Mariluis, Pablo Ricardo Mulieri Juan Carlos & Patitucci, Luciano Damián, 2010, Review of the Sarcophaginae (Diptera: Sarcophagidae) of Buenos Aires Province (Argentina), with a key and description of a new species, Zootaxa 2575, pp. 1-37 : 5-7

Key to species of Sarcophaginae known from Buenos Aires Province, Argentina

Species names in square brackets are included on the basis of male specimens only. Blaesoxipha (Acanthodotheca) diloboderi Pape is excluded from the key because its external morphology is unknown. Blaesoxipha (A.) denieri (Blanchard) and Engelimyia bosqui (Blanchard) are excluded from the key because their females are still unknown (only brief notes on male are provided).
