Etymology. Latin brevis (short), referring to the short embolus of male palp.

Diagnosis. Male can be easily distinguished from other species by the very short embolus ( Figs 315–316) and the long protrusion on the front surface of the chelicera ( Fig. 314). Female differs from Zabkattus trapeziformis in the median septum of the epigynum, which is not continuous with the edge of the window anteriorly ( Fig. 317), and the thicker and shorter copulatory duct ( Fig. 318).

Description. Male (holotype, UBC-SEM AR00115). Carapace length 1.4 (variation 1.3–1.4, n=3); abdomen length 1.1. Chelicera ( Fig. 314): red brown; front surface with a long protrusion at the distal half part laterally. Palp ( Figs 315–316): light yellow. Proximal tegular lobe present. Embolus short and slightly curved. Retrolateral tibial apophysis short with distal end hawk-beak shaped. Tibia of first leg with three pairs of ventral macrosetae; first metatarsus with two pairs. Measurements of legs: I 3.0, II 2.4, III 2.7, IV 2.8. Color in alcohol ( Fig. 312): carapace dark red brown with orange and white scales; abdomen gray brown with irregular light yellow markings, covered with orange and white scales; legs light yellow, with distinct gray brown markings.

Female (paratype, UBC-SEM AR00116). Carapace length 1.2 (variation 1.2–1.5, n=3); abdomen length 1.5. Tibia of first leg with three pairs of ventral macrosetae; first metatarsus with two pairs. Measurements of legs: I 2.3, II 2.2, III 2.5, IV 2.7. Epigynum ( Figs 317–318): window wide and oval; median septum not reaching anterior edge of the window. Copulatory duct well sclerotized and thick; spermatheca small. Color in alcohol ( Fig. 313): similar to that of male.

Natural history. Specimens were found on leaf litter in forest.
