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. 15C ), while in females of E. pustulosus these structures are yellow ( Fig. 15E ). 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.
