Type material.

Male holotype from Dominican Republic, La Vega Province, Constanza, Valle Nuevo National Park, 'Jurassic Park’, 18.688N, 70.596W, 2100 m, 26.vi.2012, team CarBio (NMNH, USNMENT 01747001). Two female paratypes, same data.

Etymology.

The specific epithet is a noun in apposition taken from the type locality, Jurassic Park, Dominican Republic.

Diagnosis.

Males are distinguished from all species of the genera by the spatula-shaped tip of the embolus (Fig. 7 ). Females are distinguished by their large funnel-shaped anterior receptaculum (Fig. 9 ).

Description.

Male (holotype): Total length: 1.93; carapace length: 1.03; carapace width: 0.96. Cephalothorax: Carapace ovoid; shiny, bright orange; pars cephalica slightly elevated. Sternum orange; longer than wide; covered entirely with long dark setae. Endites orange with one very small apical backward-pointing projection (Fig. 35 ); labium light orange. Clypeus vertical; short (1/2 × radius of ALE). Chelicerae orange; promargin and retromargin without teeth; fangs long, 2/3 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; beige dorsally covered with long dark setae; epigastric and postepigastric scuta orange, well sclerotized. Legs: Orange; tibia I with five pairs of ventral spines, metatarsus I with two pairs of ventral spines; leg formula 4123. Genitalia: Palpal segments yellow; palpal bulb whitish. Palpal patella, tibia and tarsus with spines prolaterally (Fig. 6 ). Palpal bulb ovoid slightly constricted at tip (Fig. 6 ); embolus long, bent medially with transparent spatula-shaped tip; conductor long and thin reaching the tip of the embolus (Fig. 7 ).

Female (paratype): Total length: 2.12; carapace length: 0.92; carapace width: 0.76. Cephalothorax: Carapace ovoid; shiny, yellow; pars cephalica flat. Sternum and labium light yellow. Chelicerae and endites light yellow, not modified. Eyes: as in male. Abdomen: Oval, light beige; epigastric and postepigastric scuta orange, well sclerotized (Fig. 8 ). Legs: Light yellow; tibia I with five pairs of ventral spines, metatarsus I with two pairs of ventral spines; leg formula 4123; all palpal segments with strong spines. Genitalia: Epigynal region not protruding, with funnel-shaped and rectangular structures visible through the epigastric scutum (Fig. 8 ). Internal genitalia with funnel-shaped anterior receptaculum; posterior receptaculum not observed; wing-like projections well sclerotized, tridimensional (Fig. 9 )
