Description. Body length 13.0– 14.2 mm. Head, pronotum, and elytra piceous black; abdomen dark brown; antennal segments 1–4 piceous black, 5–11 reddish; palpi reddish; femora and tibiae piceous black; tarsi reddish. Microsculpture isodiametric on head, moderately transverse on pronotum, and isodiametric on elytra. Iridescence absent. Very shiny. Head. Mandibles moderately curved anteriorly. Labrum moderately transverse, slightly emarginate anteriorly. Thorax. Pronotum subdepressed, impunctate, deeply wrinkled on disc and across base, narrow, widest before middle; apex slightly emarginate; anterolateral angles poorly developed, rounded; anterior bead complete; sides strongly rounded anteriorly, strongly sinuate posteriorly; lateral beads complete; lateral depressions moderately wide anteriorly, much widened posteriorly; posterolateral angles subrectangular; laterobasal foveae very deep and wide, prolonged forward; posterior bead incomplete, obsolete medially; base emarginate. Legs. Metatarsomeres 5 setose ventrally (with short setae). Elytra. Subdepressed, not sloping down toward apex, oblong. Sides slightly rounded. Scutellar striole impunctate. Striae deep, impunctate. Intervals subdepressed; interval 3 with three shallow, minute setiferous punctures. Subapical sinuations feeble. Aedeagus. Lateral view ( Fig. 80 View Figures 80–86 ): base strongly convex dorsally, with basal lobe narrow; middle moderately wide in apical half, moderately convex dorsally, strongly concave ventrally, with dorsal membranous area moderately wide in apical half and very long; apex strongly rounded dorsally, slightly concave ventrally, with extreme tip moderately wide and very long.

Material examined. 157 specimens ( AMNZ, BMNH, CMNH, JNNZ, LUNZ, MNHN, MONZ, NZAC).

Geographic distribution ( Fig. 159 View Figures 154–159 ). North Island: AK, BP, CL, GB, HB, ND, RI, TK, TO, WN. South Island: BR, CO, DN, FD, KA, MB, MC, MK, NC, NN, OL, SD, SL, WD. Stewart Island.

Ecology. Lowland, montane. Epigean, arboreal. Mostly wet open forests (broadleaf, podocarp, beech), swamp forests, shrublands, scrublands, forest edges, and tree plantations (pine); tussock grasslands and pastures. Associated with streams. Mostly open ground. Nocturnal; hides during the day under logs and stones.

Biology. Seasonality: September–March, May, July–August. Tenerals: November–January, March. Predacious (based on mouthpart morphology). Predators: Feral cats. Occasionally infested with mites and fungi (Laboulbeniales). Defense mechanism: when alarmed, the adult emits a burnt chocolate-like smell.

Dispersal power. Macropterous. Occasional flier to artificial lights. Swift runner. Occasional climber (on trees). Favored by human activities.

Collecting techniques. Turning logs and stones.
