Etymology. The specific epithet, to be treated as a Latin adjective, refers to the country where the species was found.

Diagnosis. Easily distinguished from the other two species by the large window and the narrow median septum of the epigynum (Fig. 251), the shape of the vulva (Fig. 252) and the larger embolic disc (Fig. 249).

Description. Male (holotype, UBC-SEM AR00069). Carapace length 1.4 (variation 1.2 – 1.5, n=22); abdomen length 1.5. Chelicera (Fig. 250): dark yellow brown. Palp (Fig. 249): femur, patella and tibia light yellow, cymbium yellow brown. Embolus relatively longer, retrolateral sperm duct loop very narrow. Retrolateral tibial apophysis long and finger-like; ventral tibial bump small. Measurements of legs: I 2.7, II 2.5, III 2.6, IV 3.0. Color in alcohol (Fig. 247): carapace dark red brown without lateral white margins, posterior part with a medial yellow brown stripe; abdomen brown with a medial light yellow elongated marking and many light yellow speckles; venter light brown, with a wide medial gray brown stripe behind genital groove; legs yellow brown, with indistinct gray brown annuli.

Female (paratype, UBC-SEM AR00070). Carapace length 1.6 (variation 1.2 – 1.6, n=17); abdomen length 2.5. Tibia of first leg with three pairs of ventral macrosetae; first metatarsus with two pairs. Measurements of legs: I 2.7, II 2.5, III 3.1, IV 3.4. Epigynum (Figs 251 – 252): window large, with opening to copulatory duct close to the middle along its outer margin. Secondary spermatheca close to the opening, primary spermatheca small and oval. Color in alcohol (Fig. 248): similar to that of male.

Natural history. Specimens were found on tree trunks.
