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
). Legs conspicuously speckled. Venter pale. Male palp larger than that of
E. algiricus
(
Figs 21
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
), 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
).
