Diagnosis. The species is distinguishable from the other species of Euophrys in Chile by the shape of the tibial apophysis of the palp in the male, which has a shelf and sharp point ( Figs 53–54 ). In the females, the morphology of the female genitalia ( Figs 51–52 ) can be distinguished by the combination of the fossa are widely separated and orientated laterally, the seminal ducts do not pass anteriorly to the fossae, the spermathecae are relatively small and only partly posterior to the fossa. The face and leg markings are also different from those of the other Euophrys species ( Figs 2 C, 3D).

Description. Male: Cephalothorax; brown, PLE and ALE surroundings black, pars thoracica with lighter median strip and a scattering of white pennate hairs on the sides, not darker around lower margin. Clypeus narrow, yellow to light brown. Chelicerae vertical, yellow with light brown proximal areas ( Fig. 2 C), with two promarginal teeth and one retromarginal tooth. Endites, labium, sternum and ventral abdomen yellow with light brown margins. Abdomen pale yellow, elliptical, with a regular pattern of dark brown markings ( Fig. 50 ). Spinnerets yellow. All legs yellow with a distinctive pattern of brown to black bands ( Fig. 3 D). Spination [shows some variation compared to the pattern reported by Galiano (1962b)], L1, femur with three dorsal and one or two distal dorsolateral spines, tibia and metatarsus each with two or three and two pairs of ventrolateral spines respectively. Similar spination on other legs to L1 except L4 (sometimes L3) has one spine on the patella, L2–4 tibia has three pairs of ventrolateral spines. Palp: Tegulum ( Figs 53–54 ) trapezoidal with small proximal retrolateral lobe, embolus very small, curved. Tibial apophysis with a distinct shelf. Dimensions: CL 1.76±0.20 (8), EFL 0.71±0.05 (8), CW 1.18±0.11 (8), AEW 1.18±0.06 (8), AMEW 0.73±0.06 (8), PEW 1.14±0.07 (8), SL 0.77±0.09 (8), (P4+T4) 1.21±0.15 (8).

Female: Cephalothorax; brown, PLE and ALE surroundings black, pars thoracica with lighter median strip and a scattering of white pennate hairs on the sides, not darker around lower margin. Clypeus narrow, yellow to light brown. Chelicerae vertical, yellow with light brown proximal areas with two promarginal teeth and one retromarginal tooth. Endites, labium, sternum and ventral abdomen yellow with light brown margins. Abdomen pale yellow, elliptical, with a regular pattern of dark brown markings ( Fig. 49 ). Spinnerets yellow. All legs yellow with a distinctive pattern of brown to black bands ( Fig. 3 D). Spination (shows some variation compared to the pattern reported by Galiano 1962b), L1, femur with three dorsal and one or two distal dorsolateral spines, tibia and metatarsus each with two or three and two pairs of ventrolateral spines respectively. Similar spination on other legs to L1, except L4 (sometimes L3) has one spine on the patella, L2–4 tibia has three pairs of ventrolateral spines. Epigynum ( Figs 51–52 ): poorly sclerotised, with two widely separated fossae oriented outwards and with distinctive, well separated copulatory openings. Insemination ducts relatively short and direct, spermathecae round, with pointed fertilization duct on anterior edge, smaller than the fossae. Dimensions: CL 1.89±0.21 (13), EFL 0.79±0.07 (13), CW 1.36±0.13 (13), AEW 1.27±0.11 (13), AMEW 0.79±0.07 (13), PEW 1.28±0.09 (13), SL 0.86±0.10 (13), (P4+T4) 1.39±0.15 (13).

Distribution. Known from widely scattered localities in Chile and Argentina ( Fig. 55 ).

Figures

FIGURE 2. Male face patterns (semidiagramatic) in the genus Euophrys. Stippled areas are orange / mid-brown in colour, plain areas yellow, black areas are black or very dark brown. White or light grey pennate hairs are found in different patterns in different species. In each species there is some significant variation in the intensity of the colouring. Pattern unknown for E. saitiformis.
