Type material. Holotype: male, PAPUA NEW GUINEA: Southern Highlands Province: Tualapa, near Wanakipa , 5.283° S, 142.498° E, elev. 1000–1100 m a.s.l., 11–22 July 2008, forest interior and river side, coll. W. Maddison & Luc Fimo Tuki, WPM#08-008 ( UBC-SEM AR00095 ) . Paratypes: 1 female, same data as holotype ( UBC-SEM AR00096 ) ; 7 males in two vials, same data as holotype .

Etymology. The specific epithet is a patronym in honor of Dr. F. R. Wanless, who made great contributions in the study of jumping spider systematics, and revised this genus.

Diagnosis. Similar to Sobasina cutleri Berry, Beatty & Prószyṅski, 1998 and S. platypoda Berry, Beatty & Prószyṅski, 1998 , but differs from S. cutleri in the presence of ventral fringes on the male first leg ( Fig. 201), the relatively wider palpal bulb ( Fig. 202), and the shape of the vulva ( Fig. 204); and from S. platypoda in the shape of the epigynum and vulva ( Figs 203–204).

Description. Male (holotype, UBC-SEM AR00095). Carapace length 1.2 (variation 1.2–1.5, n=8); abdomen length 1.1. Carapace with many small punctures, and a hump at posterior part. Chelicera ( Fig. 200): yellow brown; with two promarginal teeth and one bicuspid retromarginal tooth. Palp ( Fig. 202): light yellow brown. Embolus not coiled. Retrolateral tibial apophysis finger-like. First pair of legs robust, with fringes on ventral tibia; tibia with four proventral and five retroventral macrosetae (some specimens with five pairs of ventral macrosetae on first tibia); metatarsus with three proventral and two retroventral macrosetae (some specimens with three pairs of ventral macrosetae on first metatarsus). Measurements of legs: I 2.0, II 1.5, III 1.5, IV 1.9. Color in alcohol ( Fig. 198): carapace dark brown to red brown; dorsal abdomen slightly constricted at 1/3 from anterior end; abdomen brown with a sandy yellow band at constriction; first pair of legs yellow brown, with tarsus and metatarsus light yellow; other legs light yellow to light brown.

Female (paratype, UBC-SEM AR00096). Carapace length 1.5; abdomen length 1.5. Chelicera: with two promarginal teeth and one bicuspid retromarginal tooth. Tibia of first leg with four proventral and five retroventral macrosetae; metatarsus with three pairs of ventral macrosetae. Measurements of legs: I 2.7, II 2.1, III 2.2, IV 3.1. Epigynum ( Figs 203–204): without window. Copulatory duct long and tubular, without accessory gland; spermatheca tubular. Color in alcohol ( Fig. 199): darker than that of male.

Natural history. Specimens were collected by beating forest understory, possibly with suspended litter.
