MATERIAL. Holotype PIN, No 1866/8, part and counterpart of forewing fragment;

Ukraine, Lugansk Region, Popasnaya District, left bank of the Lomovatka River, old sandstone quarry in the Kartanash landscape unit 0.8 km SSE of outskirts of Kalinovo village, Lomovatka locality; Upper Carboniferous, Kasimovian Stage, Upper Isaeva Fm.; deposited in the

Borissiak Paleontological Institute, Russian Academy of Sciences ( PIN RAS).

DESCRIPTION. Costal area at RS base narrower than subcostal one; SC with simple and dichotomizing veinlets. RS forked at basal third of wing, with five irregularly pectinate backward branches at distal third of wing. M branching starting from the wing middle length, pectinate forward, with three main branches. CuA forking at its middle length, with

4-branched fore and 5-branched hind branch, and with two posterior branches started within intercubital crossveins. CuP straight behind its middle length. A 1 simple, A 2 with more than two main veins and more than five endings. Crossveins simple in radial and interradial areas,

between RS branches and distal M branches, and between anal veins, Y-like and forming cell rows in subcostal, medial (distally) and intercubital (basally) areas. Hyaline lines crossed with crossveins present between branches of RS and M and in medial area distally. Apices of CuA branches connected with ambient vein running next to wing margin.

MEASUREMENTS. Forewing width 6 mm, length about 16 mm.

DIAGNOSIS. Of the Carboniferous Glaphyrophlebia , the new species is most similar to

G. pygmea (Meunier, 1907) and G. wettinensis (Fritsch, 1899) in having M three-branched,

pectinate forward. It differs from both species in having RS irregularly pectinate, with second basal branch forking basally (in G. pygmea and G. wettinensis RS is regularly pectinate).

ETYMOLOGY. From the Popasnaya District.
