The stout and spine-like setae on fore coxa are synapomorphies for this group. Its included species can be further distinguished by the presence of a recurved labrum in both males and females (in the Iteaphilinae, the labrum is recurved only in the females of Hormopeza ). Type genus Ragas Walker, 1837 . Description Postpedicel always at most two and a half times as long as broad ( Fig. 6A ). Labrum recurved in both males and females ( Fig. 6D ). Anterior of fore coxa with stout, spine like setae ( Fig. 6A ). Males: tergite 8 slender in shape ( Fig. 6F ); ventral surstylus distinguishable ( Fig. 6G ). Comments The first formal description of this group included the genera Dipsomyia , Hormopeza , Hydropeza , Ragas , and Zanclotus ( Sinclair 2016 ) . In the analysis herein, it is found that this subfamily, excluding Hormopeza , can be distinguished only by a few diagnostic characters. Included genera Ragas Walker, 1837 . Dipsomyia Bezzi, 1909 . Hydropeza Sinclair, 1999 . Zanclotus Wilder, 1982 .
