The Sarcophagidae family (belonging to the Sarcophagaidea Superfamily of the Muscomorpha INfraorden), encompasses those commonly known as flesh flies. It is a cosmopolitan family that contains about 3000 species grouped in 173 genera (Pape and collaborators 2011).

This family includes robust gray and black flies, ranging in size from 8 to 14 mm in length. Adult flies have three black lines on the scutum, a concave subscale and an abdomen that generally has squares, lines, bands or spots (Shewell, I987 and Pape, 1996, 1998). All females are viviparous or ovoviviparous and deposit the first instar of their larvae in hosts or some means (Shewell, 1987; Dahlem, 1991).

Meat flies are saprophagous and of great importance for the decomposition of animal matter. Therefore, they are of forensic importance, especially when they prefer advanced stages of decomposition (Carvalho & Linhares 2001). Some species are attracted to excrement and others have caused miiasis in man and domestic animals (Guimarães and Papavero 1999).

I have already commented on more than one occasion that this Family Sarcophagidae is divided into three easily differentiable subfamilies that are Miltogramminae, Paramacronychiinae and Sarcophaginae, (Pape, 1990, 1996).

Miltogramminae are small to medium-sized flies with broad lower calipers and an oval or slightly tapered abdomen (Pape 1996). They usually have a bare or micropowdered edge and a scutum of almost uniform color or with poorly distinguishable stripes (McAlpine 1981, Shewell, 1987). The great majority of the Miltogramminae are Kleptoparasite flies of solitary bees and wasps (Ferrar, 1987). As an example of Miltogramminae I put Miltogramma taeniata.

Sarcophaginae are mostly larger and more robust species, usually with a uniform color pattern. His thorax is gray with three or more blackish stripes and a checkered abdomen (Pape, 1996). Species of this subfamily also have a feathery ridge (McAlpine, 1981; Pape, 1998a). According to Pape (1996), most species within the genus Sarcophaga are predators of dead insects, snails or vertebrates smaller. Morphologically Sarcophaginae members are difficult to separate based solely on external characters, but can be successfully identified after careful analysis of male genitalia (de Carvalho and Mello-Patiu 2008). Male terminals, especially the phallus, are highly distinctive at the species level and have long been used for the recognition of these (Roback, 1954). As an example of Sarcophaginae I spoke of the genus Blaexosipha and showed a species.

There are several competing generic classifications within Sarcophaginae (Downes, 1965, Lopes, 1969, 1982b, Verves, 1986, Shewell, 1987, Povolný and Verves, 1997), most of which were based on regional faunas and were not tested by cladistic analyzes. The classification of Pape (1996) included all the described species of the family but its concept of large genera, sometimes with many subgenera, is not shared by other researchers of Sarcophagidae (eg, Povolný and Verves, 1997; Peris, González Mora and Mingo, 1998).

The following is the classification proposed by Salvador V. Peris † and Dolores González-Mora, Department of Zoology and Physical Anthropology, Faculty of Biology, Universidad Complutense de Madrid, in 2009

Sarothromyiini tribe (= Sarcophagulini)

For some, divided into three groups: Raviniina, Oxysarcodexiina and Dexosarcophagina. For them in two subtribes: Raviniina and Oxysarcodexiina Protodexiini tribe (= Tephromyiina Townsend, 1912; Blaesoxiphina Rohdendorf, 1965; Impariina Roback, 1937; Gesneriidae Villeneuve, 1908; Myiorhinina Townsend, 1931; and Servaisiina Roopa, 1937) Pape groups all genera in Blaexosipha
Lopes recognizes two subtribes: Acanthodothecina and Protodexiina Sarcophagini tribe

Heteronychia Brauer & amp; Bergenstamm, 1889

Sarcophaga (Heteronychia) haemorrhoa Meigen, 1826

The biological behavior of Heteronychia is still little known although many of the species belonging to the group appear to be parasites of terrestrial snails (Coupland & Barker 2004) a strategy that some authors recognize as obligatory (Povolný & Verves 1997) is not optional.

The species of the Iberian Peninsula have been reviewed by PERIS, GONZÁLEZ-MORA and MINGO (1994c, 1996, 1998 and 1999b) and PERIS, GONZÁLEZ-MORA, MINGO and RICHET (1996).
