[= Mount] Anglem, 3000’ Stewart Island (typed) / 28.I.62 G. Kuschel (typed) / [male symbol] / HOLOTYPE [male symbol] Oopterus anglemensis Larochelle & Larivière, 2017 (red label; typed).” Paratypes : two females (AMNZ, NZAC) from the same locality as the holotype , bearing blue paratype labels. Description . Body length 6.0– 6.5 mm . Head, pronotum, elytra, and abdomen mostly black; base of pronotum reddish; lateral margins and suture of elytra reddish; abdomen reddish laterally and apically; antennae, palpi, and legs reddish. Microsculpture strong, isodiametric on head, very transverse (with microlines) on pronotum and elytra. Iridescence absent on head, very strong on pronotum and elytra. Very shiny, without metallic luster. 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 slightly convex; two setiferous punctures on inner side of each eye. Tempora moderately inflated (about half as long as eyes). Mentum: medial tooth entire, acute apically, moderately shorter than lateral lobes. Paraglossae membranous, prominent, slightly longer than ligula. Thorax . Pronotum moderately convex, impunctate, wrinkled discally, strongly transverse and cordate, widest before middle; apex subtruncate; anterolateral angles poorly developed, rounded; anterior bead incomplete, obsolete medially; sides strongly rounded, strongly sinuate posteriorly; lateral grooves absent; two setiferous punctures on each side; posterolateral angles subrectangular; posterolateral carinae absent; laterobasal foveae ill-defined, impunctate, shallow, very wide, prolonged forward, double; posterior bead absent; base subtruncate, much narrower than pronotal apex, slightly narrower than elytral base. Legs . Moderately long. Elytra . Moderately convex, subovate, widest about middle. Basal margin incomplete, reaching about stria 4. Shoulders obtuse. Sides moderately rounded. Scutellar striole obsolete. Striae complete, shallow, finely punctate; stria 3 with four or five setiferous punctures. Recurrent stria long, blunt, directed apically toward stria 5. Subapical seta present. Intervals subdepressed. Sutural apices obtuse. Abdomen . Last visible sternum (sternum VII): male with two apical ambulatory setae; female with four apical ambulatory setae. Aedeagus . Lateral view ( Fig. 95 ): moderately arcuate, not widened in apical half; base moderately biconvex dorsally; middle subparallel, almost straight dorsally, slightly concave ventrally, with dorsal membranous area moderately wide and very long; apex subtriangular, slightly biconcave dorsally, slightly concave ventrally, with extreme tip narrow and long. Dorsal view: narrow, asymmetrical (ostium of membranous area deflected to right); apex straight; basal orifice narrow, closed anteriorly, moderately distant from membranous area. Parameres with four or five apical setae. Material examined . 48 specimens ( AMNZ , CMNZ , LUNZ , NZAC ). Geographic distribution ( Fig. 120 ). Stewart Island: Freds Camp. Freshwater. Mount Anglem. Oban. Ocean Beach. Pegasus Creek. Port Pegasus. Port William. Table Hill. Twilight Bay. Ecology . Lowland, montane, subalpine, alpine. Epigean. Wet forests (broadleaf, podocarp). Shaded ground. Nocturnal; hides during the day under logs, as well as in moss and leaf litter. Gregarious. Biology . Seasonality: January–February. Tenerals: February. Predacious (based on mouthpart morphology). Dispersal power . Subapterous (incapable of flight). Moderate runner. Collecting techniques . Lifting logs; sifting moss and leaf litter. Remarks . This species is named after the type locality Mount Anglem (Stewart Island) and the Latin suffix - ensis , denoting a place, locality, or country. Oopterus anglemensis is morphologically close to O. nanus . In addition to diagnostic characters of the male genitalia, O. anglemensis has the following distinguishing features: body length 6.0– 6.5 mm ; pronotum strongly cordate, laterobasal foveae ill- defined; legs moderately long; elytra moderately convex, subovate, sides moderately rounded. The two species are allopatric: O. anglemensis is restricted to Stewart Island, while O. nanus occurs in southern areas of the South Island (CO, OL).
