Type material.

Male holotype from Dominican Republic, La Alta Gracia Province, Occidental, San Rafael, del Este National Park, 18.355536N, 68.6182518W, 46 m, 7-8.vi.2012, team CarBio (NMNH, USNMENT 01747002). One male and four female paratypes, same data (USNMENT 01747003).

Etymology.

The specific epithet is a noun in apposition honoring local arachnologist and CarBio collaborator Aylin Alegre.

Diagnosis.

Males are diagnosed from all Heteroonops by the combination of the following characters: embolus well sclerotized, not spatulated apically; short conductor not reaching the tip of the embolus (Fig. 11 ); females are diagnosed by their inverse triangular anterior receptaculum and large posterior receptaculum (Fig. 13 ).

Description.

Male (holotype): Total length: 1.65; carapace length: 0.79; carapace width: 0.67. Cephalothorax: Carapace ovoid; shiny, light yellow; pars cephalica flat. Sternum light yellow; longer than wide; covered entirely with long dark setae. Endites light yellow with one small apical backward-pointing projection (Fig. 35 ); 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, dorsally covered with long dark setae; epigastric and postepigastric scuta light yellow, not well sclerotized. Legs: Femora whitish; other legs segments light yellow; tibia I with one pair 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. 10 ). Palpal bulb ovoid slightly constricted at tip (Fig. 10 ); embolus well sclerotized, curved with pointed tip; conductor short and pointed not reaching tip of the embolus (Fig. 11 ).

Female (paratype): Total length: 1.89; carapace length: 0.81; carapace width: 0.67. Cephalothorax: Carapace, sternum, labium and chelicerae: as in male. Endites without projection. Eyes: Same as male. Abdomen: Oval; light gray; epigastric and postepigastric light yellow, not well sclerotized (Fig. 12 ). Legs: Color as in male; tibia I with three 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 tulip-shaped structure visible through the epigastric scutum (Fig. 12 ). Internal genitalia with inverted triangular anterior receptaculum; posterior receptaculum large, pouch-shaped, wrinkled with pore field; wing-like projections short (Fig. 13 ).
