Oxysarcodexia carvalhoi Lopes, 1946b: 92; Brazil, Minas Gerais, Cordisburgo. Holotype male and female allotype in MNRJ, one male and one female paratype in MNR, one male paratype in NHMUK.
Diagnosis. Male. Length 7.0–9.0 mm. Postocular plate with golden pollinosity. Ocellar bristles weakly developed. Thorax with golden pollinosity, more intense laterally at humeral region, as well as on the abdomen, where it is more evident laterally on T4, and on the entire extension of T5. Two well-differentiated posterior and 1–3 smaller anterior post-sutural dorsocentrals. Apical scutellar bristles present. Legs blackish. T3 with 2 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 with dorsal outline sinuous in lateral view, with expanded obliquely cut apex and dorsal subapical barb; with bristles ventrally only in distal third. Cerci with distal third narrower than middle part in posterior view; diverging. Pregonite and postgonite both with expanded base, gradually narrowing to apex; unicolorous. Distiphallus strongly concave ventroapically, with smooth ventroapical margin, a lateroapical furrow, ventroapical projections, conical apex and straight dorsal outline. Vesica symmetrical, with rounded median projection of main branch; distal lobes reduced, with filaments, tapering, sclerotized, with lateral lobes and spines only on ventral surface.
Remarks. See under O. admixta. The female of O. carvalhoi has an undivided T7 (Tibana & Mello 1985).
Distribution. NEOTROPICAL. Brazil (Amapá, Amazonas, Ceará, Espírito Santo *, Mato Grosso, Mato Grosso do Sul *, Minas Gerais, Pará, Rio de Janeiro, São Paulo), Ecuador, Guyana.
Biology. This species has been collected using various baits such as human feces, chicken viscera, mouse and rat carcasses, pig carcasses, fish, and banana mixed with brown sugar (Lopes 1975a; Dias et al. 1984c; Moretti et al. 2008; Rosa et al. 2011; Vairo et al. 2014; Faria et al. 2018; Paseto et al. 2019). Human feces and mouse and rat carcasses have been used to rear this species under natural conditions (Lopes 1973b; Moretti et al. 2008). In the laboratory, O. carvalhoi has been reared on agar plus powdered milk, developing from first instar to adult in 14–17 days (Lopes 1973b). The species has been reported from the Brazilian Cerrado (Rosa et al. 2011; Faria et al. 2018), humid tropical rainforest (Vairo et al. 2014), secondary forest (Moretti et al. 2008), mesophytic semi-deciduous forest and pasture (Paseto et al. 2019) and urban areas (Souza, unpublished).
