Etymology. The specific epithet, to be treated as a Latin adjective, refers to the type locality.

Diagnosis. Differs from other Truncattus species by the wider median septum of the epigynum (Fig. 241), the shape of the vulva (Fig. 242) and the shape of the retrolateral tibial apophysis (Fig. 240).

Description. Male (holotype, UBC-SEM AR00067). Carapace length 1.1 (variation 1.1 – 1.3, n=4); abdomen length 1.1. Chelicera: dark brown to yellow brown. Palp (Fig. 240): light yellow. Retrolateral sperm duct loop very narrow. Retrolateral tibial apophysis short, with tip pointed. Measurements of legs: I 2.1, II 2.0, III 2.2, IV 2.4. Color in alcohol (Fig. 238): carapace dark brown with narrow lateral white margins; abdomen gray brown with light yellow markings in the middle and many white yellow speckles, and with a pair of dark spots in the center; venter sandy yellow with brown patches; legs light yellow to dark brown, although in life the femora are greenish yellow (Figs 234 – 235).

Female (paratype, UBC-SEM AR00068). Carapace length 1.2 (variation 1.1 – 1.3, n=5); abdomen length 1.6. Measurements of legs: I 2.1, II 2.0, III 2.3, IV 2.7. Epigynum (Figs 241 – 242): window small, with opening to copulatory duct at posterior end. Copulatory ducts short, with accessory gland; secondary spermathecae not obvious, primary spermathecae large and spherical. Color in alcohol (Fig. 239): similar to that of male, but first pair of legs lighter in color.

Natural history. Specimens were found on tree trunks in a cloud forest or along its edge.
