Oxysarcodexia meridionalis ( Engel, 1931) View in CoL

( Figs 176–178 View FIGURES 173–181 )

Sarcophaga (Dasyproctia) ventricosa var. meridionalis Engel, 1931: 146 View in CoL ; Argentina, Chaco, San José. Lectotype male (designated by Dodge 1966: 687) in WSU, one male and one female paralectotypes in SMNS (none examined).

Sarcophaga illata Lopes, 1938: 340 View in CoL ; Brazil, Goiás, Campinas. Holotype male in MNRJ.

Diagnosis. Male. Length 9.0–10.0 mm. Postocular plate with golden pollinosity. Ocellar bristles well developed. Thorax and abdomen with golden pollinosity, although slightly silvery ventrally on the abdomen, T5 with golden pollinosity along the entire extension. Two well-differentiated posterior and 2 smaller anterior post-sutural dorsocentrals.Apical scutellar bristles absent. Legs blackish.T3 with 2 pairs of lateral marginal bristles, T4 with 1 pair of median marginal and 3 pairs of lateral marginal bristles. ST5 with deep median cleft with margins almost parallel and with pilosity and bristles at apex of arms. Cercus straight in lateral view, with pointed apex and straight margin. Cercus with bristles ventrally only in distal third. Cerci with distal third narrower than middle part in posterior view; parallel. Pregonite and postgonite both with expanded base, gradually narrowing to apex; unicolorous. Distiphallus with smooth ventroapical margin, rounded apex and sinuous dorsal outline. Vesica symmetrical; distal lobes well developed, mediolaterally expanded, rounded, sclerotized, with spines only on ventral surface.

Remarks. Lopes (1975c) considered O. meridionalis a probable member of the ventricosa group, although he stressed that this cannot be confirmed without study of the female, which is still unknown. The terminalia of O. meridionalis ( Fig. 177 View FIGURES 173–181 ) are similar to those of O. parva ( Fig. 211 View FIGURES 210–218 ), but the cercus of the former is more slender and pointed and the distal lobes of the vesica are larger, completely sclerotized and adorned with spines.

Distribution. NEOTROPICAL. Argentina (Chaco, Delta Del Paraná , San José), Bolivia, Brazil (Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Rio de Janeiro *, São Paulo).

Biology. This species occurs in the Brazilian Cerrado ( Lopes 1973b; Faria et al. 2018; Paseto et al. 2019) as well as in urbanized areas (collected at Campinas, São Paulo state, Brazil, during the present study). It has been collected on a goat carcasses (present study) as well as on pig carcasses exposed in pasture and forest areas of the Brazilian Cerrado, with higher abundance in the dry season ( Faria et al. 2018; Paseto et al. 2019). It has also been collected in Van Someren-Rydon canopy traps baited with rotten bananas, yeast and rotten squid in rural and wild Argentinean wetland areas ( Dufek et al. 2016).
