Other material examined.

DOMINICAN REPUBLIC: Pedernales: same data as holotype, 1♀, 1p♂, 7 imm. (MNHNSD sel_619, 621-622, 624-629); Boca de la Cañada off Hwy. Pedernales-Oviedo, 17°55'00.5"N, 71°30'03.4"W, 9.X.2006, 64 m, S. Crews, on rocks at night, SCC06_071, 2 imm. (CAS sel_637-638).

Etymology.

This specific epithet comes from the name of the type locality and is to be treated as a noun in apposition.

Diagnosis.

Females can be separated from all others by the genital openings which are are located anteriorly, the epigynal pockets are large, and the rounded posterodorsal fold extends nearly half the length of the epigynal plate (Figs 129-130). Males unknown.
