DOI: 10.3897/zookeys.1196.117921

Authors: Long Lin, Zhiyong Yang, Junxia Zhang

Abstract: The monotypic genus Cheliceroides Żabka, 1985 is revalidated based on both molecular sequence data (ultra-conserved elements and protein coding genes of mitochondrial genomes) and morphological evidence. Our molecular phylogenetic analyses show that Cheliceroides is not closely related to Colopsus Simon, 1902, not even in the same tribe, and a comparative morphological study also demonstrates significant differences in the genital structures (i.e. in the shape of embolus, and with or without pocket on epigynum) of the two genera. Therefore, we remove Cheliceroides from the synonymy of Colopsus, and its generic status is revalidated.

A new monotypic genus of cobweb spiders from the Russian Far East (Araneae, Theridiidae) https://zookeys.pensoft.net/article/118632/ ZooKeys 1195: 219-238

DOI: 10.3897/zookeys.1195.118632

Authors: Yuri M. Marusik, Kirill Y. Eskov

Abstract: A new theridiid spider, Knoflachia kurilensis gen. et sp. nov., is described from the Kuril Islands (Kunashir). The new genus belongs to the ‘Anelosimus clade (clade 24)’ of Agnarsson (2004). A pair of raised, fused setal sockets on the cheliceral promargin adjacent to the fang base was found to be another synapomorphy of all the ‘distal theridiids’ (the ‘elongated central claw clade (clade 33)’: argyrodins, ‘Anelosimus clade’ and theridiins). Knoflachia kurilensis sp. nov. demonstrates a male polymorphism similar to some Anelosimus Simon, 1891 species (e.g., A. studiosus (Hentz, 1850)).

Ghatippus paschima, a new species and genus of plexippine jumping spider from the Western Ghats of India (Salticidae, Plexippini, Plexippina) https://zookeys.pensoft.net/article/114117/ ZooKeys 1191: 89-103

DOI: 10.3897/zookeys.1191.114117

Authors: Kiran Marathe, Wayne P. Maddison, Krushnamegh Kunte

Abstract: We propose a new genus of plexippine jumping spiders from the Western Ghats of India based on the new species Ghatippus paschima gen. et sp. nov. While it bears a superficial resemblance to Pancorius in body form and Hyllus in membrane-bearing embolus, our UCE phylogenomic data—the first to resolve broad relationships within the Plexippina—as well as morphological features justify its status as a new genus. In addition to the molecular data and morphological descriptions, we provide photographs of living specimens of Ghatippus paschima gen. et sp. nov. and information on their natural history.

On Psalmopoeus Pocock, 1895 (Araneae, Theraphosidae) species and tarantula conservation in Ecuador https://zookeys.pensoft.net/article/108991/ ZooKeys 1186: 185-205

DOI: 10.3897/zookeys.1186.108991

Authors: Pedro Peñaherrera-R., Roberto J. León-E.

Abstract: Two novel species of Psalmopoeus Pocock, 1895 are described from the north-western and central-western slopes of the Cordillera Occidental of the Andes mountain range in Ecuador. The new species are easily differentiated from other congeners of Psalmopoeus by spermathecae and male palpal bulb morphology and a comparatively distant distribution to the type localities of the geographically nearest known congeners. The diagnosis of P. ecclesiasticus Pocock, 1093 is revised and updated, considering the novel species and observations on spermatheca of this species. Likewise, an evaluation is provided for the new species in terms of conservation due to the various threats impacting ecosystems and ecosystem services of their type localities. Finally, the importance of theraphosid spiders in Ecuador and South America and their possible conservation requirements are discussed and assessed.

Abstract: Species of wolf spiders considered in the Pardosa atrata group are surveyed, and comparative figures of all species included in the group are presented for the first time. A new species, P. armeniaca sp. nov., is described from the shore of Lake Sevan (Armenia) based on both sexes. Pardosa narymica Savelyeva, 1972 from East Kazakhstan Oblast’ is synonymized with the trans-Palaearctic P. atrata (Thorell, 1873). It was found that the record of P. atrata (sub P. lapponica) by Schenkel from British Columbia and reflected in the World Spider Catalog in fact refers to P. concinna (Thorell, 1877), a member of the P. lapponica group. The distribution of three species consideredin the atrata group are mapped. The discovery of P. armeniaca sp. nov. has led to a re-evaluation of the distribution range, previously thought to be continuous, now showing a disjunctive pattern.

Integrative taxonomic revision of the genera Nesticella and Howaia in Japan with the description of five new species (Araneae, Nesticidae, Nesticellini) https://zookeys.pensoft.net/article/101251/ ZooKeys 1174: 219-272

DOI: 10.3897/zookeys.1174.101251

Authors: Francesco Ballarin, Katsuyuki Eguchi

Abstract: The Japanese species of the genera Nesticella Lehtinen & Saaristo, 1980 and Howaia Lehtinen & Saaristo, 1980 (Araneae, Nesticidae, Nesticellini) are revised using an integrative taxonomic approach. Their morphology, phylogenetic position within the genera, assignment to species groups, and distribution in mainland Japan and the Ryukyu islands are discussed herein. A phylogenetic and species delimitation analysis was conducted to confirm the boundaries between the putative species that were initially discriminated based on external and genital morphology. As a result of the present study, six species of Nesticella and three species of Howaia are proposed for the fauna of Japan based on the combined results of morphology and molecular analyses. Male and female of the previously known species H. mogera (Yaginuma, 1972), N. brevipes (Yaginuma, 1970), and N. okinawaensis (Yaginuma, 1979) are redescribed and illustrated using type specimens or specimens collected at the type locality. Nesticella terrestris (Yaginuma, 1970) is resurrected as a valid species and distinguished from the closely related N. brevipes based on morphological and molecular evidence. The male of N. terrestris is described for the first time. We herein describe three new species of Nesticella and two new species of Howaia from different islands in the Ryukyu Archipelago, southwest Japan: N. insulana sp. nov. (♂, ♀) from Yonaguni-jima Island, N. occulta sp. nov. (♀) from Ishigaki-jima Island, N. silvicola sp. nov. (♂, ♀) from Yakushima Island, H. alba sp. nov. (♂, ♀) from Miyako-jima Island and H. subterranea sp. nov. (♀) from Okinoerabu-jima Island. Nesticella occulta sp. nov., H. alba sp. nov. and H. subterranea sp. nov. dwell exclusively in caves and show extensive morphological adaptation to subterranean life.

Species delimitation, biogeography, and natural history of dwarf funnel web spiders (Mygalomorphae, Hexurellidae, Hexurella) from the United States / Mexico borderlands https://zookeys.pensoft.net/article/103463/ ZooKeys 1167: 109-157

DOI: 10.3897/zookeys.1167.103463

Authors: Rodrigo Monjaraz-Ruedas, Raymond Wyatt Mendez, Marshal Hedin

Abstract: The rarely encountered spider genus Hexurella Gertsch & Platnick, 1979 includes some of the smallest mygalomorph spiders in the world, with four poorly known taxa from central and southeastern montane Arizona, southern California, and northern Baja California Norte. At time of description the genus was known from fewer than 20 individuals, with sparse natural history information suggesting a vagrant, web-building, litter-dwelling natural history. Here the first published taxonomic and natural history information for this taxon is provided in more than 50 years, working from extensive new geographic sampling, consideration of male and female morphology, and sequence capture-based nuclear phylogenomics and mitogenomics. Several new species are easily diagnosed based on distinctive male morphologies, while a complex of populations from central and northern Arizona required an integrative combination of genomic algorithmic species delimitation analyses and morphological study. Four new species are described, including H. ephedra sp. nov., H. uwiiltil sp. nov., H. xerica sp. nov., and H. zas sp. nov. Females of H. encina Gertsch & Platnick, 1979 are also described for the first time. It is predicted that additional new species will ultimately be found in the mountains of central and northwestern Arizona, northern mainland Mexico, and the Mojave Desert of California.

Four new species of mygalomorph spiders (Araneae, Halonoproctidae and Theraphosidae) from the Colombian Pacific region (Bahía Solano, Chocó) https://zookeys.pensoft.net/article/101069/ ZooKeys 1166: 49-90

DOI: 10.3897/zookeys.1166.101069

Authors: Mariana Echeverri, Sebastián Gómez Torres, Nicolás Pinel, Carlos Perafán

Abstract: The Colombian Pacific coast is an amazing natural region, immersed in one of the most unknown biodiversity hotspots in the world. An expedition carried out in the north of this area, at the Jardín Botánico del Pacífico (JBP) in Bahía Solano, Chocó, focused on studying the diversity of the mygalomorph spider fauna, allowed us to discover four new species included in the families Halonoproctidae and Theraphosidae. The trapdoor species Ummidia solana sp. nov., and the theraphosids species Euthycaelus cunampia sp. nov. (Schismatothelinae), Melloina pacifica sp. nov. (Glabropelmatinae), and Neischnocolus mecana sp. nov. (Theraphosinae) are illustrated, diagnosed, and described in detail. Photographs of somatic features and copulatory organs and a distribution map are provided. Morphological, taxonomical, and biogeographical aspects are discussed for each species. All these taxonomic novelties represent the first records of these genera for the region, expanding the range of geographic distribution of each of them. This work constitutes the first effort focused on characterizing the community of Mygalomorphae species in the Chocó Biogeographic Region.

DOI: 10.3897/zookeys.1146.97517

Authors: Alireza Zamani, Yuri M. Marusik, Tamás Szűts

Abstract: The taxonomy of the Iranian species of the dysderid spider genus Dysdera Latreille, 1804 is revised. Currently, the only species of this genus known from Iran is D. pococki Dunin, 1985, albeit on the basis of a doubtful record. The following 14 species are described as new to science in this paper: D. achaemenes sp. nov. (♀; Fars), D. bakhtiari sp. nov. (♂; Chaharmahal & Bakhtiari), D. damavandica sp. nov. (♂; Mazandaran), D. genoensis sp. nov. (♂♀; Hormozgan), D. hormuzensis sp. nov. (♀; Hormozgan), D. iranica sp. nov. (♂♀; Fars, Hormozgan), D. isfahanica sp. nov. (♂♀; Isfahan), D. mazeruni sp. nov. (♀; Mazandaran), D. medes sp. nov. (♂; Tehran), D. persica sp. nov. (♂♀; Golestan, Mazandaran), D. sagartia sp. nov. (♂♀; Tehran), D. tapuria sp. nov. (♂♀; Mazandaran), D. verkana sp. nov. (♂; Golestan), and D. xerxesi sp. nov. (♂; Bushehr). Distribution records of all species are mapped. Also, the taxonomy of Mistura Petrunkevitch, 1971 and Segistriites Straus, 1967, two fossil genera currently considered in Dysderidae, is discussed and the latter is transferred to Segestriidae.

New species in old mountains: integrative taxonomy reveals ten new species and extensive short-range endemism in Nesticus spiders (Araneae, Nesticidae) from the southern Appalachian Mountains https://zookeys.pensoft.net/article/96724/ ZooKeys 1145: 1-130

DOI: 10.3897/zookeys.1145.96724

Authors: Marshal Hedin, Marc A. Milne

Abstract: This revision is based on sampling efforts over the past three decades in the southern Appalachian Mountains which have provided Nesticus (Araneae, Nesticidae) collections of approximately 2100 adult specimens from more than 475 unique collecting events. Using a “morphology first” framework we examined recently collected specimens plus museum material to formulate morphology-based species hypotheses for putative new taxa (discovery phase). Using sequence capture of nuclear ultraconserved elements (UCEs) we analyzed 801 nuclear loci to validate new (and prior) morphology-based species hypotheses (validation phase) and reconstructed a robust backbone phylogeny including all described and new species. Sanger sequencing and UCE-bycatch were also used to gather mitochondrial data for more than 240 specimens. Based on our integrative taxonomic framework ten new Nesticus species are herein described, including N. binfordae sp. nov., N. bondi sp. nov., N. canei sp. nov., N. cherokeensis sp. nov., N. dellingeri sp. nov., N. dykemanae sp. nov., N. jemisinae sp. nov., N. lowderi sp. nov., N. roanensis sp. nov., and N. templetoni sp. nov. Previously unknown males are also described for N. bishopi Gertsch, 1984, N. crosbyi Gertsch, 1984, and N. silvanus Gertsch, 1984, as well as the previously unknown female for N. mimus Gertsch, 1984. Based on combined evidence N. cooperi Gertsch, 1984 is placed in synonymy with N. reclusus Gertsch, 1984. Overall, the montane radiation of Appalachian Nesticus reveals a general lack of species sympatry and compelling biogeographic patterns. Several regional Nesticus taxa are rare, microendemic habitat specialists that deserve conservation attention and detailed future monitoring as conservation sentinels.

To be or not to be… Integrative taxonomy and species delimitation in the daddy long-legs spiders of the genus Physocyclus (Araneae, Pholcidae) using DNA barcoding and morphology https://zookeys.pensoft.net/article/94628/ ZooKeys 1135: 93-118

DOI: 10.3897/zookeys.1135.94628

Authors: Samuel Nolasco, Alejandro Valdez-Mondragón

Abstract: Integrative taxonomy is crucial for discovery, recognition, and species delimitation, especially in underestimated species complex or cryptic species, by incorporating different sources of evidence to construct rigorous species hypotheses. The spider genus Physocyclus Simon, 1893 (Pholcidae, Arteminae) is composed of 37 species, mainly from North America. In this study, traditional morphology was compared with three DNA barcoding markers regarding their utility in species delimitation within the genus: 1) Cytochrome c Oxidase subunit 1 (CO1), 2) Internal Transcribed Spacer 2 (ITS2), and 3) Ribosomal large subunit (28S). The molecular species delimitation analyses were carried out using four methods under the corrected p-distances Neighbor-Joining (NJ) criteria: 1) Automatic Barcode Gap Discovery (ABGD), 2) Assemble Species by Automatic Partitioning (ASAP), 3) General Mixed Yule Coalescent model (GMYC), and 4) Bayesian Poisson Tree Processes (bPTP). The analyses incorporated 75 terminals from 22 putative species of Physocyclus. The average intraspecific genetic distance (p-distance) was found to be < 2%, whereas the average interspecific genetic distance was 20.6%. The ABGD, ASAP, and GMYC methods were the most congruent, delimiting 26 or 27 species, while the bPTP method delimited 33 species. The use of traditional morphology for species delimitation was congruent with most molecular methods, with the male palp, male chelicerae, and female genitalia shown to be robust characters that support species-level identification. The barcoding with CO1 and 28S had better resolution for species delimitation in comparison with ITS2. The concatenated matrix and traditional morphology were found to be more robust and informative for species delimitation within Physocyclus.

Abstract: The spider genus Episinus Walckenaer, 1809 currently contains 66 species worldwide, mostly in warm temperate to tropical areas. This paper describes two new Chinese Episinus species: E. ornithorrhynchus sp. nov. (♂♀) and E. papilionaceous sp. nov. (♀). We add these two new and one known Episinus species to the phylogenetic data matrix of Liu et al. 2016 and reanalyze the data. The new phylogeny recovers the monophyly of Episinus and supports its division into two groups, a finding also supported by morphology.

Revision of the new Australasian orb-weaving spider genus Salsa (Araneae, Araneidae) https://zookeys.pensoft.net/article/82388/ ZooKeys 1102: 107-148

DOI: 10.3897/zookeys.1102.82388

Authors: Volker W. Framenau, Pedro de S. Castanheira

Abstract: A new Australasian genus in the orb-weaving spider family Araneidae Clerck, 1757 is described to include seven species: Salsa fuliginata (L. Koch, 1871) comb. nov. (type species; = Epeira rubicundula Keyserling, 1887) syn. nov.) (Australia, introduced to New Zealand); S. brisbanae (L. Koch, 1867) comb. nov. (Australia); S. canalae (Berland, 1924) comb. nov. (New Caledonia); S. neneba sp. nov. (Papua New Guinea); S. recherchensis (Main, 1954) comb. nov. (Australia); S. rueda sp. nov. (Australia); and S. tartara sp. nov. (Australia; Lord Howe Island endemic). Salsa gen. nov. belongs to the Australasian informal backobourkiine clade and differs from other genera of this clade by a distinct abdominal shape (single posterior abdominal tubercle) and ventral colouration (pale lateral spindle-shaped bands), male pedipalp morphology (C-shaped median apophysis that has teeth-like tubercles inside the basal arch) and the shape of the female epigyne scape (partially translucent and generally shorter than the epigyne plate). Based mainly on male pedipalp morphology within the backobourkiines, Salsa gen. nov. has closest morphological affinities with Acroaspis Karsch, 1878 and Socca Framenau, Castanheira & Vink, 2022.

Phylogenomics of paleoendemic lampshade spiders (Araneae, Hypochilidae, Hypochilus), with the description of a new species from montane California https://zookeys.pensoft.net/article/77190/ ZooKeys 1086: 163-204

DOI: 10.3897/zookeys.1086.77190

Authors: Erik Ciaccio, Andrew Debray, Marshal Hedin

Abstract: Hypochilus is a relictual lineage of Nearctic spiders distributed disjunctly across the United States in three montane regions (California, southern Rocky Mountains, southern Appalachia). Phylogenetic resolution of species relationships in Hypochilus has been challenging, and conserved morphology coupled with extreme genetic divergence has led to uncertain species limits in some complexes. Here, Hypochilus interspecies relationships have been reconstructed and cryptic speciation more critically evaluated using a combination of ultraconserved elements, mitochondrial CO1 by-catch, and morphology. Phylogenomic data strongly support the monophyly of regional clades and support a ((California, Appalachia), southern Rocky Mountains) topology. In Appalachia, five species are resolved as four lineages (H. thorelli Marx, 1888 and H. coylei Platnick, 1987 are clearly sister taxa), but the interrelationships of these four lineages remain unresolved. The Appalachian species H. pococki Platnick, 1987 is recovered as monophyletic but is highly genetically structured at the nuclear level. While algorithmic analyses of nuclear data indicate many species (e.g., all H. pococki populations as species), male morphology instead reveals striking stasis. Within the California clade, nuclear and mitochondrial lineages of H. petrunkevitchi Gertsch, 1958 correspond directly to drainage basins of the southern Sierra Nevada, with H. bernardino Catley, 1994 nested within H. petrunkevitchi and sister to the southernmost basin populations. Combining nuclear, mitochondrial, geographical, and morphological evidence a new species from the Tule River and Cedar Creek drainages is described, Hypochilus xomote sp. nov. We also emphasize the conservation issues that face several microendemic, habitat-specialized species in this remarkable genus.

Island hoppers: Integrative taxonomic revision of Hogna wolf spiders (Araneae, Lycosidae) endemic to the Madeira islands with description of a new species https://zookeys.pensoft.net/article/68015/ ZooKeys 1086: 84-135

DOI: 10.3897/zookeys.1086.68015

Authors: Luís C. Crespo, Isamberto Silva, Alba Enguídanos, Pedro Cardoso, Miquel Arnedo

Abstract: Because of their ability for aerial dispersal using silk and preference for open habitats, many wolf spiders are formidable colonisers. Pioneering arachnologists were already aware of the large and colourful wolf spiders in the Madeira archipelago, currently included in the genus Hogna Simon, 1885. The origins were investigated and species boundaries of Madeiran Hogna examined by integrating target-gene and morphological information. A multi-locus phylogenetic analysis of a thorough sampling across wolf-spider diversity suggested a single origin of Madeiran endemics, albeit with low support. Divergence time estimation traced back their origin to the late Miocene, a time of major global cooling that drove the expansion of grasslands and the associated fauna. Morphological examination of types and newly collected material revealed a new species, hereby described as H. isambertoi Crespo, sp. nov. Additionally, H. blackwalli is revalidated and three new synonymies are proposed, namely H. biscoitoi Wunderlich, 1992, junior synonym of H. insularum Kulczynski, 1899, H. schmitzi Wunderlich, 1992, junior synonym of H. maderiana (Walckenaer, 1837), and Arctosa maderana Roewer, 1960 junior synonym of H. ferox (Lucas, 1838). Species delimitation analyses of mitochondrial and nuclear markers provided additional support for morphological delineations. The species pair H. insularum and H. maderiana, however, constituted an exception: the lack of exclusive haplotypes in the examined markers, along with the discovery of intermediate forms, pointed to hybridisation between these two species as reported in other congeneric species on islands. Finally, the conservation status of the species is discussed and candidates for immediate conservation efforts are identified.

A new genus of bamboo culm tarantula from Thailand (Araneae, Mygalomorphae, Theraphosidae) https://zookeys.pensoft.net/article/76876/ ZooKeys 1080: 1-19

DOI: 10.3897/zookeys.1080.76876

Authors: Chaowalit Songsangchote, Zongtum Sippawat, Wuttikrai Khaikaew, Narin Chomphuphuang

Abstract: Bamboo plays an important role in the animal world, including providing a nutritious food source, shelter, and habitat. Inside of bamboo culm, we discovered a new genus of tarantula, which we describe here as Taksinus gen. nov. (♂♀). Specimens of this new tarantula were collected from Mae Tho, Mueang Tak district, Tak province, in Thailand, making it geographically distant from any other arboreal genera. Genital morphology was used to diagnose its genus, which is supported by distributional data, natural history, morphological characters, and photographic illustrations of the male and female. Diagnosis of the new genus was determined by distinguishing its different characters from those of other arboreal theraphosid spiders distributed throughout Southeast Asia. This tarantula’s specialization is that it lives in the stalks of the Asian bamboo Gigantochloa sp.

Incongruent molecular and morphological variation in the crab spider Synema globosum (Araneae, Thomisidae) in Europe https://zookeys.pensoft.net/article/64116/ ZooKeys 1078: 107-134

DOI: 10.3897/zookeys.1078.64116

Authors: Karin Urfer, Tamara Spasojevic, Seraina Klopfstein, Hannes Baur, Liana Lasut, Christian Kropf

Abstract: Establishing species boundaries is one of the challenges taxonomists around the world have been tackling for centuries. The relation between intraspecific and interspecific variability is still under discussion and in many taxa it remains understudied. Here the hypothesis of single versus multiple species of the crab spider Synema globosum (Fabricius) is tested. The wide distribution range as well as its high morphological variability makes this species an interesting candidate for re-evaluation using an integrative approach. This study combines information from barcoding, phylogenetic reconstruction based on mitochondrial CO1 and ITS2 of more than 60 specimens collected over a wide range of European localities, and morphology. The findings show deep clades with up to 6% mean pairwise distance in the CO1 barcode without any biogeographical pattern. The nuclear ITS2 gene did not support the CO1 clades. Morphological assessment of somatic and genital characters in males and females and a morphometric analysis of the male palp uncovered high intraspecific variation that does not match the CO1 or ITS2 phylogenies or biogeography either. Screening for endosymbiotic Wolbachia bacteria was conducted and only a single infected specimen was found. Several scenarios might explain these inconsistent patterns. While the deep divergences in the barcoding marker might suggest cryptic or ongoing speciation or geographical isolation in the past, the lack of congruent variation in the nuclear ITS2 gene or the studied morphological character systems, especially the male palp, indicates that S. globosum might simply be highly polymorphic both in terms of its mtDNA and morphology. Therefore, more data on ecology and behaviour and full genome sequences are necessary to ultimately resolve this taxonomically intriguing case.

Taxonomic study on fourteen symphytognathid species from Asia (Araneae, Symphytognathidae) https://zookeys.pensoft.net/article/67935/ ZooKeys 1072: 1-47

DOI: 10.3897/zookeys.1072.67935

Authors: Ya Li, Shuqiang Li, Yucheng Lin

Abstract: Fourteen symphytognathid species belonging to three genera are examined, including the descriptions of eight new species and two new genera from China, Vietnam, Thailand and Myanmar: Patu Marples, 1951: P. catba S. Li & Lin, sp. nov. (♂, Vietnam), P. dakou S. Li & Lin, sp. nov. (♂♀, China), P. damtao S. Li & Lin, sp. nov. (♂, Vietnam), P. jiangzhou S. Li & Lin, sp. nov. (♀, China), P. jidanweishi Miller, Griswold & Yin, 2009 (♂♀, China), P. nagarat S. Li & Lin, sp. nov. (♂♀, Thailand), P. nigeri Lin & S. Li, 2009 (♀, China), P. putao S. Li & Lin, sp. nov. (♀, Myanmar), P. qiqi Miller, Griswold & Yin, 2009 (♀, China) and P. xiaoxiao Miller, Griswold & Yin, 2009 (♂♀, China); Kirinua S. Li & Lin, gen. nov.: K. maguai S. Li & Lin, sp. nov. (♂♀, China) and K. yangshuo S. Li & Lin, sp. nov. (♂♀, China); Swilda S. Li & Lin, gen. nov.: S. longtou (Miller, Griswold & Yin, 2009), comb. nov. (♂♀, China) is transferred from Crassignatha Wunderlich, 1995 and S. spinathoraxi (Lin & S. Li, 2009), comb. nov. (♂♀, China) is transferred from Patu. Diagnoses, descriptions and illustrations are provided for new taxa, as well as a distribution map. The males of P. xiaoxiao and S. longtou are described for the first time. Type specimens of P. jidanweishi, P. nigeri, P. qiqi, P. xiaoxiao, S. longtou and S. spinathoraxi are re-examined and photographed. All Asian Patu species are revised and two species, P. kishidai Shinkai, 2009 and P. bispina Lin, Pham & S. Li, 2009, are transferred to Crassignatha and proposed as new combinations: Crassignatha kishidai comb. nov. and C. bispina comb. nov. In addition, DNA barcodes and genetic distances of ten species treated in this paper were obtained to confirm identification.

Another Laurasian connection in the Early Eocene of India: Myrmecarchaea spiders (Araneae, Archaeidae) https://zookeys.pensoft.net/article/72515/ ZooKeys 1071: 49-61

DOI: 10.3897/zookeys.1071.72515

Authors: Hannah M. Wood, Hukam Singh, David A. Grimaldi

Abstract: The first fossil Archaeidae in Cambay amber from India, of Eocene age, is documented. The inclusion is a spider exuvium and is placed as Myrmecarchaea based on the presence of elongated legs, a slightly elongated pedicel with lateral spurs, and a diastema between coxae III and IV that is similar to M. antecessor from Oise amber. The previous occurrences of the genus are from Baltic and Oise amber, both of Eocene age. Because most spiders, including Archaeidae, only molt as juveniles, the exuvium does not have adult features nor have distinct species-specific features, and a new taxon is not erected. This new record further extends the distribution of the family and genus to India 50–52 million years ago. Myrmecarchaea in Indian Cambay amber provides additional evidence that India in the Early Eocene had affinities with the Palearctic mainland rather than showing Gondwanan insularity.

Four new species of the jumping spider genus Portia (Araneae, Salticidae) from China https://zookeys.pensoft.net/article/72805/ ZooKeys 1068: 27-40

DOI: 10.3897/zookeys.1068.72805

Authors: Xin Xu, Xianjin Peng, Daiqin Li

Abstract: We diagnose and describe four new species of Portia Karsch, 1878 and describe for the first time the male of P. zhaoi Peng, Li & Chen, 2003 from China based on morphological characters. The females of Portia bawang sp. nov. have the narrowest epigyne orifice. The males of Portia erlangping sp. nov. have the shortest embolus among all the species. The females of Portia fajing sp. nov. can be distinguished from other species by the anterior orifice margin, which is nearly parallel to the posterior orifice margin. The males of Portia xishan sp. nov. can be identified by the tegular furrow which extends to form a membrane and by the tegular apophysis which is obscured; the females of Portia xishan sp. nov. can be diagnosed by the slit-like epigynal orifice. The males of P. zhaoi have the longest embolus among all the species, and females can be diagnosed by the circular epigyne orifice and the longest copulatory ducts. To facilitate future identification, we also provide the GenBank accession codes of the DNA barcode gene, Cytochrome c oxidase subunit I (COI), for all the type specimens.

The first Western Palearctic record of Euprosthenops Pocock (Araneae, Pisauridae), with description of a new species from Israel https://zookeys.pensoft.net/article/74119/ ZooKeys 1065: 13-27

DOI: 10.3897/zookeys.1065.74119

Authors: Sergei Zonstein, Yuri M. Marusik

Abstract: The primarily Afrotropical genus Euprosthenops Pocock, 1897 is recorded in the Western Palearctic for the first time. A diagnosis and an illustrated description of E. insperatus sp. nov., based on a single male from southern Israel, are provided. Considering the structure of the male palp, the holotype of E. insperatus sp. nov. resembles males of two widespread African species, E. australis Simon, 1898 and E. proximus Lessert, 1916; it differs from them by colouration pattern as well as by the different shapes of the retrolateral tibial apophysis and the palpal sclerites. A short survey of the regional insect and spider genera of the paleotropical origin is also presented.
