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. 2View 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).

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. 1View FIGURES 1 – 3). Spermathecae tubular at base and elongated dorsally, kidney shaped in anterior view; inconspicuous copulatory ducts and sinuous fertilization ducts ( Figs 2–3View 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 4–5View 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).
