Remarks . Examination of the type of E. rapida  shows that it is indistinguishable from the paratypes and description of the holotype of E. pehuenche  in Galiano (1968) in the relevant details of the genitalia and colour patterns (see comparative drawings in Figs 80–88View FIGURES 80 – 88). There is some variation in the position of the insemination ducts as they may pass partially under or over the spermathecae.

Diagnosis . The species is distinguishable from the other species of Euophrys  in Chile by colour pattern. The palps are black or dark brown, separating this species from all but E. mapuche  and E. tehuelche  . The femur and tibia of the male palp of E. rapida  are dark brown/black, unlike the other two species which are only lightly coloured. The legs in the male are dark coloured with yellow areas and a narrow black longitudinal band along the dorsal surface of the femurs and the tibia of L 1 ( Fig. 3View FIGURE 3 A) not found in other species of the genus. It lacks the well developed white clypeal fringe present in E. rusticana  . The long, narrow shape of the tibial apophysis of the palp is also distinctive. The females are light yellow with brown markings on the abdomen and the morphology of the female genitalia is distinctive, separating this species from all but E. rusticana  ( Figs 89–95View FIGURES 89 – 95). The guides around the fossae are only very lightly sclerotised, and the spermatheca does not extend posterior to the fossa unlike E. rusticana  . The face and leg markings are also different in the different species ( Figs 2View FIGURE 2 G, 3 A).

Description : Male: Cephalothorax dark brown to black with lighter section around and rearwards from the fovea ( Fig. 81View FIGURES 80 – 88). Surrounds of ALE, PME and PLE, and sides of cephalothorax, black. Scattered and variable pattern of white pennate hairs over the cephalothorax. Clypeus narrow, yellow, clypeal fringe not well developed. Chelicerae vertical, brown grading to yellow, with two promarginal teeth and one retromarginal tooth. Endites, labium and sternum brown. Ventral abdomen black with white spots. Abdomen elliptical, with underlying fawn colour and a distinctive pattern of strong black markings ( Fig. 81View FIGURES 80 – 88). Spinnerets yellow. Legs dark coloured with yellow areas and a narrow black longitudinal band down the dorsal surface of the femura, and the tibia of L 1 not found in other species of the genus in Chile ( Fig. 3View FIGURE 3 A). Femur with three dorsal and three distal dorsolateral spines. Patella of L 1 without spines, L 2–4 with a lateral spine. L 1 and L 2 tibias with three pairs of ventrolateral spines, metatarsi with three pairs of ventrolateral spines. L 3 and L 4, tibias with three pairs of ventrolateral spines and two ventral spines, metatarsi with three pairs of ventrolateral spines and one ventral spine. Palp: dark brown to black with lighter areas, tibia with distinctively shaped apophysis ( Figs 86–87View FIGURES 80 – 88). Tegulum with distinct ventrolateral lobe, embolus relatively small, with anticlockwise spiral. Dimensions: CL 1.99 ± 0.07 (6), EFL 0.82 ± 0.05 (6), CW 1.39 ± 0.05 (6), AEW 1.31 ± 0.05 (6), AMEW 0.82 ± 0.03 (6), PEW 1.27 ± 0.03 (6), SL 0.86 ± 0.04 (6), ( P 4 + T 4) 1.41 ± 0.10 (6).

Female : Same as the male except cephalothorax lighter. Epigynum ( Figs 82–85View FIGURES 80 – 88): lightly sclerotised, with two C-shaped fossae mostly lateral to the spermatheca and with distinctive, well separated copulatory openings on the dorsal edge of the fossae. Insemination ducts short/medium length passing anterior to the fossae and ventral to the inner edge of the spermathecae, spermathecae rounded. Dimensions: CL 2.72 ± 0.09 (2), EFL 1.58 ± 0.04 (2), CW 1.95 ± 0.04 (2), AEW 1.58 ± 0.04 (2), AMEW 1.02 ± 0.04 (2), PEW 1.61 ± 0.09 (2), SL 1.24, ( P 4 + T 4) 1.89 ± 0.04 (2).

Distribution . Known from scattered localities in both the coastal and Andean forests ( Fig. 88View FIGURES 80 – 88). Replaced northward from about Temuco by E. rusticana  .
