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’ HOWARDI PETRUNKEVITCH, 1925 INCERTAE SEDIS Oedothorax howardi Petrunkevitch, 1925: 174 , pl. 8, figs 6–9 (Df). Unexamined material: USA : Tennessee , Clarksville , 3♀ 1921, coll. S. E. Crumb , sent by L. O. Howard ( Petrunkevitch, 1925 ). No type was designated . Diagnosis: Females: This species differs from Oedothorax s.s. and its related genera by the epigynal morphology seemingly without a fused middle part of the dorsal and ventral plates (fig. 6 in Petrunkevitch, 1925 ), as well as by the tibial chaetotaxy (1-1-1-1) (2-2-1- 1 in Oedothorax , Callitrichia and Mitrager ) and the absence of trichobothria on metatarsus I (present in Oedothorax , Callitrichia and Mitrager ). Males: Unknown. Distribution: USA : Tennessee . Remarks: The information provided in Petrunkevitch (1925) suggests that this species does not belong to Oedothorax s.s. , nor is it sufficient for assigning this species to any other existing taxa. Due to the unavailability of specimens, and limited information from the original description, the relationship of this species to other erigonines remains unclear.
