A remarkable new genus of Cretaceous dustywings (Neuroptera: Coniopterygidae) in amber from northern Myanmar Liu, Xingyue Lu, Xiumei Zoological Systematics 2017 42 3 380 389 3VP5 Liu & Lu, 2017 Liu & Lu 2017 [136,326,659,683] Insecta Coniopterygidae Cretaconiopteryx Animalia Neuroptera 2 382 Arthropoda genus gen. nov.   Typespecies:  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 RAcurved posteriad and connected with anteriorly curved RP, forming a loop; proximally RP+MA and MPnot fused with each other; RPsimple, with a ra-rp crossvein; MA simple, with a rp-ma crossvein; three or four crossveins present between RP+MA and MP; MPbifurcated; 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 RAto 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; RPsimple, distally slightly curved anteriad; MPand CuA separated by distinct membrane; distal-most crossveins among longitudinal veins from RAto CuA arranged into a gradate series. Abdominal plicatures present on segments 3–4. Etymology. The generic epithet  Cretaconiopteryxis 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 Rnear wing base, the forewing RAand RPdistally 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 RPand MA and between MP1 and MP2, and the gradate-like arrangement of distal crossveins.
