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).
