Type: Male holotype from Chile: Región de Valparaiso (V): Provincia de Quillota: Parque Nacional La Campana, Sector Granizo, Cajon La Opositora, 545 m, -32.98016°, -71.12833°, Nov.

29, 2002, to Dec. 29, 2002, Thayer, Newton, Solodovnikov, Clarke, Chani, deposited in FMNH 34840, PBI_OON 10557.

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 copulatory bulbs but can be distinguished by the presence of a projection on base of the embolus, absent in other species, and by the notched endites (figs. 164D, 166G–I, 173D, 174C).

MALE (PBI_OON 10557): Total length 1.20.

CEPHALOTHORAX: Labium near pentagonal, borders slightly more sclerotized than sternum. Endites anteriomedian part notched (fig. 164D).

ABDOMEN: Dorsum soft portions white, round.

GENITALIA: Bulb with one curved projection at base; sperm duct slightly coiled (figs. 166G–I, 173D, 174C).

FEMALE: Unknown.

DISTRIBUTION: Known only from the type locality in Chile (Quillota, fig. 178D, map 30).

OTHER MATERIAL EXAMINED: None.
