Etymology.

The specific name comes from the Chinese word “ zang ”, the name of one of the Chinese ethnic minorities that mainly live in Xizang and Sichuan provinces of China; noun in apposition.

Diagnosis.

This new species can be separated from other Acantholycosa species by the lanceolate end and retrolateral serrate margin of the terminal apophysis ventrally (Fig. 8 D View Figure 8 , arrow). The new species is most similar to A. zhangi sp. nov. in having a similar conformation of the copulatory organs (Figs 7 A – E View Figure 7 , 8 B – F View Figure 8 , 9 B, C View Figure 9 cf. Figs 10 A – E View Figure 10 , 11 B – F View Figure 11 , 12 B, C View Figure 12 ), but it can be differentiated by the triangular paleal apophysis with a pointed tip in ventral view (Figs 7 A, C View Figure 7 , 8 B, D, F View Figure 8 ) (vs. rectangular with a wavy tip; Figs 10 A, C View Figure 10 , 11 B, D, F View Figure 11 ); the median apophysis axe shaped without spine (Figs 7 A View Figure 7 , 8 B, D View Figure 8 ) (vs. rectangular with hook-shaped basal arm and triangular spine; Figs 10 A View Figure 10 , 11 B, D View Figure 11 ); embolus with subparallel margins abruptly tapering at tip (Figs 7 A, C View Figure 7 , 8 B, D, F View Figure 8 ) (vs. tapering from base to tip, slightly curved towards tip; Figs 10 A, C View Figure 10 , 11 B, D, F View Figure 11 ). Females can be distinguished by having an epigyne with a pair of distinct hoods (Figs 7 D View Figure 7 , 9 B View Figure 9 ) (vs. a pair of less pronounced hoods; Figs 10 D View Figure 10 , 12 B View Figure 12 ); width of hoods equal to septal posterior width (Figs 7 D View Figure 7 , 9 B View Figure 9 ) (vs. one-third septal posterior width; Figs 10 D View Figure 10 , 12 B View Figure 12 ); septal base hexagonal (Figs 7 D View Figure 7 , 9 B View Figure 9 ) (vs. trapezoidal; Figs 10 D View Figure 10 , 12 B View Figure 12 ); spermathecal heads with wart-like projections (Figs 7 E View Figure 7 , 9 C View Figure 9 ) (vs. smooth; Figs 10 E View Figure 10 , 12 C View Figure 12 ).

Epigyne (Figs 7 D, E View Figure 7 , 9 B, C View Figure 9 ). Hoods distinct, clearly separated from each other. Atrium as long as wide. Septum with distinct stem and hexagonal base equal in length and width. Width of hoods equal to septal posterior width. Copulatory openings located at anterolateral margin of septal base. Spermathecae heads oval with small wart-like projections. Spermathecal stalks slightly curved. Fertilization ducts slender, width between two ducts longer than length of duct.

Distribution.

China (Xizang, Sichuan), Nepal.

Comment.

This species belongs to the A. solituda - group.

Remark.

Although the specimens of A. baltoroi from Nepal were not examined, it is clear from the descriptions in Buchar (1976), Marusik et al (2004), Marusik and Omelko (2017) that A. baltoroi from Nepal is identical to A. zang sp. nov.
