Distribution. China ( Gansu *, Ningxia ). Diagnosis. Karny’s (1934) description of Tachycines (Gymnaeta ) brevicauda suggests that it is very close to Tachycines ( Gymnaeta ) coomani , but obviously differs in body size. This species was synonymized by Storozhenko, 1990 with Tachycines ( Gymnaeta ) coomani Chopard, 1929 . Here we consider that these two species should be regarded as two independent valid species for the differences in body size, subgenital plate of female and male genitalia.
