Diagnosis : This species can be easily separated from the congeners by the shape of the tibial apophyses in the males and the shapes and positions of the fossae in the females ( Galiano 1985). The closest related genus in Chile is Admesturius  and the genera can be distinguished by the flattened body form in Admesturius  compared to the relatively high carapace of Hurius  . Spines are also absent or greatly reduced on the legs of Admesturius  . Hurius  is most easily distinguished by the very distinctive ‘furry’ appearance of the more ventral of the two apophyses in the male ( Figs 111–112View FIGURES 110 – 116). In the females, the shapes of the fossa and gonopore ( Fig. 114View FIGURES 110 – 116) are markedly different to that found in Admesturius  .

Description : Male: Cephalothorax and abdomen of dark brown colour with darker markings notably surrounding ALE, PME and PLE ( Fig. 110View FIGURES 110 – 116). Clypeus medium-sized, fawn with dark brown fringe of hairs. Chelicerae vertical, relatively narrow dark brown grading to fawn, with five promarginal teeth and one retromarginal tooth. Endites and labium yellow-brown. Sternum dark brown. Abdomen patterned as in Fig. 110View FIGURES 110 – 116. Ventral surface of the abdomen and the spinnerets also brown. L 1 a little larger and heavier than the other legs. All legs of even fawn colour. Femur with five dorsal spines, tibia and metatarsus with five and four pairs of ventrolateral spines, respectively. Palp ( Figs 111–112View FIGURES 110 – 116): fawn, tibia with two apophyses, ventral one black, very long with distinctive furry appearance. Tegulum with lateral lobe, embolus long, not coiled, not set in depression. Dimensions (after Galiano 1985): CL 1.73, EFL 0.71, CW 1.17, AEW 1.11, AMEW 0.68, PEW 1.24, CW 1.36, SL 0.74, ( P 4 + T 4) 1.17.

Female ( Figs 113 – 14View FIGURES 110 – 116, after Galiano 1985): General appearance similar to male. Epigynum: with a pair of posterior notches at the posterior edge of the epigynum and a pair of anterior pockets not containing copulatory openings. Openings are lateral to the spermathecae and indistinct. Insemination ducts small and short, spermathecae subdivided into compartments. Dimensions (after Galiano 1987): CL 1.63, EFL 0.68, CW 1.22, AEW 1.03, ALED 0.16, PEW 1.11.

Biology and distribution. The species is only known from three locations in the Chilean Andes and coastal forest ( Fig. 116View FIGURES 110 – 116).
