Jan. 70 J. McBurney (typed) / moss (typed) 70/69 (hand-written) / [male symbol] / HOLOTYPE [male symbol] Oopterus discoideus Larochelle & Larivière, 2017 (red label; typed).” Paratypes : two females (LUNZ, NZAC) from the same locality as the holotype , bearing blue paratype labels. Description . Body length 3.4–4.2 mm . Head, pronotum, elytra, and abdomen mostly testaceous; disc of head dark rufous; base and disc of pronotum dark rufous; a dark rufous oblong vitta present on each elytron; abdomen dark rufous medially; antennae, palpi, and femora pale yellow; femora (base), tibiae, and tarsi reddish. Microsculpture absent. Iridescence absent. 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, shallow, convergent. Eyes subdepressed; a single setiferous puncture on inner side of each eye (posteriorly). Tempora moderately inflated (about half as long as eyes). Mentum: medial tooth entire, acute apically, moderately shorter than lateral lobes. Paraglossae membranous, prominent, about as long as ligula. Thorax . Pronotum strongly convex, obsoletely punctate across base, wrinkled discally, strongly transverse, widest about middle; apex subtruncate; anterolateral angles poorly developed, obtusely rounded; anterior bead incomplete, obsolete medially; sides strongly rounded, not sinuate posteriorly; lateral grooves absent; setiferous punctures absent on each side; posterolateral angles obtuse; posterolateral carinae blunt, very long (about as long as adjoining foveae); laterobasal foveae well defined, virtually impunctate, very deep and wide, subrectangular, not prolonged forward, double; posterior bead absent; base subtruncate, about as wide as pronotal apex and elytral base. Legs . Moderately long. Elytra . Strongly convex, ovate, widest about middle. Basal margin complete, reaching about scutellum. Shoulders obtuse. Sides strongly rounded. Scutellar striole present. Striae complete, very deep, coarsely punctate; striae 2–7 shallower apically; interval 3 with three setiferous punctures. Recurrent stria long, blunt, directed apically toward stria 5. Subapical seta present. Intervals strongly convex. 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. 74 ): moderately arcuate, strongly widened in apical half; base strongly biconvex dorsally; middle moderately convex dorsally, slightly concave ventrally, with dorsal membranous area moderately wide and very long; apex triangular, straight dorsally, slightly concave ventrally, with extreme tip narrow, long, and curved downward. Dorsal view: narrow, asymmetrical (ostium of membranous area deflected to left); apex straight; basal orifice narrow, closed anteriorly, moderately distant from membranous area. Parameres with five apical setae. Material examined . 8 specimens ( JNNZ , LUNZ , NZAC ). Geographic distribution ( Fig. 125 ). South Island: FD –Fiordland National Park (Borland Saddle; Turret Range, Percy Stream; Wilmot Pass, Spey River; Wolfe Flat). Ecology . Montane. Endogean. Wet forests (beech). Shaded ground. Nocturnal; hides during the day in thick leaf litter and moss. Biology . Seasonality: January–February. Predacious (based on mouthpart morphology). Occasionally infested with fungi (Laboulbeniales). Dispersal power . Subapterous (incapable of flight). Moderate runner. Collecting techniques . Sifting leaf litter and moss. Remarks . This species name is based on the Latin adjective discoideus (discoid), referring to the discal color-pattern on head, pronotum, and elytra. Oopterus discoideus is morphologically close to O. marrisi . In addition to diagnostic characters of the male genitalia, O. discoideus has the following distinguishing features: body length 3.4–4.2 mm ; head, pronotum, and elytra mostly testaceous; eyes subdepressed; tempora moderately inflated (about half as long as eyes); pronotum strongly convex, sides strongly rounded, not sinuate posteriorly, laterobasal foveae subrectangular. Both species are known only from the Fiordland region (South Island).
