Oxysarcodexia notata Soares & Mello-Patiu, 2010: 74 ; Peru, Avispas , Madre de Dios. Holotype male in MNRJ.

Diagnosis. Male. Length 7.0 mm. Postocular plate with golden pollinosity. Ocellar bristles well developed. Thorax and abdomen with golden pollinosity, T5 with golden pollinosity along the entire extension. Three welldifferentiated post-sutural dorsocentral bristles posteriorly, although a small bristle can be present among these. Apical scutellar bristles present. Legs brownish. 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 scattered pilosity and bristles on arms. Cercus straight in lateral view, with pointed obliquely cut apex. Cercus with bristles ventrally absent only on the middle portion. Cerci with distal third narrower than middle part in posterior view; diverging. Pregonite and postgonite both with expanded base, gradually narrowing to apex; unicolorous. Distiphallus with serrated ventroapical margin, square apex, sinuous dorsal outline, ventroapical projections, lateral lobes and lateroapical expansions. Vesica symmetrical, with rounded median projection of main branch; distal lobes well developed, rounded, with filaments, tapering, sclerotized, with micro-spines on both dorsal and ventral surfaces.

Remarks. The male terminalia of O. notata ( Fig. 199 ) are similar to those of O. xon ( Fig. 288 ) as already pointed out by Soares & Mello-Patiu (2010). Differences between these two species are in the morphology of the vesica distal lobes (rounded and presenting inner projections with micro-spines in O. notata , and with filaments, tapering, without inner projections or micro-spines, in O. xon ) and distiphallus (with lateral projections folded laterally and with smooth ventroapical margin in O. notata , with small lateral projections and serrated ventroapical margin in O. xon ). See also remarks under O. ariozanoi sp. n. and O. augusta . Female unknown.
