Diagnosis. Males of E. amandae differ from those of other species by the uniquely bifid aspect of the palpal bulb embolus which has a small keel and by the short spines on the retrolateral palpal tibia, arranged in two nonaligned rows and the outer row with a distal gap. Females differ from those of other species by having spermathecae composed of two protuberant triangular receptacles, well separated, with two conspicuous longitudinal striae on the dorsal face ( Guadanucci & Weinmann 2014: fig. 3).

Distribution and natural history. E. amandae is known only from Colombia in the Departments of Boyacá (Santa María), Meta (Guamal) and Guaviare (San José de Guaviare, Cerro Azul; new record), between 300–800 masl ( Fig. 36 ).This tarantula inhabits the eastern foothills of the Eastern Cordillera at the transition of the Andes and the eastern savannas and in the transition between the savannas of the Orinoquía and the Amazonian forests. These territories are characterized by their water wealth, with an annual mean temperature about 26 °C and a relatively high humidity.
