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.
