New World species of the histerid beetle genus Xestipyge Marseul (Coleoptera: Histeridae: Dendrophilinae: Paromalini) are reviewed, and X. skelleyi, new species, is described. A dichotomous key and illustrations are provided as identification means for the now five included species from the Western Hemisphere.
India is a large country in Asia, and covers the transition zone between the Palaearctic and Indomalayan biogeographic realms, with influences from both. Present in India are members of the genus Andrena, an enormous bee genus distributed predominantly throughout the Holarctic, with the greatest Indian diversity in the Himalayan region due to its Palaearctic influences. Despite early studies in the late 19th and early 20th centuries, there has been almost no work on this group in India during the past century. A revision of type and non-type museum material combined with new collections has produced a revised total of 36 species of Andrena for India, including 11 species reported for the first time as well as the newly described Andrena (Melandrena) kedarnatha Wood & Gautam sp. nov. (northern India and Nepal) and Andrena (Simandrena) tungnatha Wood & Gautam sp. nov. (northern India). The true holotype of A. (Euandrena) communis Smith, 1879 is definitively located. Andrena burkelii Bingham, 1908 is synonymised with A. (Pallandrena) morosa Cameron, 1897. Lectotypes are designated for A. (Euandrena) murreensis Cockerell, 1923 and A. (incertae sedis) comberima beharica Cockerell, 1920. Further comments are made on the status of Andrena taxa described from India for which type material is and is not currently available. Thirty additional Andrena taxa suggested as present in the Indian fauna are excluded as either erroneous or lacking supporting data. These results illustrate the extent to which study of the Indian Andrena fauna has been confused, and provide a more stable taxonomic base for future studies in this country.
Dual-task paradigms encompass a broad range of approaches to measure cognitive load in instructional settings. As a common characteristic, an additional task is implemented alongside a learning task to capture the individual’s unengaged cognitive capacities during the learning process. Measures to determine these capacities are, for instance, reaction times and interval errors on the additional task, while the performance on the learning task is to be maintained. Opposite to retrospectively applied subjective ratings, the continuous assessment within a dual-task paradigm allows to simultaneously monitor changes in the performance related to previously defined tasks. Following the Cognitive Load Theory, these changes in performance correspond to cognitive changes related to the establishment of permanently existing knowledge structures. Yet the current state of research indicates a clear lack of standardization of dual-task paradigms over study settings and task procedures. Typically, dual-task designs are adapted uniquely for each study, albeit with some similarities across different settings and task procedures. These similarities range from the type of modality to the frequency used for the additional task. This results in a lack of validity and comparability between studies due to arbitrarily chosen patterns of frequency without a sound scientific base, potentially confounding variables, or undecided adaptation potentials for future studies. In this paper, the lack of validity and comparability between dual-task settings will be presented, the current taxonomies compared and the future steps for a better standardization and implementation discussed.
A glance at the Odonata of the Cambodian coastal mountainous regions : end of dry season in 2010
(2010)
During a visit to the coastal regions of Cambodia within the Provinces of Koh Kong, Kampong Saom, Kampot and Kep within April 12-23, 2010, 59 species of Odonata were found. Of these, 51 were identified, 2 preliminarily identified (1 by exuviae, 1 to a known species with the valid name unresolved), 1 dubious (Aciagrion cf. pallidum), 3 not identified (just visual observations) and 2 seemingly undescribed, namely Burmagomphus sp. and Microgomphus sp. Fourteen species were recorded for the first time for this country, namely Neurobasis chinensis, Dysphaea gloriosa, Euphaea masoni, Onychargia atrocyana, Copera marginipes, Copera vittata, Prodasineura autumnalis Prodasineura verticalis sensu Asahina, 1983, Lathrecista asiatica, Orthetrum chrysis, Rhyothemis obsolescens, Tramea transmarina euryale, Zygonyx iris malayana, Zyxomma petiolatum; taking the current checklist for Cambodia up to 83 species. Some features of the collected specimens relevant to their taxonomy are discussed. Brief field notes are provided and Odonata records enumerated. The habitats and community of Odonata at the Cardamon Mts. foothills at the end of dry season are discussed.
A new genus in the tribe Issini (Hemiptera: Fulgoromorpha: Issidae) is described from South China: Orbita Meng & Wang, gen. nov., its type species Orbita parallelodroma Meng & Wang, gen. et sp. nov. (China: Fujian) is described and illustrated. In addition, one new species of Neokodaiana Yang, N. minensis sp. nov. is described and illustrated from the same locality as the new genus. A key to the genera of Issini from China and neighbouring countries is provided.
Although extensively studied by different authors over the past 150 years, the taxonomy of Canthon Hoffmannsegg, 1817 and allied genera (which are here informally referred to as 'Canthon sensu lato') still remains problematic. With the aim of resolving some of the questions surrounding these taxa, the present work reviews the taxonomy of one of them, the genus Sylvicanthon Halffter & Martínez, 1977. As defined here, Sylvicanthon is distributed mainly throughout the vast areas of tropical rainforests in the Neotropical region and includes 15 species divided into two groups: the enkerlini group, with a single species, S. enkerlini (Martínez et al., 1964) comb. nov., and the candezei group, with five subgroups: the candezei subgroup, with S. candezei (Harold, 1869), S. genieri sp. nov. and S. foveiventris (Schmidt, 1920); the aequinoctialis subgroup, with S. aequinoctialis (Harold, 1868) comb. nov. and S. proseni (Martínez, 1949) stat. et comb. nov.; the bridarollii subgroup, with S. bridarollii (Martínez, 1949), S. seag sp. nov., S. edmondsi sp. nov. and S. attenboroughi sp. nov.; the furvus subgroup, with S. furvus (Schmidt, 1920), S. monnei sp. nov., S. mayri sp. nov. and S. obscurus (Schmidt, 1920); and the securus subgroup, with a single species, S. securus (Schmidt, 1920) comb. nov. Three species originally included in Sylvicanthon are here (re)transferred to Canthon: Canthon xanthopus Blanchard, 1846 and C. machadoi (Martínez & Pereira, 1967) comb. nov., as well as C. cobosi (Pereira & Martínez, 1960) stat. et comb. nov., which had been previously in synonymy under C. xanthopus. Descriptions, redescriptions, illustrations and comparative tables on the external morphology (including the genital capsule) of the genus and its species are presented, as well as a detailed discussion on their biogeography, comparative morphology, hypotheses on their phylogenetic relationships, data on natural history and a detailed historical revision of the classification of 'Canthon sensu lato'. Finally, we also discuss the socalled 'species problem' (i.e., the definition of the scientific term 'species') and its consequences to dung beetle taxonomy and favour the solution offered by the Biological Species Concept.
A morphological and molecular review of the genus Goniurosaurus, including an identification key
(2021)
The genus Goniurosaurus (tiger geckos) currently consists of 23 species distributed in China, Japan and Vietnam. Several species complexes and recent discoveries of cryptic species pose challenges to the species identification, which is crucial to effectively implement the recent listing of the species from China and Vietnam in CITES Appendix II and the species from Japan in CITES Appendix III. Based on the results of our field work in northern Vietnam and data compiled from literature, we herein provide a taxonomic review of the genus Goniurosaurus. Our phylogenetic analyses showed that all recorded populations of tiger geckos from Vietnam, which were found to be monophyletic with low intra-specific genetic divergences, are assigned to one of the four species: G. catbaensis, G. huuliensis, G. lichtenfelderi or G. luii. Both genetic and morphological analyses confirm that the species from China and Vietnam can be split into three major groups. Based on the newly collected data, we provide an extended morphological description of the Vietnamese species. In addition, we provide an identification key for all Goniurosaurus species from China, Japan and Vietnam in order to assist authorities in the enforcement of the recent CITES listing.
Twenty new species of the millipede genus Chaleponcus Attems, 1914, are described from the Udzungwa Mountains: C. netus sp. nov., C. quasimodo sp. nov., C. malleolus sp. nov., C. scopus sp. nov., C. nikolajscharffi sp. nov., C. mwanihanensis sp. nov., C. basiliscus sp. nov., C. krai sp. nov., C. nectarinia sp. nov., C. circumvallatus sp. nov., C. ibis sp. nov., C. vandenspiegeli sp. nov., C. vilici sp. nov., C. teres sp. nov., C. hamerae sp. nov., C. termini sp. nov., C. gracilior sp. nov., C. mwabvui sp. nov., C. howelli sp. nov. and C. tintin sp. nov. Together with C. dabagaensis Kraus, 1958, they constitute the Chaleponcus dabagaensis-group, well characterized by apparently apomorphic gonopodal characters, presumably monophyletic, and the first example of a major radiation within the Udzungwas. All species are restricted to altitudes >1390 m, all but one were found in only one, rarely two forest reserves, and the vast majority of specimens were collected in montane forest. Chaleponcus gracilior sp. nov. was collected in four forest reserves, often in secondary habitats where other species were only exceptionally found. Co-occurrence of multiple species, inter-specific differences in body size and unusual tarsal setation of a few species tentatively suggest adaptive radiation.
The genus Aquattuor Frederiksen, 2013 is revised. A. denticulatus Frederiksen, 2013 (type species) from the East Usambara Mts, Tanzania, is redescribed, and six new species are described: A. claudiahempae sp. nov. from Mt. Kilimanjaro, Tanzania, and five species from the Udzungwa Mts, Tanzania: A. longipala Enghoff sp. nov., A. major Enghoff sp. nov., A. stereosathe Enghoff sp. nov., A. submajor Enghoff sp. nov., and A. udzungwensis Enghoff sp. nov.
The new genus Geotypodon gen. nov. is described. It includes two species from the Udzungwa Mountains: G. millemanus gen. et sp. nov. (type species) and G. submontanus gen. et sp. nov., one species from nearby Iringa: G. iringensis gen. et sp. nov., and 18 previously described species hitherto incorrectly assigned to Odontopyge Brandt, 1841.
Two species of the genus Prionopetalum Attems, 1909, are recorded from the Udzungwa Mountains: P. asperginis sp. nov. and P. kraepelini (Attems, 1896). Prionopetalum stuhlmanni Attems, 1914, is synonymized under P. kraepelini. Odontopyge fasciata Attems, 1896, is transferred from Prionopetalum to Aquattuor Frederiksen, 2013, and new illustrations are given. A new illustrated key to species of Prionopetalum is provided.
Three new genera of Odontopygidae are described, all based on new species from the Udzungwa mountains, Tanzania, and all monotypic: Casuariverpa gen. nov. (type species: C. scarpa gen. et sp. nov.), Yia gen. nov. (type species: Y. geminispina gen. et sp. nov.), and Utiliverpa gen. nov. (type species: U. decapsulatrix gen. et sp. nov.). Similarities and differences between the new genera and other genera are discussed.
Damacornu gen. nov. (type species: D. transversum gen. et sp. nov.), Geotypodon papei sp. nov. and Spinotarsus fortehamatus sp. nov. are described, and Helicochetus dimidiatus (Peters, 1855), H. mutaba Kraus, 1960 and Hoffmanides dissutus (Hoffman, 1963) are recorded from the Udzungwa Mts, Tanzania. A complete overview of the 39 odontopygid species now known from the Udzungwa Mts is given, including notes on endemism, biogeographical relationships and altitudinal distribution patterns.
A large, newly collected material of the genus Aquattuor from the Udzungwa Mts, Tanzania, has been studied. Two new species are described, viz., A. mollilobus sp. nov. from the Udzungwa Mts and A. nguruensis sp. nov. from the Nguru Mts, Tanzania. Aquattuor claudiahempae Enghoff & Frederiksen, 2015, is recorded as new for the Udzungwa fauna. Characters from the first pair of male legs are illustrated for all Aquattuor species and are shown to be useful for species discrimination. A new gonopodal difference between A. submajor Enghoff, 2015 and A. udzungwensis Enghoff, 2015 is described and illustrated. Intrageneric relationships and distribution patterns are discussed. A distribution map and a key to all Aquattuor species are presented.
Three new species of the family Pyrgodesmidae Silvestri, 1896 from the Udzungwa Mountains are described: Cryptocorypha geminiramus sp. nov., Cryptocorypha cactifer sp. nov., and Cryptocorypha exovo sp. nov. Several additional, unidentifiable pyrgodesmids from the Udzungwa Mountains are recorded. Elythesmus enghoffi Hoffman, 1978 (Cryptodesmidae Karsch, 1880), is recorded from the East Usambara (type locality), West Usambara, Uluguru, Nguru (Kanga) and Udzungwa Mountains, and its variation in size and body ring numbers is analyzed. The surface sculpture of pro- and metazonites is discussed.
The “trachystreptoform” species of Spirostreptidae, i.e., species which would formerly have been ascribed to the tribe Trachystreptini, from the Udzungwa Mountains are (re)described, including one new genus and five new species: Attemsostreptus reflexus Akkari & Enghoff, 2019, A. cataractae Enghoff sp. nov., A. leptoptilos Enghoff sp. nov., A. julostriatus Enghoff sp. nov., Lophostreptus tersus (Cook, 1896) (= L. ptilostreptoides Carl, 1909 syn. nov.), L. magombera Enghoff sp. nov., and Udzungwastreptus marianae Enghoff gen. et sp. nov. The type material of Lophostreptus regularis Attems, 1909 (= L. tersus) is discussed. The discussion includes paragraphs on the classification and the Udzungwa fauna of Spirostreptidae, on grouping of the Udzungwa trachystreptoform species in relation to altitude, and on the possibly recent immigration of A. reflexus and L. tersus into the Udzungwa Mts.
Lodevoisadia coheni gen. et sp. nov. is described as the ninth species of ‘Grylloblattodea’ from the middle Permian of the Salagou Formation, near Lodève town (France). It is currently not reasonable to place this species into a specific family, even though it seems to share most characters with the small family Tunguskapteridae. The lack of phylogenetic analysis and the current poor delineation of the majority of the grylloblattodean families (lacking synapomorphies) render any attribution of new taxa to a particular family often uncertain.
Bureschia serbica sp. nov., is described from a cave in the Stara Planina Mt in Serbia as a second species in the genus. It is a troglobite amphibious species, predominantly aquatic like the nominal species of the genus, Bureschia bulgarica. The new species is adapted to amphibious life in running groundwater, unlike the nominal one that lives in subterranean lakes and ponds. Body structure changes, most noticeable the significant changes in the structure of the mouthparts, as a result of preadaptation in aquatic and amphibious Synocheta, are discussed.
A new planthopper genus, Aodingus Chen & Li gen. nov. and three new species (A. hainanensis Chen & Li gen. et sp. nov., A. obscurus Chen & Li gen. et sp. nov. and A. cuongi Chen & Li gen. et sp. nov.) are described from China and Vietnam. The new genus is superficially similar to Procidelphax Bartlett, 2009 in general appearance in that the body is strongly dorsoventrally flattened. Distinctive features of the new taxon include broadly compressed body with vertex broad, apical margin broadly rounded, middle part concave, median and submedian carinae absent, frons broad and large, wider at base than at apex, forewing broad and long, aedeagus tubular, curved ventrally. A diagnosis for all species, illustrations and an identification key of new genus are provided. A key to the Chinese genera of Tropidocephalini is also provided.
The lichen-forming genus Pertusaria under its current circumscription is polyphyletic and its phylogenetic affiliations are uncertain. Here we study the species of the genera Pertusaria and Varicellaria which containlecanoric acid as major constituent, have disciform apothecia, strongly amyloid asci, non-amyloid hymenial gel, 1-2-spored asci, and 1- or 2-celled ascospores with thick, 1-layered walls. We infer phylogenetic relationships using maximum likelihood and Bayesian analyses based on four molecular loci (mtSSU, nuLSU rDNA, and the protein-coding, nuclear RPB1 and MCM7 genes). Our results show that the lecanoric acid-containing species form a well-supported, monophyletic group, which is only distantly related to Pertusaria s.str. The phylogenetic position of this clade is unclear, but placement in Pertusaria s.str. is rejected using alternative hypothesis testing. The circumscription of the genus Varicellaria is enlarged to also include species with non-septate ascospores. Seven species are accepted in the genus: Varicellaria culbersonii (Vězda) Schmitt & Lumbsch, comb. nov., Varicellaria hemisphaerica (Flörke) Schmitt & Lumbsch, comb. nov., Varicellaria kasandjeffii (Szatala) Schmitt & Lumbsch, comb. nov., Varicellaria lactea (L.) Schmitt & Lumbsch, comb. nov., Varicellaria philippina (Vain.) Schmitt & Lumbsch, comb. nov., Varicellaria rhodocarpa (Körb.) Th. Fr., and Varicellaria velata (Turner) Schmitt & Lumbsch, comb. nov. A key to the species of Varicellaria is provided.
A new cryptic species, Aleochara (Xenochara) castaneimarmotae Klimaszewski, Webster, and Brunke, new species (Coleoptera: Staphylinidae: Aleocharinae), associated with Marmota monax (Linnaeus) burrows and caves in eastern North America, is described and illustrated. A key to Canadian species of subgenus Xenochara Mulsant and Rey and revised distributions of the taxonomically difficult fumata species group are provided. Aleochara quadrata Sharp is recorded from Washington and Oregon for the first time.
A new cypridopsine genus, Cyprettadopsis gen. nov., described here, is principally characterized by the reduced caudal ramus, the strongly serrated claw G2 of the antenna (A2), the A2 subquadrate terminal segment, the undivided penultimate segment of the second thoracopod (T2), the morphology of the third thoracopod bearing a distinctly separated terminal segment, the complete septa on the posteroventral margin and the incomplete septa on the anterior margin of both valves. Based on a combination of these characters, a new tribe, Cyprettadopsini trib. nov., is created in the subfamily Cypridopsinae Kaufmann, 1900 to accommodate this new genus, and one new species, Cyprettadopsis sutura gen. et sp. nov., is described as the type species. Apart from the above generic characters, the following features are also typical of the new species: the tiny needlepoint-like pores along the anterior and ventral margins of both valves, the remarkably large β-seta on the mandibular palp and the considerably short d2 seta on the T2. The presence of marginal septa in the new genus is a distinctive character and constitutes the first record of this feature within Cypridopsinae. The taxonomically relevant characters in the new taxon and related taxa are briefly discussed.
We describe a new species of Cyrtodactylus on the basis of two specimens collected from Ta Kou Nature Reserve, Binh Thuan Province, southern Vietnam. Cyrtodactylus chungi sp. nov. is distinguished from the remaining Indochinese bent-toed geckos by a combination of the following characters: relatively small body size (SVL up to 68.5 mm); a continuous neckband; 5 or 6 irregular transverse dorsal bands; 11 or 12 bands on original tail; keeled tubercles present on dorsum, posterior limbs and tail; 17 or 18 irregular dorsal tubercle rows; 30 or 31 ventral scale rows; ventrolateral skin folds indistinct; an angular series of seven precloacal pores in male and six pitted, enlarged precloacal scales in female, each series separated by a diastema of undifferentiated scales from 4–6 enlarged, poreless femoral scales; median subcaudals slightly enlarged; 17–20 subdigital lamellae under the fourth toe. Based on molecular analyses of the fragment of mitochondrial gene cytochrome c oxidase subunit I (COI), the new species is recovered as the sister taxon to Cyrtodactylus cattienensis s. str. with a genetic divergence of more than 9%. In phylogenetic analyses, the new species is recovered as a member of the Cyrtodactylus irregularis species group.
A new feature for the separation of Trochosa spinipalpis and T. terricola males (Araneae, Lycosidae)
(2006)
A new feature on the tip of the palp, which enables the separation of male Trochosa spinipalpis (F. O. P.-Cambridge, 1895) from T. terricola Thorell, 1856, is described. T. terricola exhibits a hairless strip on the tip of the palp, while T. spinipalpis lacks this feature and has long hairs on the whole palp.
Here I describe a new genus, Iviephengus gen. nov., based on a single species, Iviephengus ferreirai gen. et sp. nov., from Peru. This new genus is characterized by the following combination of characters: interantennal distance close to 3 × the antennal socket length; antenna 12-segmented, IV to XI each with two long symmetrical compressed and apically slightly enlarged branches; labrum fused to frontoclypeus; mandibles short, obliquely crossed, each with a notch on the external margin to fit the other mandible and without extra teeth; maxillary palpi 4-segmented, last segment digitiform; labial palpi 2-segmented; posterior tentorial pit consisting of a single small fossa; wing with radial cell closed and transverse, vein r4 interrupted, r3 absent; first tarsomere of pro- and mesotarsus with a ventral comb covering the posterior half of the tarsomere; claws simple, without any teeth; aedeagus with paramere symmetrical, apex unevenly round, toothed inward, with short and sparse bristles. I provide a key to Mastinocerinae genera with 12-segmented antennae and the first pro- and mesotarsomere with ventral combs. I also provide illustrations for the diagnostic features for this new genus. Finally, I discuss the presence and function of some modifications in the mandible and the sternite VIII in Phengodidae and other Coleopteran families.
A new Brazilian leafhopper genus of the subfamily Neocoelidiinae is proposed: Takiyaella gen. nov. based on T. sexguttata (Chiamolera & Cavichioli, 2003) gen. et comb. nov. and five new species: T. anomala gen. et sp. nov., T. coelhomarquesae gen. et sp. nov., and T. daniela gen. et sp. nov. from the state of Rio de Janeiro; T. cavichiolii gen. et sp. nov. from the state of Paraná, and T. mejdalanii gen. et sp. nov. from the state of Minas Gerais. A distribution map and identification key to Takiyaella species are provided.
Thomsonista Nearns and Nascimento, a new genus of Onciderini Thomson, 1860 (Coleoptera: Cerambycidae: Lamiinae), is described and illustrated. Seven new species of Onciderini are described and illustrated: Hesychotypa antonkozlovi from Ecuador; Hesychotypa danilevskyi from Panama; Lingafelteria pandolfii from Brazil; Oncideres antonkozlovi and Oncideres erwini from Peru; Oncideres johnmarvini from Costa Rica and Panama; and Thomsonista antonkozlovi from Colombia.
Abstract. More than 1300 specimens of Eucnemidae collected from Heredia Province in Costa Rica during the 1990s Arthropods of La Selva (ALAS) survey were studied from 2018 through 2022. One new genus of false click beetle, Absensiugum Otto, Muona and Córdoba-Alfaro, is described. Nematodes teres Horn, from the Nearctic and Caribbean regions, is transferred to this new genus to form Absensiugum teres, new combination. Sixteen new species of false click beetle (Coleoptera: Eucnemidae) are described from Costa Rica. These new species are: Adelothyreus brevis, Adelothyreus costaricensis, Adelothyreus totus, Quirsfeldia stethonoides, Lacus pectinatus, Maelodrus costaricensis, Onichodon confluentus, Onichodon rufus, Isarthrus striatus, Absensiugum brunneum, Dromaeolus americanus, Dromaeolus brunneus, Dromaeolus herediensis, Dromaeolus holdridgei, Deltometopus bicolor and Nematodes apicalis. Three additional records outside of the Heredia Province from the Osa Peninsula and Panama for Lacus pectinatus are included in this study. Identification keys are provided for species of Adelothyreus Chevrolat, Onichodon Newman, Dromaeolus Kiesenwetter, Deltometopus Bonvouloir and Nematodes Berthold in Costa Rica. Diagnostic differences are briefly noted for each species within the Neotropical region. A list of Eucnemidae from Heredia Province is provided.

Serratichneumon Riedel & Sheng gen. nov. and Serratichneumon maculatus Sheng & Riedel gen. et sp. nov. belonging to the tribe Ichneumonini of subfamily Ichneumoninae (Hymenoptera: Ichneumonidae), collected in the Oriental Region (China, Vietnam, and Indonesia), are described and illustrated. The new genus is placed in Tereshkin’s key to the Palaearctic genera of the subtribe Amblytelina, and compared with similar genera, Hepiopelmus Wesmael, 1845, and Tricholabus Thomson, 1894.
A new fossil ceratopogonid genus and species from Lower Cretaceous Lebanese amber, Baskintoconops maaloufi Pielowska-Ceranowska gen. et sp. nov., is described and illustrated. The studied material originates from a newly discovered amber site in the Lebanese village Baskinta at a locality dubbed Qanat Bakish. The described genus is typified by its wing venation pattern combining characters of genera Fossileptoconops and Jordanoconops belonging to the subfamily Leptoconopinae.
A new genus and new species of Onciderini Thomson, 1860 (Coleoptera: Cerambycidae: Lamiinae) are described and illustrated: Velozideres buntyni, from Ecuador. The following two new synonymies in Onciderini are proposed: Oncideres paurosoma Noguera, 1993 = Microcanus minor (Bates, 1885); Oncioderes piauiensis Martins and Galileo, 2013 = Oncioderes rondoniae Martins and Galileo, 1990. The following seven new country records are reported: Clavidesmus chicae Giorgi, 1998 (Onciderini) (Argentina); Ecthoea quadricornis (Olivier, 1795) (Onciderini) (Venezuela); Oncideres ophthalmalis Dillon and Dillon, 1946 (Onciderini) (Costa Rica); Oncideres punctata Dillon and Dillon, 1946 (Onciderini) (El Salvador); Oncideres xavieri Galileo and Martins, 2010 (Onciderini) (Peru); Trestonia signifera Buquet, 1859 (Onciderini) (Brazil); and Oideterus crenatocerus (Galileo, 1987) (Cerambycidae: Prioninae: Anacolini) (Costa Rica).
A new polynoid, Webbnesia maculata gen. et sp. nov., was discovered during benthic surveys conducted around the Canary Islands. Its generic characters (absence of cephalic peaks, ventrally inserted lateral antennae, reduced notopodium and chaetae all stout) place it close to Antinoe Kinberg, 1856, Hermadion Kinberg, 1856 and Malmgrenia McIntosh, 1874, but the combination is unique and justifies the erection of a new genus. The new genus and species are described, figured and discussed in detail. An updated list of taxa and an identification key to all genera of Polynoinae Kinberg, 1856 sensu lato currently reported from the extended Northeast Atlantic are given.
A new genus and species of Sternaspidae (Annelida: Polychaeta) from the deep eastern Atlantic
(2020)
Based on specimens recently collected in sediments from 2700 m depth off Mauritania (Northwest Africa; type locality) and from 2700–4400 m depth off Angola (Southwest Africa), a new genus and species, Mauretanaspis longichaeta gen. et spec. nov., is described. The new genus and species are characterized by a unique combination of characters: ventro-caudal shield covered by firmly adhering sediment, lateral margins strongly bent and merging into integument; introvert hooks tapering; eight pre-shield segments; absence of peg chaetae; exceptionally long posteriormost lateral chaetae equaling body length; posterior shield chaetae equaling shield length. A comparative table of characters for all currently recognised sternaspid genera and a key to all species with ventro-caudal shield covered by firmly adhering sediment are provided.
Susamyia Ziegler & Gilasian gen. nov. and its type species Susamyia mira Ziegler & Gilasian gen. et sp. nov. are described from southwestern Karkheh National Park and southeastern Jazmourian Wetland of Iran. Drawings of terminalia and head of the male as well as images of habitus, head and egg are provided. Susamyia gen. nov. is incorporated into the identification key to the Palearctic tachinid genera of Tschorsnig & Richter (1998). The systematic position of Susamyia gen. nov. in the tribe Goniini (Exoristinae) is discussed in light of molecular analyses based on the ribosomal genes 16S, 18S and 28S, and the egg type of females. The morphology of the microtype eggs was studied and compared with that of other Goniini, but proved too unreliable to be included in the phylogenetic analysis. Susamyia gen. nov. is believed to be most closely related to the goniine genera Gymnophryxe Villeneuve, 1922, Palesisa Villeneuve, 1929 and Prosopodopsis Townsend, 1926.
A new genus of jumping spiders, Bavirecta gen. nov. is proposed to include the type species B. flavopuncta gen. et sp. nov. and Bavirecta exilis (Cao et al., 2016) gen. et comb. nov. Distinguishing characters of Bavirecta gen. nov. include: 1) tubular abdomen, 2) enlarged front legs, 3) straight and
pointed embolus, broadest proximal lobe with black blotches, 4) prolateral tegular lobe, 5) widely separated anterior atria. Furthermore, two new species, Schenkelia aurantia sp. nov. (♂♀) and Brancus calebi (♂) sp. nov., are described and diagnosed. Mogrus frontosus (Simon, 1871) is redescribed based on a male collected from Mandaitivu Island of Jaffna District in Sri Lanka. The genera Brancus Simon, 1902, Mogrus Simon, 1882 and Schenkelia Lessert, 1927 are reported for the first time from Sri Lanka
(Brancus and Schenkelia are recorded for the first time outside Africa).

Ysachron pilosus gen. et sp. nov. is described from the Caribbean region of Colombia, and an updated key to genera of South American Achrysonini is provided. Moreover, the geographical distribution of 45 species of Cerambycidae, belonging to the subfamilies Cerambycinae, Lamiinae and Prioninae, is expanded, including nine new country records for Colombia and a further locality in Colombia for nine species.
Two small, ground and litter-dwelling pholcid species from northern Borneo are described as representatives of a new genus, Hantu gen. nov.: H. kapit gen. et sp. nov. and H. niah gen. et sp. nov. Previous cladistic analyses suggested a closer relationship with the genera Savarna Huber, 2005 and Khorata Huber, 2005 (mainland Southeast Asia) than with the geographically closer genus Aetana Huber, 2005 (Borneo and Philippines to Fiji). Since the two species do not share any of the synapomorphies of Khorata and Savarna while having several synapomorphies on their own (ventral apophysis on male palpal coxa; male palpal trochanter apophysis with small teeth or scales; spines on male femora 1; high density of vertical hairs on male femora; presence of scape on epigynum), they are here proposed as representing a new genus.
The genus Koiulus gen. nov. and its type-species, Koiulus interruptus gen. et sp. nov., are described from the Russian Far East. The new genus is compared with other genera of Mongoliulidae, in particular with Ussuriiulus Golovatch, 1980, also from the Russian Far East, with which it shares the absence of ozopores from individual body rings distributed along the body, a condition so far otherwise unknown in the superorder Juliformia. A synoptic table of genera and a list of species of Mongoliulidae are presented.
Afrocampe gen. nov. is described for its only species, A. prinslooi gen. et sp. nov., from Eastern and Western Cape, South Africa. This new genus is recognized as a member of the subfamily Tetracampinae Förster, 1856 of Tetracampidae Förster, 1856 based on the possession of 5-segmented tarsi in females and 4-segmented tarsi in males, the short straight calcar, the mesoscutum with distinct notauli, the mesoscutellum with two pairs of setae, the reduced mesopleural suture and the short stigmal and long postmarginal veins of the fore wing. Afrocampe gen. nov. is characterized by a large mesosoma, a non-convex first gastral tergite, an evenly acute calcar, a 5-segmented antennal funicle, a head lacking occipital carina and facial grooves and a long fore wing with distinctly delimited speculum, a bare admarginal area with a distinct admarginal row of setae on the underside and with 3 setal tracks (hair rows) radiating from the apex of the stigmal vein. The combination of these characters suggests a special status of the new genus within the subfamily Tetracampinae. Moreover, Afrocampe gen. nov. bears some resemblance to the Australian tetracampine genus Niticampe Bouček, 1988. The position of the latter in Tetracampinae, as well as habitus features of the former, are discussed.
Magnacarina gen. nov. from Mexico is described. Hapalopus aldanus West, 2000 from Nayarit, is transferred to the new genus with an emended diagnosis creating the new combination Magnacarina aldana comb. nov. Three new species are described: Magnacarina moderata Locht, Mendoza & Medina sp. nov. from Nayarit and Sinaloa; Magnacarina primaverensis Mendoza & Locht sp. nov. and Magnacarina cancer Mendoza & Locht sp. nov., both from Jalisco. Magnacarina gen. nov. is characterized by an unusual bifid palpal bulb, and has a primary projection located in the central area of the palpal bulb and directed retrolaterally; this projection possesses the prolateral superior and retrolateral keels. Next to the primary projection is a secondary projection, which may be short or long, ending in the prolateral inferior and apical keel surrounding the sperm pore. This secondary projection may have prolateral accessory keels and is diagnosed by possessing a nodule of inwardly curled megaspines, located in the basal ventro-retrolateral region of metatarsi I in adult males. Additionally, male tibiae I possess three apophyses. Females of Magnacarina gen. nov. have a single reduced and strongly sclerotized spermatheca, with an apical lobe projecting ventrally, and with a uterus externus that is longer and wider than the spermatheca.
An early, overlooked description of the genus Atelodesmis (Coleoptera, Cerambycidae, Lamiinae) is attributed to Chevrolat (in Duponchel and Chevrolat 1841), with A. mannerheimii Duponchel and Chevrolat, 1841 as its type species, and the genus redescribed. Atelodesmis Buquet, 1857, is a junior synonym and primary homonym of Atelodesmis Chevrolat. Atelodesmis hirticornis Buquet, 1857 and A. vestita Buquet, 1857 are synonymized with A. mannerheimii. Fallaxdesmis is described as a new genus with Atelodesmis unicolor Buquet, 1857 as type species. Atelodesmis piperita Bates, 1855 is transferred to Eupogonius and newly recorded for the state of Oaxaca, Mexico. A new species for Mexico and Guatemala, Eupogonius giesberti, is described. The following new combinations are established: Fallaxdesmis unicolor (Buquet, 1857) and Eupogonius piperita (Bates, 1855). Illustrations of A. mannerheimii, Fallaxdesmis unicolor, and the holotypes of A. hirticornis, A. vestita, A. unicolor, A. piperita and Eupogonius giesberti are included.
We describe the frog species Diasporus citrinobapheussp. n. from the Cordillera Central of western Panama. The new species differs from all other species in its genus in coloration, disk cover and disk pad shape, skin texture, advertisement call, and size. It is most similar to Diasporus tigrillo, from which it differs in dorsal skin texture, relative tibia length, number of vomerine teeth, ventral coloration, dorsal markings, and relative tympanum size, and to Diasporus gularis, from which it can be distinguished by the lack of membranes between the toes, adult size, posterior thigh coloration, and position of the choanae. We provide data on morpho- logy, vocalization, and distribution of the new species, as well as brief information on its natural history.
A new mesoserphid wasp from the Middle Jurassic of northeastern China (Hymenoptera, Proctotrupoidea)
(2017)
A new genus and species of Mesoserphidae (Hymenoptera), Juraserphus modicus gen. et sp. nov., is described based on a well-preserved fossil specimen from the Middle Jurassic Jiulongshan Formation of northeastern China. It is characterized by the following forewing features: the forking of Rs+M located approximately one-third of the distance between 1m-cu and 2r-rs, both 1cu-a and 2cu-a antefurcal; 1-M more than twice as long as 1m-cu and hind wing with cells r and rm closed. In addition, it has a short ovipositor, only extending slightly beyond the metasomal apex. Its new morphological characters broaden the diversity of Mesoserphidae in the Mesozoic and provide new insights into the evolution and relationships of Mesoserphidae.
We describe and illustrate a new Neotropical predaceous midge, Parabezzia carlae Huerta, Spinelli and Grogan, new species (Diptera: Ceratopogonidae) from males collected by Malaise trap in La Union, Ayutla de los Libres, state of Guerrero, Mexico. We also report a second record of P. alexanderi Wirth from Veracruz, Mexico. A key to the known species in Mexico is included.
New records for a new species and other exotic Dirrhagofarsus Fleutiaux (Coleoptera: Eucnemidae: Melasinae: Dirhagini) species are reported from throughout much of the northeastern and southern areas of the United States. Dirrhagofarsus brevis, new species, is hereby described in this study. Two other exotic species, Dirrhagofarsus modestus (Fleutiaux) and Dirrhagofarsus unicolor (Hisamatsu), new country records, are redescribed and diagnosed as they were compared with other Dirrhagofarsus species present in the Nearctic region. All Dirrhagofarsus species in this study are imaged, highlighting essential character states to facilitate better diagnosis in conjunction to the new identification key provided in this study.

Fractipes tayrona new species (Coleoptera: Chrysomelidae: Eumolpinae: Eumolpini) is described from a dry forest on the Caribbean coast of Colombia. This locality is very distant from the localities in southeast Brazil, where the other two known species of Fractipes Bechynĕ were described. Male and female genitalia are described for the first time in this genus, and F. tayrona is compared with holotype photographs of F. rhabdopteroides Bechynĕ and F. secundus Bechynĕ and Springlová de Bechynĕ.
Phymatodes (Phymatodes) huetheri Wappes and Santos-Silva (Coleoptera: Cerambycidae: Cerambycinae: Callidiini) from upstate New York, USA and Canada is described and illustrated. Phymatodes (Phymatodes) rainieri Van Dyke, 1937 is placed in synonymy with Phymatodes (Phymatodes) fulgidus Hopping, 1928.
A new species of Acmaeodera Eschscholtz, 1829 (Coleoptera: Buprestidae) from southern Nevada, USA
(2023)
A new species of Acmaeodera Eschscholtz, 1829, A. raschkoi Westcott (Coleoptera: Buprestidae), is described from southern Nevada, USA, and compared to four other species in the genus. Its habitat and means of capture are discussed in detail.

A new species of the genus Bomansius Lacroix (Coleoptera: Lucanidae), which had been illustrated in the literature but never formally named, is described from Aneityum Island, Vanuatu (former New Hebrides) under the name of Bomansius cheesmanae Kakinuma, new species. The generic redescription of Bomansius and the redescription of B. gabrieli Lacroix, 1978 are also given based on additional specimens. Bomansius is transferred to tribe Aegini Huang and Chen, 2013.
The finding of Breviconia andrei sp. nov. in the Russian Bering Sea enabled the clear-cut phylogenetic characterization of the former monotypic genus Breviconia Conroy-Dalton & Huys, 2000 as a monophylum. Comparison of the new species with B. australis (George, 1998) and other members of the subfamily Ancorabolinae Sars, 1909 yielded four autapomorphies that unambiguously support the monophyletic state of Breviconia: (1) an elongated and approximately 90°-curved mandibular gnathobase, (2) reduction of the maxillar endopod, (3) maxillar endites carrying 2 instead of 3 setae, and (4) loss of the minute seta on the maxillipedal claw. For B. andrei sp. nov., two autapomorphies could be detected, namely, (1) the development of dorsal tubercles on the P5-bearing body somite and (2) the remarkable elongation of the first endopodal segment of the first swimming leg that is twice as long as the whole exopod. Of particular interest is the presence of a 3-segmented endopod in the third swimming leg of the male of B. andrei sp. nov. It disproves the current assumption that the Ancorabolinae are characterized by (among others) the derived presence of an only 2-segmented endopod in the male’s third swimming leg.
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.
A new species of Charinus is described from Israel and new localities for C. ioanniticus are reported. Charinus israelensis sp. nov. is a cave dwelling species with extremely small median eyes, no median tubercle and reduced lateral eyes. It is similar to C. ioanniticus, which occurs in nearby areas, but can be differentiated by the shape of the carapace, the number of pedipalp spines and the development of the eyes. A detailed comparison is made between the two species, including pictures, drawings and scanning electron micrographs. Charinus ioanniticus is reported here from several new localities in Israel and Turkey. Identification keys to the Charinus species groups and to the species of the bengalensis group are provided.
Crioprosopus baldwini Eya (Coleoptera: Cerambycidae: Cerambycinae: Trachyderini), sp. nov., from Costa Rica and Panama, is described. An amendment to the key to species of Crioprosopus Audinet-Serville, 1834, as presented in Eya (2015), is provided along with illustrations of the key characteristics to differentiate C. baldwini from other species.
Dipropus tequesta Johnson new species (Coleoptera: Elateridae) is described from southern Florida. Dipropus fuscus (LeConte) is a new synonym of D. soleatus (Say), and D. granosus (Fall) is a new synonym of D. asper (LeConte). The fl ightless female of D. asper is described and provides the fi rst report of brachyptery and endogean habits in Dipropus. A key to the species of the eastern United States and a new checklist of species for the country are provided.
Seven species of Drapetes Megerle (Coleoptera: Elateridae) are recognized from northern North America. Drapetes chiricahua new species is described from southeastern Arizona and north-central New Mexico. Drapetes parallelus Van Dyke is a senior homonym of Drapetes paralellus Cobos by variant spelling, and a new synonym of Drapetes cylindricus Fall. Drapetes paralellus Cobos is replaced with Drapetes cobosi new name. Drapetes clarki Bonvouloir is not a North American species and is given a redesignated type locality in Brazil. Drapetes plagiatus (Boheman) is not a California species and is given a redesignated type locality in Panama. New state records are reported for Drapetes exstriatus (Say) from Arkansas, Colorado, Nebraska, and Oklahoma. A key to the species of the region is provided and each species is illustrated.
Knowledge about the taxonomy and distribution of the monogeneric polychaete family Longosomatidae Hartman, 1944 is limited in all parts of the world. A new species of the genus Heterospio Ehlers, 1874 (Annelida, Longosomatidae) is described from the Indian Ocean. Heterospio indica sp. nov. is mainly characterised by the conspicuous flattening of the distal half of capillary chaetae located in anterior elongated segments. Several body characters of high taxonomic relevance in the genus are examined under the SEM and discussed. The 18S SSU rDNA and COI genes were sequenced and represent the first sequencing of a species of Heterospio, and the sequences have been deposited in GenBank.
Macrostemum is the second largest genus of Macronematinae with about 104 described species distributed in the Neotropical (18), Afrotropical (20), Australasian (7), Palearctic (2), Nearctic (3) and Oriental (54) regions. Despite its great diversity, knowledge about its immature stages is scarce: worldwide, only 7 species (6.7%) have larvae and/or pupae described. From the Neotropics, only one species, Macrostemum ulmeri (Banks, 1913), has described larvae and pupae. The objectives of this study are to describe and illustrate a new species, Macrostemum araca sp. nov., based on adult males and females from Serra do Aracá, Amazonas, Brazil, and the larvae and pupae of M. brasiliense (Fischer, 1970) from an Atlantic Forest fragment in São Paulo state using the metamorphotype method. In addition, this species is recorded for the first time for Minas Gerais state.
Metafruticicola is a diverse land snail genus inhabiting the north-eastern Mediterranean region from S Albania to Israel. In this study, we describe Metafruticicola kavafis sp. nov., a new species for science from Kasos Island. We also focus on the reproductive system of steno-endemic species and subspecies of the genus from small islands of the Aegean Archipelago, whose anatomy was previously completely unknown. These species are M. crassicosta, M. pieperi, M. coartata gemina and M. nicosiana conciliatrix. For the latter subspecies, only the outlines of the genitalia were previously given. Additionally, we investigated in detail for the first time the genital anatomy of M. nicosiana nicosiana from Cyprus. Hitherto, information on the genital apparatus of this subspecies was based on sparse data derived from sexually immature specimens. These new anatomical data contribute to a plethora of controversies concerning the subgeneric division of Metafruticicola, which was based solely on conchological features and especially the microsculpture of the teleoconch. We suggest that the current subgeneric division of the genus should be abandoned.
We describe a new species of Theloderma from northeastern Vietnam based on morphological differences and molecular divergence. Theloderma khoii sp. nov. is distinguishable from its congeners on the basis of a combination of the following characters: large size, SVL 52.1 mm in male, 59.4 mm in female; head length and width equal; vomerine teeth present; snout pointed and truncated, eye large, ED 4.7 mm in male, 5.6 mm in female, spinules on upper eyelid; tibiotarsal articulation reaches to the posterior border of the eye or the tip of the snout; dorsal skin very rough with large irregular gland ridges and warts, ventral surface of body granular; tips of all digits dilated but all considerably smaller than tympanum; dorsal surface mossy green or olive mottled with dark magenta. The distribution of the new species is unknown but probably extends into adjacent high elevation forested areas in Ha Giang Province, Vietnam and in Yunnan Province, China with an extent of occurrence of only < 1000 km2 and continuing decline in the quality of its habitat due to deforestation. Thus, we suggest the species should be considered Endangered following IUCN’s Red List categories.
A new species of vermetid gastropod belonging to the genus Novastoa Finlay, 1926, N. rapaitiensis sp. nov., is described from French Polynesia and the Great Barrier Reef, based on morpho-anatomical and molecular data, increasing the recognized extant diversity of this genus from five to six species. The new species is characterized by the largest operculum in the genus to date, with a conspicuous spindle-shaped mammilla that readily distinguishes this species from its congeners. Based on available data, members of the studied populations of N. rapaitiensis sp. nov. are interpreted as a single species, although slight morphological and color differences exist between localities separated by up to 7000 km. The larval development of N. rapaitiensis sp. nov. is inferred to be direct, raising new questions about genetic connectivity and dispersal trajectories across a vast geographic range. Additional molecular data may prove helpful in refining our current knowledge on the morphological variability within this species and verifying the degree of cryptic diversity in this genus.
Nerillids are small marine annelids, once placed at the artificial group ‘Archiannelida’, which contained all families of the exclusively interstitial polychaetes. Nerillidae is the most species rich family among them, with 71 species grouped into 15 genera, and represents an important component of the interstitial fauna, occupying a wide bathymetric range. Despite its problematic placement among the ‘Archiannelida’ families, the group per se is considered monophyletic. Currently, only two species of Paranerilla are valid, both being reported from the northern hemisphere. It is presented herein as the first description of a species of Paranerilla from tropical waters, named as Paranerilla schiavettii sp. nov., which is also considered as a unique record by the presence of a modified acicular spine in noto- and neuropodia from chaetiger 3–7, not mentioned in its congeners descriptions. Hence, we also propose an emendation on the genus diagnosis to embrace the presence of acicular spines within Paranerilla. So, the presented information complements the current knowledge about the group’s taxonomy and expands its distribution to South Atlantic waters.
A new species of tortoise beetle from the north-central United States, Parorectis arenaria new species (Coleoptera: Chrysomelidae: Cassidinae: Cassidini), is described and illustrated. Comparative remarks and a key are provided to distinguish the new species from the three other species comprising the genus. Adults and larvae of the new species feed on Physalis L. (Solanaceae). The circum-foraminal ridge and antennal groove of the prothorax are described in detail. The pars stridens (file) of the stridulatory apparatus on the male cranium of the new species is illustrated. The pars stridens is present only in males of Parorectis Spaeth species. A patch of spicules is located centrally on the dorsal surface of the cranium in both males and females of Parorectis. The spicule patch is believed to function as a head-to-body binding patch.
A new species of leaf insect from the celebicum species group, Phyllium (Phyllium) yapicum Cumming and Teemsma, new species (Phasmida: Phylliidae), is described from a female specimen from the California Academy of Sciences collection, United States. This new species is the first recorded species of Phylliidae from the country of Micronesia and represents a notable range expansion for the family. With Phyllium (Phyllium) yapicum Cumming and Teemsma, new species, currently only known from a female holotype; a key to females is included for the celebicum species group.
Pteroplatus antonkozlovi Santos-Silva and Botero, sp. nov. (Coleoptera: Cerambycidae) is described from Panama. Neocompsa thelgema Martins,1971 is recorded from Panama, and chromatic variation is discussed.The female of Icimauna aysa Martins and Galileo,1991 is described. Some corrections in a recently published work on Acanthoderini are provided, and the combination Scythropopsis pupillata (Bates,1880) is established as having precedence over the simultaneously published combination Aegomorphus pupillatus (Bates,1880).
A new species of snail-eating snakes of the genus Pareas Wagler, 1830 is described from the eastern Himalayas. The species Pareas kaduri sp. nov. differs from all known species of the genus in bearing the following suite of characters: SVL 455–550 mm, TaL/TL 0.184–0.207, brown dorsum with black transverse bands throughout the body, 15 dorsal scale rows throughout the body and mid-dorsal vertebral scale rows enlarged, 8 rows keeled in males, loreal not touching orbit, ventrals 160–183, subcaudals 65–70 in males, 52 in one female specimen, hemipenis short, unilobed and 6–7 maxillary teeth. Molecular data for mitochondrial 16S rRNA and cytochrome b genes further attest the distinctness of the new species, which was recovered as a member of the Pareas hamptoni clade. Our work brings the total number of species recognized within the genus Pareas to 20.
A new species of Strepsiptera of the genus Paraxenos Saunders, 1872 (Xenidae) from the United Arab Emirates is described. It was recorded from the host species Bembix kohli Morice, 1897 and represents the first occurrence of Paraxenos from Bembix Fabricius, 1775 in the Afrotropical region. A detailed redescription of the female cephalothorax of Paraxenos hungaricus (Székessy, 1955) is provided, together with the first description of the male cephalotheca. The holotype of Paraxenos krombeini Kifune & Hirashima, 1987 was redescribed. Additionally, a key for parasites of Bembix among Paraxenos species is provided based on characters of the female cephalothorax and male cephalotheca. The distribution and conservation status of Paraxenos spp. on Bembix are also discussed.
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.
The Bolivian Oreodera pergeri Wappes and Santos-Silva (Coleoptera: Cerambycidae: Lamiinae) is described as new. Oreodera howdeni Monné and Fragoso, 1988 is newly recorded for the state of Chiapas in Mexico and for Belize, and the main differences between the sexes are reported. Other new records reported are: Oreodera boucheri Néouze and Tavakilian, 2010 for Peru; O. vulgata Monné and Fragoso, 1988 for Paraguarí Department in Paraguay; and O. stictica Monné and Fragoso, 1988 for Bolivia (Santa Cruz). Oreodera sororcula Martins and Monné, 1993 is illustrated, and notes on color, morphological variations, and correction in the published sex of a paratype provided.
A new spider genus (Araneae: Linyphiidae: Erigoninae) from a tropical montane cloud forest of Mexico
(2021)
A new genus and species of spider (Araneae, Linyphiidae, Erigoninae) from a tropical montane cloud forest of Mexico is described from both male and female specimens, Xim trenzado gen. et sp. nov. A phylogenetic parsimony analysis situates Xim gen. nov. as a distinct genus among the distal Erigoninae. Xim gen. nov. is sister to a clade including Ceratinopsis, Tutaibo and Sphecozone, but differs from those genera by having a high cymbium, large paracymbium, short straight embolus, male cheliceral stridulatory striae widely and evenly spaced, both sexes with a post-ocular lobe, male with two series of prolateral macrosetae on femur I, and the female by having strongly oblong, u-shaped spermathecae.
Lectotypes are designated for Acmaeodera amabilis Horn, 1878 and Acmaeodera disjuncta Fall, 1899 (Coleoptera: Buprestidae). The defining characters of Acmaeodera opacula LeConte, 1858 are compared with those of A. disjuncta Fall, 1899, as well as habitat and host plant. Acmaeodera disjuncta is synonymized with A. opacula. The distinguishing characters of congeners whose general appearance at times can resemble A. opacula are discussed, and a new state record for Mexico is provided for A. opacula.

A new species of Neostygarctus Grimaldi de Zio et al., 1982 is described from the Great Meteor Seamount summit plateau in the Northeast Atlantic. Neostygarctus grossmeteori sp. nov. is characterized by the number and position of dorsomedian spines (five spines on the cephalic plate and each body plate and on the caudal plate, the spines decreasing in length backwards); the presence of eyes and of one or two pairs of ventral cervical spines; a transversal row of two to five short but strong spikes on the ventral side of the lateral body processes; only the internal claws of each leg provided with a normal accessory spine. The new species is related to N. acanthophorus Grimaldi de Zio et al., 1982 but differs by details of the dorsal body spines and the sculptures, the presence of ventral neck spines and ventral spikes on lateral body projections. Neostygarctus grossmeteori sp. nov. differs from two other known species of Neostygarctus, N. oceanopolis Kristensen et al., 2015 (Condor Seamont, NE Atlantic) and N. lovedeluxe Fujimoto & Miyazaki, 2013 (submarine cave NW Pacific), even more obviously by the number and position of dorsal body spines.
This paper describes a novel species of the genus Heterophoxus Shoemaker, 1925 from Brazil. The material examined was collected during the Mini Biological Trawl Project, off southeast and southern Brazil's coast off the states of Rio de Janeiro, Santa Catarina, and Rio Grande do Sul, ranging in depth from 25 to 128 meters. The new species, H. shoemakeri sp. nov., is similar to H. videns K.H. Barnard, 1930; however, the former species can be distinguished by: pereopod 7 basis posterior margin serrate with acute teeth, merus posterior margin not produced; epimeral plate 3 posteroventral corner with a longer acute projection, posterior margin almost straight; uropod 3 outer ramus article 2 clearly notable in both sexes. For Brazilian waters, this is the second record of the genus and the first species described with type material from the country. Besides that, we provide an identification key for the world species of Heterophoxus and a distribution map for the new species.
