Sarcophaga xanthosoma Aldrich, 1916: 274 ; Guatemala, Los Amates. Holotype male in USNM (not examined).

Diagnosis. Male. Length 7.0–9.0 mm. Postocular plate with pale golden pollinosity. Ocellar bristles weakly developed. Thorax and abdomen with intense golden pollinosity. Two well-differentiated posterior and 1–3 smaller anterior post-sutural dorsocentrals.Apical scutellar bristles present. Legs blackish. T3 with 3 pairs of lateral marginal bristles, T4 with 1 pair of median marginal and 2 pairs of lateral marginal bristles. ST5 with deep median cleft with margins almost parallel and with pilosity. Cercus straight in lateral view, with expanded obliquely cut apex. Cercus with bristles ventrally absent only on middle portion. Cerci with distal third narrower than middle part in posterior view; diverging. Pregonite with expanded base and sudden narrowing at apex, which is darker than base. Postgonite with expanded base, gradually narrowing to apex; unicolorous. Distiphallus with smooth ventroapical margin but with a small serrated area ventromedially, rounded apex and sinuous dorsal outline. Vesica symmetrical, with lateral lobes and rounded median projection of main branch; distal lobes well developed, with short filaments, tapering, sclerotized, with spines only on ventral surface.

Remarks. Morphological variation seen in O. xanthosoma can lead to confusion with O. amorosa and O. similata ; see remarks under O. amorosa . The female of O. xanthosoma has an undivided T7 ( Tibana & Mello 1985).

Distribution. NEARCTIC. Mexico (San Luis Potosí, Sonora). NEOTROPICAL. Argentina (Misiones), Brazil (Amapá, Amazonas, Ceará, Espírito Santo, Mato Grosso, Minas Gerais, Pará, Paraná, Rio de Janeiro, Roraima, São Paulo), Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Guyana, Mexico (Jalisco, Veracruz), Panama, Peru.

Biology. This species was reared in the laboratory by Lopes (1973b), who did not state the medium, and on human feces by D’Almeida (1994). It has been collected using human feces, peccary entrails, rotten liver, dead fish, pig and rat carcasses, rotten banana mixed with brown sugar, and rotten S. comosa as bait ( Curran & Walley 1934; Lopes 1973b, 1975a; Oliveira et al. 2002; Leandro & D’Almeida 2005; Barbosa et al. 2009; Rosa et al. 2011; Vairo et al. 2011, 2014; Carmo et al. 2017). Oxysarcodexia xanthosoma occurs in urban and periurban habitats (including a zoo), forest and mountainous areas, rainforest fragments, and in the Brazilian Cerrado ( Lopes & Tibana 1982; D’Almeida 1994; Oliveira et al. 2002; Rosa et al. 2011; Vairo et al. 2011, 2014; Carmo et al. 2017).
