description: <i>Thorelliola zabkai</i> sp. nov. Figs 261–271 <b>Type material.</b> 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 &amp; Aislan Tama Wanakipa Indiaf, WPM#08- 013 (UBC-SEM AR00106). Paratype: 1 female, same data as holotype (UBC-SEM AR00107). <b>Etymology.</b> The specific epithet is a patronym in honor of Dr. Marek &amp;Zdot;abka, who has made great contributions to the study of jumping spider systematics and biodiversity. <b>Diagnosis.</b> Female of this species can be distinguished from <i>T. crebra</i> and <i>T. squamosa</i> 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 <i>T. crebra</i> 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). <b>Description.</b> <i>Male</i> (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. <i>Female</i> (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. <b>Natural history.</b> Specimens were collected on tree trunks in forest.
