Eublemma robinsoni Holloway sp. n.

♂♂ 8-12mm. The wings are a medium to dark grey-brown, sometimes with an indigo or vinous tint. The forewing costa is edged a pale bone-white, and there is a conspicuous, straight medial fascia, like that in versicolor and similar species, that is a similar colour, with the grey ground grading darker into it on the basal side. However, on the forewing, this fascia meets the costa more basally than in these species, just beyond the centre, with only a hint of a subcostal angle. The forewing has a whitish submarginal that is shallowly concave distad, close to the margin, and fading away where it approaches the margin at one third from the tornus. The hindwing fringes are paler than the ground in some specimens. The male genitalia have the central process blade-like, the acute apex upwardly falcate. The valve is otherwise narrowly tongue-like except for an obtuse angle on the costal margin level with the base of the central process.
