Paectes osseotrigona sp. n.

Paectes osseotrigona (paratype)

15-16mm. The species is similar to leucotrigona except the pale zone of the forewing is less rufous, more bone colour, interrupted by faint brown bars on the costa and diffusing away into grey towards the dorsum medially; the posterior margin to the pale area approaches the dorsum at a less acute angle basally; the subapical area just outside the postmedial pale loop is black as in leucotrigona but the black is not broken by an oblique pale line. The patagia are entirely bone colour as on the forewing; they are mostly dark grey in leucotrigona.
