Parasyntexis khasurtensis Kopylov , sp. nov.

( Fig. 2 A–B)

Etymology. The species name is derived from type locality Khasurty.

Material. Holotype PIN 5340 /2178, part without counterpart imprint in mudstone. Imago , female. Head , thorax and legs not preserved; abdomen segmentation not distinguishable; one fore and two hind wings and ovipositor well preserved. Khasurty ; Russia, Transbaikalia; Lower Cretaceous.

Description. Body dark, wing veins somewhat paler; wings membrane with color pattern: cell 2r and membrane along 1-M—1-Cu—1cu-a, 1m-cu—3 Cu in fore wing darkened, hind wing with broad dark belt from the middle of r cell to the apex of a cell. Fore wing with costal area 2.5 × as wide as C vein; 1-R1 1.25 × as long as pterostigma; pterostigma 3.6 × as long as wide with 2r-rs joins it at its midlength; 1r-rs 1.3 × as long as 2r-rs; cell 2r 1.2 × as long as wide; cell 3r 3.2 × as long as wide; 1-Rs curved basally, 2.2 × as long as 1-M; 1-Rs+M meets 1-Rs without significant bend; cell 2+3rm 3.1 × as long as wide; 4+5-Rs 3.7 × as long as 3-Rs and 1.8 × as long as 6-Rs; 3+4-M 1.4 × as long as 5-M; cell 1mcu 1.8 × as long as wide; 1-Cu very short, just 0.3 × as long as 2-Cu. Hind wing with 2-Rs strongly curved upwards in distal part, meeting R1 at right angle; 1-M with sharp bent in middle, with a short stub directed towards wing base (this stub obviously corresponds with flexion line); 2-Rs 1.2 × as long as r-m 1.2 × as long as m-cu. Ovipositor full length equals 0.83 × fore wing length, part protruding beyond apex of abdomen equals 0.35 × fore wing length.

Measurements: fore wing length 11.3 mm, width 4.4 mm; metasoma length 8.3 mm; ovipositor length: full— 9.4 mm, protruding beyond abdominal apex part—4.0 mm.
