Figs 9–10 .

MATERIAL. Holotype PIN 1255 /1608±, complete tegmen; Kubekovo near Krasnoyarsk, Emel’yanovo district, Krasnoyarsk Krai; upper Itat Formation , Middle Jurassic (Bathonian).

DESCRIPTION. Tegmen 6.0 mm long, elongate (3.0:1), acutely rounded at apex; postnodal part short (about 1/4 tegmen length); emarginations distal to dSc and at CuA1 very slight. Costal margin convex, more so at base; precostal carina narrow; CP faint, bSc short, high arched. Costal area narrow, with oblique swelling in strigil area, but strigil not detected. RA to dSc more than twice as long as R stem; one weak prenodal R branch before R fork and two strong on RA. RA and anterior M branch with short forks; posterior M branch fused with CuA1 for half of its length. Basal cell very short, closed with short M+CuA anastomosis. CuA stem weak proximally, close to claval furrow; CuA2 crossveinlike. Claval veins close-set and displaced anteriorly, 1A bisinuate. Commissural margin with 10 regularly spaced small tubercles. Narrow marginal membrane posterior to tegmen apex. Tegmen and veins pale; membrane entirely punctate, coarser in postnodal part (appearing almost areolate); veins with bases of setae, larger on RA and claval veins.

ETYMOLOGY. Named after Lyudmila N. Pritykina, a Russian paleoentomologist who collected many fossils at Kubekovo.
