Measurements. Males (n=5, min-max): Total length 3.9-4.2, carapace length 1.4- 1.7, width 1.4-1.6, length femur I 3.4-3.8, tibia I 2.7-3.3 mm. Females (n=5, minmax): Total length 4.8-6.1, carapace length 1.6-1.9, width 1.5-1.7, length femur I 2.7-3.0, tibia I 2.2-2.4 mm.

Selected comparative remarks, diagnosis. E. maculipes is well characterised by numerous authors, for details of morphology and distribution see Knoflach and Thaler (2000). Some features are given here for identification and differentiation compared to E. algiricus : Prosoma larger than that of E. algiricus . Sternum dark, with marked light median stripe, which widens anteriorly. Carapace with clear brown median band and reticulate pattern at margins ( Figs 23-24 View Figures 21-27 ). Legs conspicuously speckled. Venter pale. Male palp larger than that of E. algiricus ( Figs 21 View Figures 21-27 vs. 22; see also Kulczyński 1905), in ventral view 0.6-0.7 mm broad, 0.9-1.0 mm long (distance between distal rim of tibia and tip of cymbium). Palpal tibia 1.5 times wider

than long ( Simon 1914). Theridiid tegular apophysis (= TA 2 in Knoflach and Thaler 2000) less prominent than in E. algiricus . Epigynal cavity wider than long, not overlapping receptacula ( Figs 14, 18 View Figures 13-18 ), with narrow median septum. Cavity 0.25-0.31 mm wide. Posterior margin of cavity less distinct than in E. algiricus . Receptacula seminis comparatively large and spherical.

Distribution. This widespread expansive Mediterranean species (for details see Knoflach and Thaler 2000) has recently been reported from Crimea, which is the easternmost record ( Kovblyuk et al. 2008).
