Diagnosis.

Sternite 5 posteriorly with dense long bristles, a basally deep constricted posteromedial lobe (with ~ 5 short robust marginal bristles and tufts of small, flat setulae), and two pairs of bristles (posterior pair thinner) at the base of the posteromedial lobe of S 5 (Fig. 15 d View Figure 15 ). Surstylus with three robust bristles on the internal lobe of the surstylus, five robust ventral tooth-like spines, and one longer robust tooth-like posterior spine (Fig. 15 a – c View Figure 15 ).

Type locality.

Japan, Shikoku, Ishizuchi Mt. National Park, Omogo Valley [700 m].

Distribution.

China (Chongqing, Gansu, Guangxi, Hubei, Xizang, Yunnan); India (Uttaranchal); Japan (Shikoku); Nepal.

Comments.

Terrilimosina longipexa Marshall , newly recorded from China, resembles T. paralongipexa Hayashi , from which it differs in having dense long bristles on S 5, a basally deep constricted posteromedial lobe (with ~ 5 short robust marginal bristles and tufts of small, flat setulae) on S 5, two pairs of bristles (posterior pair thinner) at the base of the posteromedial lobe of S 5 (Fig. 15 d View Figure 15 ), three robust bristles on the internal lobe of the surstylus, and five robust ventral tooth-like spines and one longer robust tooth-like posterior spine on the surstylus (Fig. 15 a – c View Figure 15 ). Terrilimosina paralongipexa Hayashi has sparser short setae on S 5, a basally shallow constricted posteromedial lobe (with tufts of small, flat setulae and a narrow lateral process) on S 5, a pair of bristles at the base of the posteromedial lobe of S 5 (Fig. 23 c, d View Figure 23 ), four robust bristles on the internal lobe of the surstylus, some ventral setae, and one shorter robust tooth-like posterior bristle on the surstylus (Fig. 23 a, b View Figure 23 ).
