( Figs 195–197 View FIGURES 192–200 )

Oxysarcodexia nitida Soares & Mello-Patiu, 2010: 72   ; Peru, Avispas , Madre de Dios. Holotype male in MNRJ.

Diagnosis. Male. Length 7.0 mm. Postocular plate with pale golden pollinosity. Ocellar bristles well developed. Thorax and abdomen with golden pollinosity, T5 partly with golden pollinosity. Three well-differentiated postsutural dorsocentral bristles posteriorly, although a small bristle can be present among these.Apical scutellar bristles present. Legs blackish. 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 and with pilosity and bristles at apex of arms. Cercus straight in lateral view, with pointed obliquely cut apex. Cercus with bristles ventrally present at proximal half portion. Cerci with distal third narrower than middle part in posterior view; diverging. Pregonite of equal width from base to apex; apex darker than base. Postgonite with expanded base, gradually narrowing to apex; unicolorous. Distiphallus with smooth ventroapical margin, conical apex, straight dorsal outline, lateral lobes and lateroapical expansions. Vesica symmetrical; distal lobes well developed, squared, sclerotized, without spines.

Remarks. This species ( Fig. 196 View FIGURES 192–200 ) is morphologically very close to O. vittata   ( Fig. 279 View FIGURES 274–283 ), with evident differences in the shape and adornment of the vesica (triangular with two lateral projections, the outer one less sclerotized and with scale-like adornment in O. nitida   ), in the shape of the distiphallus apex (without a dorsoapical projection; with serrated margin of ventroapical projection more irregular; and apical corner of the ventroapical projection not as long as in O. vittata   ) and pregonite (without the median process observed in O. vittata   ) (Soares & Mello-Patiu 2010). The holotype male lacks apical scutellar bristles, but these are present in the specimen from Ecuador examined here, so this should be considered intraspecific variation. See also remarks under O. ariozanoi   sp. n. and O. augusta   . Female unknown.

Distribution. NEOTROPICAL. Brazil (Amazonas, Mato Grosso, Mato Grosso do Sul), Ecuador *, Peru.

Biology. Oxysarcodexia nitida   was collected using a “fly trap” baited with rotting beef lung ( Carvalho-Filho et al. 2017).
