Oxysarcodexia petropolitana Lopes, 1973b: 286 . Nomen nudum.

Oxysarcodexia petropolitana Lopes, 1975c: 471 ; Brazil: Rio de Janeiro. Holotype male, allotype, 109 male paratypes and 99 female paratypes in MNRJ.

Diagnosis. Male. Length 9.0–12.0 mm. Postocular plate with golden pollinosity. Ocellar bristles weakly developed. Thorax with golden pollinosity. Two well-differentiated posterior and 3 smaller anterior post-sutural dorsocentrals. Apical scutellar bristles absent. Legs brownish. Abdomen with silvery pollinosity, although with some shades of pale golden pollinosity visible laterally; T5 partly with golden pollinosity. 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, arms triangular at apex and with scattered pilosity on arms. Cercus straight in lateral view, with normal apex (i.e., as broad as median area) and concave margin. Cercus with bristles ventrally only in distal third. Cerci with distal third as broad as middle part in posterior view; parallel and with a distinct constriction mid length. Pregonite with a mediobasal “thorn-like” projection, expanded base gradually narrowing to apex; unicolorous. Postgonite with expanded base and sudden narrowing at apex; unicolorous. Distiphallus with smooth ventroapical margin, rounded apex and sinuous dorsal outline. Vesica symmetrical, with rounded median projection of main branch and lateral lobes; distal lobes well developed, sclerotized, with filaments, tapering, with basal portion enlarged, apex pointed backwards and spines only on ventral surface.

Remarks. See under O. insolita . The female of O. petropolitana was described by Lopes (1975c), who mentioned reddish sternites and T7 with golden pollinosity and divided into two plates; this last character state was also pointed out by Tibana & Mello (1985).

Distribution. NEOTROPICAL. Brazil (Minas Gerais, Rio de Janeiro, Santa Catarina , São Paulo), Ecuador.

Biology. Reared on human feces and on meat by Lopes (1973b, 1975c), but no further details of its development were reported. Collected from human feces ( Lopes 1973b).
