Type material.

Male holotype from Dominican Republic, La Vega Province, Constanza, Valle Nuevo National Park, 18.84633N, 70.74064W, 2983 m, 26.vi.2012, team CarBio (NMNH, USNMENT 01747000). One female paratype, same data.

Etymology.

The specific epithet is a noun in apposition meaning wings, in reference to the large wing-like structures of the female internal genitalia.

Diagnosis.

Males are diagnosed from all species by the combination of the following characters: constricted tip of palpal bulb and their bent embolus, wider apically, long conductor reaching the tip of the embolus (Figs 2 , 3 ); females are diagnosed by the large, anterior wing-like projections of their internal genitalia and triangular anterior receptaculum (Fig. 5 ).

Description.

Male (holotype): Total length: 1.9; carapace length: 1.0; carapace width: 0.7. Cephalothorax: Carapace ovoid; shiny, bright orange; pars cephalica flat. Sternum yellow; longer than wide; covered entirely with long dark setae. Endites yellow with one elongated and thin apical backward-pointing projection (Fig. 34 ); labium light yellow. Clypeus vertical; short (1/2 × radius of ALE). Chelicerae yellow; promargin and retromargin without teeth; fangs normal 1/3 length of chelicerae. Eyes: Six eyes surrounded by black pigmentation; ALE largest, oval, PME squared; PLE smallest, oval; ALE separated by their radius; ALE-PLE touching; PLE-PME touching; PME touching. Abdomen: Oval; light gray covered dorsally with long dark setae; epigastric and postepigastric scuta light orange, well sclerotized. Legs: Yellow; tibia I with five pairs of ventral spines, metatarsus I with 2 pairs of ventral spines; leg formula undetermined, missing legs II-III-IV. Genitalia: Palpal segments light yellow; palpal bulb whitish. Palpal femur, patella and tibia with spines prolaterally (Fig. 2 ). Palpal bulb ovoid constricted at tip (Fig. 2 ); embolus long, bent medially, wider apically; conductor elongated and thin, wider apically, reaching the tip of the embolus (Fig. 3 ).

Female (paratype): Total length: 1.98; carapace length: 0.94; carapace width: 0.74. Cephalothorax: Carapace ovoid; shiny, bright orange; pars cephalica flat. Sternum, labium and chelicerae: as in male. Endites without projection. Eyes: Same as male. Abdomen: Oval; gray; epigastric and postepigastric scuta orange, well sclerotized (Fig. 4 ). Legs: Color as in male; all legs missing; all palpal segments with strong spines. Genitalia: Epigynal region not protruding, with large structure visible through the epigastric scutum (Fig. 4 ). Internal genitalia with triangular anterior receptaculum, projecting posteriorly into a plate-like extrusion; posterior receptaculum not observed; wing-like projections well sclerotized, tridimensional (Fig. 5 ).

Other material examined.

None.

Distribution.
