Project description:A new genus of the subfamily Coelotinae F. O. Pickard-Cambridge, 1893, Yunguiriusgen. nov. is described, comprising two new species and three species previously described in Draconarius Ovtchinnikov, 1999, all from southwest China: Y.duogesp. nov. (♀), Y.xiangdingsp. nov. (♀), Y.ornatus (Wang, Yin, Peng & Xie, 1990) comb. nov. (♂♀) (the type species of Yunguiriusgen. nov.), Y.subterebratus (Zhang, Zhu & Wang, 2017) comb. nov. (♀), and Y.terebratus (Peng & Wang, 1997) comb. nov. (♂♀). Molecular analyses support Yunguiriusgen. nov. as a monophyletic group, with the Sinodraconarius clade as its sister group: Yunguiriusgen. nov. + (Hengconarius + (Nuconarius + Sinodraconarius)).
Project description:BackgroundThe genus Heser (Araneae, Gnaphosidae) belongs to the Zelotes group, and is currently known to comprise 10 species distributed in Africa, Asia, Europe and North America. The type species is Heser malefactor Tuneva, 2004 from Kazakhstan.New informationA new spider species, Heser stoevi sp. nov. (male and female) found in Koytendag Mountains, southeastern Turkmenistan is described and illustrated. It is morphologically close to H. aradensis (Levy, 1998) from Israel but can be readily distinguished by the longer embolus, the smaller and flattened conductor, the lack of retrolateral tibial apophysis, all this coupled with very distinctive female copulatory organs. The new species was found under stones in arid grassland habitats.
Project description:A new linyphiid genus Callosagen. n., with two new species Callosa ciliatasp. n. (♂♀, type species) and Callosa baiseensissp. n. (♂♀), from southwest China are described. Detailed description of genitalic characters and somatic features is provided, as well as light microscopy and SEM micrographs of each species. Callosagen. n. was found in caves in Yunnan and Guangxi, and its copulatory organs are similar to those of Bathyphantes and Porrhomma, but differ greatly in details. The monophyly and placement of Callosagen. n. are supported by the results of molecular analysis.
Project description:A new mysmenid genus, Chimena gen. nov., is reported from China. Two new species: C.qiong sp. nov. (Hainan, ♂♀, the type species) and C.nantou sp. nov. (Taiwan, ♀) are illustrated and described in detail. A new combination is suggested: Chimenataiwanica (Ono, 2007) comb. nov. (Taiwan, ♂♀, transferred from Mysmena Simon, 1894). The molecular phylogeny and morphological characters were used to discuss the taxonomy and circumscription of the newly erected genus.
Project description:A list of 26 gnaphosid species belonging to 14 genera collected in Jiangxi Province, China, is provided. Three new species of ground spiders from Jiangxi Province of China are diagnosed, described, and illustrated: Haplodrassusyinae Liu, sp. nov. (♂♀), Hitobiaxiaoxi Liu, sp. nov. (♂), and Zelotesdingnan Liu, sp. nov. (♂♀). Haplodrassusyinae Liu, sp. nov. was previously erroneously recorded in Jiangxi Province as H.montanusYin et al., 2012.
Project description:The spider genus Arboricaria Bosmans, 2000 is redefined and an updated diagnosis given. The differences between Arboricaria and Micaria Westring, 1851 are discussed in detail. A key to all five species of the genus is provided. One new species, Arboricaria zonsteini sp. n. (♂♀), is described based on specimens from Kyrgyzstan and Azerbaijan. One new synonym is proposed: Arboricaria koeni Bosmans in Bosmans & Blick, 2000, syn. n. is assigned to Arboricaria sociabilis Kulczyński in Chyzer & Kulczyński, 1897. Data on the distribution of Arboricaria in Russia and adjacent countries are presented with references to the papers on local spider faunas.
Project description:The spider genus Pterotricha Kulczyński, 1903 (Gnaphosidae) is surveyed in Iran. To date, three species of this genus were known in the country: P.loeffleri (Roewer, 1955), P.lentiginosa (C. L. Koch, 1837) and P.pseudoparasyriaca Nuruyeva & Huseynov, 2016. Here two new species are described, P.kovblyuki Zamani & Marusik, sp. n. (♂, western Iran) and P.montana Zamani & Marusik, sp. n. (♀, central and southwestern Iran), and P.cf.dalmasi Fage, 1929 (from Algeria to Jordan) is reported in Iran for the first time. Pterotrichatikaderi Gajbe, 1983 syn. n. (India) and P.loeffleri (Roewer, 1955), syn. n. are synonymized with P.strandi Spassky, 1936 (hitherto known from Turkmenistan only). The record of P.lentiginosa from Iran is apparently based on misidentification. A distribution map of the genus in Iran with new provincial records is provided. In addition, Iranotricha Zamani & Marusik, gen. n., a new genus closely related to Pterotricha, is described from southeastern Iran with the type species I.lutensis Zamani & Marusik, sp. n.
Project description:A new genus of the subfamily Coelotinae F.O. Pickard-Cambridge, 1893, Sinodraconariusgen. n., with four new species, S. cawarongensissp. n. (♂♀), S. muruoensissp. n. (♂♀), S. sangjiuensissp. n. (♂♀, type species), S. yuisp. n. (♂♀) and S. patellabifidus (Wang, 2003) comb. n., ex. Draconarius Ovtchinnikov, 1999 is described. The genus is restricted to Southwest China. Sinodraconariusgen. n. is most similar to Draconarius but can be distinguished by the shape of the copulatory organs. The DNA barcodes of all species were documented for future use.
Project description:Baiyueriusgen. nov., a new genus of the subfamily Coelotinae F. O. Pickard-Cambridge, 1893 is described, including five new species: B.daxisp. nov. (♀), B.pindongsp. nov. (♂), B.tamdaosp. nov. (♀), B.zhupingsp. nov. (♂) and B.zuojiangsp. nov. (♂♀), from southern China and northern Vietnam. Our molecular phylogenetic analyses support Baiyuerius gen. nov. as monophyletic and as a sister group of the newly established genus Yunguirius Li, Zhao & Li, 2023.
