This catalogue includes genera and species of Sarcophagidae (Diptera: Calyptratae, Oestroidea) from Argentina. For each species the following information is given: synonyms, geographic distribution, forensic, sanitary and/or veterinary importance, observations, and the most relevant bibliographical references. The species are illustrated with habitus photographs of the adults and male genitalia (which provide the most reliable characters for identification at the species level). The information on the geographical distribution of the species was indicated on maps. Sarcophagidae include small to large fly species (3 -20 mm), mostly gray color with silver or golden pruinosity, presenting longitudinal stripes on the thorax and checked pattern on the abdomen. Females of Sarcophagidae incubate their eggs in a bilobed incubatory pouch and usually deposit first-instar larvae in their breeding substrates. Most species feed and/or breed their larvae in decomposed organic matter, but there are a wide range of life cycles including parasitoids of land snails, kleptoparasites of solitary wasp and myiasis-causing species. Several species are used as forensic indicators or have medical and veterinary relevance as myiasis producers.
