The genus Cyparium Erichson, 1845 (Staphylinidae, Scaphidiinae, Cypariini) comprises 55 species, distributed mainly in the Neotropical and Oriental regions. Twenty-four species are known from the Neotropical region, but only eight species are reported from Brazil. In this paper we describe five new species and redescribe two species of Brazilian Cyparium, as follows: Cyparium achardi sp. nov., C. lescheni sp. nov., C. loebli sp. nov., C. newtoni sp. nov., C. pici sp. nov.; Cyparium collare Pic, 1920; and Cyparium oberthueri Pic, 1956. We provide images of adult males and females and their dissected parts, and information on host fungi whenever available. We also provide a comparative plate of dorsal colour patterns of Neotropical Cyparium.
Discodon tricolor (Guérin-Méneville, 1832) was thought to be a common species widely distributed in the Atlantic Forests of Brazil, yet showing morphological and chromatic variations. After examination of a large number of specimens from different regions of the Atlantic Forest biome, we found that Discodon tricolor actually represents a complex of many similar and sometimes sympatric species. Thirteen species in this complex are recognised as valid: Discodon tricolor, D. neoteutonum sp. nov., D. vanini sp. nov., D. obscurior Pic, 1906 stat. nov., D. lineaticorne sp. nov., D. aurimaculatum sp. nov., D. marginicolle sp. nov., D. tenuecostatum sp. nov., D. nigrocephalum Pic, 1949, D. tamoio sp. nov., D. viridimontanum sp. nov., D. crassipes Wittmer, 1952, and D. testaceipes Pic, 1930 stat. nov. The species Discodon albonotatum Pic, 1906 is confirmed as a synonym of D. tricolor, while the subspecies D. albonotatum obscurior and D. albonotatum testaceipes are elevated to specific status. The subgenus Acanthodiscodon Wittmer, 1952 is synonymised with Discodon Gorham, 1881. All the species are described and illustrated in detail and an identification key is provided. Despite being chromatically similar, the species show major morphological differences in their aedeagus and antennal structures, suggesting that they do not form a monophyletic clade. A potential mimicry ring involving these species of Discodon as well as other members of Cantharidae, Lampyridae, Cerambycidae and Belidae is discussed. Comments are made on the conservation of these species and their habitats within the Atlantic Forest biome.
Seven new species of the genus Meta C.L. Koch, 1836 from Southwest China are described here: M. bowo sp. nov. (♂♀), M. cona sp. nov. (♂♀), M. gyirong sp. nov. (♂), M. hongyuan sp. nov. (♂♀), M. tibet sp. nov. (♂♀), M. wanglang sp. nov. (♂♀) and M. weining sp. nov. (♂♀). Detailed descriptions, photos of somatic features and copulatory organs as well as line drawings, comparisons with closely related species, and a distribution map are provided.
Rhytidaphora Reshchikov & Quicke gen. nov. (type species Rhytidaphora thailandica Reshchikov & Quicke gen. et sp. nov.) from Thailand is described and illustrated. It belongs to the tribe Euryproctini of the subfamily Ctenopelmatinae (Hymenoptera, Ichneumonidae) based on the absence of glymma and the subapical notch on the ovipositor. The new taxon differs from all other genera of Euryproctini by the occipital carina being broadly incomplete dorsally, the hypostomal carina joining the occipital carina shortly before the base of the mandible, distinctly pectinate tarsal claws, and immovably fused and strongly sculptured second and third metasomal tergites.
A new lichen species Lecaimmeria pakistanica K.Habib, R.Zulfiqar & Khalid sp. nov. is described and illustrated from rocks in the temperate forests of the Himalaya of Azad Jammu and Kashmir, Pakistan. This species is characterized by its yellow-brown to brown thallus having areoles 0.4 to 1.5 mm across, branched and anastomosing paraphyses, a tall hymenium, large ascospores 20–32 × 10–16 μm, and no substance detected by thin layer chromatography. All other species of the genus have ascospore dimensions in the range of 14–22 × 5–14 μm. A phylogenetic analysis is provided based on ITS nrDNA sequences, and supports the separation of the novel species. Photographs and a comparative analysis with related species of Lecaimmeria are provided to confirm the status of the species.
The Chapada dos Veadeiros National Park is a conservation unit established to preserve the highest savannahs of Central Brazil and their unique biodiversity. Eriocaulaceae are a relevant and conspicuous family in such high savannahs, but its diversity is poorly known, documented solely in general lists or in isolated efforts aimed at small groups. After a structured series of field expeditions and analysis of specimens from the relevant herbaria, we provide nomenclatural novelties, a first identification key, and an illustrated checklist for the species of Paepalanthoideae (Eriocaulaceae) in the area. We recorded 42 species of Paepalanthoideae from the Chapada dos Veadeiros National Park: Actinocephalus (Körn.) Sano (2 spp.), Comanthera L.B.Sm. (1 sp.), Paepalanthus Mart. (24 spp.), and Syngonanthus Ruhland (15 spp.). Actinocephalus brevifolius Trovó & Echtern. sp. nov. and P. irwinii Trovó & Echtern. sp. nov. are newly described species and P. politus Trovó stat. et nom. nov. is a variety of P. elongatus (Bong.) Körn. raised to the species status with a new name. The generic and specific composition shows predominance of Paepalanthus and Syngonanthus, and with a low representation of Actinocephalus and Comanthera, as expected, outside of the Espinhaço Range. More than 50% of the species (22 spp.) are endemic to the area and 25 species are endemic to Central Brazil, the area being the main center of diversity for dimerous-flowered groups. The non-endemic diversity is a combination of widespread species and marginal distribution of species typical from the Amazon and southeastern savannahs. The species are unevenly distributed in the area, with their occurrence correlated to altitude, water availability, and lithology. We reinforce that the savannahs from Central Brazil are a secondary center of diversity for Eriocaulaceae, playing a central role in the conservation of an unique and irreplaceable piece of its diversity and the Cerrado biome as well.
The genus Cottus contains more than 60 species that are common in freshwater bodies of northern Eurasia and North America. Despite the abundance of species, this genus has been insufficiently studied in Eastern European rivers and lakes. The new taxon Cottus cyclophthalmus sp. nov. was found in the Neman/Nemunas and Venta river systems (Baltic Sea Basin). Cottus cyclophthalmus is sister and most morphologically similar to Cottus gobio. The new species has the following diagnostic characters: round, protruding (tubular) eyes near front of head; dermal papillae on top and sides of head, naked body, absence of bony prickles, full trunk canal with 32–36 pores. The description of Cottus cyclophthalmus and a new finding of Cottus microstomus improved understanding of the Eastern European biodiversity.
The formerly monotypic genus Paranecepsia Radcl.-Sm. is expanded with the description and illustration of a second species, Paranecepsia andrafiabensis Barberá & O.Lachenaud sp. nov. Molecular phylogenetic analyses of plastid rbcL and trnL-F data confirm a sister relationship between the new species and P. alchorneifolia Radcl.-Sm., as members of the alchorneoids clade. Paranecepsia andrafiabensis sp. nov. is notable for expanding the character states for the genus (now including both 2- and 3-locular ovary species) and broadening the geographic range of the genus from continental Africa to Madagascar. The new species adds to the diverse karst limestone endemics of northwestern Madagascar, where it has a very restricted distribution at the base of the western wall of the Ankarana tsingy. An amended generic description of Paranecepsia and a key to the species are also presented. Paranecepsia andrafiabensis sp. nov. is provisionally assessed as VU D1 based on the IUCN Red List criteria.
Two new opilionid species from suborder Cyphophthalmi, family Sironidae, Siro franzi Karaman & Raspotnig sp. nov. and Siro ozimeci Karaman sp. nov., from Austria and Croatia respectively, are described and illustrated. Both species show a close relation to two other relict sironid species from the southern and eastern parts of the Alps, Siro valleorum and Siro crassus. All four species are treated here as a monophyletic, alpine group of genus Siro, opposed to the remaining two European sironids, S. rubens and S. carpaticus (palaeoeuropean Siro group). The history of the alpine Siro group parallels the history of a part of the dynamic European archipelago in the Mediterranean Tethys area, which became a part of the Alpine orogeny. Diversification of the alpine Siro group is the result of the orogenic evolution of the Alps, linked to the Austroalpine and South Alpine tectonic units.
Temnothorax (Myrmicinae, Crematogastrini) is one of the most diverse Holarctic ant genera, and new taxonomic advancements are still frequent worldwide. The Mediterranean region, a global biodiversity hotspot characterized by a complex geographic history, is home to a substantial portion of its described diversity. Sicily is the region’s largest island and, as ongoing investigations are revealing, it is inhabited by a long-overlooked but highly diverse ant fauna that combines multiple biogeographic influences. We combined qualitative and quantitative morphology of multiple castes with phylogenomic analysis based on ultra-conserved elements (UCEs) to describe four species of Temnothorax endemic to Sicily and the neighboring Maltese Islands (Sicilian Channel). Three of these species, T. marae Alicata, Schifani & Prebus sp. nov., T. poldii Alicata, Schifani & Prebus sp. nov. and T. vivianoi Schifani, Alicata & Prebus sp. nov., are new to science, while a redescription clarifies the identity of T. lagrecai (Baroni Urbani, 1964). These descriptions highlight the current difficulties of delimiting monophyletic Temnothorax species groups based on morphological characters. The intra-insular endemicity patterns we revealed highlight the importance of Mediterranean paleogeography to contemporary ant diversity and distribution in the region.
New species of genus Atractides Koch, 1837 (Acari: Hydrachnidiae, Hygrobatidae) from Qinghai, China
(2022)
The paper deals with five new species of the genus Atractides Koch, 1837 (Acari: Hydrachnidiae, Hygrobatidae) collected from Qinghai Province, P.R. China, Atractides (Atractides) biprojectus Zhang, Li & Guo sp. nov., Atractides (Atractides) smiti Zhang, Li & Guo sp. nov., Atractides (Atractides) menyuanensis Zhang, Li & Guo sp. nov., Atractides (Atractides) longiprojectus Zhang, Li & Guo sp. nov. and Atractides (Atractides) xianmiensis Zhang, Li & Guo sp. nov. All the new species are described and illustrated in detail, and all the type specimens are deposited in the Institute of Entomology, Guizhou University, Guiyang, China (GUGC).
Three new species of Myolepta Newman, 1838 are described from Thailand (M. iota sp. nov.), Laos (M. diaphora sp. nov.) and Indonesia (M. geras sp. nov. from Java), and new records of Myolepta petiolata Thompson, 1971 from Thailand are also provided. Diagnoses, illustrations and known distributional data are given. In addition, the generic affinities and subdivision of Myolepta are discussed based on these newly described taxa.
We describe Loimia davidi sp. nov. (Annelida, Terebellidae) from São Miguel Island (Azores). It resembles Loimia gigantea (Montagu, 1819) (English Channel) in having very large adults, the ventral shield shape and the types of capillary notochaetae (three), while differing in shape and colour of the lateral lappets, branchiae length, the arrangement of segments, ventral shields, uncini and pygidial papillae. Large (> 30 cm long) and small (≈ 5 cm long) specimens of L. davidi sp. nov. show typically interspecific morphological differences while clustering in a single entity after species delimitation analyses of a cytochrome c oxidase I fragment. Therefore, we consider them to belong to a single species and discuss the taxonomic implications of size-dependent morphological differences. Within Loimia, we (1) suggest that large specimens may have been scarcely reported due to their rarity and collecting difficulty, while small specimens may have been reported either as ‘sp.’ or as the ‘cosmopolitan’ Loimia medusa (Savigny, 1822), (2) evaluate the size-related morphological disparity in all described species using a hypervolume analysis, (3) identify possible similar size-dependency in previously described species, (4) summarise the morphological information of all known species of Loimia; and (5) discuss on the four species reported in Europe.
A database of larval host plants for the tortricid tribe Grapholitini (Lepidoptera: Tortricidae: Olethreutinae) is presented, and larval hosts are summarized for each genus. Food plants have been reported for over 400 of the approximately 1,644 described species of Grapholitini. Of the 81 genera currently assigned to the tribe, at least one larval host has been reported for 51. Ninety-seven different plant families have been reported at least once for a species of Grapholitini, with the greatest number of grapholitines recorded from Fabaceae (168 species), followed by Fagaceae (43 species), Pinaceae (43), Sapindaceae (36), Rosaceae (30), Asteraceae (30), Euphorbiaceae (15), Rutaceae (12), Annonaceae (12), Salicaceae (11), and Cupressaceae (11). Thirty-two genera appear to be restricted, or nearly so, to specific host families, but many of these are either monotypic or are represented by exceedingly few records. Extraordinarily, entomophagy is well documented in three genera: Andrioplecta, Coccothera, and Parapammene. Two new combinations are provisionally proposed based on hosts and male genitalia: Andrioplecta magnetica (Meyrick, 1928), new combination, and A. theristis (Meyrick, 1912), new combination, both of which are currently assigned to “Grapholitini unplaced species.”

The tortoise beetle, Cassida sphaerula Boheman, 1854 (Coleoptera: Chrysomelidae: Cassidinae: Cassidini) is endemic to South Africa. Its endemic host, Arctotheca prostrata (Salisb.) Britten (Asteraceae) has been introduced in other countries where it is becoming invasive. Cassida sphaerula could provide a potential biocontrol of Arctotheca weeds as it spends the entire life cycle on this host. An intensive field study, with rearing, photography, and short films of C. sphaerula was conducted in its native habitat to document the life cycle. A checklist of Cassidinae genera in South Africa, along with 19 new host records for Cassidini species in South Africa are presented. Oothecae are simple, with few laminate membranes enclosing fewer than five eggs. There are five larval instars. Larvae and adults feed by making a series of cuts in the ventral cuticle, forming an arc, and they consume the mesophyll as the cuticle is rolled to one side. This creates many ventral craters, thickened on one margin with the rolled cuticle; these ventral craters correspond to ‘windows’ in the dorsal leaf surface where the dorsal cuticle is left intact. This unusual feeding pattern is known in three Cassida species, all in South Africa. Like many tortoise beetles, instar I initiates a feces-only shield on its paired caudal processes (= urogomophi); this construction is retained, along with exuviae, by subsequent instars. The shield construction was studied by film and dissections. This revealed that the columnar or pyramidal shield in this species has an exterior of dry or moist feces that obscures the central nested stack of exuviae, each exuviae compressed onto the caudal processes. Pupae may retain the entire larval shield of exuviae and feces or only the 5th instar exuviae; this behavioral flexibility in pupal shield retention is novel for tortoise beetles. Behaviors of C. sphaerula are discussed in the context of phylogenetic characters that can give evolutionary insights into the genus, tribe, and subfamily.

Current globalization and technological progress has facilitated and increased the international trade of plant products worldwide and has promoted the long-distance movement of immobile sucking pests such as whiteflies attached on plants. Therefore, being able to compile and update information on intercepted insect pests will help to improve the inspection procedures, to detect, identify and mitigate the damage caused by exotic invasive pests. Records of whiteflies (Hemiptera: Aleyrodidae) intercepted on import plants from 2013 to 2021 in the Pest Information System (PIS) database of South Korea were analyzed. A total of 32 species belonging to 19 genera were intercepted on plants imported into South Korea from 20 countries, mostly located in the Oriental region including China. Brief diagnoses, an identification key and photographs of the 32 species intercepted on agricultural commodities and the countries from which they were detected on plants are given to assist in their identification. In addition, this information provides background data and scientific rationale for decisions regarding the management of whiteflies intercepted at the South Korean ports on imported plant products to prevent the introduction and establishment of exotic whiteflies into South Korea.

Lipaphis alliariae Müller (Hemiptera: Aphididae) was identified from specimens collected in Lake County, Ohio, on the invasive garlic mustard, Alliaria petiolata (Bieb.) Cavara & Grande (Brassicaceae). The identification was performed on apterous viviparae using morphological and molecular data. Body color and shape of the cauda discriminated L. alliariae and L. pseudobrassicae Davis. Measurements of morphological characters of both species were similar, but they have distinct characters distinguishing them fromL. erysimi Kaltenbach. Neighbor-joining analysis of cytochrome oxidase 1 (Cox1) barcoding indicated a close relationship of the aphids that feed on Brassicaceae, and the range of pair-wise distances for Cox1 barcoding of these species was 0.3–0.9%.

Following a review of the circumscription of the genus Cladoceras Bremek. (Rubiaceae) in relation to Tarenna Gaertn., the new species Cladoceras rovumense I.Darbysh., J.E.Burrows & Q.Luke sp. nov. is described from the dry forests of the Rovuma Centre of Plant Endemism (CoE) in southeast Tanzania and northeast Mozambique. This species has previously been known as Tarenna sp. 53, following the revision of African Tarenna by Jérôme Degreef. A comparison to Cladoceras subcapitatum (K.Schum. & K.Krause) Bremek., the only other member of this genus as currently circumscribed, is provided. The new species is assessed as Endangered under the criteria of the IUCN Red List. New records for Mozambique of two further Rovuma CoE endemics are recorded: Celosia patentiloba C.C.Towns. (Amaranthaceae) and Cordia fissistyla Vollesen (Boraginaceae), both of which are globally threatened.
The Stachytarpheta longispicata complex is a group of seven accepted infraspecific taxa endemic to the Brazilian Cerrado, defined by its pedicellate flowers with salmon or dark red corollas. Due to the great morphological variation and very brief original descriptions, these taxa have controversial circumscriptions. We evaluated the morphological variation through the morphometric analysis of 11 natural populations in addition to nomenclatural types to assess the current infraspecific circumscriptions and clarify the limits of these taxa. A set of 36 continuous vegetative and reproductive characters was measured for each of the 115 specimens sampled, encompassing the morphological variability in the group and its geographic distribution. A compiled data matrix formed the basis for the multivariate analysis (UPGMA, PCA, and DA). Our results recovered five consistent groups corresponding to the four subspecies, and all three recognised varieties treated in the same morphological group. Quantitative and qualitative characters not previously studied in detail are important to delimit the five groups. A taxonomic rearrangement is proposed for the complex, circumscribing five distinct species: Stachytarpheta brevibracteata, S. longipedicellata, S. longispicata, S. minasensis, and S. ratteri. The taxonomic treatment includes four new combinations and names at new rank, two new synonyms, and one lectotype. Descriptions, an identification key, geographical distribution map, illustrations, and provisional conservation assessments are also provided.
The Cretaceous family Cretapsychidae Wichard, 2021 belongs to the superfamily Sericostomatoidea Stephens, 1836 and is characterized by the five-segmented maxillary palps, with the second segment being the longest and the following three segments becoming successively smaller, and the tibial spur formula 2/2/4. In addition, the wing venation is characterized by apical forks II, III, and V in the forewings and forks I, III, and V in the hindwings. The two newly described species (C. kachini sp. nov. and C. myanmari sp. nov.) extend the genus Cretapsyche Wichard, Neumann, Müller & Wang, 2018 to six extinct species, all of which were found in mid-Cretaceous Burmese amber from Kachin State, Myanmar.
Lycosa Latreille, 1804 (Araneae, Lycosidae) of Israel, with a note on Geolycosa Montgomery, 1904
(2022)
Lycosa (Araneae, Lycosidae) is a wolf spider genus typical of subtropical latitudes in the western Palearctic. Despite being erected over 200 years ago, the taxonomy of Lycosa is still unclear. Many species formerly ascribed to it are currently being moved to other genera, while new species are still being described. The species of Lycosa of the western Mediterranean basin are relatively well known, yet the Levantine region, the easternmost part of the Mediterranean basin, has not received much attention since the early 20th century. Here, we study Lycosa from the southern Levant using morphological, molecular and behavioral characteristics, to delimit the species found in this region. We describe two new species: L. hyraculus sp. nov. and L. gesserit sp. nov. We re-describe the widespread and polymorphic species, Lycosa piochardi Simon, 1876. Lycosa piochardi infraclara Strand, 1913 is synonymized with Lycosa piochardi. By adding novel data to the molecular phylogeny of Lycosa created by Planas et al. (2013) and re-analyzing it, we explore the relationship of the Levantine species to other Mediterranean species of Lycosa. We discuss habitat preferences of the two species of Lycosa. Additionally, we report the burrowing species Geolycosa vultuosa (C.L. Koch, 1838) as a new record to Israel, thus extending the distribution of this species and genus into the Levant.
We describe a new troglophilic species of Filistata, F. betarif sp. nov. , collected from two caves in central Israel, by using light and electron microscopy and by DNA barcoding of the cytochrome c oxidase subunit I (COI) gene. Sequences of this gene show more than 15% of divergence between the new species and its sibling, F. insidiatrix (Forsskål, 1775), which is widely distributed across the Mediterranean and the Middle East. Notwithstanding, the two species are diagnosed only by a minor morphological detail in the embolic keel of the male pedipalp; females of both species are not diagnosable based only on morphology. We also find that samples of F. insidiatrix from different localities have large genetic divergence values (larger than 15% in some cases), but their pedipalps are identical in males; this suggests that F. insidiatrix might hide an additional cryptic diversity. We take this opportunity to provide a dichotomous key for identifying the crevice-weavers (Filistatidae) of Israel and Palestine.
New species of sabellariids (Annelida: Sabellariidae) from the Caribbean Sea and the Gulf of Mexico
(2022)
In the Caribbean Sea and the Gulf of Mexico, 15 species of sabellariids have been described. Since Kirtley’s (1994) worldwide review, at least seven species have not been re-recorded for this region. Therefore, the aims of this contribution were: a) to review the sabellariids held in scientific collections, b) to generate standardized descriptions, and c) to provide taxonomic identification keys for the species of the region. The sabellariids of two Mexican and one US scientific collection were reviewed. Five new species are described: Lygdamis pechi sp. nov. from Veracruz, Gulf of Mexico, Mariansabellaria caribbea sp. nov. from Quintana Roo, Mexico, Phalacrostemma danieli sp. nov. from southwest of Grenada, Tetreres israeli sp. nov. from the Virgin Islands, and T. oscari sp. nov. from Florida. Another morphospecies, Phalacrostemma sp., is characterized by a single incomplete specimen from the Bahamas. Also, new records of Phalacrostemma perkinsi Kirtley, 1994, and P. dorothyae Kirtley, 1994 were made.
Coiled nautiloids of the Tournaisian and early to middle Viséan (Early Carboniferous) have so far only become known from a few regions. Here we describe material from five localities in southern Algeria; these belong to four stratigraphic horizons (two horizons in the late Tournaisian, one horizon near the Tournaisian–Viséan boundary, one horizon in the early to middle Viséan). From these, the new genera Stroborineceras gen. nov. and Trilobitoceras gen. nov. and the following new species are described: Rineceras tenerum sp. nov., Stroborineceras insalahensis gen. et sp. nov., Stroborineceras felis gen. et sp. nov., Stroboceras mane sp. nov., Stroboceras ancilis sp. nov., Vestinautilus angulatus sp. nov., Vestinautilus papilio sp. nov., Vestinautilus inflexus sp. nov., Vestinautilus bicristatus sp. nov., Trilobitoceras peculiaris gen. et sp. nov., Aphelaeceras azzelmattiense sp. nov., Maccoyoceras saharensis sp. nov., Maccoyoceras habadraense sp. nov. and Maccoyoceras concavum sp. nov.
Five new species of the genus Andes Stål, 1866 from China (Hemiptera, Fulgoromorpha, Cixiidae)
(2022)
Five new species of the genus Andes Stål, 1866, A. balteiformis Wang, Zhi & Chen sp. nov., A. bifidus Wang, Zhi & Chen sp. nov., A. furcutus Wang, Zhang & Chen sp. nov., A. latanalus Wang & Chen sp. nov. and A. pallidus Wang & Chen sp. nov. from China, are described and illustrated. A key to the species of Andes in China is provided.
A new species of the myrmeleontine antlion genus Baliga Navás, 1912 (Neuroptera: Myrmeleontidae), Baliga kashmirensis sp. nov., from Azad Kashmir and Khyber Pakhtunkhwa Province of Pakistan is described and illustrated, representing the first record of Baliga from Pakistan. Three species of Myrmeleon Linnaeus, 1767 are re-described: M. hyalinus hyalinus Olivier, 1811, M. tenuipennis Rambur, 1842, and M. trivialis Gerstaecker, 1885. Myrmeleon bimaculatus Yang, 1999 syn. nov. originally described from China is considered to be a junior synonym of Myrmeleon tenuipennis Rambur, 1842. In addition, an annotated catalogue of all species of Myrmeleon known from Pakistan along with their distribution map, taxonomical notes and updated identification key to known genera and species are provided.
This review considers a fascinating, from a zoogeographical viewpoint, group of closely related species: Melitaea lutko Evans, 1932, M. timandra Coutsis & van Oorschot, 2014, M. mimetica Higgins, 1940 stat. rev. and M. shahvarica sp. nov. It is a taxonomical and geographical review of these species, and data on the biology of M. shahvarica sp. nov. and nominate subspecies of M. timandra are discussed. A new species, M. shahvarica sp. nov. from Shahvar Mt. (Iran), and a new subspecies, M. timandra binaludica subsp. nov. from Kuh-e-Binalud Mts (Iran), are described. The specific structure of the group given in previous publications is critically evaluated. Hypotheses about a possible phylogenesis of the study group are provided.
The genus Cheilosia (Diptera: Syrphidae: Rhingiini) of Nepal is reviewed. We recorded 37 species of Cheilosia, of which 29 species are described here. Twenty-six of the new species are classified to a subgenus: Cheilosia (Cheilosia) angusta sp. nov., C. (C.) falcata sp. nov., C. (C.) hauseri sp. nov., C. (C.) maculata sp. nov., C. (C.) pica sp. nov., C. (C.) pilivena sp. nov., C. (C.) spinosa sp. nov., C. (C.) spuria sp. nov., C. (C.) weiperti sp. nov., C. (Montanocheila) albipicta sp. nov., C. (M.) alpha sp. nov., C. (M.) brevimontana sp. nov., C. (M.) gilva sp. nov., C. (M.) minuscula sp. nov., C. (M.) nigella sp. nov., C. (M.) pernigra sp. nov., C. (M.) picta sp. nov., C. (Floccocheila) collis sp. nov., C. (F.) crassata sp. nov., C. (F.) illustratoides sp. nov., C. (F.) indistincta sp. nov., C. (F.) leucozonoides sp. nov., C. (F.) vellea sp. nov., C. (Eucartosyrphus) procera sp. nov., C. (Pollinocheila) rava sp. nov., and C. (Taeniochilosia) nepalensis sp. nov. The remaining three new species, C. flavigena sp. nov., C. insolita sp. nov., and C. versa sp. nov., are described based on a female only, and are thus not classified to a subgenus. The subgenus Taeniochilosia Oldenberg, 1916 is here re-defined to also include species with a pilose eye in combination with the previously defined characters. Cheilosia nigriventris Barkalov & Cheng, 2004 is herewith placed as junior synonym of Cheilosia erratica Barkalov & Peck, 1997, and the description of the female sex is provided. We provide digital photographs and line drawings to illustrate morphological details of all species, and an identification key to the subgenera and to the species recorded for Nepal. We explored the infrageneric classification of some Nepalese species new to science for which molecular work was possible using mtDNA COI barcode sequences. A maximum likelihood analysis of the assembled COI barcode dataset with multiple representatives of the most speciose Palearctic subgenera of Cheilosia resolved the included seven taxa from Nepal within subgenera Cheilosia s. str. and Montanocheila Barkalov, 2002. The large number of new species of this study highlights the still prevailing incomplete knowledge of this speciose genus in the montane regions of the Palearctic and Oriental realms.
Freshwater sponges constitute an overlooked part of the freshwater fauna in Sweden and there has been no recent systematic survey. Hitherto three species have been found in Sweden: Spongilla lacustris (Linnaeus, 1759), Ephydatia fluviatilis (Linnaeus, 1759) and E. muelleri (Lieberkühn, 1856). Neighbouring countries (Norway, Denmark, Estonia) harbour at least one additional species. We present a study on freshwater sponge diversity and distribution in the southern half of Sweden. We hypothesized dispersal within catchments to be less constrained than between, even at shorter intercatchment than intracatchment distances, and, as result, genetic distances being greater between than within catchments. We collected and identified freshwater sponges from 34 sites, using morphological and molecular data (coxI, 28S rRNA gene). We can report the presence of Eunapius fragilis (Leidy, 1851) in Sweden for the first time, and that S. lacustris is the most abundant and widely distributed freshwater sponge in Sweden. Genetic markers were tested on S. lacustris individuals for a phylogeographic study. From the 47 primers (24 markers), one pair presented successful amplification and enough variation for phylogeographic studies – i56, an intron located in a conserved gene. Seven different variants were found in the sampling area, but no clear population structure was observed.
Eight new Neotropical species of Dexosarcophaga Townsend, 1917 are described, five from Brazil, Dexosarcophaga phoenix sp. nov., Dexosarcophaga jandainae sp. nov., Dexosarcophaga patiuorum sp. nov., Dexosarcophaga petra sp. nov., and Dexosarcophaga sphaera sp. nov., one from Costa Rica, Dexosarcophaga limon sp. nov., one from Ecuador, Dexosarcophaga napo sp. nov., and one from Colombia, Dexosarcophaga pallida sp. nov. Male and female morphology is documented with photographs and illustrations, including details of the male terminalia for all new species and female terminalia of Dexosarcophaga phoenix sp. nov. and Dexosarcophaga sphaera sp. nov. With the addition of these new species, 58 species of Dexosarcophaga are now known, with records from the American continent spanning from the southern United States to northern Argentina.
Baldellia ranunculoides (Alismataceae) was thought to be first observed in Cyprus at the southern tip of the island in 1991. However, an older specimen collected near Syrianochori in 1952 has hitherto been overlooked. It is recommended to expand the search for this "Regionally Extinct (RE)" water plant to the northwest of Cyprus.
Chromosome counts of Lactuca viminea from Cyprus revealed the diploid number 2n = 18, which confirms results from other parts of its distribution range. Cultivation of plants corroborated the existence of two habit forms but assignment of Cypriot material to infraspecific taxa still seems to be premature.
Various noteworthy records of flowering plants in Cyprus (1996–2019) and some status clarifications
(2020)
This paper deals with specimen-based records of 33 taxa, most of them having a scattered occurrence or restricted distribution range in Cyprus. The following taxa are new to Cyprus or have been documented by specimens for the first time: Artemisia verlotiorum, Atriplex suberecta, Cardamine occulta, Catharanthus roseus, Erigeron sumatrensis, Euphorbia graminea and Solanum lycopersicum. The recently found Cenchrus setaceus, already problematic as invasive outside Cyprus, seems to spread quickly on the island and should be given particular consideration.
Solenopsis annua, formerly thought to be a Greek endemic, is recorded in Cyprus for the first time. A morphological description and information on its taxonomy, distribution and habitat, as well as its floristic status are provided. It is recommended to treat it at species rank following the currently prevailing trend of a micro-species concept in Solenopsis. Regarding its future Red Data Book status in Cyprus it should be characterised as "Endangered".
New noteworthy records of flowering plants in Cyprus (2019–2021) and some status clarifications
(2022)
This paper deals with specimen-based records of 20 taxa, the majority of which are alien species in Cyprus. The following taxa are new to Cyprus or have been documented by specimens for the first time: Allium tuberosum, Amaranthus emarginatus subsp. pseudogracilis, A. powellii, Commelina communis, Cyperus alternifolius subsp. flabelliformis, Helianthus annuus, Lantana camara, Leucaena leucocephala subsp. leucocephala, Phoenix dactylifera, Urochloa ramosa, Washingtonia filifera and Zea mays. Namely Leucaena leucocephala should be given particular consideration because it may soon become a problematic invasive.
Hornschuchia (Annonaceae), an endemic and threatened genus from the Brazilian Atlantic Forest
(2022)
The South American Atlantic Forest is a biodiversity hotspot, and a relevant area for conservation due to its high level of endemism and great loss of habitat. One of its endemic taxa is the genus Hornschuchia (Annonaceae), including 12 species that occur from the State of Rio de Janeiro to Pernambuco in Brazil. The last taxonomic treatment of Hornschuchia was carried out 27 years ago. Since that time, two new species have been described and new specimens of known species have been collected, expanding our knowledge about the morphology and distribution of the genus. Hornschuchia, as an endemic genus in a threatened environment, deserves special attention. For this reason, we updated the taxonomic treatment of Hornschuchia, including the recently described species in the key, preparing illustrations, updating the descriptions of the species, clarifying and correcting information regarding the historical and type collections, providing preliminary conservation statuses, and analyzing patterns of endemism and richness for the genus. One species is preliminarily assessed as Critically Endangered, nine are Endangered, one is Vulnerable and one is of Least Concern. The coast of Bahia is a priority place for conservation for Hornschuchia as its center of species diversity.
The present study aims to resolve the taxonomic confusion involving several taxa within Mycetophagidae Leach, 1815, originating from the introduction of the genus Atritomus Reitter, 1877, and then by its subsequent controversial interpretation. A detailed overview of the taxonomic and nomenclatural history of the taxa previously linked to Atritomus is provided. The authors propose the introduction of Stereophilus Biscaccianti, Audisio & Esser gen. nov. for Atritomus filicornis Reitter, 1887, and the restoration of Entoxylon Ancey, 1869 at the genus rank, together with some rectifications regarding the authorship and the date of publication of both Entoxylon and its type species, E. abeillei Ancey, 1869. Moreover, the Ethiopian species Atritomus vicinus Grouvelle, 1908 is herein transferred to the genus Typhaeola Ganglbauer, 1899 based on the examination of the holotype. The following new combinations are proposed: Entoxylon baudii (Seidlitz, 1889) comb. nov. (from Esarcus Reiche, 1864), Entoxylon besucheti (Dajoz, 1964) comb. nov. (from Esarcus subg. Entoxylon), Entoxylon franzi (Dajoz, 1964) comb. nov. (from Esarcus subg. Entoxylon), Entoxylon inexpectatus (Dajoz, 1964) comb. nov. (from Esarcus subg. Entoxylon), Entoxylon martini (Reitter, 1887) comb. nov. (from Esarcus), Stereophilus filicornis (Reitter, 1887) gen. et comb. nov. (from Atritomus), Typhaeola vicina (Grouvelle, 1908) comb. nov. (from Atritomus).
Ranunculus sect. Auricomus umfasst außer den heimischen Vertretern der R. auricomus-Gruppe und R. pygmaeus eine Reihe weiterer, temperat bis arktisch verbreiteter Arten in Nordamerika und in den Zentralasiatischen Gebirgen. R. sect. Auricomus ist daher nicht mit der/dem vorwiegend apomiktischen R. auricomus-Gruppe / -Komplex (R. auricomus agg.) gleichzusetzen, sondern hat einen größeren taxonomischen Umfang.
Die Ranunculus auricomus-Gruppe umfasst im Gebiet der Flora von Zentraleuropa zwei der insgesamt fünf sexuellen Arten des Komplexes sowie eine Reihe von apomiktischen, hybridogenen Taxa. Diese beiden diploiden bis tetraploiden Arten (R. cassubicifolius und R. notabilis) repräsentieren zwei unterschiedliche Morphotypen, die früher als Artengruppen (R. cassubicus L. s.l. und R. auricomus L. s.l.) unterschieden und von manchen Autoren als Subsektionen innerhalb Ranunculus sect. Auricomus klassifiziert oder auch als informelle Artengruppen (Großgruppen, Sammelgruppen, Aggregate, Komplexe) behandelt wurden. Jedoch haben neuere genetische Untersuchungen gezeigt, dass diese morphologisch definierten Gruppen keine Abstammungsgemeinschaften darstellen. Sie werden daher hier nicht aufrechterhalten. Die in manchen Publikationen auch als gleichwertig eingestuften und unterschiedenen Artengruppen des R. fallax und des R. monophyllus werden hier ebenfalls nicht berücksichtigt. Umfassende phylogenomische Untersuchungen zeigen, dass in Europa drei große, unscharf getrennte genetische Cluster vorliegen, die eine West-Ost-Differenzierung zeigen.
Habenaria karstica J.A.N.Bat. sp. nov., a new species from limestone outcrops (i.e., karst) in the State of Minas Gerais, Brazil, is described. The new species is ecologically very distinct since it is the only Neotropical species of the genus that grows on limestone outcrops under full sun, associated with mat-forming saxicolous plants. It is morphologically similar to species of the Habenaria repens complex, and separation is only possible through a combination of morphological characters. Bayesian and parsimony phylogenetic analyses based on nuclear (rDNA ITS, ETS) and plastid (matK-trnK, rps16-trnK) DNA markers revealed that H. karstica belongs to H. sect. Spathaceae. The new species, however, differs in floral morphology from the other species in this clade. A survey of the literature and public plants datasets revealed 122 species and 58 genera of Orchidaceae in karsts of Brazil. Although small compared to the family’s diversity in the country, Orchidaceae is among the families with the highest number of species in some karst localities. Our results indicate that approximately 97% of Orchidaceae found in karsts of Brazil is not limited to limestone outcrops areas, and that species composition of each locality is primarily determined by the regional flora and the biome in which it is located.
A confusingly labeled water-milfoil of obscure status, known only in cultivation, is here formally described as a new species, Myriophyllum rubricaule Valk. & Duist. sp. nov. This species has fully replaced M. aquaticum in the horticultural trade in Europe since the addition of M. aquaticum to the list of invasive alien species of Union concern (EU regulation no. 1143/2014) in 2016. This manuscript provides a morphological description of M. rubricaule sp. nov., and its distinction from M. aquaticum is further supported by molecular data (chloroplast and nuclear loci).
Two species of stick insect with a distinctive morphology, Candovia evoneobertii (Zompro & Adis, 2001) and Echetlus fulgens Zompro, 2004, were considered to be native to Australia and introduced into Brazil. However, Heteronemia dubia (Caudell, 1904) and Heteronemia fragilis (Brunner von Wattenwyl, 1907), both described more than a hundred years ago from South America, exhibit striking similarities with the two purportedly introduced species and are found to be conspecific with C. evoneobertii. Careful analysis of the literature and specimens revealed that these species belong to the Neotropical tribe Diapheromerini (Diapheromeridae) and represent a new genus, Arumatia Ghirotto gen. nov. We therefore propose Arumatia fulgens (Zompro, 2004) gen. et comb. nov. and Arumatia dubia (Caudell, 1904) gen. et comb. nov. We further redescribe A. dubia (Caudell, 1904) gen. et comb. nov. based on several specimens and synonymize Heteronemia fragilis syn. nov. and Candovia evoneobertii syn. nov. under it. Additionally, five new Brazilian species are described: Arumatia diamante Ghirotto gen. et sp. nov. from Abaíra, Bahia; Arumatia aramatia Ghirotto gen. et sp. nov. from Porto Nacional, Tocantins; Arumatia motenata Ghirotto gen. et sp. nov. from Serra do Cipó, Minas Gerais; Arumatia crassicercata Ghirotto, Crispino & Engelking gen. et sp. nov. from Alto Paraíso de Goiás, Goiás; and Arumatia anyami Ghirotto, Crispino & Neves gen. et sp. nov. from Costa Marques, Rondônia. Species of Arumatia gen. nov. occur mostly in the Cerrado domain, and represent the first Diapheromeridae recorded in this area. Most species are known exclusively from females with only A. aramatia gen. et sp. nov. and A. motenata gen. et sp. nov. known from both sexes. Adult and egg morphology are described and illustrated in detail for all species, as well as the nymph stages for A. dubia. Biological observations are presented, including parthenogeny in A. dubia and one of the few detailed accounts of sexual behaviour in Euphasmatodea (for A. motenata gen. et sp. nov.). Finally, a species of Diapheromerini described in error from Brazil, Diapheromera armata Piza, 1973, is synonymized under the North American Megaphasma denticrus (Stål, 1875) (syn. nov.).
A new species of Epeolus Latreille, 1802 (Hymenoptera: Apidae)—E. emiliae Onuferko and Sheffield, new species—is described from North America west of the Great Plains. It is morphologically most similar to Epeolus autumnalis Robertson, 1902, a species known exclusively from east of the Rocky Mountains. DNA barcode sequences from representatives of E. autumnalis and E. emiliae share a barcode index number (i.e., BIN: BOLD:AAF2361), but the two species exhibit marked and consistent differences in integument coloration and the patterns of pubescence on the metasoma, and their distributional ranges, based on known specimens, show no overlap. This discovery increases the number of species of Epeolus confirmed in Canada to 14, and North America north of Mexico to 44. Modifications to existing identification keys to Canadian and all North American species of Epeolus are provided, as well as a differential diagnosis, to enable the identification of E. emiliae. Additionally, three new provincial records are reported for species of Epeolus occurring in Canada: E. interruptus Robertson, 1900 from Alberta and Quebec and E. scutellaris Say, 1824 from Saskatchewan.

Tomoxia bucephala A. Costa (Coleoptera: Mordellidae), a Palearctic tumbling flower beetle native to Europe, Asia, and northernmost Africa, is now known from North America. The first known occurrences were in 2015 in Essex and Union counties, New Jersey, U.S.A. and in 2019 in Passaic County, New Jersey, all in the New York City metropolitan area. An additional collection documents the species in 2016 from Allegheny County, Pennsylvania, in the Pittsburgh metropolitan area. The multiple occurrences, the large distance between those in New Jersey and Pennsylvania, and multiple detections in natural areas indicate T. bucephala is established in North America and apparently invasive. Several morphological features differentiate T. bucephala from the two congeners native to North America, T. inclusa LeConte and T. lineella LeConte, especially coloration patterns of elytral and pronotal vestiture, and coloration of antennae and front legs. This is the first report of a non-native mordellid species established in North America. Tomoxia bucephala does not appear to pose a significant direct economic threat in North America since it feeds in decaying trees. However, T. bucephala occurrences are within the geographic ranges of T. inclusa and T. lineella, and the biology of T. bucephala is similar to these other Tomoxia species. Thus, T. bucephala likely will expand its range within North America, with probable ecological impact on communities of native saproxylic beetles, especially T. lineella and T. inclusa.

A new paedogenetic midge (Diptera: Cecidomyiidae: Winnertziinae: Heteropezini) from O‘ahu Island, Hawai‘i, Neostenoptera hawaiiensis Plakidas, Nguyen, and Ferro, new species, is described and illustrated. A key to all species in the genus is provided. Specimens were emergent from deadwood gathered at Waimea Arboretum and Botanical Garden. Neostenoptera appalachiensis Plakidas and Ferro were collected from the same set of samples in Hawai‘i, and additional specimens are reported from Georgia and South Carolina, three new state records. The discovery of two paedogenetic midges in Hawai‘i poses a unique set of questions as to their possible mode of arrival on an island ecosystem. We briefly address the possibility that both species are simply “hitchhikers” that went undetected at ports of entry.

New information is presented for Neotropical Cerambycidae (Coleoptera). Dolichestola vittipennis Breuning, 1948 is synonymized with D. annulicornis Breuning, 1942, and the species is newly recorded from the Brazilian state of São Paulo. Dolichestola densepunctata Breuning, 1942 is newly recorded from Venezuela and Brazil, and the difference between it and D. annulicornis is reported. Mecas skillmani Santos-Silva and Androw, new species, is described from Mexico (Jalisco). Pannychella callicera (Bates, 1881) is illustrated, and notes on the genus and species are provided. Pannychis Thomson, 1864 is considered a genus different from Mecas LeConte, 1852, and notes on the genus and P. sericea Thomson, 1864, new combination, are given; therefore, Mecas has no subgenera. Pannychina Gilmour, 1962 is synonymized with Dylobolus Thomson, 1868, and Pannychina atripennis (Bates, 1885) is synonymized with Dylobolus rotundicollis Thomson, 1868.

Five species of Cautethia Grote (Lepidoptera: Sphingidae) occur in the Lucayan (Bahamas) Archipelago, three of which are new to science. Cautethia simoni Miller, Matthews, and Gott, new species, is described and illustrated from Mayaguana Island, Bahamas, and Providenciales and Grand Turk of the Turks and Caicos Islands. Cautethia gossi Miller, Matthews, and Gott, new species, is described and illustrated from Great Inagua, Bahamas. Cautethia geraceorum Miller, Matthews, and Gott, new species, is described from San Salvador Island. Diagnoses are provided and new island records are reported for the two previously described Bahamas species, Cautethia grotei Edwards and Cautethia exuma McCabe. A taxonomic key based primarily on genitalia is provided for males and known females of the ten described species occurring in the West Indies. COI barcodes were obtained from representative Bahamas specimens and analyzed along with existing barcodes.

During mycological surveys of different areas of Punjab, Pakistan, we collected a new species from the genus Candolleomyces. This is the first report of any species of this genus from Pakistan. Candolleomyces asiaticus M.Asif, A.Izhar, Niazi & Khalid sp. nov. is characterized by ellipsoid to oblong-ellipsoid (8.2 × 5 µm) basidiospores with indistinct germ pores, lageniform to utriform cheilocystidia without adhering deposits at the apices, absence of pleuro-, pileo- and caulocystidia, pileipellis with spherical, subglobose to columnar cells, and presence of clamp connections. The morpho-anatomical and molecular phylogenetic analysis of nrITS revealed its distinct phylogenetic position, further supporting the recognition of a new species.
Antiochtha is a genus of the family Lecithoceridae characterized by the forewing with veins M2 and M3 coincident, the hindwing with vein M2 absent, and the male genitalia with the valva narrowed from base to apex. The genus comprises 23 species and is mainly distributed in the Oriental Region. In this paper, we describe three new species: Antiochtha erromera sp. nov., A. hainanensis sp. nov. and A. miniscula sp. nov., and propose a new synonym, A. rotunda Zhu & Li, 2009 syn. nov., of A. jianfengensis Zhu & Li, 2009. Antiochtha semialis Park, 2002 is newly recorded in China and its female is described for the first time.
New species in Anatoma Woodward, 1859 (Anatomidae, Vetigastropoda) are found in abyssal hydrothermal vent field habitats on the oceanic plate margins in the Indian Ocean. Six species are identified using molecular sequence analyses of which four species are described as new based on their morphological characters: Anatoma discapex sp. nov., Anatoma declivis sp. nov., Anatoma laevapex sp. nov. and Anatoma paucisculpta sp. nov. Inadequate material was available for a morphological description of the other two species with genetic identification, but it is likely that all six species are new to science and endemic to the Indian Ocean. The northern Central Indian Ridge localities are dominated by Anatoma declivis sp. nov.; its closest relative is Anatoma discapex sp. nov. which occurs in the central area near the Rodriguez Triple Junction. Anatoma laevapex sp. nov. and Anatoma paucisculpta sp. nov. as well as a fifth undescribed species are mainly found on the Southeast Indian Ridge.
The present study examines whether the chaetotaxy of the costal vein in the calyptrate families Fanniidae and Muscidae deserves more attention in phylogenetic and taxonomic contexts. An overview of the macrotrichia and their arrangement on wing vein C is given. Special attention is given to the presence/absence of ventral and dorsal setulae on the costal sectors CS1‒3. This is described as one variable character (A) with nine states (A0‒A8). Specimens of both sexes (when possible) of each species belonging to 4 of a total of 5 fanniid genera and 115 of a total of 179 muscid genus-group taxa were examined and scored for character A. It was found that the presumed ancestral state of character A differs between the two families. It is further shown that the main transformational trend in character A in Muscidae has been bi-directional, leading either to the loss of ventral setulae or the gain of dorsal setulae. The utility of character A in the Fanniidae and Muscidae is many-sided and involves taxa ranging from species to family. It is concluded that character A and other aspects of costal chaetotaxy deserve more attention in morphology-based studies of calyptrate flies.
Three new species of the genus Superciliaris Meng, Qin & Wang, 2020 are described from southern Vietnam, Malaysia (northern Borneo), and Indonesia (northern Sulawesi). The genus is recorded for the first time from mainland Asia and Sunda Archipelago. A key to species of Superciliaris is given. The relationships of the species are discussed.
The discovery of a new species of the genus Canthocamptus, C. waldemarschneideri sp. nov., in northern Siberia prompted a taxonomic analysis of this genus. In this work, on the basis of cladistic analysis, we show that the genus is not monophyletic. Based on differences in the structure of the endopods on the second pair of male swimming legs, fifth legs of males and females, and caudal rami, we conclude that the Canthocamptus mirabilis species group is a separate genus, Kikuchicamptus gen. nov. Additionally, two species are transferred to the genus Attheyella, and one species, Canthocamptus gibba, is synonymized. The subgenera Canthocamptus (Baikalocamptus) and Canthocamptus (Canthocamptus) are also synonymized. The new species, Canthocamptus waldemarschneideri sp. nov., is most closely related to the American Canthocamptus assimilis Kiefer, 1931 and differs from it in the ornamentation of the abdominal somites and the shape of the caudal setae.
Two new species of subgenus Heterophyllidiae subsection Cyanoxanthinae, Russula fusiformata Y.Song sp. nov. and R. purpureorosea Y.Song sp. nov., collected from the Dinghushan Biosphere Reserve (DHSBR), are described based on both morphology and a phylogenetic analysis of the internal transcribed spacer (ITS), further increasing Heterophyllidiae species diversity in the area. Differences between the two new species and related taxa are analyzed. The other 17 reported species of Russula subgenus Heterophyllidiae that have been collected from DHSBR during mushroom explorations since 2014 are also summarized. The dominant species and the ecological distribution of all 19 species are briefly discussed, and most species are presented in macrofungal plates.
During the Census of Marine Life Polarstern ANDEEP I-III and Meteor M79/1 DIVA-3 expeditions, autonomous baited trap systems were employed to sample the mobile, necrophagous amphipods from abyssal depths. Within DIVA-3 (July 10–August 26 2009), a free-fall baited trap was used successfully at three stations in the southwest Atlantic, once in the Argentine Basin and twice in the Brazilian Basin. A total of twenty-one stations were sampled by baited traps during the ANDEEP I-III (2002, 2005) cruises in the Southern Ocean. Trap sets recovered large numbers of scavenging lysianassoid and alicelloid amphipods, including specimens of the widespread and commonly considered cosmopolitan uristid species Abyssorchomene abyssorum (Stebbing, 1888). During examinations of these and other North Atlantic collections of A. abyssorum, two similar new species A. patriciae sp. nov. and A. shannonae sp. nov. were discovered. Important morphological characters which differentiate the two new species from their congeners are found in the shape of the head lobe, coxa 1, gnathopod 2, coxa 5, pereopod 7 basis and uropod 3 rami length. The new species are fully figured and an identification key is provided. Abyssorchomene abyssorum is redescribed and for the first time, the female is fully described and illustrated from new material. The Southern Ocean endemic A. scotianensis (Andres, 1983) is also described and illustrated from new collections to complement the original description.
Taxonomy of fourteen very little known species of Nodosariinae Ehrenberg, 1838 in Icelandic waters is revised. Knowledge of these species in the North Atlantic relies mainly on studies in the late 19th and early 20th centuries, using large volume samplers. Later studies have emphasized quantitative samples of a few cm3 where the Nodosariinae are very rare. This study analysed 879 dredging samples where Nodosariinae occurred in 492 samples, comprising 7598 specimens of about 415 000 of all picked foraminifera. Ordination analysis of species distributions reflects prominent temperature and salinity differences that exist in the sampling area (753 000 km2) north and south of the Greenland-Scotland Ridge (GSR). Eight species are restricted to southern temperate waters (> 2°C): Dentalina mutabilis (Costa, 1855), Dentalina antarctica Parr, 1950, Dentalina antennula d’Orbigny, 1846, Dentalina filiformis (d’Orbigny, 1826), Grigelis pyrula (d’Orbigny, 1826), Grigelis guttifera (d’Orbigny, 1846) comb. nov., Grigelis semirugosus ? (d’Orbigny, 1846) and Nodosaria subsoluta Cushman, 1923. Four species (Nodosaria haliensis Eiland & Guðmundsson, 2004, Nodosaria incerta Neugeboren, 1856, Dentalina elegans d’Orbigny, 1846 and Dentalina frobisherensis Loeblich & Tappan, 1953) occur mainly north of Iceland. Two species, Dentalina obliqua (Linnaeus, 1758) and Pseudonodosaria subannulata (Cushman, 1923), have wide tolerance ranges for physical variables.
The genus Drymeia Meigen, 1826 (Diptera: Muscidae) in Kyrgyzstan: new records and new species
(2022)
The muscid genus Drymeia Meigen, 1826 in Kyrgyzstan has been studied. One new species is described: Drymeia ziegleri sp. nov. An annotated checklist and keys for each sex of the six named species of Kyrgyzstan Drymeia are provided. Five species are newly recorded from Kyrgyzstan. An image of the new species is given.
This paper is devoted to the fauna of Quedius Stephens, 1829 of Middle Asia. It provides descriptions of two species new to science Quedius (Distichalius) gissaricus sp. nov. from Tajikistan and Q. (Raphirus) viator sp. nov. from Kyrgyzstan. Two more species are reported as potentially new to science, but not formally described: Q. (Microsaurus) sp. from the mutilatus group from Tarbagatay Mountains because it is known only from damaged specimens; Q. (Distichalius) sp. aff. gissaricus, known from a single male found sympatrically with Q. (D.) gissaricus sp. nov., remains undescribed because of the possibility of teratology. Earlier records of Q. umbrinus from Middle Asia are considered doubtful or assigned to Q. pseudoumbrinus. Taxonomic notes on the identity of that species as well as Q. cohaesus and Q. fulvicollis in Middle Asia are provided. Among new distribution records summarized for several species, Q. (Velleius) dilatatus, Q. (Microsaurus) tenellus and Q. (Raphirus) jenisseensis are recorded from the territory of Middle Asia for the first time.
In the present study, we used an integrative taxonomy approach to redescribe a population of Echiniscus quadrispinosus quadrispinosus Richters, 1902 from the neotype locality in the Taunus Mountain Range (Germany). We found clear differences in the chaetotaxy formula between the life stages of E. q. quadrispinosus. The body appendages B are, in general, absent in juveniles. Moreover, in larvae all body lateral appendages, except for E, are absent. We also obtained DNA sequences of 18S rRNA, 28S rRNA, ITS-2, and COI of E. q. quadrispinosus from the neotype locality and three Norwegian populations. Comparison with the sequences available in GenBank showed low genetic differences between the neotypic population and specimens from other localities. Therefore, we decided to establish our specimens from Taunus Mountain Range as neotype and paraneotypes of E. q. quadrispinosus. We also discussed and amended the taxonomic status of three subspecies E. q. brachyspinosus Bartoš, 1934, E. q. cribrosus Murray, 1907 and E. q. fissispinosus Murray, 1907 and established them as junior synonyms of E. q. quadrispinosus. Finally, we also confirmed E. lichenorum Maucci, 1983 as a valid species, clearly different from E. q. quadrispinosus.
The monotypic ant genus Igaponera gen. nov. is proposed to include its type species I. curiosa (Mackay & Mackay, 2010). Igaponera gen. nov. is described and phylogenetically compared with other ponerine genera based on external morphology. The type species is known from a single gyne originally described in the genus Pachycondyla Smith, 1858. Igaponera curiosa is easily diagnosed by: costate sculpture on head, mesosoma, and petiole; short, robust, triangular mandibles with blunt apex; relatively large eyes set at mid-length on sides of head; lack of stridulitrum; and presence of distinct but relatively small arolia. Putative apomorphies of the new genus are: cuticular flange concealing metapleural gland opening; vertically standing hypostomal tooth with recessed base; stout mandibular shape with blunt apex; absence of stout spine-like setae on meso- and metatibial apices. Our phylogenetic results based on morphology suggest that Neoponera Emery, 1901 and Pachycondyla are the closest lineages to Igaponera, which shows intermediate characteristics as compared to those genera. The genus is apparently arboreal, known only from a seasonally flooded Igapó forest near Manaus, Brazil. Despite the collection site being frequented by researchers, no other specimens of this genus have been collected in over 40 years prior to this study.
Tardigrades reports from British Columbia (Canada) trace back to 1908 and numerous species have been recorded from this region, despite the relatively few published sampling studies. We describe by integrative taxonomy (light microscopy morphology, morphometrics, and DNA sequencing) a new tardigrade species, Sisubiotus hakaiensis sp. nov. from the British Columbia central coast. The new species has been found in moss collected from a vertical rock outcrop near the Hakai Institute Calvert Island Field Station. Sisubiotus hakaiensis sp. nov. differs from all the other known species in the genus by the presence of a labyrinthine layer inside the egg process walls, whereas no consistent differences in the animals were found. This unique egg characteristic therefore required the amendment of the Sisubiotus generic diagnosis to account for the presence of the labyrinthine layer inside the egg process walls.
Psychodid specimens from one of the world’s biodiversity hotspots – the Caucasus region – were sorted from samples collected during field work in 2019. Pneumia fuehzulii sp. nov. (from two localities in Azerbaijan) and Thornburghiella salihi sp. nov. (from one locality in Azerbaijan and four sites in Georgia) are described from this material. Differential diagnoses are given and some morphological characters illustrated. Sijaricia Krek, 1999, syn. nov. of Thornburghiella Vaillant, 1982 is proposed and T. erinacea (Krek, 1971) comb. nov. from Ulomyia Walker, 1856 is suggested.
The ammonoids of the suborder Gephuroceratina from the Roteisenstein (Red Ironstone) Formation of the area around Dillenburg (eastern Rhenish Mountains) are revised, mainly based on historical collections stored in the Museum für Naturkunde, Berlin. The new species Ponticeras materni sp. nov. is described and the species Pseudoprobeloceras pernai (Wedekind, 1918), Pseudoprobeloceras applanatum (Wedekind, 1918), Ponticeras aequabile (Beyrich, 1837), Darkaoceras galeatum (Matern, 1931), Taouzites acutus (Matern, 1931), Koenenites lamellosus (Sandberger & Sandberger, 1851), Acanthoclymenia forcipifera (Sandberger & Sandberger, 1851) and Acanthoclymenia planorbis (Sandberger & Sandberger, 1851) are revised. The stratigraphic distribution of the genera is discussed; they are assigned to three assemblages: (1) Pseudoprobeloceras pernai Zone (latest Givetian; genera Pseudoprobeloceras, Ponticeras, Darkaoceras and Taouzites), (2) Koenenites lamellosus Zone (early Frasnian, containing Koenenites lamellosus and Acanthoclymenia forcipifera) and (3) Mesobeloceras kayseri Zone (middle Frasnian, containing Acanthoclymenia planorbis).
Two new species of the family Nemouridae of the genus Indonemoura Baumann, 1975, Indonemoura yingjiangensis Bai & Qian sp. nov. and Indonemoura longihamata Bai & Qian sp. nov. are described from Yunnan Province, southwest of China. The morphological characteristics of the two new species are compared to related taxa.
The genus Neostasina Rheims & Alayón is revisited. New material is examined, resulting in the description of seven new species: N. aceitillar sp. nov. (♀), N. bani sp. nov. (♂♀), N. demaco sp. nov. (♀) from Dominican Republic, N. juanita sp. nov. (♀), N. paraiso sp. nov. (♂♀), N. toronegro sp. nov. (♀) from Puerto Rico, and N. maisi sp. nov. (♂♀) from Cuba. New distribution records are given for N. amalie, N. cachote, N. guanaboa, N. iberia, N. saetosa, N. siempreverde and N. turquino. In addition, an updated identification key and updated distribution maps for all species of the genus are provided.
The kinorhynch fauna from Portugal has been explored, yielding a new species of the genus Setaphyes (Kinorhyncha: Allomalorhagida). This is the first description of an allomalorhagid species from Portugal. Specimens of the new species were collected at a subtidal muddy beach in Alvor, a village located in the southernmost region of Portugal. Setaphyes algarvensis sp. nov. may be distinguished from its congeners by a unique arrangement of the setae: paired paradorsal setae on segments 2–7 and 9, paradorsal seta on segment 8 unpaired, laterodorsal setae on segments 2–3 and 6–9 in males and 2–9 in females, paralateral setae on segment 1, lateroventral setae on segments 2–10 (two pairs on segment 5), ventrolateral setae on segment 1 in males and 1–3 in females, and ventromedial setae on segments 3–9 in males and 4–9 in females. The diagnostic features of Setaphyes algarvensis sp. nov. are discussed from a comparative perspective with the congener species. Additionally, morphometric analyses of selected features, namely the total trunk length and the relation between the total trunk length and the length of lateral terminal spines, turned out to be useful to distinguish between the new species and Setaphyes kielensis (its most similar congener).
A revision of microscope slides deposited between 2014 and 2017 in the collection of Rocha and Doma (National University of La Pampa, Argentina) revealed three new species of the genus Milnesium Doyère, 1840: M. pelufforum sp. nov., M. irenae sp. nov. and M. quiranae sp. nov. Milnesium pelufforum sp. nov. is mostly characterized by ten transverse bands of sculptured cuticle and pseudoplates (the first band, until now, never detected in the genus), six peribuccal lamellae and claw configuration [2-2]-[2-2] in young or [2-3]-[3-2] in senior specimens. Milnesium irenae sp. nov. is mostly characterized by complex cuticular ornamentation including a fine reticulation different from the typical one in the genus; it also has pseudoplates, six peribuccal lamellae, medioventral peribuccal papilla reduced, stylets, their furcae and supports very developed, and claw configuration [2-3]-[2-2]. Milnesium quiranae sp. nov. is mostly characterized by smooth cuticle, six peribuccal lamellae, and claw configuration [3-3]-[3-3]; with growing, the medioventral peribuccal papilla reduces and the buccal tube becomes wider. With the present contribution the genus Milnesium now has 48 valid species, and the number of described limno-terrestrial tardigrade species from South America has risen to 11, including 8 from Argentina with 5 from Salta and La Pampa province.
The pseudoscorpion (Arachnida: Pseudoscorpiones) fauna of mainland Ecuador, excluding the Galápagos Islands, is poorly known, with only 41 described species in 9 families. The family Syarinidae has a pantropical distribution and presently comprises ca 120 species in 17 valid genera that are found in leaf litter and subterranean habitats, mostly in tropical and subtropical climates. Four syarinid species have been recorded from Ecuador, including the Galápagos, in two widespread genera, Ideobisium and Ideoblothrus, but field collections suggest that these pseudoscorpions are common and abundant in all forest systems across the country. Here, we review field collections of syarinids from mainland Ecuador and describe five new species in these genera: Ideobisium kichwa sp. nov. (Napo Province, Colonso Chalupas Natural Reserve), I. sonqo sp. nov. (Napo Province, Colonso Chalupas Natural Reserve), I. susanae sp. nov. (Napo Province, Jatun Sacha Natural Reserve), Ideoblothrus nadineae sp. nov. (Napo Province, Colonso Chalupas Natural Reserve) and I. safinai sp. nov. (Pichincha Province, Otongachi Natural Reserve) based on morphology. These species seem to have narrow distributions and we therefore restrict the ranges of two species previously recorded from Ecuador (Ideobisium crassimanum Balzan, 1892 and Ideoblothrus costaricensis (Beier, 1931)) to their countries of origin, which is Costa Rica and Venezuela, respectively.
