Hemipogon s. str. (Apocynaceae: Asclepiadoideae) currently consists of three species sharing an erect herbaceous habit, narrow leaves and corona-less flowers with urceolate, internally bearded corolla, that are mainly distributed in savannahs of the Cerrado biodiversity hotspot, South America. Here, we describe and illustrate a new species of Hemipogon, H. trilobatus Bitencourt & Rapini sp. nov., from an open savannah in Chapada dos Veadeiros, Central Brazil. Hemipogon trilobatus sp. nov. differs from the other species of the genus mainly by the presence of a reduced staminal corona with 3-lobed lobes, but also by opposite leaves and triangular anthers. Distribution and habitat data, as well as a key and a comparative table to distinguish the four species currently accepted in Hemipogon s. str., are provided. Based on criteria B2ab(i,ii,iii,iv) of the International Union for Conservation of Nature (IUCN), the species is provisionally assessed as Critically Endangered.
Campodeinae is the most diverse subfamily of Campodeidae diplurans and inhabits soils and subsurface ecosystems. These are distributed in the Palearctic area, clearly rarifying towards northern latitudes. The major taxonomic characters are chaetotaxy, shape and complexity of pretarsal structures, and secondary sexual characters. This monograph provides a taxonomic revision of the subfamily Campodeinae in the Euro-Mediterrnean region, based on extensive literature review and new material studied. It comprises detailed morphological descriptions and illustrations together with habitat and distribution data of 161 species and 14 subspecies from 10 genera: Campodea Westwood, 1842, Edriocampa Silvestri, 1933, Eutrichocampa Silvestri, 1902, Helladocampa Condé, 1984, Libanocampa Condé, 1955, Litocampa Silvestri, 1933, Oreocampa Condé, 1950, Podocampa Silvestri, 1932, Remycampa Condé 1952, and Spaniocampa Silvestri, 1933. With 116 species Campodea is the most diverse and widely distributed genus in the studied area.
The present study evaluates the significance of Triassic ostracods from the Romanian Black Sea shelf as part of a project for the understanding of the palaeoceanographical evolution of the offshore extension of the North Dobrogean Orogen. The drill core CM31, sampled from the borehole 817 Lebăda Vest drilled on the western Romanian portion of the Black Sea shelf, contains sediments of Rhaetian, Late Triassic age. The taxonomy of ostracods obtained is discussed and adds to the scientific understanding of marine ostracods during the Rhaetian stage. We document 72 species, of which seven are new: Histriabairdia pontuseuxinusensis Forel gen. et sp. nov., Bairdiacypris argonautaii Forel sp. nov., Ceratobairdia? akhilleusi Forel sp. nov., Isobythocypris atalantella Forel sp. nov., Petasobairdia amazonella Forel sp. nov., Paracypris ovidi Forel sp. nov. and Pseudomacrocypris? kerabani Forel sp. nov. Histriabairdia Forel gen. nov. is introduced to accommodate species of the Triassic–Jurassic interval previously attributed to the modern genus Anchistrocheles. These assemblages point to an outer shelf environmental with relatively normal marine oxygenation. The oldest occurrence of Pokornyopsis, found in this material, indicates that this forerunner of modern troglobitic ostracods may not have been troglobitic in the Triassic.

Several taxa of Stephanodiscaceae were found in the upper section of Pleistocene sediments from Lake Petén-Itzá (Guatemala). A new fossil genus Cyclocostis Paillès gen. nov. and new extant species Discostella gabinii Paillès & Sylvestre sp. nov. are described. Cyclocostis gen. nov. is characterized by a strongly tangentially undulated valve surface, coarse unequal striation reaching a central punctum in the valve center, an absence of central lamina and domed criba, widely open alveoli with one median recessed costa bearing marginal fultoportulae and a single rimoportula all within a ring. A single valve face fultoportula is present on the raised part of the valve opposite the rimoportula. Differences relative to similar genera and the delimitation of a new genus are discussed. Discostella gabinii sp. nov. is distinguished by circular and flat valves, a small central area bearing 5 to > 30 scattered large areolae giving a colliculate appearance, medium-sized alveoli, marginal fultoportulae on every 4–5th costa, a single rimoportula and internally smooth valve center. Differences to similar taxa in the genus Discostella are discussed. The succession of the species of Cyclotella, Discostella and Cyclocostis gen. nov. in our record could represent eco-phenotypic responses to particular environmental stress / change.
Sweat bees in the subgenus Lasioglossum (Dialictus) are one of the most diverse and abundant bee taxa, and a critically important component of bee biodiversity. Yet, the most basic taxonomic knowledge of these bees is lacking in many regions. As a step towards a better understanding of the L. (Dialictus) of the western Nearctic region, a revision of the ‘red-tailed’ L. (Dialictus) species was completed. Thirty-six species were revised, 20 of which are described as new, and two names are treated as junior subjective synonyms. Descriptions, figures, distribution maps, floral hosts, and keys to species for females and males are provided. The following 20 species are described as new: Lasioglossum (Dialictus) arenisaltans sp. nov., L. (D.) argammon sp. nov., L. (D.) austerum sp. nov., L. (D.) cactorum sp. nov., L. (D.) cembrilacus sp. nov., L. (D.) clastipedion sp. nov., L. (D.) clavicorne sp. nov., L. (D.) decorum sp. nov., L. (D.) festinum sp. nov., L. (D.) imbriumbrae sp. nov., L. (D.) julipile sp. nov., L. (D.) lilianae sp. nov., L. (D.) meteorum sp. nov., L. (D.) miltolepoides sp. nov., L. (D.) minckleyi sp. nov., L. (D.) perditum sp. nov., L. (D.) rufornatum sp. nov., L. (D. ) spivakae sp. nov., L. (D.) tessellatosum sp. nov., and L. (D.) torrens sp. nov. Previously unknown males of L. (D.) clematisellum (Cockerell, 1904), L. (D.) droegei Gibbs, 2009, L. (D.) kunzei (Cockerell, 1898), and L. (D.) pallidellum (Ellis, 1914) are described and figured for the first time. Lasioglossum (Dialictus) clarissimum (Ellis, 1914) (= Halictus clarissimus Ellis, 1914) and L. (D.) perexiguum (Sandhouse, 1924) (= Halictus (Chloralictus) perexiguus Sandhouse, 1924) are new subjective junior synonyms of L. mesillense (Cockerell, 1898) (= Halictus nymphalis var. mesillensis Cockerell, 1898). A lectotype specimen is newly designated for L. mesillense, for which the location of the type material has not previously been known. The following five new records for Mexico are reported: L. clematisellum, L. droegei, L. eophilus (Ellis, 1914), L. kunzei, and L. pallidellum.

Im Fachbereich Literaturwissenschaft beschäftigt sich der erste Artikel mit dem Begriff der "neuen Weiblichkeit" und unternimmt einen Vergleich zwischen dem Werk von Halide Edip Adıvar "Ateşten Gömlek" (1922) [dt. Das Flammenhemd] und dem Werk von David Herbert Lawrence "The Fox" (1922) [dt. Der Fuchs]. Der zweite Beitrag bearbeitet die sogenannte Schäferkultur. In ihrem Artikel erwähnt die Autorin wichtige Auswirkungen des Geographie- und Glaubenssystems auf die Menschen und den Schäferberuf, welcher einer der ältesten Berufe ist und angesichts dieser Einflüsse entstand. Im dritten Beitrag handelt es sich um die Reiseberichte des deutschen Orientalisten und Reisenden Eduard Sachau (1845-1930). Der Autor geht davon aus, dass Sachaus Reise ein Prozess der orientalistischen Wissensproduktion war und er diese Informationen, die er während seiner Reise gesammelt hat, auf unterschiedliche Weise in akademische Texte umgesetzt hat. Der vierte Beitrag setzt sich zum Ziel, die merkmalspezifischen Handlungsweisen von Vater und Sohn in ausgewählten Geschichten des Romans "Als Vaters Bart noch rot war - Ein Roman in Geschichten" unter pädagogischem Gesichtspunkt zu untersuchen. In der fünften Studie wird die Sichtweise von Frauen, Frauenbildern, verschiedenen weiblichen Rollen in der deutschen und türkischen Gesellschaft im Roman 'Die Brücke vom goldenen Horn' von Emine Sevgi Özdamar analysiert. Es wird beabsichtigt, aus dem Blickwinkel einer Schriftstellerin aufzuzeigen, wie sich die Frauenbilder in den Jahren 1966-1975 in Deutschland und in der Türkei darstellten, ob es Unterschiede zwischen den zwei Kulturen gab und vor welchem geschichtlichen und sozialen Hintergrund die Frau, die im Mittelpunkt steht, lebte. Der sechste Beitrag thematisiert die Lacansche Psychoanalyse und untersucht die drei Perioden (real, imaginär und symbolisch) des psychischen Subjekts. Nach diesen theoretischen Kenntnissen wird das Vogelbild in der Kurzgeschichte "Vogel Rock" von Marie Luise Kaschnitz im Lichte der Informationen der Lacanischen Psychoanalyse untersucht. Die Autorin versucht, die Projektionen der Prozesse der Verfremdung zu behandeln. Der letzte Aufsatz dieser Kategorie möchte die Reiseberichte der Schweizer Journalistin, Reporterin, Autorin und Fotografin Annemarie Schwarzenbach, die im Oktober 1933 eine Mission als Journalistin in den Orient aufnahm, in den Blickpunkt stellen. Die Autorin bezweckt dabei zum Verständnis des Türkenbildes einen Beitrag zu leisten, welches Schwarzenbach in der deutschen Literatur vertritt. [...]
Diese Ausgabe des "Forums Interdisziplinäre Begriffsgeschichte" vereint zwei Themenschwerpunkte, die, unabhängig voneinander entstanden, auch inhaltlich zunächst nichts miteinander zu tun zu haben scheinen. In drei englischsprachigen Beiträgen des ersten Teils geht es um die sich semantisch und in ihrer historischen Genese überlappenden Begriffe 'Energie', 'Entropie' und 'Anthropozän'. Der zweite Themenschwerpunkt behandelt begriffshistorische Verschiebungen im Theoriegebäude der Sprachwissenschaft. Die Ausgabe wird beschlossen durch den Politikwissenschaftler Kari Palonen (Universität Jyväskylä, Finnland), der einen Band zur Geschichte der politischen Ideengeschichte rezensiert.

A new giant species of the subfamily Rhynchoproctinae with strikingly bi-coloured, red-yellow legs contrasting with a black body is described: Alienostreptus bicoloripes sp. nov. from Vietnam. The new species is assigned to the genus Alienostreptus Pimvichai, Enghoff & Panha, 2010 hitherto comprising one species, A. alienus (Attems, 1936), and differing from other rhynchoproctine genera by having the femoral spine duplicated. Species of this genus share three synapomorphic characters of the subfamily, viz (1) anterior coxal fold forms deep concavity in posterior view, (2) posterior coxal fold very low, and (3) posterior coxal fold with mesal flap. A superficially very similar colourful species from Borneo, also with bi-coloured legs but clearly not belonging to Alienostreptus due to the position of ventral soft pads on male legs, is documented based on photographs.
Features of the Maechidiini (Scarabaeidae: Melolonthinae) genera Maechidius Macleay, 1819, Epholcis Waterhouse, 1875 and Paramaechidius Frey, 1969 are critically revised and a new synonymy is proposed: Maechidius = Epholcis syn. nov. = Paramaechidius syn. nov. A key to and an annotated checklist of Maechidiini from the Indo-Australian transition zone are presented for the first time. Thirty-five new species are described, namely Maechidius aiyura sp. nov., M. alesbezdeki sp. nov., M. awu sp. nov., M. babyrousa sp. nov., M. bintang sp. nov., M. boessnecki sp. nov., M. brocki sp. nov., M. caperatus sp. nov., M. ciliatus sp. nov., M. crypticus sp. nov., M. dani sp. nov., M. deltouri sp. nov., M. dendrolagus sp. nov., M. hamatus sp. nov., M. kazantsevi sp. nov., M. konjo sp. nov., M. lapsus sp. nov., M. legalovi sp. nov., M. leucopsar sp. nov., M. longipes sp. nov., M. mailu sp. nov., M. maleo sp. nov., M. merdeka sp. nov., M. miklouhomaclayi sp. nov., M. nepenthephilus sp. nov., M. owenstanleyi sp. nov., M. riedeli sp. nov., M. similis sp. nov., M. skalei sp. nov., M. sougb sp. nov., M. suwawa sp. nov., M. trivialis sp. nov., M. ursus sp. nov., M. weigeli sp. nov. and M. yamdena sp. nov. Six new synonyms are proposed: Maechidius Macleay, 1819 = Epholcis Waterhouse, 1875 syn. nov. = Paramaechidius Frey, 1969 syn. nov., Maechidius esau Heller, 1914 = M. setosus Moser, 1920 syn. nov. = M. setosellus Frey, 1969 syn. nov., Maechidius heterosquamosus Heller, 1910 comb. rest. = Paramaechidius clypeatus Frey, 1969 syn. nov. and Maechidius paupianus Heller, 1910 = M. arrowi Frey, 1969 syn. nov. The first records of Maechidiini from the Tanimbar Islands (Yamdena), Sangihe Islands (Sangir) and Lesser Sunda Islands (Bali) are documented, of which the latter two are the northern- and westernmost known records of Maechidius and of the tribe Maechidiini. Lectotypes are designated for 23 species. Fifteen new combinations are proposed and the original combination to Maechidius is restored for four species. Ecological data are presented for the first time for selected Papuan and Wallacean species. Type material of Wallacean and Papuan Maechidiini is depicted for the first time. A key to species is given. In total, 78 species of Maechidiini are confirmed for the Indo-Australian transition zone.

Sea pens (Cnidaria: Anthozoa: Pennatulacea) constitute a distinctive group of colonial marine invertebrates. They inhabit the world`s oceans, from shallow to deep waters. Studies about this group in Argentina are scarce, and no species have been described in the area in over a decade. Based on samples collected in Mar del Plata Submarine Canyon at about 3000 m deep we describe a new species of sea pen, Umbellula pomona Risaro, Williams & Lauretta sp. nov. This is a spiculate Umbellula that differs from other species of Umbellula with sclerites, by the number, development and distribution of the autozooids in its terminal cluster, as well as the shape of its axis. Molecular data also distinguishes it from other known species. Of the forty-three described species approximately ten are considered valid for the genus Umbellula, four of them are registered for the South Atlantic Ocean and only three are described for the Antarctic region. Since sampling efforts in this area have been scarce, the number of species of sea pens from the region is likely to increase substantially in the coming years.
Dichromatobolus, a new genus of spirobolidan millipedes from Madagascar (Spirobolida, Pachybolidae)
(2020)
A new genus, Dichromatobolus gen. nov., belonging to the genus-rich mainly southern hemisphere family Pachybolidae of the order Spirobolida, is described based on D. elephantulus gen. et sp. nov., illustrated with color pictures, line drawings, and scanning electron micrographs. The species is recorded from the spiny bush of southwestern Madagascar. Dichromatobolus elephantulus gen. et sp. nov. shows an unusual color pattern, sexual dichromatism with males being red with black legs and females being grey. Males seem to be more surface active, as mainly males were collected with pitfall traps. Females mainly come from the pet trade. The body of this species is short and very wide, being only 8 times longer than wide in the males. Live observations show the species is a very slow mover, digging in loose soil almost as fast as walking on the surface. The posterior gonopods of Dichromatobolus gen. nov. are unusually simple and well-rounded, displaying some similarities to the genera Corallobolus Wesener, 2009 and Granitobolus Wesener, 2009, from which the new genus differs in numerous other characters, e.g., size, anterior gonopods and habitus. Despite several attempts with fresh tissue samples and different primers, molecular barcoding did not work for Dichromatobolus gen. nov. Any relationships to the other 15 genera of Pachybolidae indigenous to Madagascar remain unknown.
In this study, we examine 500 specimens of Anaplecta collected from China, of which 26 samples were used for COI sequencing. We confirm eight new species, i.e., Anaplecta corneola Deng & Che sp. nov., Anaplecta staminiformis Deng & Che sp. nov., Anaplecta arcuata Deng & Che sp. nov., Anaplecta strigata Deng & Che sp. nov., Anaplecta furcata Deng & Che sp. nov., Anaplecta cruciata Deng & Che sp. nov., Anaplecta nigra Deng & Che sp. nov. and Anaplecta bicolor Deng & Che sp. nov. based on morphological and molecular data using ABGD and GMYC analyses. The results of ABGD and GMYC were basically consistent with the morphospecies of Anaplecta. The intraspecific and interspecific genetic distances of Anaplecta ranged from 0 to 6.6% and 16.8% to 31.8%, respectively. We found the male genitalia of Anaplecta to exhibit intraspecific variation, especially in the phallomeres.
An inventory of Sciaridae (Diptera: Sciaroidea) from a eutrophic fen and a spring brook in Viidumäe Nature Reserve (Estonia, Saaremaa Island) recorded a total of 60 species, of which 57 are new records for Estonia, including two that are new to science and described herein as Cratyna (Diversicratyna) palustricola sp. nov. (Estonia) and Sciara bryophila sp. nov. (Estonia, Finland). This has raised the number of Sciaridae known from Estonia from 6 to 63.
All extant species of the planthopper genus Limois Stål (Hemiptera: Fulgoromorpha: Fulgoridae) were studied. One new species, Limois sordida sp. nov., is described and illustrated from China. Six known species are re-described and photos and illustrations of male genitalia are provided. A key to all extant species of this genus is also given.
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.
We review the species of Bidessus of Madagascar and describe Bidessus anjozorobe sp. nov. from material collected in Anjozorobe forest. Anjozorobe is part of the Anjozorobe-Angavo Protected Area, which is an important corridor of transition forest between typical eastern humid forests and the residual sub-humid forest of the Central Highlands. Bidessus longistriga Régimbart, 1895 and Bidessus perexiguus Kolbe, 1883 are widespread but endemic low-altitude species on Madagascar. Bidessus nesioticus Guignot, 1956 is an alpine species described from near the peak of the Ankaratra mountain massifs at 2500 m a.s.l. We recollected the species for the first time since its description, in Ankaratra and in a new area above 2000 m a.s.l. in the Andringitra mountain further south. Bidessus cf. nero Gschwendtner, 1933 is tentatively recorded for Madagascar for the first time but further studies are needed to test the status of mainland and insular populations. Bidessus apicidens Biström & Sanfilippo, 1986 has not been recollected on Madagascar since 1970. All species are endemic to Madagascar except potentially Bidessus cf. ceratus and Bidessus cf. nero described from Uganda and the Democratic Republic of the Congo, respectively. The older records of the two non-endemic species Bidessus complicatus Sharp, 1904 and Bidessus ovoideus Régimbart, 1895 on Madagascar could not be verified.
Species are often presumed to be apparent in nature, but in practice they may be difficult to recognise, especially when viewed across continents rather than within a single site. Coalescent-based Poisson-tree-process (PTP) models applied to fast-evolving genes promise one quantitative criterion for recognising species, complete with the estimates of uncertainty that are required of a scientific method. Such methods face challenges especially in discerning between widespread polytypic species and complexes of closely related, restricted-range species. In particular, ‘over-sampling’ of many closely related individuals within one species could risk causing groups of less closely-related individuals within other species appearing relatively more distinct and consequently could risk them being interpreted falsely as separate species. Some of the most persistent taxonomic problems among bumblebees (genus Bombus Latreille, 1802) are within the subgenus Melanobombus von Dalla Torre, 1880. For a global revision of Melanobombus species, we use COI barcodes and seek to reduce the risk from localised over-sampling by filtering the data to include only unique haplotypes. Unique haplotypes give more conservative results than unfiltered data, but still increase the number of species in comparison with recent morphological treatments. After integrative assessment of COI coalescents in comparison with morphological groups, the number of accepted species shows a non-linear increase with sample size that plateaus to an increase of 47% (to 25 species) compared with a previous estimate (of 17) based on morphology alone. For the most widespread and variable species-complexes, our revised species improve the match to the patterns expected of species, both for genetic divergence-with-distance and for sympatry, leading to three main inferences. (1) The particularly widespread polytypic Bombus sichelii Radoszkowski, 1859, is a single species. (2) We detect two candidates for species within previous broad concepts of each of the former B. lapidarius (Linnaeus, 1758), B. miniatus Bingham, 1897, and B. rufofasciatus Smith, 1852. Within B. lapidarius s. lat. we find insufficient evidence to corroborate the candidate species, with no coalescent or morphological support for a recent claim for a separate species, B. bisiculus Lecocq, Biella, Martinet & Rasmont, 2019 described from southern Italy, but rather we find a weak and uncorroborated coalescent for a different and much broader group of samples from across southeastern Europe but excluding Turkey. Within the former broad concepts of B. miniatus s. lat. and B. rufofasciatus s. lat. the coalescent evidence is stronger and subtle evidence from morphology corroborates recognising B. miniatus s. str. and B. eurythorax Wang, 1892 stat. rev. as separate species as well as B. rufofasciatus s. str. and B. prshewalskyi Morawitz, 1880 stat. rev. as separate species. (3) Our coalescent and morphological results ‘split’ more clearly what has long been interpreted as a single polytypic B. keriensis Morawitz, 1887, s. lat., by supporting novel concepts of the restricted-range species: B. alagesianus Reinig, 1930 stat. rev., B. incertoides Vogt, 1911 stat. rev., B. keriensis s. str., B. qilianensis sp. nov., B. separandus Vogt, 1909 stat. rev., and B. tibeticus sp. nov. A lectotype is designated for the name B. keriensis and a neotype is designated for the name B. alagesianus. We estimate the phylogeny of Melanobombus species by including three slower-evolving genes to provide more evidence for deeper relationships, to estimate the time calibration of this phylogeny, and to estimate ancestral distributions, all within a Bayesian framework. We provide the first keys for identifying all of the species of Melanobombus.
We present a comprehensive revision of the pholcid spider collection of M.A. González-Sponga, who between 1998 and 2011 described 22 new genera and 51 new species of Pholcidae from Venezuela. In addition, we treat the pholcid material collected during three expeditions to Venezuela conducted between 2002 and 2020. Of González-Sponga’s pholcid taxa we recognize three genera and 24 species as valid. We describe 43 new species (all from males and females) in one new and 13 previously described genera; four genera are newly recorded for Venezuela. We describe the previously unknown females of 15 species, present new records for 46 previously described species, synonymize one genus and one species, and correct numerous minor errors in previous publications on Venezuelan pholcids. At the generic level, the Venezuelan pholcid fauna now appears fairly well known, but available data on distribution and endemism suggest that many species remain undiscovered and undescribed. Despite the obvious gaps, our data are congruent with previous studies on other taxa that have the highest levels of endemism in the Venezuelan Andes, the Coastal Ranges, and the Guyana Highlands. The Falcón Region in particular shows a complex mosaic of biogeographic relationships with other regions. We provide new biological data on numerous species. We document the first cases of evolutionary microhabitat shifts in the genera Mecolaesthus Simon, 1893 and Priscula Simon, 1893. We document several cases of close congeners sharing localities, usually in slightly to conspicuously different microhabitats, sometimes apparently in identical microhabitats. We document several cases of color polymorphism, mostly intersexual, in Metagonia conica (Simon, 1893) both intersexual and among males. We document further cases of two rare phenomena in Pholcidae: use of specific non-silken structures for retreats (in Pisaboa Huber, 2000) and egg parasitism (in Priscula).

This paper treats the planthopper genus, Atracis Stål, 1866 (Flatidae: Flatoidinae) in China. Five new species, A. ocularia sp. nov., A. patefacta sp. nov., A. punctulata sp. nov., A. sphaerica sp. nov. and A. ungulata sp. nov., are described and a checklist of all its known species from China is provided.
Nemaspela Šilhavý, 1966 (Opiliones: Nemastomatidae) is a genus of exclusively troglobiotic harvestmen species inhabiting caves in the Crimea, Caucasus and Balkan Peninsula. In this paper, Nemaspela borkoae sp. nov., recently found in four caves in Montenegro, is described. The new species is characterized by its small body, 1.5–2.1 mm long, and very long, thin appendages, with legs II about 15 times as long as the body. Although very similar, Nemaspela ladae Karaman, 2013 and N. borkoae sp. nov. can be easily distinguished by the terminally rounded vs conical glans, straight vs conspicuously ventrally bent pedipalp tarsus on its proximal portion and pedipalp tarsus measuring about ½ vs ⅔ tibia length. Nemaspela ladae and N. borkoae sp. nov. constitute the western Nemaspela group, both missing the male cheliceral apophysis present in all species of the eastern Nemaspela group from the Crimea and Caucasus, except in N. femorecurvata Martens, 2006. However, according to the glans morphology, N. borkoae sp. nov. seems much more closely related to several species from the Caucasus than to N. ladae from the Balkan Peninsula. We speculate that N. ladae and N. borkoae sp. nov. might originate from two epigean ancestral lineages.
The genus Teloneria Aczél, 1954 is resurrected from synonymy with Chaetonerius Hendel, 1913 to include four species: Teloneria apicata (Edwards, 1919) comb. nov., Teloneria bimaculata (Edwards, 1919) comb. nov., Teloneria juceliae Sepúlveda & Souza sp. nov. and Teloneria ladyae Sepúlveda & Souza sp. nov. Lectotypes for Telostylus apicatus Edwards, 1919 and its junior synonym, Telostylinus apicalis Enderlein, 1922, and for Telostylinus ornatipennis Enderlein, 1922, junior synonym of Teloneria bimaculata comb. nov., are designated. An identification key to Chaetonerius, Telostylus Bigot, 1859 and Teloneria, with emphasis on the identification of the species of Teloneria, illustrations and distribution data are provided.
Five new species of Peltonotellini (Caliscelinae) are described and illustrated: Bruchomorpha pseudodorsata sp. nov., Fitchiella brachyrhina sp. nov., Protrocha nigrilutea sp. nov. and P. punctatosa sp. nov. from Mexico, and Fitchiella zahniseri sp. nov. from Panama. Additionally, five previously described species are redescribed based on newly collected specimens: Aphelonema brevata Caldwell, 1945 (proposed original combination), Bruchomorpha decorata Metcalf, 1923, Bruchomorpha mormo Kirkaldy, 1907, Nenema virgata (Doering, 1941) and Protrocha nesolitaria (Caldwell, 1945). Bruchomorpha decorata is recorded from Panama for the first time. Redescriptions provide new information on the distribution of sensory pits and the first detailed descriptions of male and female terminalia for these species.
