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 01747013). Two female paratypes (USNMENT 01747014), same data.

Etymology.

The specific name is noun in apposition taken from the type locality, Constanza Province, Dominican Republic.

Diagnosis.

Both males and females closely resemble H. castelloides Platnick & Dupérré, 2009; males are distinguished by the narrow, elongated palpal bulb and palpal tibia 2 × longer than patellae (Fig. 30 ), ovoid in the later species, and palpal tibia 1.5 × longer than patellae ( Platnick and Dupérré 2009, fig. 242); females are distinguished by their anterior recepetaculum with four branches (Fig. 33 ), five in H. castelloides ( Platnick and Dupérré 2009, fig. 259).

Description.

Male (holotype): Total length: 1.79; carapace length: 0.86; carapace width: 0.72. Cephalothorax: Carapace ovoid; shiny, pale yellow; pars cephalica slightly elevated. Sternum pale yellow; longer than wide; covered entirely with long dark setae. Endites pale yellow, with small apical projection (Fig. 39 ); labium light yellow. Clypeus sligthly protruding; 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 rounded; PLE smallest, oval; ALE separated by their radius; ALE-PLE touching; PLE-PME touching; PME touching. Abdomen: Oval; beige covered dorsally with long setae; epigastric and postepigastric scuta inconspicuous. Legs: Legs missing. Genitalia: Palpal segments pale yellow; palpal bulb whitish. Palpal femora, tibia and tarsus with spines prolaterally (Fig. 30 ). Palpal bulb elongated (Fig. 30 ); embolus strongly bent, pointed apically; conductor long and thin reaching the tip of the embolus (Fig. 31 ).

Female (paratype): Total length: 2.09; carapace length: 0.85; carapace width: 0.72. 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 pale yellow, not well sclerotized (Fig. 32 ). Legs: Legs missing; all palpal segments with strong spines. Genitalia: Epigynal region not protruding, with tree-shaped structures slightly visible through the epigastric scutum (Fig. 32 ). Internal genitalia with anterior receptaculum elongated with four main branches; posterior receptaculum triangular well sclerotized; wing-like projections elongated and narrow (Fig. 33 ).
