Etymology.
Latin incompletus, “incomplete”.
Holotype.
PIN, no. 5103/286, hindwing (part and counterpart), with cubito-anal area missing.
Paratypes.
PIN, no. 5103/122, incomplete forewing (basal half only), part and counterpart; PIN, no. 5103/123, incomplete forewing (anterior half only, with apex, basal and posterior parts missing), part and counterpart. In addition, two forewing fragments apparently belonging to the same species.
Locality and horizon.
Balymotikha locality, Vyazniki town, Vladimir Province, Central European Russia; uppermost Vyatkian (Upper Changhsingian), Upper Permian.
Description.
Forewing. Anterior margin slightly convex. Costal space somewhat wider than subcostal one. Pterostigma distinct, lanceolate. SC not reaching the pterostigma, bearing one oblique distal branch; connected distally with R1 by short transverse crossvein. R1 sharply curved posteriad at origin of weak distal branch in pterostig mal area. RS forking somewhat before than MA. Thyridium at MP stem before fork. CuA base obscure, presumably curved backwards and located somewhat distal to M5. Crossvein cua-cup slightly sigmoid, distinctly curved backwards. Crossvein pattern typical of genus. Color pattern in form of sparse dark spots, mostly around crossveins.
Hindwing venation and coloration similar to those in forewing. SC slightly shortened, reaching level of RS+MA bifurcation, somewhat beyond wing midlength, forking apically. Pterostigma distinct. R1 nearly straight, turning apically towards anterior margin. R1 branch obscure. CuA distinctly convex along the whole length.
Measurements (mm).
hindwing length of holotype, 9.8; forewing length of paratype PIN, no. 5103/122, 6.1, as preserved; paratype PIN, no. 5103/123, 7.9, as preserved.
Comparison.
The new species substantially differs from others by SC with a single, distally located fore branch.
