Nanosialis gen. n.

Type species.

Nanosialis ponomarenkoi sp. n.

Diagnosis.

Distinct in the long 1mp cell, distal R fork, numerous Sc veinlets, and triangular pterostigma.

Composition.

Type species and Nanosialis bashkuevi sp. n.

Etymology.

Named after Greek nanos (dwarf) and Sialis; gender feminine.

Remarks.

The apparent CuA (probable CuA2) is simple in Nanosialis ponomarenkoi forewing, but bears a terminal fork in Nanosialis bashkuevi hind wing. This may be an element of the fore/hind wing heteronomy, like in many mesoraphidiids ( Mesoraphidia inaequalis, Mesoraphidia pterostigmalis, etc.).
