Sinosmylus Yang, 1992

( Fig. 23 )

Type species. Sinosmylus hengduanus Yang, 1992: 450 (by original designation).

Diagnosis. Wings elongate, ovoid; FW extensively mottled infuscate; HW mostly hyaline except for pterostigma, wing margin and wing base; FW subcostal veinlets forked near wing margin distally, some veinlets forked at base, interlinking crossveins absent; RP diverging from RA close to wing base, FW RP1 originating close to origin of RP; RP with two distinct gradate series present in both wings, other crossveins largely absent, resulting in elongate radial cells; FW M vein forked slightly beyond origin of RP1; multiple crossveins present between MP and CuA in FW and CuA and CuP in both wings; female genitalia with spermathecae ovoid; male genitalia not known.

Comments. Sinosmylus is unique among Osmylinae for the scarce RP crossveins besides the gradate series. Hitherto no new material is collected except for the only one female specimen of the type species from southeastern China.
