Type material: 1 ♀, Coquimbo , Chile, 71.35 °W, 29.95 °S ( MNHN 22401, holotype?)GoogleMaps  .

Diagnosis . The species is distinguishable from the other species of Euophrys  in Chile, except E. mapuche  , by its light yellow colour and two faint bands of orange hairs on the dorsal abdomen ( Fig. 63View FIGURES 63 – 65). It is distinguishable from E. mapuche  by its plain yellow legs ( Fig. 3View FIGURE 3 E) and the pattern of dark markings on the posterior end of the dorsal abdomen (compare Figs 63View FIGURES 63 – 65 and 66View FIGURES 66 – 72). The morphology of the female genitalia can be distinguished by the combination ( Fig. 64–65View FIGURES 63 – 65) of the fossae being widely separated, the insemination ducts short and direct and passing anteriorly to the fossa and the spermatheca are similar size to the fossae.

Description : Male: Unknown. If it follows the pattern of the other species in this genus in Chile, the male will be similar in colouring to the female. Hence it will be distinguishable by the fact that the legs are of plain yellow colour.

Female : Cephalothorax; pars cephalica orange, PLE surroundings black, pars thoracica pale yellow, with pale orange markings, not darker around lower margin. Clypeus narrow, pale-yellow. Chelicerae vertical, yellow, with two promarginal teeth and one retromarginal tooth. Endites, labium, sternum and ventral abdomen yellow. Abdomen pale yellow, elliptical with pair of parallel light brown bands leading to black patterning posteriorly ( Fig. 63View FIGURES 63 – 65). Spinnerets yellow. All legs yellow. L 1, femur with three dorsal and two distal dorsolateral spines. Patella with a single distal and one proximal pair of dorsolateral spines. Tibia and metatarsus with three and two pairs of ventrolateral spines, respectively. Similar spination on other legs to L 1, except all have three distal spines rather than two on the femur, two pair of dorsolateral spines on the patella and L 3 tibia has four pairs of ventrolateral spines. Epigynum ( Figs 64–65View FIGURES 63 – 65): poorly sclerotised, with two well separated lateral fossae oriented anteriorly and with distinctive, well separated copulatory openings. Insemination ducts relatively short and direct, passing anteriorly to the fossa, spermathecae same size as the fossae, pear-shaped, with pointed fertilization duct on dorsal anterior edge. Dimensions: CL 2.29, EFL 0.93, CW 1.55, AEW 1.49, AMEW 0.93, PEW 1.42, SL 0.93, L 1 3.54 (1.18 + 0.68 + 0.68 + 0.50 + 0.50), L 2 3.66 (1.18 + 0.68 + 0.68 + 0.62 + 0.50), L 3 4.77 (1.49 + 0.68 + 0.93 + 0.80 + 0.87), L 4 4.83 (1.49 + 0.68 + 0.93 + 1.11 + 0.62).
