Comments. 54 species are transferred into the genus from Ptocasius and Menemerus because they are morphologically consistent with the type species and the related congeners. However, some species are uncertain, such as Y. pilosa , and Y. stemmleri , which present a different male palp from that of Yaginumaella , indicating they could not be actual members. They are also being transferred because they should have a similar habitus with Yaginumaella rather than Ptocasius (although their habitus has not been shown, a typical pattern of the described species in Żabka, 1981 was provided ( Żabka 1981 : fig. 3), which is consistent with Yaginumaella ) and thus their generic position also needs further confirmation. The generic position of some remainders in Ptocasius , also requires additional attention. For example, P. linzhiensis ( Hu, 2001 ) (transferred from Morgus ) shares similar copulatory organs with the type species, but the habitus information is lacking, making the generic position cannot be confirmed appropriately; P. dian Wang, Mi & Peng, 2023 and P. vittatus Song, 1991 present a similar habitus pattern to the type species, but different in epigynal structure. Moreover, species described by Żabka (1981) and Yang and Peng (2023) are mostly known only from single females, and some of them share very similar epigynal structures, indicating the presence of potential synonyms and the need for further taxonomic revisions. Ptocasius zabkai Yang & Peng, 2023 and Y. zonata were collected in the sites close to each other and share indistinguishable epigynal structures and thus are considered conspecific. We act as First Revisor per ICZN (1999 ) and assign the former as a synonym of the latter. Thyene incognita ( Żabka, 1981 ) , comb. nov. is proposed because the path of the copulatory duct is almost identical to some of the Asian Thyene species. Pancorius lobatus (Peng, Tso & Li, 2002) , comb. nov. (transferred from Yaginumaella ) is proposed because it is closely similar to P. submontanus Prószyński, 1992 , and it could be a junior synonym of the latter.
