MATERIAL. Holotype forewing PIN 5340 View Materials /2645±; Khasurty , 10 km S of Tsakir, Zakamensk district, SW Buryatia, Russia; Lower Cretaceous.
DESCRIPTION. Forewing 3.4 mm long, moderately elongate (2.0:1), widened up to apex of pterostigma, bluntly rounded apically, tornus well developed. Nodal line present, with ir crossvein and RP bend not far from R fork, and break at base of M stem. Costal margin evenly arched; costal space moderately wide. Base of pterostigma marked with slight RA bend, and its boundary with groove posterior to RA. R+M+CuA dividing at 1/5, R stem at 1/3, and M+CuA at 0.4 wing length. R fork moderately wide basally, acute with gently curved RA. RA x1.5 shorter than RP, curved forwards before apex; RP slightly sigmoidal distally. M+CuA stem x1.7 as long as R stem and subequal to R+M(+CuA). M stem half as long as M2 and x1.5 as CuA stem, M fork long and wide (2.2:1). CuA1 nearly thrice longer than CuA stem or CuA2. Clavus relatively wide, with concave posterior margin; Pcu+1A distally running along the margin and joining it near clavus apex. Veins and membrane slightly darkened.
REMARKS. Distinct from the type species in the presence of nodal line with a supernumerary ir crossvein, longer M fork and blunt wing apex.
