Description. Body length 16.5–20.2 mm. Head, pronotum, elytra, and abdomen black; antennal segments 1–3 rufopiceous, segments 4–11 reddish; palpi reddish; legs dark rufous. Microsculpture moderately transverse on head, very transverse (with microlines) on pronotum, and moderately transverse on elytra. Iridescence present on pronotum. Very shiny on head and pronotum, moderately shiny on elytra. Head. Moderately wide. Mandibles very long (about three times as long as labrum), slightly curved anteriorly. Labrum moderately transverse, slightly or moderately emarginate anteriorly. Eyes somewhat smaller than in other species. Tempora moderately inflated and very long (much longer than length of eyes). Submentum with two setae. Thorax. Pronotum slightly convex, obsoletely punctate mediobasally, obsoletely wrinkled on disc, moderately wide and cordate, widest before middle; apex strongly emarginate; anterolateral angles well developed, obtusely rounded; anterior bead incomplete, obsolete medially; sides moderately rounded, moderately sinuate posteriorly; lateral beads incomplete, obsolete basally; lateral depressions wide; posterolateral angles straight or slightly acute and extended laterally, obtuse at extreme apex; laterobasal foveae moderately deep, very wide, prolonged forward; posterior bead complete; base convex. Apex of prosternum pubescent. Legs. Very long. Metacoxae with three posteroventral setae. Metafemora with three posteroventral setae. Meso- and metatarsomeres 1–4 well developed, tricarinate dorsally, deeply bisulcate laterally. Metatarsomeres 4 strongly bilobed and asymmetrical apically. Metatarsomeres 5 with several longitudinal wrinkles dorsally (without wrinkles in other species). Elytra. Strongly convex, sloping down toward apex, subovate. Basal margin almost complete, reaching about stria 1 (complete, reaching about scutellum in other species). Shoulders strongly rounded. Sides moderately rounded. Scutellar setiferous pore visible. Scutellar striole punctate. Striae deep, coarsely punctate. Intervals slightly convex dorsally, moderately convex laterally. Umbilicate series with 17–19 setiferous punctures. Subapical sinuations moderately strong. Apices mucronate. Abdomen. Sterna IV–VI: both sexes with two long apical ambulatory setae. Sternum VII (last visible sternum): male with two long apical ambulatory setae; female with six long apical ambulatory setae. Aedeagus. Lateral view ( Fig. 94 ): base moderately convex dorsally, with basal lobe very wide; middle moderately concave dorsally, moderately concave with a slight convexity before apex ventrally, with dorsal membranous area strongly widened in apical half and moderately long; internal sac without scale-like sclerites; apex strongly convex dorsally, slightly concave ventrally, with extreme tip narrow and very long. Dorsal view: moderately wide, asymmetrical (ostium of membranous area deflected to the left); basal bulb close to membranous area.

Material examined. 229 specimens ( AMNZ, BMNH, JNNZ, LUNZ, MNHN, MONZ, NZAC).

Geographic distribution ( Fig. 151 ). North Island: AK, BP, CL, ND, TK, WO.

Ecology. Lowland, montane. Epigean, arboreal. Wet forests (broadleaf, podocarp, tree ferns) and tree plantations (pine). Associated with streams and logs. Shaded ground; wet soil. Nocturnal; hides during the day under logs and in rotten logs, also under fallen trees.

Biology. Seasonality: Throughout the year. Tenerals: October–January, April. Predacious (based on mouthpart morphology). Regularly infested with mites. Occasionally infested with fungi (Laboulbeniales).

Dispersal power. Subapterous (incapable of flight). Swift runner. Occasional climber (on logs).

Collecting techniques. Pitfall trapping; turning and breaking logs.

Remarks. Chaudoir described Colpodes crenatus from two specimens, one of which (a male) could be seen (MNHN) and is here designated as lectotype in order to preserve stability of nomenclature in the future. Examination of the types of Calathus deformipes and Anchomenus (Platynus) cheesemani revealed them to be conspecific with Kupeplatynus crenatus .
