A new species of Liphistius from Myanmar and description of the actual male of L. birmanicus Thorell, 1897 (Araneae, Mesothelae, Liphistiidae) https://zookeys.pensoft.net/article/59102/ ZooKeys 1031: 41-58

DOI: 10.3897/zookeys.1031.59102

Authors: Xin Xu, Li Yu, Khin Pyae Pyae Aung, Long Yu, Fengxiang Liu, Wai Wai Lwin, Men Zing Sang, Daiqin Li

Abstract: 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.

A taxonomic monograph of the liphistiid spider genus Heptathela, endemic to Japanese islands https://zookeys.pensoft.net/article/34494/ ZooKeys 888: 1-50

DOI: 10.3897/zookeys.888.34494

Authors: Xin Xu, Hirotsugu Ono, Matjaž Kuntner, Fengxiang Liu, Daiqin Li

Abstract: Among the eight extant genera of primitively segmented spiders, family Liphistiidae, two are confined to East Asian islands, Heptathela Kishida, 1923 and Ryuthela Haupt, 1983. In this paper, a taxonomic revision of the genus Heptathela (Heptathelinae) from Kyushu and Ryukyu archipelago, Japan is provided. This study follows a multi-tier species delimitation strategy within an integrative taxonomic framework that is presented in a parallel paper, in which diagnosable lineages are considered as valid species. There, the initial hypothesis of species diversity (19) based on classical morphological diagnoses is tested with multiple species delimitation methods aimed at resolving conflict in data. This revision follows those analyses that converge on the species diversity of 20, which includes a pair of cryptic species that would have been undetected with morphology alone. After this revision, eight previously described species remain valid, two junior synonyms are proposed, and 12 new Heptathela species are described based on diagnostic evidence. To ease identification and to hint at putative evolutionary units, Heptathela is divided into three groups. The Kyushu group contains H. higoensis Haupt, 1983, H. kikuyai Ono, 1998, H. kimurai (Kishida, 1920), and H. yakushimaensis Ono, 1998; the Amami group contains H. amamiensis Haupt, 1983, H. kanenoi Ono, 1996, H. kojima sp. nov., H. sumiyo sp. nov., and H. uken sp. nov.; and the Okinawa group contains H. yanbaruensis Haupt, 1983, H. aha sp. nov., H. gayozan sp. nov., H. kubayama sp. nov., H. mae sp. nov., H. otoha sp. nov., H. shuri sp. nov., H. tokashiki sp. nov., H. unten sp. nov., and H. crypta sp. nov. Heptathela helios Tanikawa & Miyashita, 2014 is not assigned to a species group. A combination of diagnostic tools augments the morphological diagnoses that, in isolation, would be prone to error in morphologically challenging groups of organisms.
