Diagnosis. Females of E. pustulosus are very similar to those of E. caudatus in their cryptic bark-dweller habitus with rugose tegument and predominant dark-brown coloration. Both species also share squared leg segments and protuberant anterior femora suffused with many conical tubercles. However, E. pustulosus can be distinguished by the yellow blister-shaped sockets on the ventral surface of femora I and II and by the anterior projection on the epigynal plate, which covers the copulatory openings entirely. Males can be easily recognized by their equal-sized, short and spiniform opisthosomal projections, by a basal indentation on the DTA and by its curvature (pointing to the dorsum of the cymbium).
Description. See Machado et al. (2015).
Distribution. BRAZIL: São Paulo, Espiírito Santo, Bahia; ECUADOR: Cotopaxi; PANAMA: Panama City, Colón (Fig. 17A).
Variation. Most of the specimens examined by Machado et al. (2015) present a predominantly brown coloration. Here, we present two additional color variations for the females of E. pustulosus: dorsum of prosoma and opisthosoma black with front and legs yellow (Figs 14A, B) and brown with distal portion of femora I and dorsum of opisthosoma yellow (Figs 14C, D).
