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) and oval and not projected in the other two species (see Capocasale 1990: fig. 5 and Chamberlin, 1916, pl. 24, fig. 1, respectively).

Copulatory opening located posteriorly, anterior to lateral projections (Fig. 1). Spermathecae tubular at base and elongated dorsally, kidney shaped in anterior view; inconspicuous copulatory ducts and sinuous fertilization ducts (Figs 2–3). 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). 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). Acknowledgments We are grateful to M.
