I. Agnarsson. Etymology. The specific epithet is a patronym in honor of Dr. Ingi Agnarsson, who collected specimens of this species and provided other material for this study. Diagnosis. Differs from other species by the absence of obvious anterior arch of the epigynum ( Figs 295–296 ); the presence of a large protrusion at the distal end of the tegulum, the narrower embolic spiral, and the shape of the retrolateral tibial apophysis of the male palp ( Figs 292–293 ). Description. Male ( holotype , UBC-SEM AR00111). Carapace length 1.6 (variation 1.6–1.8, n=2); abdomen length 1.5. Chelicera: dark brown; with two promarginal teeth and one unident retromarginal tooth. Palp ( Figs 292–293 ): cream to light brown, with dark pigments. Embolus relatively wide and slightly coiled; retrolateral sperm duct loop present and wide; proximal tegular lobe absent. Retrolateral tibial apophysis with two branches near the tip. First pair of legs with three pairs of ventral macrosetae on tibia. Measurements of legs: I 2.9, II 2.4, III 3.9, IV 3.8. Color in alcohol ( Fig. 290 ): carapace dark brown, with two white patches within eye area and one white patch right behind fovea composed of white scales; lateral margins with white stripes also composed of white scales; abdomen pale yellow, with two wide lateral stripes and one narrow medial stripe, all dark brown in color, ventral abdomen pale yellow with a wide dark stripe medially; legs cream without distinct markings. Female ( paratype , UBC-SEM AR00112). Carapace length 1.8 (variation 1.6–1.8, n=3); abdomen length 2.2. Chelicera ( Fig. 294 ): with two promarginal teeth and one unident retromarginal tooth. Tibia of first leg with five ventral macrosetae. Measurements of legs: I 2.9, II 2.8, III 3.9, IV 3.7. Epigynum ( Figs 295–296 ): window relatively small, at anterior part of epigynal plate; opening to copulatory duct at posterior rim of the window. Copulatory duct wide and not coiled; spermatheca long and kidney-like. Color in alcohol ( Fig. 291 ): similar to that of male except without white stripes at lateral margins of carapace.
