Other material examined. CHILE. Arica y Parinacota Region: Parinacota Province: 62 km from Putre, Quebrada de Allane [17°59’S 69°38’W], 3851m, I-VI.2011 A. Taucare Rios col., 1 3 (IBSP 163254); same data, 1 Ƥ (IBSP 163255); same data, 1 Ƥ (MNHN).

Diagnosis. The female of Allocosa yurae is easily distinguished from A. brasiliensis and A. orinus by the shape of the head of the spermathecae, which is elongated in A. yurae ( Fig. 2 View FIGURES 1 – 3 ) and oval and not projected in the other two species (see Capocasale 1990: fig. 5 and Chamberlin, 1916, pl. 24, fig. 1, respectively).

Description. Male: Described by Brescovit & Álvares, 2011: 59. Female (IBSP 163255): Total length 9.3. Carapace length 4.0, width 2.8.

Chelicerae: promargin with two small teeth, retromargin with three teeth, median tooth largest. Epigynum: epigynal plate not elevated, with lateral projections rounded at the bases. Copulatory opening located posteriorly, anterior to lateral projections ( Fig. 1 View FIGURES 1 – 3 ). Spermathecae tubular at base and elongated dorsally, kidney shaped in anterior view; inconspicuous copulatory ducts and sinuous fertilization ducts ( Figs 2–3 View FIGURES 1 – 3 ).

Colouration as in male.

Biology. Allocosa yurae has been found in wetlands in the highlands of northern Chile. These spiders build their nests in holes in damp ground or under rocks near Distichia muscoides Nees & Meyen (Juncaceae) and Oxychloe andina Phil. (Juncaceae) ( Figs 4–5 View FIGURES 4 – 5 ). Specimens have been collected by hand on the ground or with pitfalls traps.

Distribution. South of Peru (Arequipa) and North of Chile (Arica y Parinacota).
