Etymology.
The specific name is derived from the type locality the location of the type locality in Tibet; Xizang is a Chinese name for Tibet.
Diagnosis.
This species can be distinguished from all other congeners in having the posterior arm of conductor short and with a hook-shaped end, the anterior arm of the conductor terminating at about the 9 o’clock position, the embolus originated at about 7:30 o’clock (Figs 14A, B View Figure 14 , 15C-E View Figure 15 ), the copulatory ducts long, with 3 turns, and with an indistinct membranous part (Figs 14C, D View Figure 14 , 15F, G View Figure 15 ).
