Oxysarcodexia mineirensis Souza & Paseto, 2015: 223 ; Brazil, Minas Gerais, Uberlândia. Holotype male and two male paratypes in MNRJ, two male paratypes in ZUEC.

Diagnosis. Male. Length 6.8−8.4mm. Postocular plate with golden pollinosity. Ocellar bristles well developed. Thorax and abdomen with golden pollinosity. Three well-differentiated post-sutural dorsocentral bristles. Apical scutellar bristles absent. Legs dark brownish. T1+2−5 with dorsal and lateral golden pollinosity spots. T1+2−3 with 1 pair of lateral marginal bristles, T4 with 2−3 pairs of lateral marginal bristles and 1 pair of median marginal bristles. ST5 with deep median cleft with margins almost parallel and with a few short, scattered bristles. Cercus sinuous in lateral view, with pointed apex. Cercus with bristles ventrally only in distal third. Cerci with distal third narrower than middle part in posterior view; parallel. Pregonite broader and lighter than the postgonite, almost straight, with rounded apex (“spoon-like”); unicolorous. Postgonite slender and slightly curved on the apical portion, with rounded apex; unicolorous. Distiphallus flower-like, distally membranous, with projections and smooth ventroapical margin, square apex, sinuous dorsal outline, large dorsoapical swelling, ventroapical projections and lateroapical expansions. Juxta with distal margin membranous and slightly folded inward. Vesica symmetrical; distal lobes well developed, slender, oblong, sclerotized, with distal serrated margin.

Remarks. See under O. ariozanoi sp. n., O. augusta and O. favorabilis . Female unknown.

Distribution. NEOTROPICAL. Brazil (Minas Gerais).

Biology. The holotype and paratypes were collected from decomposing pig carcasses in a semi-deciduous Brazilian Cerrado forest ( Souza & Paseto 2015; Faria et al. 2018). Other specimens have been collected in a mesophytic semi-deciduous forest and pasture, being more abundant in the forest and during the dry season ( Paseto et al. 2019)
