description: Genus Platypygus Loew
Platypygus Loew, 1844: 127. Type species: Platypygus chrysanthemi Loew, 1844, by monotypy.
Platypygus is distinguished from other genera of Platypyginae by the combination of following characters: postgena not developed as an acute process; mesonotum highly arched; discal cell closed and presence of vein R2+3 at the middle of veins R4+5 and R1 (i.e., its apex is equidistant between the end of both veins).
Key 1 to species of the genera Platypygus and Cyrtisiopsis known from Iran
1. Postgena extending posterior as an acute process (Fig. 9 a), br cell equal to bm cell (Fig. 9 d)..................................................................................... Cyrtisiopsis maculiventris (Loew, 1874), comb. nov. - Postgena normal, at most with minute blunt process (e.g. Figs. 1 a, b); br cell longer than bm cell (Figs. 1 j, 3d, 6f)..........
1. Although the species P. lativentris and P. chrysanthemi do not occur in Iran, to show differences between them and the new Iranian species, we included both in the key.

5. Mesonotum with two black spots next to transverse suture; black median stripe on mesonotum mostly reaching to scutellum (Fig. 1 c); abdominal tergites with fine and long pale hairs; male genitalia huge and well exposed (Fig. 1 g); spermathecal reservoirs acorn-shaped, with an obvious cap (Fig. 2 g).........................

P. melinoproctus Loew, 1873
