Etymology. Latin typicus (typical), indicating that this is the type species of the genus.

Diagnosis. Differs from Ecuadattus napoensis by the long palpal tibia, the distinct tegular lobe and the absence of a ventral ridge on the palpal tibia ( Figs 47–48 ). This species can be distinguished from E. pichincha by the narrower palpal bulb, the longer palpal tibia, the absence of a ventral ridge on the palpal tibia ( Figs 47–48 ), and the narrower median septum of the epigynum ( Fig. 51 ).

Description. Male (holotype, UBC-SEM AR00146). Carapace length 2.5 (variation 1.9–2.8, n=11); abdomen length 2.8. Chelicera ( Fig. 49 ): dark red brown; promargin with one bicuspid tooth and retromargin with one tooth. Palp ( Figs 47–48 ): dark yellow brown. Palpal bulb narrow; tegular lobe distinct; embolic disc obvious; embolus slightly curved; retrolateral tibial apophysis long and finger-like. Measurements of legs: I 6.4, II 4.8, III 5.5, IV 5.9. Color in alcohol ( Fig. 45 ): carapace dark brown, eye area with guanine deposit, behind eye area with a longitudinal yellowish stripe; abdomen brown, with numerous light yellow speckles and a longitudinal stripe; first leg dark brown, other legs pale yellow to brown. Some male specimens with yellowish margins on dorsal abdomen.

Female (paratype, UBC-SEM AR00147). Carapace length 2.0 (variation 2.0–2.3, n=5); abdomen length 2.0. Chelicera ( Fig. 50 ): with two promarginal teeth and one retromarginal tooth. Measurements of legs: I 3.8, II 3.4, III 4.3, IV 4.7. Epigynum ( Fig. 51 ): median septum wide, with opening to the copulatory duct anteriorly. Vulva ( Fig. 52 ): copulatory duct not coiled; spermatheca round. Color in alcohol ( Fig. 46 ): paler than that of male, and markings on dorsal abdomen more obvious, first leg light yellow. Some female specimens as dark in color as that of holotype male.

Natural history. Specimens were found beating vegetation in cloud forest.
