Males of this species can be distinguished from those of H. guaquiensis by the well-developed lateral apophysis of the conductor ( Fig. 2 e). Females differ by the more elongated and squared median septum, not rounded as in H. guaquiensis , and in the triangular head of spermatheca, which is rounded in H. guaquiensis ( Fig. 4 , 18 c and figs 7–9 in Alvares and Brescovit 2007 ). Description . Male ( holotype ). Colour in ethanol ( Fig. 1 ): carapace brown with dark radial pattern, light brown median band narrowing posteriorly, pale submarginal bands enhanced by white setae. Chelicerae, endites and labium, dark brown. Sternum, and coxae, reddish-brown. Femora and patellae light brown with dark spots. Tibiae and metatarsi reddish brown, with light spots. Scopulae dense, on legs I and II from ventral distal sides of tibiae through tarsi, on legs III and IV from metatarsi. Abdomen brown, with two lines of white setae in posterior half, connected by five dark stripes; venter light brown. FIGURE 1. Hippasella alhue sp. nov .

Variation . Female (male) range, mean ± SD. TL 7.80 – 11.53, 9.92 ± 1.40; CL 4.13 – 5.47, 4.20 ± 0.45; CW 2.87 – 4.00, 2.63 ± 0.38; TCR0.94– 1.11, 1.04 ± 0.06; n = 7 (TL 7.20 – 10.13, 7.59 ± 0.78; CL 3.53 – 5.33, 4.39 ± 0.52; CW 2.87 – 3.80, 3.23 ± 0.28; TCR1.07 – 1.37, 1.07 ± 0.09; n = 9). Etymology . The specific name is a noun in apposition that means soul, ghost or spectre of the dead in the Mapuche language. Biology . Most of the material was collected by Victoria Werenkraut using pitfall traps in two different habitats: In lenga forest ( Nothofagus pumilo ) between 1100 and 1700 m altitude, and in Andean steppe at 1700 m . The presence of males and females in pitfall samples suggest that this is a wandering species Distribution . South-western Argentina (Neuquén and Río Negro) ( Fig. 20 ).
