Etymology. Latin tortuosus (twisting), referring to the convoluted copulatory duct of vulva.

Diagnosis. Resembles Omoedus papuanus in body form, but differs from it by the color pattern ( Figs 159–164), the shape of the median septum of the epigynum ( Fig. 168), the thicker retrolateral tibial apophysis and the narrower but more spiraled embolus of the male palp ( Figs 165–166).

Description. Male (holotype, UBC-SEM AR00131). Carapace length 2.5 (variation 2.2–2.5, n=3); abdomen length 2.7. Chelicera ( Fig. 167): dark brown; with two promarginal teeth and one retromarginal tooth. Palp ( Figs 165–166): yellow brown. Retrolateral sperm duct loop occupying about three quarters of bulb width. Embolus long and coiled for more than seven circles. Retrolateral tibial apophysis long and finger-like. Tibia of first leg with four proventral and three retroventral macrosetae; metatarsus with two pairs of ventral macrosetae. Measurements of legs: I 7.2, II 5.2, III 5.4, IV 6.1. Color in alcohol ( Fig. 163): eye area dark, other regions of carapace red brown; abdomen dark brown, with some brownish spots; legs light yellow proximally and dark brown distally.

Female (paratype, UBC-SEM AR00132). Carapace length 2.2 (variation 2.1–2.3, n=5); abdomen length 2.6. Chelicera: with two promarginal teeth and one retromarginal tooth. Measurements of legs: I 4.1, II 3.8, III 4.5, IV 5.1. Epigynum ( Figs 168–169): window large; margins of median septum slightly convex. Color in alcohol ( Fig. 164): similar to that of male except the brownish spots on dorsal abdomen more irregular.

Natural history. Specimens were found in suspended leaf litter in forest.
