Ravinia aureopyga (Hall, 1928)

Sarcophaga aureopyga Hall, 1928: 339 .

Distribution: Neotropical – Argentina (Buenos Aires new record, Córdoba, Entre Ríos, Santa Fe), Brazil (Rio Grande do Sul), Chile (La Araucanía, Maule, Santiago).

Material studied: Buenos Aires: 1 ɗ, La Juanita, Laprida, 1950 (ANLIS); 2 ɗ, 1 Ψ Carlos Casares, C. Casares, II.2007 on faeces, Torretta leg. (ANLIS), 1 Ψ, Bahía Blanca, Bahía Blanca, 1.II.1938 Scott & Birabén leg (MLP).

Remarks: Blanchard misidentified this species as Euravinia lherminieri Robineau-Desvoidy (Blanchard 1942a) . Both R. lherminieri and R. aureopyga have very similar phallic structures. We base our identification (in part) on the distributional information provided by Pape (1996) who reported R. lherminieri from North and Central America and R. aureopyga from South America. Illustrations of the male terminalia can be found in Hall (1928) and Blanchard (1942a). The female was described by Blanchard (1942a) (as Euravinia lherminieri) but not illustrated.

Biology: Ravinia aureopyga was regarded as a coprophagous species by Blanchard (1939).
