(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). Surstylus with one robust bristle and an incompact comb-like row of bristles internally (Fig. 17 a – c). 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), one robust bristles and an incompact comb-like row of bristles on internal surface of the surstylus (Fig. 17 a – c). 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), and four robust bristles and a compact comb-like row of bristles on the internal surface of the surstylus (Fig. 23 a, b). 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.
