Heterusinula dichroa Jordan

Eterusia dichroa Jordan, 1907, Gross-Schmett. Erde, 10: 33.

Diagnosis

This is a small species with the body and wing borders black, the wings otherwise pale yellow as mentioned in the generic account. It could be confused with some lithosiine arctiid species, particularly Pseudoscaptia rothschildi Draudt (Holloway, 2001: 329), but this has the yellow darker, the forewings narrower, and the hindwings are more acute apically. The wing venation also differs considerably.
