Saigusa, Toyohei & Sinclair Introduction, Bradley J., 2021, Revision of the Trichoclinocera yixianensis species-group from eastern Asia (Diptera: Empididae: Clinocerinae), Bonn zoological Bulletin 70 (1), pp. 51-65 : 52

Trichoclinocera yixianensis species-group

Recognition. These are very unusual species of Trichoclinocera , characterized by long spine-like setae at the base of the fore femora ( Figs 3–4 ), often one-third to one-half length of the segment; face greatly narrowed, eyes somewhat narrowed, with facets enlarged anteroventrally ( Fig. 2 ), and bacilliform sclerite extending apically beyond base of clasping cercus.

Remarks. Specimens of this group were collected in seepages and small streams with overhead canopy, in contrast to broad streams and rivers which are the usual habitat for Trichoclinocera (see Discussion).
