Diagnosis.

Sternite 5 with a densely setulose posteromedial process and short setae (Fig. 9 d ). Surstylus with an anteroventral process (with short anterior process and a sparse comb-like row of bristles at apex) and unmodified posteroventral corner (Fig. 9 a – c ).

Comments.

Terrilimosina deemingi Marshall , newly recorded from China, resembles T. capricornis Su , from which it differs in having a densely setulose posteromedial process and short setae on S 5 (Fig. 9 d ), an anteroventral process (with short anterior process and a sparse comb-like row of bristles at apex), and unmodified posteroventral corner on the surstylus (Fig. 9 a – c ). Terrilimosina capricornis Su has patch of posteromedial setulae and long setae on S 5 (Fig. 7 d ), an anteroventral process (with long anterior process and a dense comb-like row of bristles at apex) and a triangular posteroventral process on the surstylus (Fig. 7 a – c ).
