Description. Body length 4.6–5.0 mm. Head, pronotum, elytra, and abdomen mostly piceous black; base of head and pronotum reddish; base, lateral margins, suture, and apex of elytra reddish; abdomen yellow laterally and apically; antennae, palpi, and legs pale red; femora pale yellow. Microsculpture mostly absent on head (strong and isodiametric basally), absent on pronotum, strong and very transverse (with microlines) on elytra. Iridescence absent on head and pronotum, very strong on elytra. Very shiny, with metallic luster (aeneous) on elytra. Head. Labrum strongly transverse, slightly emarginate anteriorly. Antennae submoniliform, moderately long: segment 1 (scape) moderately long, about 2x longer than its maximum width. Frontal furrows wide, deep, convergent. Eyes moderately convex; a single setiferous puncture on inner side of each eye (posteriorly). Tempora not inflated. Mentum: medial tooth entire, acute apically, moderately shorter than lateral lobes. Paraglossae membranous, prominent, about as long as ligula. Thorax. Pronotum moderately convex, coarsely punctate across base, wrinkled discally, strongly transverse, moderately cordate, widest before middle; apex subtruncate; anterolateral angles poorly developed, rounded; anterior bead incomplete, present near anterolateral angles; sides strongly rounded, moderately sinuate posteriorly; lateral grooves moderately to very deep, very long (as long as pronotum); setiferous punctures absent on each side; posterolateral angles rectangular; posterolateral carinae sharp, very long (about as long as adjoining foveae); laterobasal foveae well defined, coarsely punctate, very deep, moderately wide, square, not prolonged forward, simple; posterior bead absent; base emarginate, about as wide as pronotal apex and elytral base. Legs. Moderately long. Elytra. Moderately convex, subovate, widest about middle. Basal margin incomplete, reaching about stria 4. Shoulders moderately rounded. Sides moderately rounded. Scutellar striole obsolete. Striae incomplete, mostly obsolete; stria 1 deep; striae 2–4 shallow, virtually impunctate; interval 3 with three setiferous punctures. Recurrent stria long, sharp, directed apically toward stria 5. Subapical seta present. Intervals subdepressed. Sutural apices obtusely rounded. Abdomen. Last visible sternum (sternum VII): male with two apical ambulatory setae; female with four apical ambulatory setae. Aedeagus. Lateral view ( Fig. 78 ): strongly arcuate, moderately widened in apical half; base strongly convex dorsally; middle moderately convex dorsally, rather straight ventrally, with dorsal membranous area moderately wide and rather long; apex subtriangular, subangulate dorsally, slightly concave ventrally, with extreme tip wide and short. Dorsal view: narrow, symmetrical (ostium of membranous area dorsal); apex straight; basal orifice narrow, closed anteriorly, close to membranous area. Parameres with three or four apical setae.

Material examined. 77 specimens ( AMNZ, BMNH, JNNZ, LUNZ, NZAC).

Geographic distribution ( Fig. 127 ). North Island: BP, HB, ND, TK, TO, WA, WN.

Ecology. Lowland, montane, subalpine. Epigean-arboreal. Wet forests (beech, broadleaf, podocarp). Shaded ground. Nocturnal; active at night on tree trunks; hides during the day under the loose bark of fallen trees, in fallen rotten branches and logs. Gregarious.

Biology. Seasonality: throughout the year, except October. Tenerals: December–March. Predacious (based on mouthpart morphology).

Dispersal power. Subapterous (incapable of flight). Moderate runner. Occasional climber on trees.

Collecting techniques. Lifting loose bark of fallen trees; breaking rotten branches and logs; fogging logs; pitfall trapping.
