Type material. Holotype: male, PAPUA NEW GUINEA: Southern Highlands Province: Umgé , 5.304° S, 142.512° E, elev. 1450 m a.s.l., 15–19 July 2008, coll. W. Maddison & Aislan Tama Wanakipa Indiaf, WPM#08- 013 ( UBC-SEM AR00106 ) . Paratype: 1 female, same data as holotype ( UBC-SEM AR00107 ) .

Etymology. The specific epithet is a patronym in honor of Dr. Marek Żabka, who has made great contributions to the study of jumping spider systematics and biodiversity.

Diagnosis. Female of this species can be distinguished from T. crebra and T. squamosa by the more obscure guanine deposits in the eye area ( Figs 265–266) and the indistinctive secondary spermatheca ( Fig. 271). Male of this species differs from T. crebra in the longer embolus, the shape of the embolic disc, the narrower sperm duct loop, the thinner retrolateral tibial apophysis and the bump-like protuberance on the palpal femur ( Figs 267–269).

Description. Male (holotype, UBC-SEM AR00106). Carapace length 2.0; abdomen length 2.1. Clypeus with only ordinary fine setae. Chelicera: red brown; with two promarginal teeth and one bicuspid retromarginal tooth; without distal process on front surface. Endite: grayish brown; without lateral bulge. Palp ( Figs 267–269): yellow brown. Embolic disc almost rectangular with the retrolateral margin almost straight; embolus long and curved; loop of sperm duct almost half as wide as bulb. Tibia, patella and femur of palp with multiple macrosetae; femur with a hump near distal end pro-ventrally. Retrolateral tibial apophysis long and finger-like. Tibia of first leg with three pairs of ventral macrosetae; metatarsus with two pairs. Measurements of legs: I 4.8, II 4.1, III 4.8, IV 5.0. Color in alcohol ( Fig. 265): carapace gray brown, with lateral margins and posterior eye area light yellow, guanine deposit in eye area not obvious; abdomen light yellow, markings not distinct in the preserved specimen; legs light yellow with dark gray markings, first pair of legs darker than others.

Female (paratype, UBC-SEM AR00107). Carapace length 1.8; abdomen length 2.6. Chelicera: with two promarginal and one bicuspid retromarginal tooth. Tibia of first leg with three pairs of ventral macrosetae; metatarsus with two pairs. Measurements of legs: I 3.5, II 3.4, III 3.8, IV 4.4. Epigynum ( Figs 270–271): window large; opening to copulatory duct at posterior end of window laterally. Copulatory duct long and convoluted; secondary spermatheca not obvious, primary spermatheca small and spherical. Color in alcohol ( Fig. 266): similar to that of male, but lighter.

Natural history. Specimens were collected on tree trunks in forest.
