Distribution


Imago

Wingspan 13–15 mm. Very similar to Dichrorampha flavidorsana, but distinguished by a comparatively broad medio-dorsal blotch on the forewing, a fuscous hindwing that gets slightly paler towards the base and the costal fold of the male reaches to just over one third.
Genital dissection is needed for confident separation of these species.

A brightly coloured moth with a large yellow/orange dorsal patch, plumbeous striae from pale costal strigulae on the terminal half of the costa and with prominent black spots on the termen. There is prominent orange shading around the terminal spots, plumbeous striae and apex. There are black dashes associated with the plumbeous striae.
