Corgatha brumasa Holloway sp. n.

♂ 7mm. The facies is similar to that of the much larger griseicosta but the forewing postmedial is more irregular and curved, punctate with white patches external to each black dot throughout, rather than just the posterior half. The dark grey costal zone encloses several white spots spaced evenly along on the anterior edge. There is a similar postmedial on the hindwing. There are black spots in the spaces at the margins of the wings as in griseicosta. The head is broadly white between the antennae. The male genitalia are similar to those of griseicosta but the costal process of the valve extends to beyond the apex of the cucullus, rather than being slightly shorter.
