Oxysarcodexia plebeja Lopes, 1946c: 142; Mexico, Morelos, Cuernavaca. Holotype male and one male paratype in MNRJ, one male paratype in CNC.
Diagnosis. Male. Length 7.0 mm. Postocular plate with golden pollinosity. Ocellar bristles weakly developed. Thorax with golden pollinosity more intense laterally. Three well-differentiated post-sutural dorsocentral bristles posteriorly, although a small bristle can be present among these. Apical scutellar bristles present. Legs blackish. Abdomen with intense golden pollinosity, T5 with golden pollinosity along the entire extension. T4 with 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 expanded obliquely cut apex. Cercus with bristles ventrally in distal half. Cerci parallel, with apical third of each cercus narrower than middle part in posterior view. Pregonite and postgonite both with expanded base, gradually narrowing to apex; unicolorous. Distiphallus with ventroapical concavity with serrated margin, rounded apex and straight dorsal outline. Vesica symmetrical, with rounded median projection of main branch; distal lobes reduced, with filamentous lateral expansions, tapering, sclerotized; median lobe of the filaments with spines only on ventral surface.
Remarks. The shape of the vesica of O. plebeja (Fig. 232) is very peculiar and different from the more typical leaf-like shape seen in Oxysarcodexia. See also remarks on O. augusta. Female unknown.
Distribution. NEARCTIC. Mexico (Chiapas *, Morelos, San Luis Potosí), USA (Texas). NEOTROPICAL. Colombia, Costa Rica, Mexico (Chiapas *).
Biology. The original description mentions specimens collected in fruit fly traps (Lopes 1946c). At Antioquia, Colombia, in a semi-urban area, this species was collected using chicken viscera and fish heads as bait (Ramírez-Mora et al. 2012).
