Belongs within: Calliphorinae.
The Melanomyinae are a Holarctic group of blow flies whose larvae, where known, are parasitic on land snails (Shewell 1987).
Characters (from Peris & González-Mora 2004): Parafacials usually setose in upper part, without strong setae in lower part. Thorax coloration often metallic on black background. Prosternum often setulose. Hairiness tending to become reduced in preepisternal, prosternal, metasternal and postalar areas. Thoracic squamula usually bare dorsally (rarely with a small patch of setae). Anepimeron almost or entirely bare below. Ventral setulae on costal vein usually extending beyond fusion with R1. Stem vein (basal section of R) dorsally bare. Apical portion of M generally not sinuous in a smooth curve. Abdomen pruinose, not usually metallic, at most slightly apparently tan, sometimes even spotted with brownish yellow anteriorly and dorsally. Male with aedeagus without denticles on ventral surface of distiphallus; cerci short and wide, hairy. End of oviscapt in female with third tergite and epiproct fused in a structure like a small tongue.
