Retrolateral tibial apophysis short, shaped like a bird beak. Measurements of legs: I 1.8, II 1.2, III 1.5, IV 1.6. Color in alcohol (Fig. 205): carapace dark to dark brown, without distinct markings; abdomen light gray brown to light brown, with three parallel chevron-shaped dark markings at posterior part, posterior end of abdomen dark; venter of abdomen light brown; legs light yellow.

Female ( paratype, UBC-SEM AR00064). Carapace length 0.8; abdomen length 0.7. Measurements of legs: I 1.5, II 1.2, III 1.4, IV 1.5. Epigynum (Figs 209 – 210): without distinct window structure, posterior part with a transverse margin; opening to copulatory duct anterior to spermatheca. Copulatory ducts short; spermathecae oval.
