Diagnosis. Females of E. tigrinus sp. nov. resemble those of E. pulcher in their body coloration pattern (yellowish / orange suffused with black stripes and stains), and those of E. rubripes in the stout and long median posterior opisthosomal projection. However, they can be recognized by a large rectangular guanine stain on the thoracic region, straight anterior border of the opisthosoma and by the absence of lower lateral opisthosomal projections (Fig. 10 A), while E. rubripes and E. pulcher present two pairs of lateral opisthosomal projections. The epigynum differs in ventral view from those of other species of the genus by the depressed and reduced median field with deeply excavated copulatory openings (Fig. 10 C). Males can be distinguished from those of other species by their opisthosoma with a long and acute median posterior projection, prosoma dark-orange with a bifid median black stain (Fig. 11 A) (differing from other males, which may present just a single dark median line) and by the palp with TF and embolus emerging at twelve o’clock (Fig. 11 C).
Etymology. The specific name is a Latin masculine adjective which refers to the body coloration of both males and females, whose yellow prosoma and legs (dark-orange in males), with black stripes, resembles the pattern of a tiger pelage.
