Corgatha classeyi Holloway sp. n.

♂, 8mm. This species is similar in size to marshallae but has the ground colour more of a dull greyish red, and the forewing costal zone is very broadly (2-3mm, tapering distad) paler and more of a buff tone. There is a minute, dark discal spot within this, and there are faintly whitish, zigzag postmedials on all wings, that on the forewing oblique from the dorsum and curving round the discal mark to meet the costa at a more acute angle distad. The male genitalia have the valves tongue-like, with an obliquely based, triangular saccular process and no costal spine, though there is a very slight angle on the costal margin at about two-thirds. The saccus is acute at the apex.
