Vladimiretskia nathani gen. et sp. nov. (Diptera, Cecidomyiidae: Porricondylinae, Asynaptini, Vladimiretskiana subtr. nov.) from Eocene Rovno amber with description of their eggs

The new taxа Vladimiretskiana Fedotova et Perkovsky subtr. nov. and Vladimiretskia nathani Fedotova & Perkovsky gen. et sp. nov. are described from a single female. The new species is characterized by eyes that almost completely cover the head, antennae with 16 flagellomeres that possess a short neck and circumfilar sensoria, very short mouth parts with 3-segmented palpi, an unsclerotized costal cell, a short straight vein R5 not reaching the wing apex, simple veins CuA and M4, absence of r-m, ovipositor not telescopic, and cerci with 3-segmented dorsal lamellae. Eggs of the new species are described. The only previously known fossil eggs are of paedogenetic Miastor vlaskini (Fedotova et Perkovsky, 2007) from late Eocene Rovno amber and Krassiloviola geniusloci Fedotova et Perkovsky, 2017 from late Cretaceous Taimyr amber.
