Oxysarcodexia berlai Lopes, 1975

(Figs 48–50)

Oxysarcodexia berlai Lopes, 1975c: 473; Brazil, Pará, Belém, Utinga. Holotype male and 24 male paratypes in MNRJ.

Diagnosis. Male. Length 8.0–9.0 mm. Postocular plate with pale golden pollinosity. Ocellar bristles weakly 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 present. Legs brownish. Abdomen grayish with golden pollinosity, T5 with golden pollinosity. T3 with 1 pair 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 pilosity and bristles on distal half of arms. Cercus straight in lateral view, apex expanded and with straight margin. Cercus with bristles ventrally absent only on middle portion. Cerci with distal third narrower than middle part in posterior view; diverging. Pregonite with expanded base and sudden narrowing at apex; unicolorous. Postgonite with expanded base, gradually narrowing to apex; unicolorous. Distiphallus with ventroapical concavity with serrated margin, rounded apex, lateroapical expansions and sinuous dorsal outline. Vesica symmetrical, with rounded median projection of main branch; distal lobes well developed, with filaments, tapering, sclerotized, with spines only on ventral surface.

Remarks. The main difference between O. berlai and O. ventricosa are: the arrangement of the cerci in posterior view, parallel in the former and diverging in the latter (Lopes 1975c) (Figs 50, 273); the shape of the distiphallus (Dodge 1966), apically more conical in O. ventricosa (Fig. 272) and with a rugose texture of the juxta not observed in O. berlai (Fig. 49); and the blackish legs in O. berlai (Fig. 48) versus yellow in O. ventricosa (Fig. 271). See also remarks under O. amorosa. Lopes (1975c) pointed out that O. berlai probably belongs in the ventricosa group, but corroboration of this hypothesis is hampered by the lack of information on the female, which is unknown.

Distribution. NEOTROPICAL. Brazil (Amapá *, Maranhão, Pará, Pernambuco), Colombia, Peru *.
