Evolution of nuptial-gift-related male prosomal structures: taxonomic revision and cladistic analysis of the genus Oedothorax (Araneae: Linyphiidae: Erigoninae) Author Lin, Shou-Wang Author Lopardo, Lara Author Uhl, Gabriele text Zoological Journal of the Linnean Society 2022 2021-11-20 195 417 584 journal article 115951 10.1093/zoolinnean/zlab033 75b10efe-a17d-4d10-b46e-094c6a7ebf01 0024-4082 6967774 BE2B3859-8F6A-4543-8A69-91840F82377B ‘OEDOTHORAX’ BIANTU ZHAO & LI, 2014 INCERTAE SEDIS Oedothorax biantu Zhao & Li, 2014: 36 , figs 67A–F, 68A, B (Df). Type material: Holotype : China , Yunnan : Menglun Town : Xishuangbanna Tropical Botanical Garden ( 21°54’38’’ N , 101°16’518’’ E ), c. 627 m , bamboo plantation, fogging, ♀ 22.xi.2009 (not examined). Diagnosis: Females: This species differs from all Oedothorax , Mitrager , Callitrichia and their related genera by the tibial chaetotaxy (1-1-1-1), the knob on each side of ventral plate of the epigyne and the long slits on the ventral plate (figs 67A and 68A in Zhao & Li, 2014 ). Males: Unknown. Distribution: Known only from type locality. Habitat: See collecting data of holotype . Remarks: This species has tibial chaetotaxy 1-1- 1-1, unlike the uniform pattern 2-2-1-1 among all other examined species in this study. The epigynal structure of this species is also prominently different from the simple composition in other Oedothorax species by having a knob on each side of the ventral plate and the long slits on the ventral plate of the epigyne. Therefore, this species does not belong to Oedothorax , and its relationship to other erigonines remains unknown.
