Neonamasia Aarvik , gen. nov.

Type species: Neonamasia cryptica sp. n.

Description. Head. Scales on frons forming crest; scales on vertex forming two tufts; labial palp 1,5 times diameter of eye. Thorax and appendages. Thorax smoothly scaled dorsally. Male hind tibia with brush of long scales. Forewing termen notched just above middle, between vein M3 and CuA1. Venation similar to that of Namasia monitrix (figured by Diakonoff (1983)). Male genitalia ( Figure 13 ): Tegumen without uncus and socii; gnathos two setose, weakly sclerotised lobes; valva with large, nearly rectangular sacculus, with group of spines between basal excavation and caudal edge; additional cluster of spines on end of distally extended sacculus; neck

of valva short, narrow; cucullus small, narrow, bent ventrally, with numerous stout spines; phallus long, at two thirds from base becoming narrower and sinuous, no cornuti. Female genitalia ( Figure 15 ): Ovipositor short; apophyses anteriores longer than apophyses posteriores; two oval, weakly sclerotised lobes present posterior of ostium; two rounded sclerites on both sides of ostium, together giving the impression of the four wings of a hairstreak butterfly; ductus bursae tubular, sclerotised before ostium, slightly widened after middle, ductus seminalis arises close to ostium; corpus bursae with two horn-shaped signa with broad bases.

Diagnosis. Neonamasia gen. nov. differs from Namasia in the male genitalia by the broad valva with clusters of spines and small cucullus; and in the female genitalia by the presence of rounded sclerites around ostium.
