Diagnosis. Females of E. rubripes  are similar to those of E. heterogaster  in their stout and vertically oriented MS and in the projections above the ALE. However, they can be recognized by their “mask” pattern, which is composed of a pair of vertical dark lines on the AME and a pair of diagonal ones going from ALE to the lateral margin of the clypeus, merging to form an entire dark clypeal margin ( Fig. 16CView FIGURE 16). They can also be distinguished from other species of the genus by their median posterior opisthosomal projection, which is much thicker and longer than the four lateral projections ( Fig. 16CView FIGURE 16). The males present vertical projections above the ALE as in E. heterogaster  , however, their opisthosoma has only three projections and the same color pattern as in the males of E. taczanowskii  and E. trituberculatus  (see Silva-Moreira & Machado 2016: figs 9A –E). Their unique palp is characterized by the embolous emerging form tegulum at nine o’clock position and by RTA short and wide and DTA pointing to the apex of the cymbium (see Silva-Moreira & Machado 2016: figs 10A –E, 15I).
