Rhesala nigricans Snellen 

Heterocgramma nigricans Snellen, 1880, Tijdschr. Ent

Diagnosis

This is a much smaller species than imparata, with a more obtusely angled and transverse forewing postmedial, set more distally, as is that of the hindwing. The male genitalia are characterised by an unusually short and broad uncus and narrow, tongue-like valves with a similarly elongate and semidetached saccular portion.

Taxonomic note

The facies and male genitalia of the taxa brought into synonymy are identical.

Geographical range

Sulawesi, Borneo.
