Identification

The wings of this species are smaller than the wings of all species described to date (except Paraphaenogaster hooleyana, which has a unique venation that distinguishes it from all other Paraphaenogaster). The ratio of different vein segments specific for this species (mcu shape, 2RS + M/3RS ratio, etc.) should also be noted.

Three incomplete wing imprints, assigned by us to this species, are almost of the same size and are very similar in the venation pattern.

Distribution

This taxon was described from Velikaya Kema, Primorye, Russia (Chattian, Oligocene).

Castes

In addition to the holotype, specimen PIN, no. 3136/4, imprints and counter-imprints of the forewing without proximal part, and specimen PIN, no. 3136/362, distal part of the wing.
