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. 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.
