Type material examined. Holotype ♂: CHINA, Yunnan Province: Xishuangbanna Dai Autonomous Prefecture, Menghai County, Mengsong Town , Mengsong Township Central Promary School ; 22.0731°N, 100.5600°E; elev. 1300 m; 1 August 2020; Z.C. Li et al. leg. (LJ 202004222 in CBEE) . Paratypes: 1♂ 1♀, same data as holotype (LJ202004228, 202004243, in CBEE) . 2♀, Xishuangbanna Dai Autonomous Prefecture , Mengla County, Menglun Town ; Baka Xiaozhai; 22.0700°N, 101.2000°E; elev. 800 m; 24 July 2020; Z.C. Li et al. leg. (LJ202003774, 202003853, in CBEE)

Diagnosis. For male see diagnosis under Asiopisinus cheni sp. nov.. Male of A. ornithorhynchus ( Liu,Agnarsson, Liu & Zhu, 2022) comb. nov. also resembles those of A. pseudonubilus (Liang, Liu, Yin & Yu, 2025) comb. nov. (cf. Fig. 12 and Liang et al. 2025: figs 5D–F, 6) in having nearly triangular embolic base (EB) and embolus (E) arising from embolic base at 3 o’clock position, but can be recognized by: 1) sperm duct (SD) in tegulum (T) unparallel to margins of embolic base (vs. parallel); 2) median apophysis (MA) extending to 4/5 of width of bulb in ventral view (vs. 1/2); and 3) sperm duct in embolic base strongly curved to C-shaped in ventral view (vs. slightly curved to S-shaped). For female see Liu et al. (2022).

Description. See Liu et al. (2022).

Remarks. This species is transferred to Asiopisinus gen. nov. due to similarity of the male palp and epigyne to those in the generotype.

Distribution. China (Yunnan) ( Fig. 22 ).
