Nedubrovia deformis Bashkuev , sp. nov.

Figs. 2 D; 6F, G.

Etymology. Derived from Latin deformis , “distorted”.

Holotype. PIN, no. 5102/8; forewing (part and counterpart) distorted apically (apex missing).

Locality and Horizon. Sokovka locality, Vyazniki town, Vladimir Province, Central European Russia; uppermost Vyatkian, Upper Permian.

Diagnosis. Differs from congeners in having fore wings widened, MP+CuA fusion rather short due to early separation of MP, SC somewhat shortened, mp–cua crossvein located distal to thyridium.

Description. Forewing widened, with evenly convex anterior margin. Forewing length as preserved 2.82 mm, reconstructed, ~ 3.4 mm; width 1.45 mm. SC slightly shortened, apparently just reaching pterostigmal area, bending backwards at anterior branch located distinctly before level of RS+MA base. Crossvein sc–r located at level of RS+MA fork. RS, MA, and MP1+2 forks strongly distorted due to rock matrix deformation. CuA and MP fused for a short distance, MP separating from CuA quite basally. Free base of CuA strongly oblique, curved. Crossveins weak, mp–cua distal to MP fork (beyond thyridium). Pterostigma and color pattern not preserved.
