Oopterus aucklandicus Brookes, 1951: 23 . Type locality: Mount Raynal (Flat Topped Mountain), Auckland Islands [AU]. Synonymized by Johns 1974: 298 . Description . Body length 4.1–4.5 mm . Head, pronotum, elytra, and abdomen mostly dark brown; margins of pronotum reddish; lateral margins, suture, and apex of elytra reddish; abdomen reddish laterally and apically; antennae, palpi, and legs reddish; femora pale yellow. Microsculpture strong, isodiametric. Iridescence absent. Very shiny, with metallic luster (aeneous) on head, pronotum, and elytra. Head . Labrum strongly transverse, slightly emarginate anteriorly. Antennae submoniliform, short: segment 1 (scape) moderately long, about 2x longer than its maximum width. Frontal furrows wide, shallow, convergent. Eyes strongly convex; two setiferous punctures on inner side of each eye. Tempora moderately inflated (about half as long as eyes). Mentum: medial tooth bifid, moderately shorter than lateral lobes. Mentum-submentum suture absent (present in other zoline taxa). Ligula with six setae (two medial setae fused, four lateral setae free; as opposed to two fused setae only in other Pseudoopterus species ). Paraglossae membranous, prominent, about as long as ligula. Thorax . Pronotum strongly convex, impunctate, coarsely wrinkled discally (finely wrinkled in other Pseudoopterus species ), strongly transverse, slightly cordate, widest before middle; apex subtruncate; anterolateral angles poorly developed, rounded; anterior bead incomplete, obsolete medially; sides strongly rounded, slightly sinuate posteriorly; lateral grooves absent; two setiferous punctures on each side; posterolateral angles subrectangular; posterolateral carinae obsolete; laterobasal foveae well defined, impunctate, moderately deep, very wide, oblong, prolonged forward, simple; posterior bead absent; base emarginate, much narrower than pronotal apex, about as wide as elytral base. Legs . Short. Elytra . Moderately convex, ovate, widest about middle. Shoulders oblique. Sides strongly rounded. Scutellar striole absent. Striae complete, deep, impunctate or very finely punctate; stria 3 with three large setiferous punctures (small punctures in other Pseudoopterus species ). Recurrent stria long, blunt, directed apically toward stria 5 or 7. Intervals slightly convex. Sutural apices obtuse. Abdomen . Last visible sternum (sternum VII): male with two apical and two medial ambulatory setae; female with four apical ambulatory setae. Aedeagus . Lateral view ( Fig. 101 ): moderately arcuate, moderately widened in apical half; base strongly convex dorsally; middle moderately sinuate dorsally, strongly convex ventrally, with dorsal membranous area moderately wide, very long; apex subtriangular, slightly convex dorsally, moderately concave ventrally, with extreme tip narrow and long. Dorsal view: moderately wide, asymmetrical (ostium of membranous area deflected to right); apex deflected to the left; basal orifice wide, open anteriorly, moderately distant from membranous area. Parameres with three or four apical setae. Material examined . 173 specimens ( CMNZ , LUNZ , MONZ , NZAC ). Geographic distribution ( Fig. 152 ). Subantarctic Islands: AU . Ecology . Lowland, montane, subalpine, alpine. Epigean. Supralittoral zone; peaty wet forests ( Olearia , Metrosideros ), tussock grassfields; herbfields; fellfields. Open ground. Nocturnal; hides during the day in leaf litter, under logs and stones, and in peat. Gregarious. Biology . Seasonality: November, January–February, April, June, August. Tenerals: February. Predacious (based on mouthpart morphology). Occasionally infested with fungi (Laboulbeniales). Dispersal power . Subapterous (incapable of flight). Slow runner. Collecting techniques . Sifting leaf litter; lifting logs and stones; pitfall trapping; inspecting peat. References . Larochelle and Larivière 2001: 76 (as Oopterus plicaticollis ; catalogue; biology, dispersal power, ecology, geographic distribution, references), 2016: 21 (as Oopterus plicaticollis ; list). Remark . Pseudoopterus plicaticollis is the only New Zealand zoline species lacking a mentum– submentum suture.
