    Diagnosis. Seem to differs (if not secondarily changed) from E. patagiata by striking white setae on clypeus under AME; abdomen dark brown dotted yellow with white anterior edge and four thin white chevrons posteriorly.

    Male

    Cephalothorax: yellow (presumably faded) with brown eye field, black encircling of lateral eyes; light belt just behind eye field has waving outline and consists of whitish semicircular spots behind eyes III, connected narrowly in front of fovea, anteriorly stretching to eyes II only; differs from both E. jucunda and E. patagiata by a row of short, thin white setae along anterior edge of eye field, on dorsal parts of rims of eyes I, slightly denser triangular white condensation between eyes AME. Abdomen: dorsum and sides dark brown mottled yellow; very prominent white semilunar spot at the anterior edge of abdomen; four thin white chevrons in the posterior half of the abdomen, much narrower than in Evarcha jucunda; broad white marginal streak along posterior half of abdomen, with a pair of isolated white marginal spots along anterior half. Frontal aspect: striking white setae on clypeus under AME, making white triangle between AME ventrally; on rims of AME setae whitish, on rims of ALE whitish ventraly and medially but dark dorsally and laterally; setae under ALE whitish, sparse and inconspicuous; tegument pigmented dark in the immediate narrow surrounding of eyes I, yellow on clypeus and beneath ALE in an area merging with sides of cephalothorax; edge of clypeus pigmented dark, under AME almost black; chelicerae yellow, basally with triangular frontal bulge. Legs on studied, long preserved specimen, almost uniformly light yellow, without traces of distinct pattern, ventral setae on tibia and patella I whitish; shorter sparse whitish setae ventrally on femur I. Ventral aspect: coxae, mouth parts abd sternum whitish yellow, ventral surface of abdomen whitish with three darker indistinct lines in the posterior part, sides contrasting dark, in E. patagiata the whole ventral surface of abdomen was black. Palpal organ very similar to E. patagiata, from which differs by shorter embolus, arising near the mid length of bulbus, tibial apophysis slightly longer.

    Measurements (mm): Male. Length of cephalothorax 2.05; length of abdomen 1.93.
