There are no records of hosts for this genus. Exallopyga is easily distinguished from other genera of Elampini based on the following combination of unique features: axilla slightly produced into the wing fossa; F1–F5 with distinctly elongated distal sensillae; and the aedeagus of male genitalia with submedial spinose lobe ( French 1985 , Lucena & Almeida 2022 ). French (1985) described the genus, revised its species, and provided an identification key and illustrations of diagnostic characters. Only Exallopyga guatemalensis (Cameron) is known from Brazil .
