T 8 wide, extended laterally and tapered ventrally on each side. Epiproct with pair of setae. Hypoproct with narrow anteromedial process. Cercus with long and sinuate setae. Spermathecae (2 + 1) cylindrical, constricted medially, with narrow apical invagination.

Diagnosis.

Male S 5 with a small densely setulose posteromedial process (Fig. 25 d ). Cercus short. Surstylus with a very small comb-like row of surstylar bristles ventrally (Fig. 25 a – c ).

Comments.

Previous Chinese records of this species are from Ningxia ( Su and Liu 2009; Su 2011; Dong et al. 2020). Here we present new records from Beijing, Gansu, Hebei, Qinghai, Shaanxi, Tibet, and Yunnan. Females of Terrilimosina parasmetanai have four long posterior setae on S 8 and two pairs of long setae on the hypoproct with narrow anteromedial process (Fig. 25 e, f ).
