TYPES: Female holotype from Chile: Región del Maule (VII): Provincia de Curicó: 10 km E Los Queñes, fogging in Nothofagus obliqua, 1000 m , -35.01666°, -70.80000°, May 13, 2004, J.E.

Peck, 1 male paratype deposited in AMNH, PBI_OON 15017; Región del Biobío (VIII): Provincia de Ñuble: 72 km SE Chillán, Termas Road, 1175 m (-36.91667°, -71.50000°), Nov. 16, 1993, to Nov. 25, 1993, Platnick, Catley, Ramírez and Allen, 1 male paratype deposited in AMNH, PBI_OON 42335.

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males resemble those of the other Chilean species with simple male palp (figs. 166A–C, 173H, 174F). The embolus is relatively

shorter than in O. jaiba and the endites are parallel; additionally, the tips of the endites are provided with strong, short projections (arrows, fig. 164G). Females can be distinguished by the length and direction of the anterior apodemes of anterior receptaculum, short and almost at 180°, and by the shape and position of the epigastric

ridges, highly convex and near base of the anterior receptaculum (figs. 170A, 172A, 176E).

MALE (PBI_OON 42335): Total length 1.10.

CEPHALOTHORAX: Labium near triangular, pentagonal. Endites parallel, with small projection at tip (fig. 164G). LEGS: Only right legs II, III, left leg IV present. GENITALIA: Bulb without apophyses, long; sperm duct slightly coiled (figs. 166A–C, 173H, 174F).

FEMALE (PBI_OON 2307): Total length 1.25.

CEPHALOTHORAX: Labium rectangular.

GENITALIA: Epigastric region with external pockets, well-developed epigastric ridges near median area, internal pockets absent; anterior receptaculum rounded at tip, lumen with three chambers, anterior apodemes short; posterior receptaculum absent, posterior apodeme formed by entire plate (figs. 170A, 172A, 176E).

DISTRIBUTION: From Región Metropolitana de Santiago (XIII) to Región del Biobío (VIII) to, Chile (map 30).
