South Africa . Diagnosis. Length of body. 4.0 mm (male), 4.5 mm (female). Head. Both male and female have a very characteristic head, with fronto-orbital plates enlarged and touching for almost their entire length and covered with small dense setulae. Frons broad, about one-third of head-width. Ocellar setae absent. Eyes small, with sparse hairs. Antenna dark brown, with postpedicel broad and long, reaching oral margin. Arista short, short pubescent. Palpus long, yellow on basal two-thirds and brown on apical third. Gena deep, about 2 times the width of the broad postpedicel. Thorax. Scutum shiny brown with two white dusted presutural lateral areas between the 2 rows of dorsocentral setae. Prosternum bare. Dorsocentrals 2+3. Haltere with knob white. Calypters white. Legs. Brown. Fore tibia without median setae. Mid tibia with 1 submedian posterior seta. Hind tibia with 1 anterodorsal and 1 posterodorsal setae. Arolium and pulvillus not enlarged. Wing. With a dark cloud formed by dense, elongated microtrichia ( Pont and Werner 2003 , fig. 5). Costal spine indistinct. Veins bare. Abdomen. Sternite 1 bare. Remarks. Flies of the genus Xenomyia Malloch, 1921 have many characters that are abnormal for muscids and are restricted to the Afrotropical region. Of the 16 described species, 7 are from South Africa and were keyed by Pont and Werner (2003) , where X. osculata can be identified. The male aedeagus and female ovipositor were first illustrated for Xenomyia by Pont and Werner (2003 , figs 7–11).
