Genus Cratotabanus

Diagnosis.

Cratotabanus isdistinguished from modern tabanids by veins M1, M2, and M3 long, with lengths of M1 approximately the same as that of cell d (vs. 0.5 - 0.7 × length of cell d in Recent Tabanidae ); R5 only slightly deviated from the path of vein R4+5 (in most Recent tabanids, excepting Chrysops Meigen 1803, R5 curved strongly downward). Distinguished from some Cretaceous Tabanidae , as follows: Eotabanoid Mostovski et al. 2003 and Yixian Formation genera with longer R1 (reaching well past level of apex of cell d); fork of R4+5 in Eotabanoid , Palaepangonius Ren, 1998, and Eopangonius Ren 1998 much longer (about equal in length to vein M1).
