Oxysarcodexia cocais Carvalho-Filho, Sousa & Esposito, 2017: 350 View in CoL View Cited Treatment ; Brazil, Maranhão. Holotype male in MPEG (not examined).

Diagnosis. [Based on the original description by Carvalho-Filho et al. (2017) and on photographs provided by Dr. Pablo R. Mulieri (MACN).] Male. Length 6.7 mm. Postocular plate with silvery gray pollinosity. Ocellar bristles similar to uppermost frontals. Thorax with silvery pollinosity. Two well-differentiated posterior and 2 smaller anterior post-sutural dorsocentrals. Apical scutellar bristles absent. Legs blackish brown. Abdomen blackish with silvery pollinosity. T3 with 1 pair of lateral marginal bristles, T4 with 2 pairs of median marginal and 2 pairs of lateral marginal bristles. ST5 with deep median cleft with margins almost parallel and with the inner lateral margin of arms distally covered with many scattered fine bristles and with spine-like bristles. Cercus slightly sinuous in lateral view, with normal, forward-curved apex (i.e., as broad as median area). Cercus with bristles ventrally absent only on apical third. Cerci with apical third as broad as middle portion in posterior view, diverging, with rounded apex and with a distinct constriction mid length. Pregonite and postgonite with expanded base, gradually narrowing to apex; unicolorous. Distiphallus with hair-like trichiae at ventroapical margin, conical apex and sinuous dorsal outline. Juxta widened in lateral view. Vesica symmetrical; distal lobes well developed, sclerotized, slightly angled, with a pre-apical pointed projection ventrally and pointed dorsal projections, without spines.

Remarks. The main feature separating O. cocais from its congeners is the long surstylus, almost as long as the cercus ( Fig. 74 View FIGURES 70–78 ). Female unknown.

Distribution. NEOTROPICAL. Argentina * ( Formosa *), Brazil (Maranhão).

Biology. Unknown. The holotype was collected in a babassu palm ( Orbignya phalerata Martius ) forest, in an area of rainforest and Cerrado vegetation ( Carvalho-Filho et al. 2017).

Material examined. No specimens were examined directly, but photographs of a specimen from Argentina were provided by courtesy of Dr. Pablo R. Mulieri ( MACN).
