This manuscript is submitted to the MYIA series and will be published in MYIA 12. While the basic work for this catalog has been done more than 7 years ago, a thorough review and the formating were done as part of my Smithsonanian fellowship working on the BioSystematic Database of World Diptera.
Wings usually broken off, leaving a short stub; if wing complete, crossvein dm-cu absent. Female with abdominal sternites 1-5 absent; membrane with numerous setiferous sclerotized spots. Consists of 5 species.
Distinguished from occidentalis by the relatively longer surstylus (apical width/total length 0.40) (fig. 6), and by the long paraphysis in lateral view (0.54 greatest width/length). Separated from orientalis by having a wider interocular distance; cheek deeper; abdominal sternites (males) rectangular; abdominal pleural membrane with setulae more numberous in both sexes; female tergites smaller.

The Carnidae are quite small (1-2 mm) black flies and probably due to their small size, they have not attracted a great degree of study. One notable exception is Carnus hemapterus Nitzsch, which is parasitic on birds, and was therefore the centre of several studies. Most species of the Carnidae are saprophagous and are associated with carrion, faeces, or bird's nests. Worldwide there are five genera with 88 extant and two fossil species.
