Hu, Changhao, Wei, Mian, Liu, Jie & Xu, Xiang, 2025, Asiopisinus gen. nov., a new genus of the family Theridiidae Sundevall, 1833 (Araneae, Theridiidae) from eastern Asia, Zootaxa 5660 (4), pp. 475-504 : 476

Subfamily Spintharinae Simon, 1894

Diagnosis. Conductor huge and folded, cheliceral base thin, tarsal comb bristle dorsal margin notched, abdomen with humps, colulus small, and web modified ( Agnarsson 2004).

Composition. The subfamily Spintharinae currently contains 11 extant genera: Brunepisinus Yoshida & Koh, 2011 , Chrosiothes Simon, 1894 , Episinus Walckenaer, 1809 , Janula Strand, 1932 , Moneta O. Pickard-Cambridge, 1870 , Neopisinus Marques, Buckup & Rodrigues, 2011 , Pycnoepisinus Wunderlich, 2008 , Spintharus Hentz, 1850 , Stemmops O. Pickard-Cambridge, 1894 , Thwaitesia O. Pickard-Cambridge, 1881 , and Vigdisia Agnarsson, Kuntner, Yu & Gregorič, 2024 ( Agnarsson 2004; Durán-Barrón et al. 2013; Liu et al. 2016; Rodrigues et al. 2022; Gregorič et al. 2024), the new genus Asiopisinus gen. nov. here described representing the 12th genus.

Remarks. Wunderlich (2008) used the subfamily name Episinae. In the current paper, we use Spintharinae following Agnarsson (2004) and Liu et al. (2016). The revision of the subfamily name needs to be carried out in the future.

The largest genus of this subfamily, Episinus , exhibits diverse genital structures, e.g. E. antipodianus O. Pickard-Cambridge, 1880 from New Zealand and E. gibbus Zhu & Wang, 1995 from China ( Court 1982; Zhu 1998). Therefore, in the following diagnosis of Asiopisinus gen. nov., we just compare Asiopisinus gen. nov. with Episinus species that have similar genital structures to E. truncatus Latreille, 1809 (type species of Episinus ). Further generic revision of Episinus may be needed.
