Rhinophoridae

Small to medium flies, resembling sarcophagids. Metathoracic spiracle with both anterior and posterior fringes small, subscutellum convex but weakly developed, never greatly swollen as in tachinids. Wing vein M usually with a more or less obtuse bend, but almost rectangular in some species with long petiolate cell r4+5, or M ending freely in wing membrane. Lower calypter tongue-shaped or oval, diverging from scutellum. Female ovipositing freely (i.e. not on food source). Larvae endoparasitic in terrestrial isopods. First instar larva with completely reduced labrum and closely adpressed mandibles with anterodorsal teeth or serrations. (Wood 1987, Pape 1998)
