Diagnosis. Females of E. caudatus  are very similar to those of E. pustulosus  in the cryptic bark-dweller habitus with predominant dark-brown body coloration, squared leg segments and knobby femora, however, they can be distinguished at first sight by the presence of vivid orange/reddish blister-shaped setae sockets on the ventral surface of their anterior femora ( Fig. 15CView FIGURE 15), while in females of E. pustulosus  these structures are yellow ( Fig. 15EView FIGURE 15). Females of E. caudatus  also present a large median septum on the epigynal plate separating the exposed copulatory openings. Males can be recognized by the half-moon shaped stains on the dorsum of the opisthosoma, wide and stout opisthosomal projections and by the DTA pointing upwards.

Description. See Machado et al. (2015).

Distribution. BRAZIL: Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Rio de Janeiro, Bahia and Amazonas; VENEZUELA: Aragua; PUERTO RICO: Mora ( Fig. 17AView FIGURE 17).
