously a synonym of E. stigmatopygus, described from the Rutshuru River, May-Ya-Moto (DRC, Lake Edward system), and revalidated here. In addition, E. cercops, described from the Nzoia River (Kenya, Lake Victoria basin), is put in synonymy with E. alberti. The second group was most similar to E. mimus, but differed morphologically somewhat from the types of E. mimus. Therefore, specimens of this group were identified as E. cf. mimus. Morphologically, E. alberti can be separated from E. cf. mimus based on a higher number of lateral line scales and smaller values for interorbital width, pre-pelvic distance, body depth, maximum and minimum caudal peduncle depth, head width and head depth.
This paper reports on the genus Cobbionema Filipjev, 1922 in Sweden with the description of four species and a revision of the genus. Cobbionema acrocerca Filipjev, 1922 is relatively small in size, with a tail that has a conical proximal and a digitate distal section. Cobbionema cylindrolaimoides Schuurmans Stekhoven, 1950 is similar to C. acrocerca in most characters except having a larger body size and heavily cuticularized mandibles. Cobbionema brevispicula sp. nov. is characterised by short spicules and a conoid tail. Cobbionema acuminata sp. nov. is characterised by a long two-part spicule, a conical tail and three (one mid dorsal and two ventrosublateral) sharply pointed tines in the anterior chamber of the stoma that are located more anterior than in all the other species. We also present a molecular phylogeny of the family based on the nearly full-length 18S and the D2-D3 expansion segment of the 28S rRNA genes. Maximum Likelihood and Bayesian trees inferred from both genes strongly support a clade that included Cobbionema, Demonema Cobb, 1894 and Halichoanolaimus de Man, 1888 and another clade with Gammanema Cobb, 1920 and Latronema Wieser, 1954 nested together. None of the trees supported the monophyly of the subfamilies Choniolaiminae and Selachinematinae.
The area comprising the Pyrenees, Northeast Spain, Southern France and Corsica-Sardinia supports a large part of the diversity of Lumbricidae earthworms, including most species of the endemic genera Prosellodrilus, Cataladrilus and Scherotheca. In this region, the probability of encountering new species for science is significant, especially in scarcely sampled localities. In this study, we describe two unidentified species recently collected in the Hyères Archipelago (France), which we assigned to the genera Cataladrilus and Scherotheca based on morphological characters and molecular phylogenetic analyses. Other species of Scherotheca from Montpellier (including the type species of the genus, Sc. gigas gigas) were included in the analysis to clarify their conflicting systematics. A reduced molecular marker set (COI, 16S, 28S and ND1) proved as successful as larger marker sets for identifying phylogenetic relationships within the Lumbricidae. Remarkable disjunctions between both Cataladrilus porquerollensis Marchán & Decäens sp. nov., Scherotheca portcrosana Marchán & Decäens sp. nov. and their most closely related relatives, suggesting a strong influence of paleogeographic events on the earthworm fauna of the area and a possible role of near-shore islands as refugia for relict taxa. Genetic distances and branch lengths supported the elevation of some subspecies of Scherotheca to specific status as well as the retention of other subspecies, highlighting the importance of testing for such delimitation with molecular methods.
One individual referable to Calliopiidae G.O. Sars, 1893 was collected from a chemically reduced habitat, the hydrothermal vent systems in Okinawa Trough, and was identified as a new genus and species belonging to this family after a morphological examination. A formal description of this new species and a discussion of the relationship of the new genus within Calliopiidae are presented.
In this study, we examine 500 specimens of Anaplecta collected from China, of which 26 samples were used for COI sequencing. We confirm eight new species, i.e., Anaplecta corneola Deng & Che sp. nov., Anaplecta staminiformis Deng & Che sp. nov., Anaplecta arcuata Deng & Che sp. nov., Anaplecta strigata Deng & Che sp. nov., Anaplecta furcata Deng & Che sp. nov., Anaplecta cruciata Deng & Che sp. nov., Anaplecta nigra Deng & Che sp. nov. and Anaplecta bicolor Deng & Che sp. nov. based on morphological and molecular data using ABGD and GMYC analyses. The results of ABGD and GMYC were basically consistent with the morphospecies of Anaplecta. The intraspecific and interspecific genetic distances of Anaplecta ranged from 0 to 6.6% and 16.8% to 31.8%, respectively. We found the male genitalia of Anaplecta to exhibit intraspecific variation, especially in the phallomeres.
Sea pens (Cnidaria: Anthozoa: Pennatulacea) constitute a distinctive group of colonial marine invertebrates. They inhabit the world`s oceans, from shallow to deep waters. Studies about this group in Argentina are scarce, and no species have been described in the area in over a decade. Based on samples collected in Mar del Plata Submarine Canyon at about 3000 m deep we describe a new species of sea pen, Umbellula pomona Risaro, Williams & Lauretta sp. nov. This is a spiculate Umbellula that differs from other species of Umbellula with sclerites, by the number, development and distribution of the autozooids in its terminal cluster, as well as the shape of its axis. Molecular data also distinguishes it from other known species. Of the forty-three described species approximately ten are considered valid for the genus Umbellula, four of them are registered for the South Atlantic Ocean and only three are described for the Antarctic region. Since sampling efforts in this area have been scarce, the number of species of sea pens from the region is likely to increase substantially in the coming years.
Chaetopterus is a globally distributed genus of marine Annelida with a long history of taxonomic confusion. Here, we describe Chaetopterus bruneli sp. nov. from a depth of 350 m in the St. Lawrence Estuary, eastern Canada. The new species represents the northernmost record for Chaetopterus in the western Atlantic to date. The similar European species Chaetopterus norvegicus M. Sars, 1835 is resurrected from long-standing synonymy and redescribed from type material, and a lectotype is designated.
This paper treats the planthopper genus, Atracis Stål, 1866 (Flatidae: Flatoidinae) in China. Five new species, A. ocularia sp. nov., A. patefacta sp. nov., A. punctulata sp. nov., A. sphaerica sp. nov. and A. ungulata sp. nov., are described and a checklist of all its known species from China is provided.

Species are often presumed to be apparent in nature, but in practice they may be difficult to recognise, especially when viewed across continents rather than within a single site. Coalescent-based Poisson-tree-process (PTP) models applied to fast-evolving genes promise one quantitative criterion for recognising species, complete with the estimates of uncertainty that are required of a scientific method. Such methods face challenges especially in discerning between widespread polytypic species and complexes of closely related, restricted-range species. In particular, ‘over-sampling’ of many closely related individuals within one species could risk causing groups of less closely-related individuals within other species appearing relatively more distinct and consequently could risk them being interpreted falsely as separate species. Some of the most persistent taxonomic problems among bumblebees (genus Bombus Latreille, 1802) are within the subgenus Melanobombus von Dalla Torre, 1880. For a global revision of Melanobombus species, we use COI barcodes and seek to reduce the risk from localised over-sampling by filtering the data to include only unique haplotypes. Unique haplotypes give more conservative results than unfiltered data, but still increase the number of species in comparison with recent morphological treatments. After integrative assessment of COI coalescents in comparison with morphological groups, the number of accepted species shows a non-linear increase with sample size that plateaus to an increase of 47% (to 25 species) compared with a previous estimate (of 17) based on morphology alone. For the most widespread and variable species-complexes, our revised species improve the match to the patterns expected of species, both for genetic divergence-with-distance and for sympatry, leading to three main inferences. (1) The particularly widespread polytypic Bombus sichelii Radoszkowski, 1859, is a single species. (2) We detect two candidates for species within previous broad concepts of each of the former B. lapidarius (Linnaeus, 1758), B. miniatus Bingham, 1897, and B. rufofasciatus Smith, 1852. Within B. lapidarius s. lat. we find insufficient evidence to corroborate the candidate species, with no coalescent or morphological support for a recent claim for a separate species, B. bisiculus Lecocq, Biella, Martinet & Rasmont, 2019 described from southern Italy, but rather we find a weak and uncorroborated coalescent for a different and much broader group of samples from across southeastern Europe but excluding Turkey. Within the former broad concepts of B. miniatus s. lat. and B. rufofasciatus s. lat. the coalescent evidence is stronger and subtle evidence from morphology corroborates recognising B. miniatus s. str. and B. eurythorax Wang, 1892 stat. rev. as separate species as well as B. rufofasciatus s. str. and B. prshewalskyi Morawitz, 1880 stat. rev. as separate species. (3) Our coalescent and morphological results ‘split’ more clearly what has long been interpreted as a single polytypic B. keriensis Morawitz, 1887, s. lat., by supporting novel concepts of the restricted-range species: B. alagesianus Reinig, 1930 stat. rev., B. incertoides Vogt, 1911 stat. rev., B. keriensis s. str., B. qilianensis sp. nov., B. separandus Vogt, 1909 stat. rev., and B. tibeticus sp. nov. A lectotype is designated for the name B. keriensis and a neotype is designated for the name B. alagesianus. We estimate the phylogeny of Melanobombus species by including three slower-evolving genes to provide more evidence for deeper relationships, to estimate the time calibration of this phylogeny, and to estimate ancestral distributions, all within a Bayesian framework. We provide the first keys for identifying all of the species of Melanobombus.
The conspicuous Mediterranean brittle star Ophioderma longicauda (Bruzelius, 1805) has been discovered to represent a cryptic species complex, consisting of six nuclear clusters with contrasting reproductive modes (broadcast spawners and brooders). Here, O. longicauda is re-described. It is distinguished by a dark reddish-brown colouration both dorsally and on the ventral disc, and multiple tumid dorsal arm plates. One eastern Mediterranean brooding cluster is described as O. zibrowii sp. nov., characterized by a dark olive-green colour both dorsally and on the ventral disc, and single dorsal arm plates. Another brooder is described from Tunisia as O. hybrida sp. nov., with a highly variable morphology that reflects its origin by hybridization of O. longicauda and a brooder (possibly O. zibrowii sp. nov.), leaving the third brooding cluster as morphologically indistinguishable at this point and possibly conspecific with one of the others. The West-African O. guineense Greef, 1882 is resurrected as a valid species, differing morphologically from O. longicauda by predominantly single dorsal arm plates and light green or creamy white ventral side. Also from West Africa, O. africana sp. nov. is described, characterized by a dark brown colour, dorsally and ventrally, and single dorsal arm plates.
Based on an integrative taxonomic approach, a new species of the genus Loxosceles Heineken & Lowe, 1832, is described from the state of Hidalgo, Mexico. Loxosceles tolantongo sp. nov. is described based on DNA barcoding using cytochrome c oxidase subunit 1 (CO1) and internal transcribed spacer 2 (ITS2), and morphology. For species delimitation, four molecular methods were implemented: 1) corrected p-distances under neighbor joining (NJ); 2) automatic barcode gap discovery (ABGD); 3) general mixed yule coalescent model (GMYC) and 4) Bayesian Poisson tree processes (bPTP). The new species morphologically resembles L. jaca, another species from Hidalgo, but there are morphological differences mainly in the tibiae of the male palp, the seminal receptacles of the females and also the high genetic p-distances. CO1 was more informative than ITS2 for the genetic separation; however, both concatenated genes (CO1 + ITS2) present robust evidence for species delimitation. Loxosceles tolantongo sp. nov. is considered a unique species for four reasons: 1) it can be diagnosed and distinguished by morphological characters (of the male palps mainly, but also of the seminal receptacles of the females); 2) the genetic p-distances with CO1 were high (>10%); 3) the molecular species delimitation methods were congruent under CO1 and CO1 + ITS2; and 4) under CO1 and CO1 + ITS2, the new species is a putative sister group of L. jaca + L. tenango.
Nine new species of the South African endemic group of euryglossiform bees of the genus Scrapter Lepeletier & Serville, 1828 are described, thus bringing the total number of species to 29 in this species-group: Scrapter avontuurensis Kuhlmann sp. nov. ♀, S. bokkeveldensis Kuhlmann sp. nov. ♀, S. fynbosensis Kuhlmann sp. nov. ♀, S. hergi Kuhlmann sp. nov. ♂, S. keiskiensis Kuhlmann sp. nov. ♀, S. mellonholgeri Kuhlmann sp. nov. ♀♂, S. nitens Kuhlmann sp. nov. ♀, S. oubergensis Kuhlmann sp. nov. ♀ and S. willemstrydomi Kuhlmann sp. nov. ♂. The new replacement name S. punctulatus nom. nov. is proposed for S. punctatus Kuhlmann, 2014 which is a junior primary homonym of S. punctatus Lepeletier & Audinet-Serville, 1825 (= Allodape punctata [Lepeletier & Audinet-Serville, 1825]). Moreover, new records for already described taxa are presented and an updated key to all species of euryglossiform Scrapter is provided.
The present study evaluates the significance of Triassic ostracods from the Romanian Black Sea shelf as part of a project for the understanding of the palaeoceanographical evolution of the offshore extension of the North Dobrogean Orogen. The drill core CM31, sampled from the borehole 817 Lebăda Vest drilled on the western Romanian portion of the Black Sea shelf, contains sediments of Rhaetian, Late Triassic age. The taxonomy of ostracods obtained is discussed and adds to the scientific understanding of marine ostracods during the Rhaetian stage. We document 72 species, of which seven are new: Histriabairdia pontuseuxinusensis Forel gen. et sp. nov., Bairdiacypris argonautaii Forel sp. nov., Ceratobairdia? akhilleusi Forel sp. nov., Isobythocypris atalantella Forel sp. nov., Petasobairdia amazonella Forel sp. nov., Paracypris ovidi Forel sp. nov. and Pseudomacrocypris? kerabani Forel sp. nov. Histriabairdia Forel gen. nov. is introduced to accommodate species of the Triassic–Jurassic interval previously attributed to the modern genus Anchistrocheles. These assemblages point to an outer shelf environmental with relatively normal marine oxygenation. The oldest occurrence of Pokornyopsis, found in this material, indicates that this forerunner of modern troglobitic ostracods may not have been troglobitic in the Triassic.
Campodeinae is the most diverse subfamily of Campodeidae diplurans and inhabits soils and subsurface ecosystems. These are distributed in the Palearctic area, clearly rarifying towards northern latitudes. The major taxonomic characters are chaetotaxy, shape and complexity of pretarsal structures, and secondary sexual characters. This monograph provides a taxonomic revision of the subfamily Campodeinae in the Euro-Mediterrnean region, based on extensive literature review and new material studied. It comprises detailed morphological descriptions and illustrations together with habitat and distribution data of 161 species and 14 subspecies from 10 genera: Campodea Westwood, 1842, Edriocampa Silvestri, 1933, Eutrichocampa Silvestri, 1902, Helladocampa Condé, 1984, Libanocampa Condé, 1955, Litocampa Silvestri, 1933, Oreocampa Condé, 1950, Podocampa Silvestri, 1932, Remycampa Condé 1952, and Spaniocampa Silvestri, 1933. With 116 species Campodea is the most diverse and widely distributed genus in the studied area.
Dichromatobolus, a new genus of spirobolidan millipedes from Madagascar (Spirobolida, Pachybolidae)
(2020)
A new genus, Dichromatobolus gen. nov., belonging to the genus-rich mainly southern hemisphere family Pachybolidae of the order Spirobolida, is described based on D. elephantulus gen. et sp. nov., illustrated with color pictures, line drawings, and scanning electron micrographs. The species is recorded from the spiny bush of southwestern Madagascar. Dichromatobolus elephantulus gen. et sp. nov. shows an unusual color pattern, sexual dichromatism with males being red with black legs and females being grey. Males seem to be more surface active, as mainly males were collected with pitfall traps. Females mainly come from the pet trade. The body of this species is short and very wide, being only 8 times longer than wide in the males. Live observations show the species is a very slow mover, digging in loose soil almost as fast as walking on the surface. The posterior gonopods of Dichromatobolus gen. nov. are unusually simple and well-rounded, displaying some similarities to the genera Corallobolus Wesener, 2009 and Granitobolus Wesener, 2009, from which the new genus differs in numerous other characters, e.g., size, anterior gonopods and habitus. Despite several attempts with fresh tissue samples and different primers, molecular barcoding did not work for Dichromatobolus gen. nov. Any relationships to the other 15 genera of Pachybolidae indigenous to Madagascar remain unknown.
The Caucasian leucogeorgiinine genera Archileucogeorgia Lohmander, 1936 and Leucogeorgia Verhoeff, 1930 are revised, with Leucogeorgia being considered as a senior subjective synonym of Archileucogeorgia, syn. nov. The following new combinations are thus warranted: Leucogeorgia abchasica (Lohmander, 1936) and L. satunini (Lohmander, 1936), both comb. nov. ex Archileucogeorgia. All four previously described species, viz., L. longipes Verhoeff, 1930, L. abchasica, L. satunini and L. rediviva Golovatch, 1983, are redescribed based on new material, partly also on the type series, with a lectotype being designated for L. longipes. In addition, eleven new species of Leucogeorgia are described, both with normal (L. borealis sp. nov., L. gioi sp. nov., L. golovatchi sp. nov., L. lobata sp. nov., L. oculata sp. nov. and L. prometheus sp. nov.) and modified mouthparts (L. caudata sp. nov., L. mystax sp. nov., L. profunda sp. nov., L. redivivoides sp. nov. and L. turbanovi sp. nov., all clearly troglobionts). Additionally, a new monotypic genus, Martvilia gen. nov., is erected, with M. parva gen. et sp. nov. as the type species, another presumed troglobiont. An identification key to both genera and all 16 species of Caucasian Leucogeorgiini is presented. Several other members of this tribe are also re-examined, including a syntype male of Telsonius nycteridonis Strasser, 1976, from Greece, herewith designated as the lectotype. Troglomorphisms and mouthpart modifications, as well as the distributions and relationships within both Leucogeorgia and Leucogeorgiini, and a Leucogeorgiini species richness estimate for the western Caucasus are discussed.
Wenn man sich an die Frage eines möglicherweise spezifischen Schreibstils der sozialen Medien und seiner Auswirkungen auf Literatur heranwagt, sollte man nicht nur das 'Endprodukt', also den fertigen (Buch-)Text untersuchen, sondern vor allem auch die Bedingungen seiner Hervorbringung. Denn für das Entstehen eines neuen Stils der sozialen Medien spielt die Funktion des Kollektivs eine zentrale Rolle. In Analogie zur soziologischen Beschreibung aktueller urbaner Entwicklungen lassen sich die Beziehungen im Social-Media-Kollektiv als eine Form neuer Nachbarschaft beschreiben: Über die beschleunigte und intensivierte Interaktion in sozialen Netzwerken entstehen neue Geflechte und (virtuelle) Orte, an denen sich dieselben Personengruppen wiedertreffen, lesen und rezensieren - auch wenn sie in völlig unterschiedlichen Stadt- oder Weltteilen leben. Entsprechend können selbstverstärkende und selbstreferentielle Effekte durch Social Media auch für die Literaturproduktion und -rezeption untersucht werden: Markieren Retweets, angeheftete Posts und Hashtags neue Interessen- oder 'Stilgemeinschaften', die eigene Formen, aber auch Regeln und Zwänge ausbilden?
Euphorisch nahm das deutsche Feuilleton im letzten Sommer ein schmales Bändchen auf: Theodor W. Adornos "Aspekte des neuen Rechtsradikalismus". Ihm liegt ein von Adorno ursprünglich 1967 vor Wiener Studierenden gehaltener Vortrag zugrunde, in dem er auf den Einzug der NPD in einige deutsche Landesparlamente Ende der 1960er Jahre reagierte. Vorherrschend in den Besprechungen war der Verweis auf "erstaunliche Parallelen" zwischen dem Rechtsradikalismus der 1960er Jahre und den "gegenwärtigen Entwicklungen". [...] Magnus Klaue ist einer der wenigen Rezensenten, der in die Jubelrufe nicht einstimmt. In seiner Besprechung in der Frankfurter Allgemeinen Zeitung kritisiert er nicht Adornos Vortrag selbst, sondern die aus seiner Sicht "um den Preis der Enthistorisierung" allzu munter betriebene Parallelisierung der damaligen mit aktuellen politischen Entwicklungen. Klaue plädiert für die Einordnung von Adornos Vortrag in seinen zeitgeschichtlichen Entstehungskontext, da sich die Situation Ende der 1960er Jahre von der heutigen deutlich unterscheide.
Der Übergang vom 19. ins 20. Jahrhundert wurde von den Zeitgenoss*innen als markante Epochenwende erfahren. [...] Versteht man die Stil- und Kitschdiskurse um 1900 als aufeinander bezogen, erscheinen der "Wille nach Stil" und die Abwertung anderer ästhetischer Positionen als Kitsch allerdings nicht nur als Abgrenzungs- und Distinktionsversuche, sondern auch als Krisenlösungsstrategien zur Bewältigung der einschneidenden gesellschaftlichen wie ästhetischen Veränderungsprozesse der Epochenwende.
The genus Rudolfina Roháček, 1987 is revised and redefined with the description of the following nine new species, all from the New World: R. bucki sp. nov. (Mexico), R. exuberata sp. nov. (widespread, from USA to Brazil), R. howdeni sp. nov. (Mexico), R. megepandria sp. nov. (Mexico), R. newtoni sp. nov. (Mexico), R. pauca sp. nov. (Guatemala, Mexico), R. pilosa sp. nov. (Mexico), R. remiforma sp. nov. (Mexico) and R. tumida sp. nov. (Mexico, USA). Rudolfina is compared to closely related genera in the Archiceroptera genus complex, which in turn is recognized as part of a large, mostly Neotropical clade including Robustagramma Marshall & Cui, 2005, Pterogramma Spuler, 1924, Aptilotella Duda, 1924, Bitheca Marshall, 1987, Bromeloecia Spuler, 1924 and Archiceroptera Papp, 1977.
The new erigoninae genus Yuelushannus gen. nov. with two new species, Y. alatus sp. nov. (♂♀) and Y. barbatus sp. nov. (♂♀), are described from Hunan and Hubei Provinces. Detailed descriptions of somatic features and genitalic characters, photos of the habitus and copulatory organs, line drawings of copulatory organs and a distribution map are provided.
The genus Afrodonta s. lat. is shown to comprise several lineages with distinctive shell characters primarily associated with the microsculpture of the protoconch and teleoconch, and the manner in which the apertural barriers are deposited. These lineages comprise Afrodonta s. str. and five new genera: Amatholedonta gen. nov., Biomphalodonta gen. nov., Costulodonta gen. nov., Iterodonta gen. nov. and Phialodonta gen. nov. Twelve new species are described, doubling the diversity of aperturally dentate charopid snails known from southern Africa. All new species are narrow-range endemics. A new subspecies of one of the more widely distributed species of Afrodonta s. str. is also described. Keys to genera and species are provided. New species and subspecies: Afrodonta geminodonta sp. nov., Af. inhluzaniensis leptolamellaris subsp. nov., Af. mystica sp. nov., Af. pentodon sp. nov., Amatholedonta fordycei gen. et sp. nov., Biomphalodonta forticostata gen. et sp. nov., Costulodonta bidens gen. et sp. nov., C. pluridens gen. et sp. nov., Iterodonta ammonita gen. et sp. nov., Phialodonta agulhasae gen. et sp. nov., P. atromontana gen. et sp. nov., P. aviana gen. et sp. nov. and P. rivalalea gen. et sp. nov. New synonyms: Afrodonta bilamellaris londonensis Solem, 1970 = Afrodonta bilamellaris Melvill & Ponsonby, 1908. New combinations: Afrodonta acinaces Connolly, 1933, Afrodonta burnupi Connolly, 1933 and Afrodonta trilamellaris Melvill & Ponsonby, 1908 are transferred to Costulodonta gen. nov.; Afrodonta bimunita Connolly, 1939 is transferred to Amatholedonta gen. nov.; Afrodonta introtuberculata Connolly, 1933 and Afrodonta perfida Burnup, 1912 are transferred to Phialodonta gen. nov.
In the last few years, a sharp increase in the number of descriptions of new species of West African cone snails, particularly from the Cabo Verde Archipelago, has taken place. In previous studies, we used mitogenome sequences for reconstructing robust phylogenies, which comprised in total 120 individuals representing the majority of species (69.7%) described from this biogeographical region (except Angolan endemics) and grouped into seven genera within the family Conidae. Here, we add another 12 individuals representing endemic species that were missing in the previous studies. We use the phylogenies to identify monophyletic groups and a genetic divergence threshold (0.2% uncorrected p distance) to determine the number of valid species. As a result, the number of valid West African cone species could be drastically reduced to at least 40%, indicating that some recent poor-quality descriptions loosely based on phenotypic characters prone to convergence such as the shape and color patterns of the shell have contributed substantially to taxonomic inflation. Several previously accepted species with a reduced geographical distribution now become phenotypic forms of the remaining valid species, which increase their distribution ranges. In contrast, several cryptic species are now uncovered and described. For instance, Africonus insulae sp. nov. and Kalloconus canariensis sp. nov. are hereby introduced as new species. A detailed systematic account with illustrations and relevant information is presented. Lectotypes are designated for Conus trochulus and Conus irregularis, and neotypes for Conus crotchii and Conus diminutus. According to our results, it is strongly recommended that any future introduction of new taxa names for cone snails from West Africa should be supported by molecular and/or anatomical rather than exclusively shell morphological data. The taxonomic decisions here taken have direct implications for conservation and will eventually require re-evaluation of the Red List risk status of an important number of species.
In Deutschland ist die Wohneigentumsquote innerhalb der OECD am zweitniedrigsten. Eine wichtige Rolle spielt dabei die Wohnungspolitik, die hierzulande Anreize für das Mieten schafft. Neue Studien zeigen, dass eine veränderte Politik die Wohneigentumsquote erhöhen und die Vermögensungleichheit verringern könnte.
Three new species of aulacid wasps, Aulacus pascali sp. nov., Pristaulacus elveni sp. nov. and Pristaulacus villemantae sp. nov., and a new species of gasteruptiid wasp, Gasteruption jenningsi sp. nov., are described and figured. Additionally, we update identification keys to New Caledonia species of aulacids and gasteruptiids. We also provide new data on New Caledonian Evaniidae, Gasteruptiidae and Stephanidae.
Five new species of Meta Koch, 1836 (Araneae: Tetragnathidae) from Gaoligong Mountains, China
(2020)
Five new species of the genus Meta C.L. Koch, 1836 from the Gongligong Mountains, Yunnan are described: Meta hamata sp. nov. (♂♀), M. longlingensis sp. nov. (♂), M. tangi sp. nov. (♂♀), M. yani sp. nov. (♂♀) and M. yinae sp. nov. (♂♀). Detailed descriptions of somatic features and genitalic characters, photos of the body and genital organs, line drawings of the copulatory organs and distribution maps are provided.
Abiinae is the second-largest subfamily in Cimbicidae, a small family of true sawflies (Tenthredinoidea). The subfamily is adequately defined, but the generic classification has been unstable. Currently, only two genera are regarded as valid: Abia Leach, 1817 and Allabia Semenov & Gussakovskij, 1937. We evaluate the generic classification of Abiinae in a phylogenetic context. A total of 32 species (out of 57 described for the subfamily), including the type species of Allabia, Allabia infernalis (Semenov, 1896), are scored for 150 adult morphological characters. Results show some resolution, but only few clades can be circumscribed by consistent character combinations. Most of the characters that have previously been used to define genera are not congruent; consequently, most suggested genus definitions appear to be random character state combinations and few natural groups can be identified. For these reasons, we treat Allabia syn. nov. as a junior synonym of Abia and make the following additional taxonomic changes: Abia infernalis Semenov, 1896 comb. rev. and Abia malaisei (Semenov & Gussakovskij, 1937) syn. nov. For the purpose of long-term stability of the classification of Abiinae, we recommend recognizing only one genus, Abia, within the subfamily.
Bevor Wolodymyr Selenskyj vor einem Jahr Präsident der Ukraine wurde, war er dies schon einmal gewesen, und zwar in seiner Rolle in der erfolgreichen Fernsehserie "Sluha narodu" ("Diener des Volkes"). Hier zeichnet sich nicht nur ein neues Verhältnis von digitaler Wirklichkeit und politischer Öffentlichkeit ab, sondern auch eine neue Form des Populismus, die nicht auf nationalistische Diskurse und reaktionäre Denkmuster baut, sondern antistaatliche und neoliberale Affekte miteinander verbindet.
After the examination of a large collection of Oniscidea from caves in the Brazilian states of Bahia, Minas Gerais, Pará, Sergipe and São Paulo, 12 species were recognized in the families Philosciidae and Scleropactidae. Four new species are described: Alboscia jotajota sp. nov. from the Açungui group; Androdeloscia akuanduba sp. nov. and Amazoniscus spica sp. nov. from the Carajás Formation; and Metaprosekia igatuensis sp. nov. from the Quadrilátero Ferrífero karst region. In addition, Atlantoscia inflata, Benthana longicornis, B. olfersii, B. picta and Paratlantoscia rubromarginata (Philosciidae) are recorded from Brazilian caves for the first time; and Benthana iporangensis, B. taeniata and Circoniscus bezzii (Scleropactidae) have the knowledge of their distribution extended to cave habitats.
Cloeon perkinsi was described from South Africa in 1932 by Barnard. Despite being relatively common in Africa, it was mentioned in the literature quite rarely, and its known distribution to date includes most of sub-Saharan Africa. Material collected recently in Ethiopia, Israel, Saudi Arabia, and Yemen extends its distribution in East Africa, Arabian Peninsula and the Levant. We examined this material, and provide a re-description of adults (females and males) and nymphs of the species. It represents a much-needed urge mainly due to inconsistencies in literature reports regarding colouration, and sometimes incomplete morphological description of all stages. We demonstrate the intraspecific morphological variability that we have witnessed, and provide information regarding the range of habitats colonised by C. perkinsi. Based on geological and climatic history of the studied region, taken together with among countries genetic distances of the mitochondrial barcoding gene COI, we propose colonisation mechanisms for the north-easternmost limit of distribution. The fragmented distribution pattern of the species highlights the conservation importance of isolated aquatic habitats in the region, as well as current knowledge gaps.
A new genus of Baetidae is described from Southeast Asia, Procerobaetis gen. nov. It has a wide distribution reaching from Indonesia (Sumatra) to the Philippines. Two new species are described from Indonesia, P. leptobranchius gen. et sp. nov. and P. petersorum gen. et sp. nov., and one new species from the Philippines, P. freitagi gen. et sp. nov. Procerobaetis gen. nov. is characterized by having seven pairs of elongate, apically pointed gills. At least gills I and II are very slender with strongly extended points, which is unique in Baetidae. Similar gills were described from Leptophlebiidae. Procerobaetis gen. nov. is further characterized by having long, slender legs with extended, slender and slightly bent claws. The antennae posess remarkable spines at the outer, lateral margin, which are maximally developed on segments IX–XI of the flagellum. No spines are present on the posterior margins of abdominal tergites I–VI. COI sequences were obtained from all three of the new species. The genetic distances (Kimura 2-parameter) between these species are between 13% and 20%. Very limited genetic distances of 0% to 1% were found between specimens of the same species. The occurrence of two different species in the same area of Sumatra is discussed.
Blickte Carl Schmitt dieser Tage auf Georgien, so müsste er seinen berühmten Anfangssatz aus dem dritten Kapitel der "Politischen Theologie" ändern. Statt "Souverän ist, wer über den Ausnahmezustand entscheidet", müsste es heißen: Souverän ist, wer sich dem Ausnahmezustand nicht beugt. Denn die Georgische Orthodoxe Kirche hat erklärt, sich notfalls über alle vom Staat im Zusammenhang mit der Corona-Krise verhängten Beschränkungen hinwegzusetzen, um Liturgien und vor allem die Kommunion feiern zu können - so geschehen bei den Ostermessen am letzten Sonntag. [...] Der Konflikt ist jedoch nicht nur rechtlich, sondern auch politisch sehr bedeutsam. Politisch geht es um die freiheitliche demokratische Grundordnung Georgiens und den Versuch der Kirche, diese zu untergraben. Die Orthodoxe Kirche Georgiens, Ende der 1980er Jahre noch eine randständige gesellschaftliche Kraft, ist zu einer der reichsten und mächtigsten Institutionen in Georgien aufgestiegen, der die Mehrheit der georgischen Gesellschaft vertraut und die deshalb großen politischen Einfluss ausübt.
Merab Mamardaschwili (1930–1990) ist ein, wenn nicht der bedeutendste Philosoph aus der Sowjetunion. Der "georgische Sokrates" (Jean-Pierre Vernant) genießt in seiner georgischen Heimat und in Russland, wo er mehrere Generationen von Philosoph*innen beeinflusst hat, beinahe kultische Verehrung. Mamardaschwilis Philosophie aber wurde von seinem Kultstatus geradezu erdrückt: Er ist als philosophische Pop-Ikone in Georgien und Russland allgegenwärtig, er wird bewundert, passend oder unpassend zitiert, aber wenig gelesen. Außerhalb der ehemaligen Sowjetunion ist er weitgehend unbekannt geblieben, in deutscher Übersetzung liegen nur einzelne Vorträge und Aufsätze vor. 30 Jahre nach seinem Tod am 25. November 1990 wäre es die beste Würdigung, ihn von seinem Denkmalstatus zu befreien und als einen Philosophen wiederzuentdecken, mit dem die Fragen an die Gegenwart anders zu stellen und möglicherweise auch zu beantworten sind.
The Neotropical frog genus Pseudopaludicola includes 25 species distributed throughout South America. Herein we review the taxonomic status of P. parnaiba relative to P. canga and the specific identity of the population treated in previous studies as Pseudopaludicola sp. 3 from Barreirinhas in the Brazilian state of Maranhão. The lack of differentiation in advertisement call, morphology, and mitochondrial markers from topotypes and different populations rejects the status of P. parnaiba and Pseudopaludicola sp. 3 from Barreirinhas as distinct species. For these reasons, we suggest to formally consider P. parnaiba as a junior synonym of P. canga. We also found that a population previously reported as P. facureae from central Brazil (Palmeiras de Goiás, Goiás) corresponds to a cryptic species that we describe here as a new species. Lastly, we provide for the first time the phylogenetic positions of P. giarettai, P. llanera and P. pusilla.
Revision of the endemic Malagasy leafhopper tribe Platyjassini (Hemiptera: Cicadellidae: Iassinae)
(2020)
The leafhopper tribe Platyjassini, endemic to Madagascar, is revised, largely based on specimens obtained in a recent bioinventory project led by the California Academy of Sciences. Platyjassini was previously known based on the type genus, Platyjassus Evans, 1953, and four described species. Betsileonas marmorata (Blanchard, 1840), the largest leafhopper recorded from Madagascar, presently known from a few specimens collected > 100 years ago and recently considered a genus and species incertae sedis within Cicadellidae, is newly placed in Platyjassini. Fourteen new genera and 54 new species are described and illustrated, and three new combinations are proposed. Pachyjassus gen. nov. includes three new species: Pachyjassus alatus sp. nov., Pachyjassus basifurcatus sp. nov. and Pachyjassus ranomafanensis sp. nov. Pallijassus gen. nov. is erected to include two species previously placed in Platyjassus, Pallijassus reticulatus (Evans, 1959) comb. nov. and Pallijassus stenospatulatus (Evans, 1959) comb. nov. Petalojassus gen. nov. includes one new species, Petalojassus ochrescens sp. nov. Phaiojassus gen. nov. includes seven new species: Phaiojassus acutus sp. nov., Phaiojassus bispinosus sp. nov., Phaiojassus constrictus sp. nov., Phaiojassus grandis sp. nov., Phaiojassus spatulatus sp. nov., Phaiojassus undulatus sp. nov. and Phaiojassus unispinosus sp. nov.

Platyjassella gen. nov. includes six new species: Platyjassella ancora sp. nov., Platyjassella andohahelensis sp. nov., Platyjassella attenuata sp. nov., Platyjassella cormorana sp. nov., Platyjassella emarginata sp. nov. and Platyjassella immaculata sp. nov. Platyjassula gen. nov. includes four new species: Platyjassula cyclura sp. nov., Platyjassula heterofurca sp. nov., Platyjassula isofurca sp. nov. and Platyjassula mahajangensis sp. nov. In addition to the type species, Platyjassus viridis Evans, 1953, Platyjassus includes 11 new species: Platyjassus acutus sp. nov., Platyjassus asymmetricus sp. nov., Platyjassus fisheri sp. nov., Platyjassus griswoldi sp. nov., Platyjassus harinhalai sp. nov., Platyjassus irwini sp. nov., Platyjassus pedistylus sp. nov., Platyjassus pennyi sp. nov., Platyjassus pictipennis sp. nov., Platyjassus symmetricus sp. nov. and Platyjassus vestigius sp. nov. Plerujassus gen. nov. includes one new species, Plerujassus brunnescens sp. nov., in addition to Plerujassus appendiculatus (Evans, 1959) comb. nov., previously placed in Platyjassus. Plexijassus gen. nov. includes one new species, Plexijassus caliginosus sp. nov. Pseudocurtara gen. nov. includes three new species: Pseudocurtara minima sp. nov., Pseudocurtara nigripicta sp. nov. and Pseudocurtara quadrata sp. nov. Pseudocyrta gen. nov. includes one new species, Pseudocyrta hyalina sp. nov. Pseudomarganana gen. nov. includes two new species: Pseudomarganana olivacea sp. nov. and Pseudomarganana rosea sp. nov. Pulchrijassus gen. nov. includes eight new species: Pulchrijassus anjozorobensis sp. nov., Pulchrijassus eunsunae sp. nov., Pulchrijassus pallescens sp. nov., Pulchrijassus roseus sp. nov., Pulchrijassus rubrilineatus sp. nov., Pulchrijassus sindhuae sp. nov., Pulchrijassus talatakelyensis sp. nov. and Pulchrijassus toamasinensis sp. nov. Punctijassus gen. nov. includes three new species: Punctijassus circularis sp. nov., Punctijassus compressus sp. nov. and Punctijassus ivohibensis sp. nov. Illustrated keys to genera and species are provided.
Five new species of Peltonotellini (Caliscelinae) are described and illustrated: Bruchomorpha pseudodorsata sp. nov., Fitchiella brachyrhina sp. nov., Protrocha nigrilutea sp. nov. and P. punctatosa sp. nov. from Mexico, and Fitchiella zahniseri sp. nov. from Panama. Additionally, five previously described species are redescribed based on newly collected specimens: Aphelonema brevata Caldwell, 1945 (proposed original combination), Bruchomorpha decorata Metcalf, 1923, Bruchomorpha mormo Kirkaldy, 1907, Nenema virgata (Doering, 1941) and Protrocha nesolitaria (Caldwell, 1945). Bruchomorpha decorata is recorded from Panama for the first time. Redescriptions provide new information on the distribution of sensory pits and the first detailed descriptions of male and female terminalia for these species.
Jean-Luc Nancy ist einer der bekanntesten zeitgenössischen Philosophen Frankreichs. Stark beeinflusst von Martin Heidegger, Georges Bataille und Jacques Derrida, setzt er sich in seinen zahlreichen Schriften vor allem mit der deutschen Philosophie und Literatur auseinander. Das Gespräch wurde im September 2020 per E-Mail auf Französisch geführt.
Ein Vergleich der beiden Biographien Warburgs, der vollendeten von Gombrich und der unvollendeten von Bing, dürfte angesichts der offensichtlichen Differenzen ihrer beider Sichtweisen wenig ertragreich sein. Allerdings ist Bing, die eine enge Vertraute Warburgs war, etwas Wichtiges aufgefallen, das Gombrich entgangen ist und auch von weiten Teilen der darauffolgenden Literatur nicht zur Kenntnis genommen wurde: Warburg hatte Ludwig Traube, den Begründer der modernen Paläographie, als "Großmeister unseres Ordens" bezeichnet. Diese amüsante Ehrerbietung mit ihren freimaurerischen Untertönen hat weitreichende hermeneutische Implikationen, die von Bing mit großem Scharfsinn entwickelt wurden. Hierzu stellen meine folgenden Überlegungen eine Ergänzung dar.
The paper presents new odonatological data from the formerly unstudied islands Patnanungan and Jomalig as well from the northeastern part of Polillo, The Philippines. Four species are new for the PolilloIsland group, including one new taxon Anax parthenope julius – for The Philippines. Currently, 78 odonate taxa are known from the Polillogroup.
Using a qualitative sampling approach to survey for Odonata along water systems inside and outside of four major protected areas in Southern Ghana (viz; Atewa Range Forest Reserve, Ankasa Forest Reserve, Owabi Wildlife Sanctuary and Bobiri Forest Reserve), a total of 66 Odonata species in seven families encompassing 28 Zygoptera and 38 Anisoptera were recorded. Libellulidae (n= 36) exhibited the highest number of species, followed by Coenagrionidae (n= 10), and Calopterygidae (n= 5). In considering the observed number of species exhibited by each protected area, the Atewa Range Forest Reserve exhibited the highest number of species (n= 51), followed by the Ankasa Forest Reserve (n= 47), the Owabi Wildlife Sanctuary (n= 44) and Bobiri Forest Reserve (n= 43). Disturbance tolerance species dominated in habitats outside the various forest reserves, whiles forest specialists predominated inside the reserves, indicating the quality of the forest cover therein.
This paper presents the faunistic results of three short field excursions conducted in spring and early summer of 2018 in Kosovo, considering dragonfly fauna one of the most understudied countries of Europe. This study presents first systematic dragonfly research in Kosovo. Within a total of 13 field days between end of April and end of June 2018, 60 sites were surveyed and 44 dragonfly species were found. Significant results include the first documented report of 15 species for Kosovo. New data on several other species with a broader European concern or generally rare on the West Balkan peninsula, i.e. Coenagrion ornatum, Anax ephippiger, Caliaeschna microstigma, Cordulegaster heros, C. bidentata, Somatochlora flavomaculata, and Sympetrum flaveolum, are also presented. The overview of all visited sites is included. Altogether, 47 dragonfly species are now reported for Kosovo.
We report here the results from field trips to collect Odonata in the northeastern parts of Kelantan state and the north of Terengganu state, Peninsular Malaysia. Eighty four species were collected, and four of these are new records for the state Kelantan and 10 are new records for the state of Terengganu. Notable records obtained from the field trips were Euphaea masoni, Coeliccia sameerae, Pseudagrion ?lalakense, Leptogomphus tioman and Macromia cupricincta. Checklists for Kelantan (140 species) and Terengganu (132 species) are given in an appendix.
Arising from a number of 2019 IUCN Red List assessments for a subset of Chinese Odonata, a series of corrections and taxonomic revisions were made to the World Odonata List. The rationale for these amendments is provided here. Paragomphus wuzhishanensis Liu, 1988 is shown to be a junior synonym of Paragomphus pardalinus Needham (1942). Epophthalmia kuani Jiang 1998 is synonymised as a junior synonym of Epophthalmia. elegans (Brauer, 1865) and Epophthalmia bannaensis Zha & Jiang, 2010 is treated as a junior synonym of Epophthalmia vittata Burmeister, 1839. Idionyx pseudovictor Xu, 2013 is shown to be junior synonym of Idionyx claudia Ris, 1912 and Sympetrum anomalum Needham, 1930 is treated as a junior synonym of Sympetrum maculatum Oguma, 1922.
Previously unpublished records of Odonata from the states of Negeri Sembilan and Selangor in Peninsular Malaysia are presented. One hundred and eight species are listed, of which 77 were collected in Negeri Sembilan and 87 in Selangor. Fifteen of the species recorded from Negeri Sembilan and seven of those recorded from Selangor appear to be first records for the respective state. Notable records include Drepanosticta sp. cf hamadryas Laidlaw, 1931, Rhinocypha pelops Laidlaw, 1936, Acrogomphus ?malayanus Laidlaw, 1925, Heliogomphus kelantanensis (Laidlaw, 1902); Onychogomphus duaricus Fraser, 1924, Macromia cupricincta Fraser, 1924, Idionyx montana Karsch, 1891, Chalybeothemis chini Dow, Choong & Orr, 2007 and Hylaeothemis clementia
Ris, 1909 Ris, 1909. Provisional checklists of the Odonata known from Selangor plus the
Federal Territory of Kuala Lumpur (171 species) and for Negeri Sembilan (116 species)
are given in appendices.
An explanation is presented for each of the 135 scientific names given to Odonata by F. M. Brauer (fossils and synonyms included), in addition the names of the actual genera in which Brauer’s species are now classified are explained. Prior to that part biographical information is given and Brauer’s merits in enlightening the taxonomy of dragonflies are analysed. Conclusions are drawn as to his preferences in odonatological nomenclature and finally the difficulties are discussed, which Brauer had to face in his taxonomic work.
The changes in coloration with age in males and females of Coeliccia mattii Phan & Kompier, 2016 from the Central Highlands of Vietnam are documented. Immature forms have extensive yellow markings on the thorax and S9 is yellowish, while in the fully mature male form, the thorax is largely black and covered in pruinosity and S9 is completely black. S9 is yellowish in the immature female while S9 is black in the fully mature female.
Wenn verschiedene Sprachen, Literaturen und Kulturen in mehrsprachigen Räumen und Situationen und in intertextuellen Dialogen miteinander in Beziehung treten, entsteht ein kreatives Potential, das der karibische Schriftsteller Patrick Chamoiseau als 'actif relationnel' bezeichnet: " La communauté est désormais dans l'actif relationnel des langues, des cultures et des hommes ". Wie lässt sich diese Idee für die literarische Komparatistik fruchtbar machen, zu deren Aufgaben es gehört, die komplexen Beziehungen zwischen verschiedenen Sprachen, Literaturen und Kulturen zu untersuchen? Mit welchen sprachlichen und poetischen Verfahren wird es in der literarischen Praxis mobilisiert, mit welchen Methoden kann man ihm auf analytischer und theoretischer Ebene gerecht werden? Im vorliegenden Band wird die Kreativität und Komplexität dieses Relationspotentials an einem breiten Spektrum von Sprachen und literarischen Werken aus aller Welt aufgezeigt.
We present a comprehensive revision of the pholcid spider collection of M.A. González-Sponga, who between 1998 and 2011 described 22 new genera and 51 new species of Pholcidae from Venezuela. In addition, we treat the pholcid material collected during three expeditions to Venezuela conducted between 2002 and 2020. Of González-Sponga’s pholcid taxa we recognize three genera and 24 species as valid. We describe 43 new species (all from males and females) in one new and 13 previously described genera; four genera are newly recorded for Venezuela. We describe the previously unknown females of 15 species, present new records for 46 previously described species, synonymize one genus and one species, and correct numerous minor errors in previous publications on Venezuelan pholcids. At the generic level, the Venezuelan pholcid fauna now appears fairly well known, but available data on distribution and endemism suggest that many species remain undiscovered and undescribed. Despite the obvious gaps, our data are congruent with previous studies on other taxa that have the highest levels of endemism in the Venezuelan Andes, the Coastal Ranges, and the Guyana Highlands. The Falcón Region in particular shows a complex mosaic of biogeographic relationships with other regions. We provide new biological data on numerous species. We document the first cases of evolutionary microhabitat shifts in the genera Mecolaesthus Simon, 1893 and Priscula Simon, 1893. We document several cases of close congeners sharing localities, usually in slightly to conspicuously different microhabitats, sometimes apparently in identical microhabitats. We document several cases of color polymorphism, mostly intersexual, in Metagonia conica (Simon, 1893) both intersexual and among males. We document further cases of two rare phenomena in Pholcidae: use of specific non-silken structures for retreats (in Pisaboa Huber, 2000) and egg parasitism (in Priscula).
Das Periodical "Medienkomparatistik" eröffnet ein neues Forum für vergleichende Medienwissenschaft. Das Zusammenwirken unterschiedlicher Medien und verschiedener medialer Praktiken spielt nicht nur in der gegenwärtigen Alltagswelt eine zunehmend bedeutende Rolle. Vielmehr hat sich in den letzten Jahren, ausgehend von den literatur-, kunst-, und medienwissenschaftlichen Einzeldisziplinen ein fächerübergreifendes Diskussionsfeld herausgebildet, das sich gezielt Fragen des Medienvergleichs und der Interferenz von Medien widmet. Dieser interdisziplinäre Forschungsbereich erlebt derzeit in den Kulturwissenschaften eine erstaunliche Konjunktur. Neben der vergleichenden Methodologie als wichtige heuristische Grundlage besteht eine weitere Zielsetzung der Medienkomparatistik darin, allgemeine Kriterien zur systematischen Erfassung der einzelnen Medien zu entwickeln und ihre jeweiligen Operationsleistungen in sich wandelnden kulturellen Kontexten zu erkunden. Dabei soll ein weites Spektrum medialer Formen und Verfahren einbezogen werden, das von analogen und digitalen Bild- und Schriftmedien über dispositive Anordnungen bis hin zu diskursiven Wissensformationen reicht. Welche spezifischen Eigenschaften zeichnen einzelne Medien aus, was trennt und was verbindet sie? Welche produktiven Austauschbeziehungen ergeben sich aus medialen Konkurrenzen und Konvergenzen? Wie lassen sich historische Transformationen medialer Praktiken und Ästhetiken erfassen? Wie können mediale Verhältnisbestimmungen medientheoretisch neu konturiert werden? Das Periodical erscheint zunächst jährlich in einem Band von ca. 200 Seiten. Da es in einem interdisziplinären Forschungsbereich angesiedelt ist, richtet es sich an verschiedene kulturwissenschaftliche Fachgruppen, wie zum Beispiel Komparatistik, Medienwissenschaft, Kunstgeschichte sowie einzelne Philologien wie Anglistik, Germanistik, Romanistik etc.
