Etymology. The specific epithet refers to the country where the species was found.

Diagnosis. The male can be distinguished from other Belliena species ( Galiano 1963) by the short embolus and the narrower embolic spiral ( Fig. 9 ). The female differs from that of B. biocellosa Simon (see Galiano 1963) in the smaller window and the wider median septum of the epigynum ( Fig. 12 ).

Description. Male (holotype, UBC-SEM AR00135). Carapace length 1.0 (variation 0.9–1.2, n=3); abdomen length 0.9. Chelicera: gray brown; with two promarginal teeth and one retromarginal tooth. Palp ( Figs 9–10 ): gray brown, with white hairs on dorsal femur. Embolus short and slightly curved; retrolateral sperm duct loop about half as wide as palpal bulb, tegular lobe large; retrolateral tibial apophysis long, tibial ventral bump small. First pair of legs with three pairs of ventral macrosetae on tibia and two pairs on metatarsus. Measurements of legs: I 1.8, II 1.7, III 2.1, IV 2.2. Color in alcohol ( Fig. 7 ): carapace gray brown; dorsal abdomen sandy yellow with dark brown markings, anterior and median part with a relatively hard area; legs light yellow. Some male specimens with a small prespiracular bump on the venter of abdomen.

Female (paratype, UBC-SEM AR00136). Carapace length 1.0 (variation 1.0–1.1, n=4); abdomen length 1.6. Chelicera ( Fig. 11 ): with two promarginal teeth and one retromarginal tooth. First tibia with three pairs of ventral macrosetae; first metatarsus with two pairs. Measurements of legs: I 1.8, II 1.7, III 2.0, IV 2.3. Epigynum ( Fig. 12 ): window relatively small, with wide median septum, opening to copulatory duct at posterior end of window. Vulva ( Fig. 13 ): copulatory duct swollen at beginning; spermatheca almost spherical. Color in alcohol ( Fig. 8 ): carapace sandy yellow; abdomen brownish with light yellow speckles and markings.

Natural history. Specimens were found by beating foliage and suspended litter in forest.
