Cretaconiopteryx gen. nov. (Figs 1–3)

Type species: Cretaconiopteryx grandis sp. nov.

Diagnosis. Large-sized dustywing (forewing length 6.67 mm). Antenna 27-segmented (with 25 flagellomeres); scape about twice as long as wide; flagellomere subquadrate, nearly as long as wide. Forewing relatively broad, length about 2.0× width of median part; costal space with eight subcostal veinlets on distal half; distal part of ScP curved posteriad; distal part of RA curved posteriad and connected with anteriorly curved RP, forming a loop; proximally RP +MA and MP not fused with each other; RP simple, with a ra-rp crossvein; MA simple, with a rp-ma crossvein; three or four crossveins present between RP +MA and MP; MP bifurcated; Cu branched near wing base; CuP proximally zig-zagged; two cua-cup crossveins present; three cup-a1 crossveins; A2 with a long, distally bifurcated anterior branch and a short, strongly curved posterior branch; two a1-a2 crossveins present; distal-most crossveins among longitudinal veins from RA to A2 arranged into a gradate series. Hind wing slightly narrower than forewing; costal space distally with a few subcostal veinlets; a short oblique stem of MA present near wing base; RP simple, distally slightly curved anteriad; MP and CuA separated by distinct membrane; distal-most crossveins among longitudinal veins from RA to CuA arranged into a gradate series. Abdominal plicatures present on segments 3–4.

Etymology. The generic epithet Cretaconiopteryx is a combination of Creta- (meaning Cretaceous) and Coniopteryx (a typical genus name of dustywings). The name is feminine.

Remarks. The new genus is distinguished from all other dustywing genera by the forewing RP +MA originated from R near wing base, the forewing RA and RP distally forming a loop, the proximally zig-zagged forewing CuP, the presence of 3–4 crossveins between forewing RP +MA and MP, the presence of crossveins between RP and MA and between MP 1 and MP 2, and the gradate-like arrangement of distal crossveins.
