Euophrys saitiformis Simon, 1901

Figs 96–102

Remarks. The synonomy of E. cruziana with E. saitiformis , proposed by Berland (1924) and Galiano (1963), is supported, see comparative anatomy of the types ( Figs 96–102 ). The apparent description of the male of E. saitiformis by Braul et al. (1997) on material from Brazil does not match the abdominal colour pattern of the types of either E. saitiformis or E. cruziana and is considered here to be of E. flordellago n. sp. (see that species).

Type material: E. saitiformis , 1♀, Molle , Chile, 70.97°W, 29.97°S, ( MNHN 20249 , holotype?). E. cruziana , 1♀ ( MNHN 14256 , holotype?) .

Diagnosis. Females of the species are distinguishable from the other species of Euophrys in Chile, except E. flordellago n. sp., by the external morphology of the epigynum. The spermatheca is larger than the fossa and lies immediately below it. It is distinguishable from E. flordellago n. sp. by the internal anatomy of the insemination duct which is coiled, unlike that of E. flordellago n. sp. ( Figs. 58–59 ). The animals also have yellow rather than black chelae and plain yellow rather than the patterned legs seen in E. flordellago n. sp. ( Fig.3 ).

Description: Male: unknown (for the male described in Braul et al. 1997, see E. flordellago n. sp.).

Female: Cephalothorax light brown, grading to yellow around the fovea, black areas surrounding ALE and PLE, scattered white hairs. Pars thoracica brown with darker radiating stripes. Chelicera yellow, straight with two promarginal and one retromarginal teeth. Endites, labium, sternum yellow. Dorsal abdomen beige with mid-brown markings patterned as in Fig. 96 , covered with fine fair silky hair. Ventral abdomen yellow with scattering of faint spots. Spinnerets yellow. Spination: L1 Femur with one dorsal spine, one pair of ventrolateral spines on the tibia, two pairs on the metatarsus; L2 Femur with three dorsal and two distal dorsolateral spines, three pairs of ventrolateral spines on the tibia, two pairs plus a distal ring of spines on the metatarsus; L3 Femur with three dorsal and two distal dorsolateral spines, two pairs of ventrolateral spines on the tibia, two pairs plus a distal ring of spines on the metatarsus; L4 Femur with three dorsal and two distal dorsolateral spines, two pairs of ventrolateral spines on the tibia, three pairs plus a distal ring of spines on the metatarsus. Epigynum: poorly sclerotised, with fossa distinct and widely separated. Insemination ducts short with spiral section close to spermatheca. Spermathecae as large as, and posterior to, the fossae, which are pear-shaped ( Fig. 98 ). Dimensions: CL 1.86, EFL 0.81, CW 1.36, AEW 1.24, AMEW 0.80, PEW 1.24, AL 2. 35, SL 0.87, L 1 3.32, L 2 2. 99, L 3 3. 50, L 1 2.68 (0.82+ 0.39+ 0.55+ 0.51+ 0.41), L 2 2. 96 (1.06+0.53+0.53+0.53+0.31), L3 2.47 (1.23+0.55+0.55+0.75+0.39), L4 4.20 (1.28+0.55+0.87+0.99+0.51).

Distribution. Known from only two localities in Chile and Argentina ( Fig. 102 ).

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.
