Diagnosis. For male see the diagnosis under Asiopisinus baoshanensis ( Liu, Irfan & Peng, 2019) comb. nov.. For female see Liang et al. (2025).

Description. Male: Measurements: Total length 4.22. Carapace 1.73 long, 1.57 wide. Opisthosoma 2.37 long, 1.43 wide. Eyes: AME 0.14, ALE 0.13, PME 0.13, PLE 0.13, AME‒AME 0.07, AME‒ALE 0.02, PME‒PME 0.06, PME‒PLE 0.05, AME‒PME 0.07, ALE‒PLE 0.02. Legs missing.

Palp ( Fig. 8 ): Median apophysis (MA) huge, extending to retrolateral part of bulb in ventral view, with wavy groove ( Fig. 8D ) at median part of median apophysis that conducting embolus (E). Prolateral arm of conductor (PC) nearly triangular, lateral margins of prolateral arm of conductor with right angle (arrow in Fig. 8A ) in prolateral view, posterior corner of prolateral arm of conductor with 4 denticles. Embolic base (EB) rounded. Embolus arising from embolic base at 7 o’clock position.

Colouration ( Figs 14C , 15C , 16C ): Carapace brown, with 4 light brown markings located lateral and posterolateral part. Cephalic region red. Fovea black. Endites with gray distal parts. Sternum dark brown. Opisthosoma black, dorsum with 6 inverted V-shaped black stripes, venter with posterior white transversal stripe.

Female: See Liang et al. (2025).

Remarks. The species is transferred to Asiopisinus gen. nov. based on its similarity to the type species: e.g. epigynal atrium (A) with septum (Se), and windings of copulatory ducts (CD) shorter than spermathecae (S).

This species might potentially be conspecific with Asiopisinus baoshanensis ( Liu, Irfan & Peng, 2019) comb. nov. or A. yoshidai ( Okuma, 1994) comb. nov.. More discussions see remarks under A. baoshanensis .

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