REMARKS: This species so far was recorded in Krymskaya Region, Ukraine on undetermined sedge plant ( Mitrofanov et al . 1983 ). Authors of this species reported that specific features of E. lentiginosus are the absence of lines on prodorsal shield and 5­rayed empodium. However, females found in Poland have 4­rayed empodium and there are three entire lines in the centre of the shield forming by spots. What is more, the lines are more distinct and visible on the shield of nymph and larva. Specimens from Ukraine and Poland differs also in: the number of opisthosomal annuli, the appearance of microtubercles and the shape of the prodorsal shield. In females described by Mitrofanov et al. (1983) there are 88–95 annuli, microtubercles are ellipsoidal with conical top, the anterior margin of prodorsal shield is blunt. Females found in Poland have 54–71 annuli, bead­like microtubercles and short subrounded lobe reaching the half of the chelicerae. All these differences between the populations collected in Ukraine and Poland may result from intraspecific variability influenced by host, seasonal, geographical or others factors.
