DISTRIBUTION: Perigonia passerina moths fly in Brazil; Bolivia: La Paz (750m), Santa Cruz (150-300m); Argentina: Misiones; Paraguay: San Pedro; Cordillera. Perigonia passerina, Río Negro, Argentina, courtesy of Daniel Rojas Lanus.

"P. passerina can be distinguished from P. l. lusca by its smaller size and relatively short forewings, the middle of the outer edge of which is strongly convex. In comparison, P. l. lusca is larger, with more elongate, triangular forewings that have relatively straight outer margins. The difference in wing shape can be clearly seen in the specimens illustrated by d'Abrera ([1987]). Also, the underside of the abdomen of P. passerina is uniform brown, while in P. lusca the anterior half of the abdomen is generally much paler than the posterior half, being the same colour as the hindwing anal patch. This can be difficult to appreciate if the specimen is worn or greasy." Sphingidae of Bolivia.
