Diagnosis. The species is distinguishable from the other species of Euophrys in Chile by its abdominal colour pattern (Figs 103–104) 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 105–106). The face and leg markings are also different from those in the other species (Figs 2 F, 3G).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. 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. 104). 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. 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. 104). Spinnerets yellow. Ventral abdomen yellow with black spots. L1 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 L2, L3 and L4 plain yellow. Similar spination on other legs to L1. Palp: dark brown, tibia with long thin apophysis (Figs 107–108). 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), (P4+T4) 1.15±0.14.
Female: Same as the male except cephalothorax lighter brown and without dorsal stripes. Epigynum (Figs 105–106): 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), (P4+T4) 1.51±0.07 (3).
Biology and distribution. The species is distributed widely in Chile (Fig. 109) and was found on Araucaria and Nothofagus trees
