Type material. Holotype: male, ECUADOR: Pichincha : Bellavista, Cloud Forest Reserve, 0.012–016° S, 78.682° W, elev. 2050–2240 m, 9–10 November 2010, coll. W. Maddison, D. Maddison, M. Vega & M. Reyes, WPM#10–065 (UBC-SEM AR00144, QCAZ). Paratypes: 1 female, same data as holotype (UBC-SEM AR00145); 4 males and 1 female in two vials, same data as holotype.

Etymology. A noun in apposition taken from the type locality.

Diagnosis. Resembles Ecuadattus typicus in coloration and markings ( Figs 38–39 ), but differs from it by the wider palpal bulb, the shorter male palpal tibia, the presence of a ventral ridge on the palpal tibia ( Figs 40–41 ), and the wider median septum of the epigynum ( Fig. 43 ). Also see the diagnosis of E. napoensis .

Description. Male (holotype, UBC-SEM AR00144). Carapace length 2.3 (variation 1.9–2.3, n=5); abdomen length 2.3. Chelicera ( Fig. 42 ): dark red brown; promargin with one bicuspid tooth and retromargin with one tooth. Palp ( Figs 40–41 ): yellow brown. Bulb wide; tegular lobe present; embolic disc obvious; embolus slightly curved; retrolateral tibial apophysis long and finger-like; palpal tibia with a ventral ridge. Measurements of legs: I 4.8, II 4.0, III 4.2, IV 4.9. Color in alcohol ( Fig. 38 ): carapace dark brown, eye area with guanine deposit, behind eye area and lateral margins with yellowish stripes; abdomen brownish, with numerous light yellow speckles and a longitudinal wide stripe; first leg dark brown, other legs pale yellow with brownish annuli.

Female (paratype, UBC-SEM AR00145). Carapace length 2.2; abdomen length 3.5. Chelicera: with two promarginal teeth and one retromarginal tooth. Measurements of legs: I 3.8, II 3.6, III 4.3, IV 4.9. Epigynum ( Fig. 43 ): median septum present and wide, with opening to the copulatory duct anteriorly. Vulva ( Fig. 44 ): copulatory duct relatively long but not coiled; spermatheca oval. Color in alcohol ( Fig. 39 ): similar to that of male, but first leg paler in color and dorsum of abdomen obviously with a pair of white spots near posterior end.

Natural history. Specimens were found beating foliage and on mossy tree trunks in cloud forest.
