Holotype male in DEI (not examined). Oxysarcodexia aurea : Sousa et al. (2015: 6) , incorrect subsequent spelling of aura Hall, 1937 . Diagnosis. Male. Length 8.0–9.0 mm. Postocular plate with silvery pollinosity. Ocellar bristles well developed. Thorax with golden pollinosity, more intense at humeral region. Two well-differentiated posterior and 1–3 smaller anterior post-sutural dorsocentrals. Apical scutellar bristles absent. Legs brownish. Abdomen dark brown with golden pollinosity, T5 with golden pollinosity laterally. T3 with 3 pairs of lateral marginal bristles, T4 with 1 (weak) pair of median marginal and 2 pairs of lateral marginal bristles. ST5 with deep V-shaped cleft, and with bristles along margins of arms. Cercus straight in lateral view, with expanded apex cut with a concave margin and dorsal subapical barb, which in lateral view may be misinterpreted as a spine-like bristle. Cerci with distal third as broad as middle part in posterior view; separated and diverging. Pregonite slightly curved, of equal width from base to apex; unicolorous. Postgonite with expanded base, gradually narrowing to apex; unicolorous. Distiphallus with smooth ventroapical margin, rounded apex and straight dorsal outline. Juxta “comma-like” in lateral view, i.e., elongate and curved upwards. Vesica symmetrical; distal lobes well developed, rounded and sclerotized and without any spines, although the external margins appear folded, ending in a strong spine-like structure. Remarks. Hall (1937) considered Engel’s (1931) illustrations of “ Sarcophaga sp.? Amesothyrsus chilensis ” to represent a new species, which he named Sarcophaga aura . This species is recognized by the very peculiar cercus, straight in lateral view ( Fig. 37 ) and very slender in distal two thirds in posterior view, strongly different from the general pattern found in the genus ( Fig. 38 ). Female unknown. Distribution. NEOTROPICAL. Bolivia , Brazil (Distrito Federal, Maranhão , Mato Grosso , Mato Grosso do Sul , Minas Gerais ). Biology. This species has been collected from chicken viscera ( Lopes 1980 ), cow lung ( Sousa et al. 2015 , 2016) and exposed pig carcasses in the Brazilian Cerrado (more abundant during the dry period) ( Barros et al. 2008 ; Rosa et al. 2011 ; Faria et al . 2018 ) and Caatinga ( Alves et al. 2014 ). Paseto et al. (2019) collected this species in a pasture area, only in the dry season. In the Brazilian state of Maranhão , O. aura was classified as accidental and rare ( Sousa et al. 2015 ).
