Type material. VENEZUELA : Holotype male, MZSP 28436 , La Azulita , Mérida ; Paratypes : 1 female , MZSP 28442 ; 1 male , MZSP , same data as holotype, examined . Additional material examined. COLOMBIA : Norte de Santander : Bochalema, 1 male , MZSP 28433 ; La Donjuana , 1 female , MZSP 28437 . Diagnosis. Males of E. norae can be distinguished from those of their congeners by the shape of palpal bulb which has a distinct embolus tip with a small keel on the dorsal face. The retrolateral spines on the palpal tibia are arranged in two non-aligned rows (in its proximal area) and without an evident gap. Females are recognized by the flat shape of spermathecae receptacles ( Guadanucci & Weinmann 2014: fig. 2 ). Distribution and natural history. Colombia , Norte de Santander : Bochalema and La Donjuana ( Fig. 36 ). Venezuela : Mérida , La Azulita; Táchira , San Juan de Colón. The species occurs north of the Eastern Cordillera between the border between Colombia and Venezuela , at an altitude about 1000 masl . This tarantula inhabits relatively humid environments with an annual mean temperature about 24 °C.
