Description. Body length 7.7–9.8 mm; stout. Head, pronotum, and elytra black; abdomen rufopiceous, lateral margins rufous; antennae and palpi rufotestaceous; femora rufopiceous; tibiae and tarsi rufotestaceous. Microsculpture weak and isodiametric on head, strong and moderately transverse on pronotum, strong and very transverse (with microlines) on elytra. Iridescence present on pronotum and elytra. Shiny on head, pronotum, and elytra. Head. Eyes moderately large, moderately convex. Tempora not inflated. Frons wrinkled (with oblique strioles). Mentum with median tooth subtruncate apically. Palpi with terminal segment truncate apically. Thorax. Pronotum slightly convex, obsoletely wrinkled mediobasally, subquadrate, moderately wide compared to elytra, widest before middle; apex slightly emarginate; anterolateral angles poorly developed, obtuse; sides moderately rounded anteriorly, nearly straight posteriorly; lateral beads mostly narrow, strongly widened near posterolateral angles; two setiferous punctures on each side (anteriorly and posteriorly), each anterior setiferous puncture close to lateral bead, distant by about one puncture width; median line incomplete apically, complete basally; posterolateral angles moderately obtuse; laterobasal foveae single, shallow, parallel; posterior bead incomplete, obsolete medially; base moderately emarginate, about as wide as apex. Tip of scutellum strongly projected behind elytral base. Prosternum wrinkled throughout. Elytra. Subovate, widest about middle, moderately convex. Basal margin straight or slightly arcuate, complete, reaching scutellum. Shoulder tooth well developed, obtuse. Sides strongly rounded. Scutellar setiferous pore absent. Striae shallow, deepening apically, complete basally. Intervals depressed, becoming convex apically; interval 3 without setiferous puncture. Umbilicate series with 15 setiferous punctures separated into two major groups (7+8). Subapical sinuations feeble. Apices obtuse. Abdomen. Sternum VII of male without dense coarse punctures medially. Aedeagus. Lateral view ( Fig. 16 ): moderately arcuate, moderately wide; base slightly concave dorsally, with basal bead; middle moderately convex dorsally, strongly convex ventrally; apex strongly concave dorsally and ventrally, with extreme tip rather narrow, moderately long, strongly curved downward. Dorsal view ( Fig. 23 ): apex very wide, truncate, not deflected to the left.

Material examined. 17 specimens ( NHMUK, NZAC).

Geographic distribution ( Fig. 50 ). North Island: WA–Puketoi State Forest. Putangirua Stream, Cape Palliser. WN–Cross Creek, west of Lake Wairarapa. Featherston. Lake Wairarapa Reserve (west of). Opiki (Poplar Road, Manawatu [River]). Rimutaka Forest Park (Five-Mile Loop Track; Orongorongo Track).

Ecology. Lowland. Epigean, silvicolous, xerophilous or hygrophilous. Wet or dry forests (beech, podocarp). Shaded ground. Nocturnal; hides during the day under stones and logs.

Biology. Seasonality: September, January–March, June. Tenerals: September. Predacious (based on mouthpart morphology). Occasionally infested by fungi (Laboulbeniales).

Dispersal power. Subapterous. Moderate runner.

Collecting technique. Turning logs and stones.

Remarks. In addition to diagnostic characters of the male genitalia, C. rufipes has the following distinguishing features: microsculpture very transverse (with microlines) on elytra; terminal segment of palpi truncate apically; pronotum with sides nearly straight posteriorly, median line complete basally, lateral beads mostly narrow, strongly widened near posterolateral angles; elytra subovate, sides strongly rounded; tip of scutellum strongly projected behind elytral base. This species occurs in the south of the North Island (WA, WN).
