Petrushevskia borisi Martynova, 1958 : 77 (by original designation). Diagnosis . Forewing ovoid with broadly rounded apex; costal area relatively narrow along entire length, all subcostal veinlets simple; RP1 originating relatively close to origin of RP; RP with 10 closely spaced branches; M fork between origin of RP1 and RP2; MA, MP with few branches; CuA with single fork distally; crossveins in radial to mediocubital spaces randomly spaced except for a single outer gradate series; CuP pectinate, with six branches; Al, A2 pectinate, with 3-4 branches; HW unknown. Comments . Makarkin et al. (2014) assumed that this genus may belong to Mesosmylininae . However, it is possible that it belongs to Protosmylinae as CuP is strongly pectinate, CuA has few branches, and crossveins in the radial to mediocubital spaces are largely randomly spaced (with only a single outer gradate series). In contrast, most genera of Mesosmylininae have multiple distinct gradates series throughout the wing.
