Diagnosis . The species is distinguishable from the other species of Euophrys  in Chile by its pattern and the generally darker and ‘furry’ appearance of the abdomen ( Figs 89–90View FIGURES 89 – 95), the shape of the tibial apophysis of the male palp and the morphology of the female genitalia ( Figs 91–92View FIGURES 89 – 95). Can be separated from E. rapida  by the tapered shape of the apophysis in the male. In females, there is heavy sclerotisation of the fossa guides and half the spermatheca extends beyond the posterior edge to the fossa. The face and leg markings are also different in the different species ( Figs 2View FIGURE 2 A, 3 B).

Description . Male: Cephalothorax black with a dark orange area around the fovea ( Fig. 90View FIGURES 89 – 95). Surrounds of ALE, PME and PLE also black. Scattered white hairs on the sides with a patch on the posterior midline. Clypeus narrow, yellow with marked white fringe. Chelicerae ( Fig. 2View FIGURE 2 A) vertical, yellow, with two promarginal teeth and one retromarginal tooth. Endites fawn, labium and sternum dark brown. Abdomen fawn, elliptical with a distinctive pattern of black markings covering most of the abdomen ( Fig. 90View FIGURES 89 – 95). Spinnerets yellow with black markings. Ventral abdomen fawn with scattered black spots. L 1 yellow or light brown with dark brown bands ( Fig. 3View FIGURE 3 B). Femur with three dorsal and three distal dorsolateral spines. Tibia and metatarsus with three and two pairs of ventrolateral spines, respectively. L 2, L 3 and L 4 with colours and spine patterns similar to L 1. Palp: mid-brown, tibia with distinctively shaped apophysis ( Figs 93–94View FIGURES 89 – 95). Tegulum with distinct ventrolateral lobe, embolus with slight anticlockwise curve, medium length. Dimensions: CL 2.07 ± 0.06 (6), EFL 0.82 ± 0.03 (6), CW 1.47 ± 0.03 (6), AEW 1.35 ± 0.03 (6), AMEW 0.83 ± 0.03 (6), PEW 1.32 ± 0.04 (6), SL 0.85 ± 0.07 (6), ( P 4 + T 4) 1.43 ± 0.08 (6).

Female : Same as the male except colours lighter, cephalothorax dark brown. Epigynum ( Fig. 89View FIGURES 89 – 95): partially sclerotised with two strongly sclerotised C-shaped lateral fossae oriented anteriorly and with well separated copulatory openings. Insemination ducts medium length not anterior to the fossae, spermathecae rounded, half posterior to the fossae. Dimensions: CL 2.18 ± 0.17 (7), EFL 0.86 ± 0.08 (7), CW 1.57 ± 0.11 (7), AEW 1.38 ± 0.09 (7), AMEW 0.89 ± 0.06 (7), PEW 1.38 ± 0.08 (7), SL 0.89 ± 0.09 (7), ( P 4 + T 4) 1.50 ± 0.13 (7).

Distribution . Widely distributed in both the coastal and Andean forests on Araucaria  and Nothofagus  trees ( Fig. 95View FIGURES 89 – 95). Also found on the Juan Ferdinand Islands ( Berland 1924). Replaced southwards from about Temuco by E. rapida  .
