Type material.

Male holotype from Dominican Republic, Barahona Province, Cachote Biosphere Reserve, 18.09786N, 71.18925W, 1200 m, 7.vii.2012, team CarBio (NMNH, USNMENT 01747004). One female paratype, same data.

Etymology.

The specific epithet is a noun in apposition meaning wart in reference to the male palpal bulb bearing a wart-like projection.

Diagnosis.

Males can be diagnosed from all species by the wart-like projection on the prolateral side of the bulb (Fig. 14 ); females can be diagnosed by their small heart-shaped posterior receptaculum (Fig. 18 ).

Description.

Male (holotype): Total length: 1.9; carapace length: 0.95; carapace width: 0.79. Cephalothorax: Carapace ovoid; shiny, bright yellow; pars cephalica flat. Sternum yellow; longer than wide; covered entirely with long dark setae. Endites yellow with one large, median backward-pointing projection (Fig. 37 ); labium yellow. Clypeus vertical; short (1/2 × radius of ALE). Chelicerae yellow; promargin and retromargin without teeth; fangs normal, 1/3 the length of the chelicerae. Eyes: Six eyes surrounded by black pigmentation; ALE largest, oval; PME rectangular; PLE smallest, oval; ALE separated by their radius; ALE-PLE touching; PLE-PME touching; PME touching. Abdomen: Oval; light beige covered dorsally with long dark setae; epigastric and postepigastric scuta light yellow, well sclerotized. Legs: Femora with basal half whitish, apical half-light yellow, other legs segments light yellow; tibia I with three pairs of ventral spines, metatarsus I with two pairs of ventral spines; leg formula 4123. Genitalia: Palpal segments yellow; palpal bulb whitish. Palpal patella and tibia with spines prolaterally (Fig. 14 ). Palpal bulb ovoid with apical triangular bump and prolateral wart-like projection (Figs 13 , 14 ); embolus and conductor set on an oval base with apical ridges (Figs 15 , 16 ); embolus well sclerotized, wide and triangular; conductor spine-like, well sclerotized reaching the tip of the embolus (Fig. 16 ).

Female (paratype): Total length: 2.04; carapace length: 0.98; carapace width: 0.76. Cephalothorax: Carapace, sternum, labium and chelicerae: as in male. Endites without projection. Eyes: Same as male. Abdomen: Oval, light beige; epigastric and postepigastric scuta orange, well sclerotized (Fig. 17 ). Legs: Color as in male; leg I missing; all palpal segments with strong spines. Genitalia: Epigynal region not protruding, with small, squared structure visible through the epigastric scutum, and triangular plate visible through the epigastric furrow (Fig. 17 ). Internal genitalia with triangular anterior receptaculum, projecting posteriorly; posterior receptaculum small, bulbous with pore field; wing-like projections not observed (Fig. 18 ).

Other material examined.

Same data as type specimens: 2♂ (UVM).

Distribution.

Dominican Republic, Barahona Province (Fig. 40 ).
