Leucoma bicolorata sp. n.

Leucoma bicolorata

14-15mm. The moth is predominantly white, with very faint compressional banding on the forewing, not as obvious as in impressa. The labial palps and forelegs are a brighter yellow-orange than in impressa and ochripes, with yellow scales also ventral to each eye. The palps protrude beyond the frons. The antennae are diagnostically darker, browner than the yellow-orange areas. In the male genitalia, the valves are moderately symmetric, but developed into narrow, curved arms with a pair of setal spines apically as illustrated. Similar spines are seen in greater numbers at the apices of the much shorter and broader valves of L. cryptadia Collenette from Sri Lanka. In cryptadia the antennae are also darker than the orange areas, but the wings of the male are much deeper, the forewings largely transparent as in species of the next genus.
