Type material. Holotype: male, ECUADOR: Napo: Cocodrilo, 0.6490° S, 77.7927° W, elev. 2040 m, 20–24 July 2004, coll. Maddison, Agnarsson, Iturralde, Salazar, WPM#04–054 (UBC-SEM AR00143, QCAZ).

Etymology. The specific epithet refers to the type locality.

Diagnosis. Similar to Ecuadattus elongatus in color pattern and markings, but differs in the shorter tibia of the male palp, the presence of an obvious embolic disc, and the wider palpal bulb ( Figs 36–37 ). This species can be distinguished from E. typicus and E. pichincha in the indistinctive proximal tegular lobe of the male palp ( Fig. 36 ). The palpal bulb of this species is wider than that of E. typicus ( Fig. 36 ). The retrolateral sperm duct loop of this species is narrower than that of E. pichincha ( Fig. 36 ).

Description. Male (holotype, UBC-SEM AR00143). Carapace length 2.9; abdomen length 3.2. Chelicera ( Fig. 35 ): red brown; back surface with a depression; promargin with one bicuspid tooth and retromargin with one tooth. Palp ( Figs 36–37 ): red brown to yellow brown. Embolic disc small; embolus slightly curved; retrolateral tibial apophysis long and finger-like; palpal tibia with a ventral ridge. Measurements of legs: I 7.2, II 5.4, III 6.0, IV 6.3. Color in alcohol ( Fig. 34 ): carapace brown, eye area with guanine deposit, posterior eye area with a narrow yellowish stripe; abdomen brownish, with a longitudinal pale yellow stripe; first leg brown, other legs pale yellow.

Female. Unknown.

Natural history. The holotype was found beating vegetation in cloud forest.
