In addition to the characters in the key above, Platypygus is distinguished from other genera of Platypyginae by the combination of following characters: postgena not developed posteriorly as an acute process; mesonotum highly arched; and presence of vein R2+3 at the middle of veins R4+5 and R1 (i. e., its apex equidistant from the ends of each vein). Hull (1973) gave a very detailed description of the genus but unfortunately based it virtually exclusively on Cyrtisiopsis crassirostris Hesse, which has since been transferred to Ahessea.
In our examination of specimens during this study we have noticed a distinct sexual dimorphism in size and color with females normally much larger and darker than males.
