Etymology. The specific epithet refers to the country where the species is found. Diagnosis. Similar in markings on the abdomen to Omoedus microphthalmus (L. Koch) (see Berry et al.

1996), but can be distinguished by the wider spirals of the embolus and the wider bulb of the male palp (Figs

142–143), and the shape of the epigynum ( Fig. 145).

Description. Male (holotype, UBC-SEM AR00129). Carapace length 1.9 (variation 1.8–2.0, n=4); abdomen length 1.8. Chelicera ( Fig. 144): dark brown; with two promarginal teeth and one retromarginal tooth. Palp ( Figs 142–143): cymbium yellow brown, other segments cream. Retrolateral sperm duct loop about two thirds of bulb width. Embolus long and coiled for three circles. Retrolateral tibial apophysis long and thin. Measurements of legs: I 4.2, II 3.6, III 3.9, IV 4.3. Color in alcohol ( Fig. 140): carapace dark yellow brown, with many white scales, lateral margins light yellow brown, with a light yellow brown stripe medially behind fovea; dorsal abdomen dark brown, anterior end and most of lateral margins light yellow, posterior end with a few paralleled chevron-like markings; ventral abdomen light yellow, with an indistinct middle stripe; legs light yellow with yellow brown annuli.

Female (paratype, UBC-SEM AR00130). Carapace length 1.9 (variation 1.8–1.9, n=5); abdomen length 1.9. Chelicera: also with two promarginal teeth and one retromarginal tooth. Measurements of legs: I 3.5, II 3.3, III 3.7, IV 4.2. Epigynum ( Figs 145–146): window large; median septum almost triangular with anterior part very narrow. Color in alcohol ( Fig. 141): similar to that of male.
