Episinus Walckenaer 1809

Genus Episinus Walckenaer, 1809 Type species. Episinus truncatus Latreille, 1809 from Europe. Remarks. Liang et al. (2025) considered Episinus longabdomenus Zhu, 1998, E. nanyue Yin, 2012, E. papilionaceous Liu, Agnarsson, Liu & Zhu, 2022, and E. xiushanicus Zhu, 1998 belonging to the angulatus group. The copulatory organs of these four species share the same characteristics with E. truncatus, including cymbium longer than wide, cymbial hook (CH) located in anterior part of cymbium and elongated prolaterally, extra tegular apophysis (ETA) present, median apophysis (MA) and tegular apophysis (TA) long and strip-shaped (Fig. 17, 20, Knoflach & Pfaller 2004: fig. 20b, Agnarsson et al. 2007: figs 24‒27, 180); windings of copulatory ducts (CD) much longer than spermathecae (S) (Figs 18, 19, Knoflach & Thaler 2000: fig. 22). Therefore, we provide the photos of these four species to compare with those of Asiopisinus gen. nov..
