Etymology. Named in honour of Fred Wanless, whose studies of basal salticids, including cocalodines, built the foundations for our modern understanding of the deep structure of salticid phylogeny. The unorthodox patronym " frewana   " was chosen to avoid confusion with the many species among related salticids with the more typical epithet " wanlessi ".

Diagnosis. A small cocalodine from tree trunks and branches, resembling small spartaeines such as Mintonia Wanless.   Males can be recognized by the large hooked median apophysis, much more prominent than the embolus ( Fig. 24 View FIGURES 20 – 30 ); females by the two posterior epigynal openings beside a central lobe ( Fig. 29 View FIGURES 20 – 30 ).

Description. Male (holotype). Carapace length 1.6; abdomen length 1.4. Chelicerae: small, vertical, with three promarginal and four retromarginal teeth. Intercheliceral sclerite not enlarged into a visible horn. Palpus ( Figs 24–26 View FIGURES 20 – 30 ): embolus hidden; begins at prolateral distal corner of bulb, goes dorsally into cymbium then retrolaterally and finally ventrally ( Fig. 25 View FIGURES 20 – 30 ) to end near the tip of the conductor and median apophysis. Median apophysis is the most easily visible dark sclerite; long and hooked. Conductor is membranous, and accompanies median apophysis. Tibia of first leg with three pairs of ventral macrosetae; first metatarsus with three pairs. Carapace of most common salticid form, with eyes not on tubercles. PME large. Colour: Mottled brown, with pale stripe around base of carapace, and pale longitudinal stripes ( Figs 20–21 View FIGURES 20 – 30 ). First legs darkest. Palpus clothed in white hairs.

Female (paratype, UBC – SEM AR 00017). Carapace length 1.9; abdomen length 2.1. Chelicerae: three promarginal and 3–4 retromarginal teeth. Palp with tarsal claw. Tibia of first leg with three pairs of ventral macrosetae; first metatarsus with three pairs. Epigynum ( Figs 29–30 View FIGURES 20 – 30 ) with openings near posterior margin. Carapace and eyes ( Figs 27–28 View FIGURES 20 – 30 ) as in male. Colour: as in male. There are two colour forms of female, the common one ( Fig. 23 View FIGURES 20 – 30 ) similar to the male, and a second paler form known from one female from each of the Paiam Forest and Mt. Gahavisuka   , having broad pale patch dorsally on thorax and abdomen ( Fig. 22 View FIGURES 20 – 30 ).

Natural history. Found only at fairly high elevation on tree trunks and branches ( Fig. 88 View FIGURES 87 – 92 ). Most were found by brushing tree trunks over a beating sheet. The trunks were not heavily covered with mosses.
