Orvasca kilanas sp. n.
Orvasca kilanas 
(holotype) |
 |
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.
