Diagnosis : The species is distinguishable from the other species of Euophrys  in Chile, except E. laetata  , by its light, yellow colour and two longitudinal bands of orange hairs on the dorsal abdomen ending in two posterior black spots ( Figs 66–67View FIGURES 66 – 72). The broad wedge shape of the tibial apophysis of the palp and the morphology of the female genitalia, with the fossae touching in the midline, are distinctive ( Figs 68–69View FIGURES 66 – 72). The face and leg markings are also different to those in the other species ( Figs 2View FIGURE 2 H, 3 C). This species can be separated from E. laetata  by the presence of only two black spots on the abdomen, leg colouring and the shape of the epigynum.

Description . Male: Cephalothorax pale, yellow, not darker around lower margin. Surrounds of ALE, PME and PLE, black. Clypeus narrow, pale-yellow. Chelicerae ( Fig. 2View FIGURE 2 H) vertical, yellow with orange markings, with one promarginal tooth and one retromarginal tooth. Endites, labium sternum and ventral abdomen yellow. Dorsal abdomen pale yellow, elliptical with parallel light brown stripes made of hairs leading to a pair of black spots posteriorly ( Fig. 67View FIGURES 66 – 72). Spinnerets yellow. L 1 dark brown with yellow areas patterned as in Fig. 3View FIGURE 3 C. The intensity of the brown varies from specimen to specimen. Femur with three dorsal and two distal dorsolateral spines. Patella with one pair of dorsolateral spines. Tibia and metatarsus with three and four pairs of ventrolateral spines, respectively. Colour patterns of L 2 similar to L 1. L 3 and L 4 have similar markings on the femur but legs plain yellow for the remainder. Similar spination on other legs to L 1. Palp: cymbium dark brown with yellow tibia, tibia with distinctively wedge shaped apophysis ( Fig. 70View FIGURES 66 – 72). Tegulum with strong ventrolateral lobe, large embolus coiled anticlockwise. Dimensions: CL 1.84 ± 0.03 (4), EFL 0.74 ± 0.05 (4), CW 1.21 ± 0.04 (4), AEW 1.17 ± 0.05 (4), AMEW 0.70 ± 0.03 (4), PEW 1.17 ± 0.02 (4), PEW 0.78 ± 0.05 (4), (P 4 +T 4 1.21 ± 0.08 (4).

Female : Same as the male except all legs yellow. Epigynum ( Figs 68–69View FIGURES 66 – 72) sclerotised, with two anterior fossa oriented away from each other and with distinctive, well separated copulatory openings. Fossa guides touching in the midline. Insemination ducts medium length, spermathecae rounded. Dimensions: CL 1.80 ± 0.00, EFL 0.71 ± 0.03 (3), CW 1.28 ± 0.04 (3), AEW 1.14 ± 0.04 (3), AMEW 0.73 ± 0.02 (3), PEW 1.20 ± 0.04 (3), SL 0.78 ± 0.03 (3), ( P 4 + T 4) 1.18 ± 0.06 (3).

Distribution : Known from scattered localities in both the coastal and Andean forests ( Fig. 72View FIGURES 66 – 72).
