Project description:Two Liphistius species of the primitively segmented spider family Liphistiidae, collected from Loikaw (Kayah State) and Pinlaung (Shan State), Myanmar, are diagnosed and described as new to science based on their genital morphology: Liphistius hpruso sp. nov. (♀), Liphistius pinlaung sp. nov. (♂♀).
Project description:We diagnose and describe three new species of the primitively segmented spider genus Liphistius from Thailand, based on male palp and female genital morphology: L.hatyai Zhan & Xu, sp. nov. (♂♀), L.keeratikiati Zhan & Xu, sp. nov. (♂♀), and L.inthanon Zhan & Xu, sp. nov. (♂♀). The classification of the three new species of Liphistius is discussed: L.hatyai sp. nov. and L.keeratikiati sp. nov. are assigned to the trang-group, and L.inthanon sp. nov. is placed in the bristowei-group according to male palp and female genital morphology.
Project description:Four new species of Liphistius belonging to the birmanicus species group are described from Myanmar based on both sexes: L.kalaw Zhan & Xu, sp. nov. (♂♀), L.kanpetlet Zhan & Xu, sp. nov. (♂♀), L.nawngau Zhan & Xu, sp. nov. (♂♀) and L.rostratus Zhan & Xu, sp. nov. (♂♀). Currently, Myanmar stands as the westernmost country where Liphistius is distributed, with the new species L.kanpetlet sp. nov. being found in the westernmost region of Myanmar.
Project description:Two new species of tetragnathid spiders from Guizhou and Sichuang provinces of China are described: Diphyaguiyang J. Zhang & H. Yu, sp. nov. (♂♀) and Diphyaweimiani J. Zhang & H. Yu, sp. nov. (♀). Detailed descriptions, diagnoses, and photographs are provided for these two species, as well as a key and a distribution map for Chinese Diphya species. DNA barcodes (a partial fragment of the mitochondrial cytochrome oxidase subunit I gene, COI) of both new species were obtained for species delimitation, matching of different sexes, and future use in molecular studies.
Project description:Five Liphistius Schiödte, 1849 species of the primitively segmented spider family Liphistiidae are currently known from Myanmar. Here, we described a new species, Liphistius pyinoolwin sp. nov. (♂♀), which was collected from Pyin Oo Lwin, Mandalay Region, Myanmar, diagnosed based on its genital morphology. The specimens (2♂♂, 5♀♀) collected by Walter C. Sedgwick from Pyin Oo Lwin in 1982 were misidentified as L. birmanicus Thorell, 1897 and are treated here as the newly described species. Accordingly, we described the males of L. birmanicus for the first time, redescribed its female, using newly collected specimens from Yadò, Than Taung and Kalekho Atet townships, Kayin State. We also provided information on the variation in genital morphology of both species, and their relationships within the birmanicus-group of species.
Project description:Seven new species of the primitive segmented spider genus Liphistius are described and assigned to species groups based on characters of the male palp and vulva plate. The bristowei group includes L.dawei Sivayyapram & Warrit, sp. nov. (♂♀) from southeastern Myanmar, L.choosaki Sivayyapram & Warrit, sp. nov. (♀) from northwestern Thailand, and L.lansak Sivayyapram & Warrit, sp. nov. (♀) from western Thailand; the trang group (Complex A) contains L.kaengkhoi Sivayyapram & Warrit, sp. nov. (♂♀), L.hintung Sivayyapram & Warrit, sp. nov. (♂♀), L.buyphradi Sivayyapram & Warrit, sp. nov. (♂♀), and L.champakpheaw Sivayyapram & Warrit, sp. nov. (♂♀) from central Thailand.
Project description:The present paper describes two new Clubionacorticalis-group species collected from Xishuangbanna, Yunnan Province of China: Clubionasubmoralis sp. n. (♀♂) and Clubionapollicaris sp. n. (♀♂).
Project description:Nine new species of the orb-weaver spider family Araneidae Clerck, 1757 from Menglun Town, Xishuangbanna, Yunnan, China are described: Acusilastongisp. nov. (♂♀), Chorizopesyuisp. nov. (♂♀), Chorizopesoidesguoisp. nov. (♂♀), Deionechenisp. nov. (♀), D.yangisp. nov. (♂♀), Hypsosingapullasp. nov. (♂♀), Mangorabaiisp. nov. (♂♀), M.cephalasp. nov. (♂♀) and Miloniagemellasp. nov. (♂♀). The genus Milonia Thorell, 1890 is recorded from China for the first time. The previous description of Chorizopesoideswulingensis (Yin, Wang & Xie, 1994) from Libo County, Guizhou by Mi and Wang (2018) refers to Chorizopesoidesannasestakovaesp. nov. (♂♀). Diagnostic photos of the habitus and copulatory organs of the new species are provided.
