Type material.

Holotype female: Oricuajo, Costa Rica, Biolley and Tristan (MCZ).

Etymology.

This species is named after the type locality, Oricuajo, and is to be treated as a noun in apposition.

Diagnosis.

Females can be separated from other species by the epigynum which has a conspicuous angular median septum located in the center of the epigynal plate, and by the epigynal pockets, and the internal ducts which have two branches (Figs 85-86). Males unknown.
