Holotype male in NHMUK (not examined). Diagnosis. Male. Length 10.0 mm. Postocular plate with golden pollinosity. Ocellar bristles weakly developed. Thorax with pale golden pollinosity, abdomen with silvery pollinosity, although some shades of pale golden pollinosity is seen laterally; T5 partly with golden pollinosity. Two well-differentiated posterior and 2 smaller anterior post-sutural dorsocentrals. Apical scutellar bristles absent. Legs blackish. 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 bristles on arms. A distinct cluster of long, hair-like bristles on the ventral surface of abdomen and tibiae is present. Cercus straight in lateral view, with normal (i.e., as broad as median area), obliquely cut apex. 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 and postgonite both with expanded base, gradually narrowing to apex; unicolorous. Distiphallus with smooth ventroapical margin, rounded apex and straight dorsal outline. Vesica asymmetrical, with angular median projection of main branch; distal lobes well developed, oblong, sclerotized, with spines on proximal half of ventral surface and on right margin (more developed than on left margin). Remarks. Oxysarcodexia villosa is one of the eight species of this genus having a distinctly asymmetrical vesica with the left branch reduced in comparison to the right one, which has long spine-like projections laterally ( Figs 276, 277 ). In this species the vesica is greatly developed, substantially surpassing the distiphallus apex in length ( Fig. 275 ). Female unknown. Distribution. NEOTROPICAL. Brazil ( Maranhão , Pará ). Biology. This species has been collected using cow lung as bait ( Sousa et al. 2015 , 2016) and in a mangrove area ( Sousa et al. 2016 ). In the Brazilian state of Maranhão , O. villosa was classified as accidental and rare ( Sousa et al. 2015 ). Material examined. [ ♂ ] Inst.Agronômico do Norte , Belém, Est. Do Pará—Brasil XI-959. L.
