Orvasca kilanas Holloway sp. n.
Diagnosis
♂♂ 9-10mm. The facies has some similarity to that of male Somena similis, but the reddish grey-brown zone of the forewing is paler, with an angled band of yellow more or less medially as illustrated: the boundary between this dark zone and the yellow margin is slightly more irregular and less clearly defined, and there is a fine, curved, yellow fascia just within the dark zone. The genitalia indicate a relationship to the previous two species: the dorsal process of the valve is much shorter, but oriented as in ashleyi. The ventral arm is more as in waterstradti, but with an acute apex and a more strongly curved ventral margin.
