Eublemma rosearcuata Holloway sp. n.

♂♂ 11-13mm. There are some similarities in facies with betarosea, particularly the brown markings of the hindwing, though the medial band is more definite, strongly arcuate. The medials on both wings separate a more distal pink area from a whitish basal area. The medial of the forewing is angled subcostally. The costa is not broadly white as in betarosea, and the subapical brown mark is much reduced, less oblique. The genitalia have valves that expand to a rather spatulate and rounded apex, and the central process is relatively long and narrow with a slight hook apically. The saccus is broad.
