Grandosmylus Makarkin, 1985

Type species. Grandosmylus centrasius Makarkin, 1985: 41 (by original designation).

Diagnosis. Female forecoxae with strongly curved processes; wings elongate ovoid; FW largely hyaline and veins uniformly pale-brownish; subcostal veinlets mainly forked, without interlinking crossveins; RP with 9–10 branches, some of them deeply forked; RP branches only slightly sinuous distally; crossveins numerous in basal half of radial area, inner gradate series absent, outer series present; M vein forked slightly distal to origin of RP1; CuA, CuP, A1 strongly pectinate; branches of A1 long, without interlinking crossveins; male genitalia with large gonarcus bearing a pair of very long dorsal processes, each terminating in paired acute denticles; female genitalia sternite 8 very short with paired short processes.

Comments. This genus is distributed in mountains of Central Asia (at elevations up to 3800 m). Like Parosmylus , it lacks an inner gradate series and can be differentiated by male genitalic features, especially the enlarged dorsal processes on the gonarcus.
