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’ TRILINEATUS SAITO, 1934 INCERTAE SEDIS Oedothorax trilineatus Saito, 1934: 311 , pl. 13, fig. 18, pl. 15, fig. 61 (Df). Oedothorax trilineatus , Saito, 1959: 79 , fig. 84a–c (f). Material: Japan : Nemuro , 4♀ , leg. S. Motoda , 15.vii.1931 , not examined. No type material was designated . Diagnosis: Females: This species can be distinguished by the black prosoma, the black opisthosoma with three oblique white markings at the sides, and the white/ black annulated legs and palps. Males: unknown Distribution: Japan : Nemuro. Remarks: According to Saito (1934) , this species has prosoma and opisthosoma uniformly black in colour, and legs are white annulated with black, different from the yellow to dark-brown coloration of Oedothorax and Mitrager species. Furthermore, according to his description, three out of four specimens have leg II as the shortest leg, in comparison to leg III as the shortest leg in Linyphiidae in general. Therefore, this species is most likely not a linyphiid.
