Diagnosis . From the published descriptions it is likely that the abdominal pattern is distinct. The marked patterns of white pennate hairs down the centre and sides of the abdomen and the distinctive shape of the dark pattern on the dorsal surface of the abdomen have not been reported in the other Chilean species in the genus.

Description : Male (after Galiano 1979): Cephalothorax dark reddish brown with pars cephalica black. White stripes of pennate hairs along each side. Clypeus narrow, with light brown fringe. Chelicerae midbrown, groove deeply excavated. Promargin with a low blunt tubercle near base of chelicera and two teeth, one in the middle and the other on the angle. Retromargin with a single robust tooth. Endites and labium yellow-brown. Sternum dark brown. Abdomen light brown with dark brown thick median stripe leading to four large lateral branches on each side (see Fig. 32View FIGURES 32 – 38). Distinct broad stripes of white pennate hairs down the centre and sides of the abdomen bordered by golden reflective scales. Ventral surface mid-brown with lines of lighter spots. Spinnerets mid brown. L 1 reddish brown with distal end darker. Tarsus yellow. Other legs light brown with dark brown markings at distal ends of each segment. Tibia and metatarsus with three and two pairs of ventrolateral spines, respectively. Similar spination on leg 2. Other legs pale, spines less distinctive. All legs, especially ventral femora and tibiae, with long white hairs. Spination: L 1, femur with three dorsal and two distal dorsolateral spines, patella no spines, tibia with three pairs of ventrolateral spines, metatarsus with two pairs of ventrolateral spines, L 2 femur with three dorsal and two distal dorsolateral spines, patella no spines, tibia with one right and one pair of ventrolateral spines, metatarsus with two pairs of ventrolateral spines, L 3 femur with three dorsal and three distal dorsolateral spines, patella no spines, tibia with a pair of ventrolateral spines, metatarsus with four ventrolateral spines, L 4 femur with three dorsal and two dorsolateral spines, patella no spines, tibia with one posterior and one pair of ventrolateral spines, metatarsus with 4 ventrolateral spines. Palp ( Figs 35–36View FIGURES 32 – 38): tibia with single small apophysis. Tegulum without lobe. Dimensions: CL 2.60, EFL 1.03, CW 2.17, AEW 1.57, PEW 1.77.

Female : Similar to the male, except L 1 and palp same colour as other legs. Chelicerae with two promarginal and one retromarginal teeth. Spination: L 1, femur with three dorsal and two distal dorsolateral spines, patella no spines, tibia with three pairs of ventrolateral spines, metatarsus with two pairs of ventrolateral spines, L 2 femur with three dorsal and two distal dorsolateral spines, patella no spines, tibia with one right and one pair of ventrolateral spines, metatarsus with one right and one pair of ventrolateral spines, L 3 femur with two dorsal and three distal dorsolateral spines, patella no spines, tibia with one ventrolateral spine, metatarsus with four ventrolateral spines, L 4 femur with three dorsal and one dorsolateral spines, patella no spines, tibia with one posterior and one pair of ventrolateral spines, metatarsus with four ventrolateral spines. Epigynum ( Fig. 37View FIGURES 32 – 38): poorly sclerotised, with a posterior median notch and pocket on the margin of the epigastric fold. Insemination ducts long and convoluted, spermathecae small and round. Dimensions: CL 2.93, EFL 1.13, CW 2.17, AEW 1.65, PEW 1.87.

Distribution . Distributed from Chile to Uruguay and Argentina.
