Diagnosis . Cephalothorax and dorsal abdomen dark brown, latter with white margin on anterior third and a white spot halfway down each side of the abdomen in females ( Fig. 39View FIGURES 39 – 48). Spermatheca touch in the midline with insemination ducts passing ventrally ( Fig. 43View FIGURES 39 – 48).

Description . Male (paratype from Santiago): Cephalothorax dark orange-brown, its lower margin grading to black. Surrounds of ALE, PME and PLE, black. Clypeus narrow, without a fringe. Chelicerae geniculate, tan, with one large and one smaller promarginal teeth and one very large straight retromarginal tooth. Endites dark brown grading to yellow. Labium and sternum brown. Abdomen mid-brown with white edge around the anterior third. Without a white spot half way down each side ( Fig. 40View FIGURES 39 – 48). Spinnerets mid-brown. Ventral abdomen same as dorsal surface of the abdomen. L 1: robust, femur, patella, tibia, tarsus and metatarsus mid-brown. Other legs pale yellow, spines less distinctive. Spines: L 1 femur one dorsal and two distal dorsolateral spines, tibia three pairs of ventrolateral spines, metatarsus two pairs of ventrolateral spines, L 2 femur one dorsal and two distal dorsolateral spines, tibia single ventral spine, metatarsus two pairs of ventrolateral spines, L 3 femur one dorsal and two distal dorsolateral spines, tibia no spines, metatarsus one pair of ventrolateral spines, L 4 femur two dorsal and two distal dorsolateral spines, tibia one ventral spine, tarsus one pair of ventrolateral spines. Palp ( Figs 46–47View FIGURES 39 – 48): tibia with single small apophysis. Tegulum with small distal lobe next to the embolus but without a proximal lobe, embolus small and blunt. Dimensions: CL 1. 6 7, E F L 0. 7 4, C W 1. 3 0, A E W 0. 8 7, A M E W 0. 5 6, P E W 1. 11, A L 1. 9 2, L 1 3. 1 (0.99 + 0.50 + 0.68 + 0.56 + 0.37), L 2 2.22 (0.68 + 0.43 + 0.37 + 0.37 + 0.37), L 3 2.1 (0.68 + 0.31 + 0.37 + 0.43 + 0.31), L 4 2.85 (0.93 + 0.43 + 0.62 + 0.56 + 0.31).

Female (holotype): Cephalothorax dark orange-brown, its lower margin grading to black. Surrounds of ALE, PME and PLE, black ( Fig. 39View FIGURES 39 – 48). Clypeus narrow, with light grey fringe. Chelicerae geniculate, tan, with two promarginal teeth and one medium-sized straight retromarginal tooth. Endites dark brown grading to yellow. Labium and sternum dark brown. Abdomen mid-brown with white edge around the anterior third. White spot half way down each side ( Fig. 39View FIGURES 39 – 48). Spinnerets mid-brown. Ventral abdomen same as dorsal surface of the abdomen. L 1: robust, femur, patella, tibia and tarsus dark brown, metatarsus yellow. Other legs pale yellow, with longitudinal dark markings, spines less distinctive. Spines: L 1 femur one dorsal and two distal dorsolateral spines, tibia three pairs of ventrolateral spines, metatarsus two pairs of ventrolateral spines, L 2 femur one dorsal and two distal dorsolateral spines, tibia two pairs of ventrolateral spines, metatarsus two pairs of ventrolateral spines, L 3 and L 4 femur one dorsal and one distal dorsolateral spines, tibia no spines, metatarsus one pair of ventrolateral spines. Epigynum ( Figs 43–44View FIGURES 39 – 48): sclerotised, with two anterior fossa oriented towards each other and with distinctive, well separated copulatory openings. Insemination ducts medium length passing under the ventral surface of the small spermathecae with a posterior ventral turn.
