Taxonomic notes on dustywings of Aleuropteryginae (Insecta, Neuroptera, Coniopterygidae) from the mid-Cretaceous Burmese amber

Abstract

Two new genera and three new species of the dustywings subfamily Aleuropteryginae are described from the Burmese amber (lowermost Cenomanian, mid-Cretaceous). Cycloconis maculata gen. et sp. nov. is tentatively placed in the tribe Fontenelleini and appears to be closely related to Libanoconis Engel, 2002, but it can be distinguished from the latter genus by the forks of forewing RP + MA and MP subequal in length and the trifurcated hind wing MP. Burmaleuropteryx meinanderi gen. et sp. nov. resembles Garnaconis Perrichot & Nel, 2014 (both genera with unclear placement of tribe), but can be separated from the latter genus by the forewing rp + ma-mp proximad branching point between RP and MA, the presence of forewing cua-cup, and the lack of stiff setae along distal and posterior margins of wings. Achlyoconis jiae sp. nov. is distinguished from Achlyoconis heptatrichia Engel, 2016 by the larger body size, the forewing with four pigmented spots, and the crossvein between RA and RP + MA slightly proximad branching point between forewing RP and MA. Achlyoconis heptatrichia Engel, 2016 is also re-described based on a series of new material, and its male genitalia is described in detail.
