Description. Body length 2.9–3.1 mm. Head yellowish, infuscated discally; pronotum and elytra yellowish, dark brown discally; elytra with suture reddish, sides and apex widely yellowish; abdomen mostly dark brown, yellowish laterally and apically; antennal segments 1+2, palpi, and legs yellowish; antennal segments 3–11 reddish. Microsculpture absent. Iridescence absent. Very shiny, without metallic luster. Head. Labrum strongly transverse, slightly emarginate anteriorly. Antennae submoniliform, short: segment 1 (scape) short, stout, about 1.5x longer than its maximum width. Frontal furrows wide, deep, convergent. Eyes moderately convex; two setiferous punctures on inner side of each eye. Tempora slightly inflated (about one third as long as eyes). Mentum: medial tooth entire, rounded apically, moderately shorter than lateral lobes. Paraglossae membranous, prominent, slightly longer than ligula. Thorax. Pronotum strongly convex, coarsely punctate across base and finely punctate apically, unwrinkled, strongly transverse and cordate, widest before middle; apex subtruncate; anterolateral angles poorly developed, rounded; anterior bead incomplete, obsolete medially; sides strongly rounded, not sinuate posteriorly; lateral grooves absent; two setiferous punctures on each side; posterolateral angles acute, projected laterally; posterolateral carinae obsolete; laterobasal foveae well defined, coarsely punctate, moderately deep and wide, rounded, not prolonged forward, simple; posterior bead absent; sub-basal transverse impression well developed, coarsely punctate (with about 10 punctures); basal transverse impression well developed, coarsely punctate (with about 10 punctures); base subtruncate, much narrower than pronotal apex, about as wide as elytral base. Legs. Short. Elytra. Strongly convex, ovate, widest about middle. Basal margin incomplete, reaching about stria 4. Shoulders rounded. Sides strongly rounded. Scutellar striole obsolete. Striae replaced by rows of coarse punctures, very deep; row 1 complete; rows 2–7 incomplete; row 3 with three setiferous punctures. Recurrent stria long, blunt, directed apically toward row 5. Subapical seta present. Intervals moderately convex. Sutural apices obtuse. Abdomen. Last visible sternum (sternum VII): male with two apical ambulatory setae; female with four apical ambulatory setae. Aedeagus. Not seen (no specimen available for dissection).

Material examined. 4 specimens ( BMNH, NZAC).

Geographic distribution ( Fig. 114 ). South Island: BR –Punakaiki. NN –Westport.

Ecology. Lowland. Epigean. Wet forests (beech). Shaded ground. Nocturnal; hides during the day in moss, and under logs and stones.

Biology. Seasonality: October. Tenerals: March (BR). Predacious (based on mouthpart morphology).

Dispersal power. Subapterous (incapable of flight). Slow runner.

Collecting techniques. Sifting moss; lifting logs and stones.

Remark. Oopterus parvulus was described by Broun (1903: 610) based on two male syntypes mounted together on a white rectangular label (BMNH); the male on the left is selected as the lectotype, while the male on the right becomes a paralectotype. These type designations are made to preserve stability of nomenclature in the future.
