Diagnosis. The species is distinguishable from the other species of Euophrys in Chile by its abdominal colour pattern ( Figs 73–74 ), and the morphology of the female genitalia ( Fig. 75–76 ). The face and leg markings are also different from those in other species ( Figs 2 D, 3F).The most similar species is E. tehuelche from which it can be distinguished by the fossa guides being O rather than C shaped, the spermatheca larger than the fossa and the insemination ducts passing anterior to the fossa. In the males the palps are yellow rather than brown and there are no stripes of white pennate hairs on the cephalothorax ( Fig. 2 D).

Description: Male: Cephalothorax yellow with brown markings ( Fig. 74 ). Surrounds of ALE, PME and PLE, black. White pennate hairs on the sides below PLE. Clypeus narrow, yellow. Chelicerae ( Fig. 2 D) vertical, yellow, with two promarginal teeth and one retromarginal tooth. Endites, labium and sternum yellow. Abdomen fawn, elliptical with a distinctive pattern of black markings ( Fig. 74 ). Spinnerets yellow. Ventral abdomen yellow with black spots. L1 yellow with dark brown bands ( Fig. 3 F). Femur with three dorsal and one distal dorsolateral spines.. Tibia and metatarsus with three and two pairs of ventrolateral spines, respectively. L2, L3 and L4 with colour patterns similar to L1, femurs with three dorsal and three distal dorsolateral spines on L2, L3 and L4, tibias and metatarsi with three and two pairs of ventrolateral spines, respectively. Palp: yellow, tibiae with distinctively shaped apophysis ( Figs 77–78 ). Tegulum with distinct ventrolateral lobe, embolus moderate size, coiled anticlockwise. Dimensions: CL 1.99±0.09 (7), EFL 0.82± 0.06 (7), CW 1.37±0.02 (7), AEW 1.30±0.04 (7), 0.98, AMEW 0.80±0.05 (7), PLE 1.27±0.05 (11), SL 0.84± 0.08 (11), (P4+T4) 1.42±0.05 (7).

Female: Same as the male except cephalothorax lighter brown and without dorsal stripes. Epigynum ( Figs 75–76 ): sclerotised, with two O-shaped lateral fossae and with distinctive, well separated copulatory openings. Insemination ducts of short/medium length passing anterior to the fossae, spermathecae rounded, larger than the fossae. Dimensions: CL 2.18±0.09 (11), EFL 0.88± 0.03 (11), CW 1.55±0.06 (11), AEW 1.40±0.07 (11), AMEW 0.88±0.05 (11), PEW 1.39±0.06 (11), SL 0.97±0.03, (P4+T4) 1.57± 0.02 (11).

Distribution: Known from scattered localities in both the coastal and Andean forests ( Fig. 79 ).

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.

FIGURE 3. Semi-diagrammatic colour patterns of the first and fourth legs of males in the genus Euophrys. Light stippled areas are orange / mid-brown in colour, plain areas yellow, dark stipples areas are black or very dark brown. In each species there is some variation in the intensity of the colouring.
