Diagnosis . The species is distinguishable from the other species of Euophrys  in Chile by its abdominal colour pattern ( Figs 103–104View FIGURES 103 – 109) the shape of the tibial apophysis of the palp, which is longer and thinner than in the other species, and the morphology of the female genitalia ( Figs 105–106View FIGURES 103 – 109). The face and leg markings are also different from those in the other species ( Figs 2View FIGURE 2 F, 3 G).The chelicera are black or dark brown. The most similar species is E. patagonica  from which it can be distinguished by the white stripes of pennate hairs on the cephalothorax ( Fig. 2View FIGURE 2 F). The fossa guides are C rather than O shaped and the insemination ducts are not anterior to the fossae. In the males, the palps are brown/black rather than yellow and the embolus is relatively longer.

Description . Male: Cephalothorax yellow with brown markings ( Fig. 104View FIGURES 103 – 109). Surrounds of ALE, PME and PLE, black. Three white dorsal stripes along pars cephalica made up of white pennate hairs. White hairs also on the sides below PLE and ALE. Clypeus narrow, black. Chelicerae ( Fig. 2View FIGURE 2 F) vertical, black, with two promarginal teeth and one retromarginal tooth. Endites and labium yellow with black stippling. Sternum yellow. Abdomen fawn, elliptical with distinctive pattern of black markings ( Fig. 104View FIGURES 103 – 109). Spinnerets yellow. Ventral abdomen yellow with black spots. L 1 yellow with brown metatarsus. Femur with three dorsal and one distal dorsolateral spines. Patella with one pair of dorsolateral spines. Tibia and metatarsus with three and two pairs of ventrolateral spines, respectively. Colour patterns of L 2, L 3 and L 4 plain yellow. Similar spination on other legs to L 1. Palp: dark brown, tibia with long thin apophysis ( Figs 107–108View FIGURES 103 – 109). Tegulum with small ventrolateral lobe, embolus medium length, coiled anticlockwise. Dimensions: CL 2.15 ± 0.12 (6), EFL 0.88 ± 0.07 (6), CW 1.44 ± 0.08, AEW 1.38 ± 0.11 (6), AMEW 0.84 ± 0.06 (6), PEW 1.36 ± 0.09 (6), SL 0.90 ± 0.06 (6), ( P 4 + T 4) 1.15 ± 0.14.

Female : Same as the male except cephalothorax lighter brown and without dorsal stripes. Epigynum ( Figs 105–106View FIGURES 103 – 109): sclerotised, with two C-shaped anterior fossa oriented towards each other and with distinctive, well separated copulatory openings. Insemination ducts short/medium length not passing anterior to the fossae, spermathecae rounded, smaller than the fossae and do not extend beyond the posterior edge of the fossa. Dimensions: CL 2.00± 0.07 (3), EFL 0.78 ± 0.04 (3), CW 1.37 ± 0.05 (3), AEW 1.30 ± 0.06 (3), AMEW 0.83 ± 0.07, PEW 1.30 ± 0.06 (3), SL 0.85 ± 0.04 (3), ( P 4 + T 4) 1.51 ± 0.07 (3).

Biology and distribution. The species is distributed widely in Chile ( Fig. 109View FIGURES 103 – 109) and was found on Araucaria  and Nothofagus  trees
