Described from the unique holotype (30 Jan 1968).

This species has somewhat the coloring of the subspecies aporrhegma but the banding of forewing is clearcut in ochroma and not broken as in the former. The harpe of ochroma is narrower and longer than that of aporrhegma and the costa is not as highly arched.

Dichelopa ochroma is a species of moth of the family Tortricidae. It is found on the Marquesas Archipelago in French Polynesia.
