Oxysarcodexia major Lopes, 1946 (Figs 170–172) Oxysarcodexia major Lopes, 1946b: 88; Brazil, Rio de Janeiro, Trapicheiro, Distrito Federal. Holotype male, female allotype, 27 male paratypes and 16 female paratypes in MNRJ. Diagnosis. Male. Length 10.0–12.0 mm. Postocular plate with golden pollinosity. Ocellar bristles weakly developed. Thorax and abdomen with intense golden pollinosity, more evident laterally; T5 partly with golden pollinosity. Two well-differentiated posterior and 1–3 smaller anterior post-sutural dorsocentrals. Apical scutellar bristles present. Legs blackish. T3 with 2 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 scattered pilosity and bristles on arms. Cercus sinuous in lateral view, with expanded obliquely cut apex. Cercus with bristles ventrally absent only on the middle portion. Cerci with distal third as broad as middle part in posterior view; parallel and with a distinct constriction mid length. Pregonite with expanded base and sudden narrowing at apex, which is darker than base. Postgonite like pregonite, except unicolorous. Distiphallus with serrated ventroapical margin, rounded apex and straight dorsal outline. Vesica symmetrical, with angular median projection of main branch; distal lobes well developed, elongate, with filaments, tapering, sclerotized, with spines only on ventral surface. Remarks. See under O. insolita. The female of O. major has an undivided T7 (Tibana & Mello 1985). Distribution. NEOTROPICAL. Brazil (Amazonas, Amapá, Bahia, Mato Grosso, Minas Gerais, Rio de Janeiro, Roraima), Colombia, Ecuador, El Salvador, Mexico (Veracruz), Peru, Trinidad and Tobago (Trinidad). Biology. This species has been collected with the use of human feces, rotten S. comosa, rotten banana mixed with brown sugar, rotten liver, rotten beef lung, pig carcasses, chicken viscera and fish heads as bait (Lopes 1973b; Oliveira et al. 2002; Sousa et al. 2011; Ramírez-Mora et al. 2012; Valverde-Castro et al. 2017; Faria et al. 2018; Lopes et al. 2018; Paseto et al. 2019). Collecting methods included W.O.T., Malaise, Shannon and Van Someren-Rydon traps (Lopes & Tibana 1991; Oliveira et al. 2002; Sousa et al. 2011). Its occurrence has been reported from urban (Oliveira et al. 2002; Ramírez-Mora et al. 2012), rural (Ramírez-Mora et al. 2012), and forest areas (Valverde-Castro et al. 2017), in the Amazon forest (Sousa et al. 2011), in the Atlantic forest (Lopes et al. 2018) and in a pasture and a forest of the Brazilian Cerrado (more abundant in the dry season) (Faria et al. 2018; Paseto et al. 2019). Lopes et al. (2018) reported O. major as associated with the putrefaction and dry decay stages of decomposition of pig carcasses. Oxysarcodexia major has been reared under laboratory conditions (Lopes 1973b), but no detailed information about its development exists in the literature. Type material examined.
