(all EMCAU).

Diagnosis.

Sternite 5 with sparse setae, a narrow posteromedial lobe (with tufts of small, flat setulae and a broad lateral process), and two pairs of bristles at the base of posteromedial lobe of S 5 (Fig. 17 d View Figure 17 ). Surstylus with one robust bristle and an incompact comb-like row of bristles internally (Fig. 17 a – c View Figure 17 ).

Type locality.

China, Guangxi, Maoershan [1800 m].

Distribution.

China (Chongqing, Gansu, Guangxi, Guizhou, Hubei, Xizang, Yunnan).

Comments.

Previous Chinese records of this species are from Guangxi ( Su 2011; Dong et al. 2020). Here we present new records from Chongqing, Guizhou, Gansu, Hubei, Tibet, and Yunnan.

Terrilimosina maoershanensis Su resembles T. paralongipexa Hayashi , from which males differ in having sparse setae on S 5, a narrow posteromedial lobe (with tufts of small, flat setulae and a broad lateral process) on S 5, two pairs of bristles at the base of posteromedial lobe of S 5 (Fig. 17 d View Figure 17 ), one robust bristles and an incompact comb-like row of bristles on internal surface of the surstylus (Fig. 17 a – c View Figure 17 ). Terrilimosina paralongipexa Hayashi has denser setae on S 5, a broad posteromedial lobe (with tufts of small, flat setulae and a narrow lateral process) on S 5, a pair of bristles at the base of posteromedial lobe of the S 5 (Fig. 23 c, d View Figure 23 ), and four robust bristles and a compact comb-like row of bristles on the internal surface of the surstylus (Fig. 23 a, b View Figure 23 ). Because of these distinct differences in the male terminalia, we here treat T. maoershanensis as a distinct species from T. paralongipexa , and elevate it to the species level.
