Melinoessa fulvescens

Melinoessa fulvescens is a species of moth in the family Geometridae, native to Sierra Leone and Gambia. It was described by Dru Drury in 1782 as "Phalaena fulvata", a name which was pre-occupied (see "Cidaria fulvata"). The current, slightly different, specific name was given by L. B. Prout in 1916.
