TYPES: Female holotype from Chile: Región de La Araucanía (IX): Provincia de Malleco: P.N. Nahuelbuta, Pichinahuel exit, fogging in Arau- caria araucana, 1182 m, -37.80473°, -73.03520°, Dec. 06, 2001, E. Arias et al., deposited in CAS 9023354, PBI_OON 2304 ; same data, 1 male and 1 female paratypes deposited in CAS 9023362, PBI_OON 2308 ; same data, Nov. 22, 2004, J.E. Barriga, 1 male paratype deposited in CAS 9023360, PBI_OON 2309 .
ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.
DIAGNOSIS: Males are very similar to those of O. granizo , O. curico , O. jaiba , and O. quenies in the shape of copulatory bulb. They can be distinguished from those of O. curico by the shape of endites, slightly more pointed than those of that species (compare fig. 164E), and from other species by subtle differences in the course of the sperm duct and the shape of labium and endites. Females can be distinguished by the shape of the paired epigastric ridges, placed near median region, by the position of the external pockets, just below the level of the anterior apodemes of the anterior receptaculum, the more convex sclerotized margin of the epigastric area, and by the lumen of the anterior receptaculum with two chambers (figs. 169D, 171D, 176D).
MALE (PBI_OON 2309): Total length 1.09.
CEPHALOTHORAX: Labium nearly pentagonal, slightly swollen. Endites convergent, thin (fig. 164E). LEGS: Missing. GENITALIA: Bulb with no apophyses; embolus long; sperm duct slightly coiled (figs. 167D–F, 173F, 174G).
FEMALE (PBI_OON 2304): Total length 1.10.
CEPHALOTHORAX: Labium rectangular.
ABDOMEN: Separated from prosoma, ovoid, dorsum with purple bands. LEGS: Only left leg II present. GENITALIA: Epigastric region with external pockets almost over anterior apodemes (in transparency), epigastric ridges highly convex, near median region; anterior receptaculum with lumen formed by two chambers, anterior apodemes long, directed forward; posterior receptaculum absent, posterior apodeme formed by entire plate (figs. 169D, 171D, 176D).
DISTRIBUTION: Known only from the type locality in Chile (Malleco, map 30).
OTHER MATERIAL EXAMINED: Only one juvenile in the same vial as the holotype.
