Eupyrrhoglossum corvus
Similar in general appearance to Perigonia lusca form restituta but distinguishable by the dark grey thorax with dark brown edges and broad median stripe. Distinguishable from Eupyrrhoglossum sagra by the absence of the semitransparent submarginal spot on the forewing and the broader yellow band, with more diffuse edges, on the hindwing upperside. Forewing Rs3 and Rs4 not fused apically. Head and thorax without medial crest. Antenna slender, not at all clubbed, hook quite gradually narrowed; end-segment short, conical, less than three times as long as basally broad. Thorax dark grey, contrasting sharply with the dark brown edges and medial line, these broader than in Eupyrrhoglossum sagra.
Male genitalia: Gnathos with hooks more abruptly curved than in Eupyrrhoglossum sagra. Phallus with a long whip, bearing a number of setae, similar to Perigonia and Nyceryx; three heavy apical setae on the right side, preceded by a small number of irregularly-placed setae; no setae on the left side.
