Remarks. Interpretation of color pattern, epigyne and its internal structure of this species in comparison with females of Eu. gambosa and Eu. pseudogambosa from Jerusalem does not give unequivocal conclusion on relationships, but does not permit to consider it conspecific with either of the two. The solution of the problem requires more research and, first of all, finding of males which are more differenciated.

Female

Cephalothorax brownish grey, median thoracal streak greyish yellow; eye field blackish brown with sparse, tiny, white hairs, well visible but not striking, concentrating along anterior and lateral edges of eye field; sides yellowish grey, getting gradually lighter, lower parts light yellow, ventral edge light with indistinct thin brownish line. Abdomen: median line of dark spots consists anteriorly and posteriorly of traces of fused triangular components, with separate three central triangles, connected by their apexes; laterally followed by irregular narrow white and then broad dark stripes; another thin white streak, separates these from dark sides (Figs. 235, 244). Frontal aspect: eyes I located on a narrow, dark brown pigmented stripe, surrounded by inconspicuous setae, colorless, whitish tipped; clypeus divided into lower light yellow belt with dense white setae, and upper bald stripe just beneath eyes AME. Pedipalps uniformly whitish with sparse long blackish setae on tarsus. Ventral aspect: sternum whitish yellow with light grey margin and short dark hairs; coxae whitish with yellow shade; abdomen whitish with two blackish parallel linear spots in posterior half, widely spaced, a darker spot in front of spinnerets, dark waving lines of sides of abdomen extend on margins of ventral surface. Legs: yellow with femora I-IV whitish; blackish spines; three pairs of ventral spines on tibia I. Epigyne: resembling closely Eu. pseudogambosa and gambosa; thin sclerotized ridge arises from the posterior edge of the white window, bending first towards the mid-line of epigyne and at the mid-length of the window bends laterally and runs transversely in the opposite direction (Figs. 245) reaching sclerotized small plate in the middle of window, but from the direction opposite to Eu. pseudogambosa and differently than in Eu. gambosa. Sclerotized copulatory opening at the end of transverse part of heavily sclerotized channel directed medially, after sharp bent the channel makes one and half tight loop, then gently bent long channel, somewhat thinner than in Eu. pseudogambosa joins transverse oval spermatheca (Figs. 246); both spermatheca and channel are located within limits of membraneous window.
