Ilimpeika Shcherbakov , gen.n.

TYPE SPECIES. I. humerosa Shcherbakov , sp.n .

DIAGNOSIS. Large cicadas. Tegmen: Costal margin arched over most of its length. Broad area anterior to Sc with very low ridge along midline (C and its continuation) separating precostal and costal areas of subequal width. Sc free, not fused with R medially, prenodal branches sparse. M forked distal to R, forming short stalk with CuA near base; CuA stem convex. RP and MA forked more basally than CuA. Veins in prenodal part much less distinct and close-set than subparallel branches connected with strong crossveins in postnodal part. Hind wing: RP and M forked about wing midlength.

COMPOSITION. Type species.

COMPARISON. Similar to the monotypic Late Permian Ignotala Riek, 1973 from Natal in the large size, the wide precostal area separated by a low ridge, and close-set uparched veins with distinct crossveins in the postnodal part of the tegmen, but the latter genus has the tegmen twice larger with Sc and R connected distally, M forked before R and not forming a short stalk with CuA, and the hind wing with M forked more distally.

ETYMOLOGY. From Ilimpeya River (type locality); gender feminine .
