- <p><b><i>Maungazolus ranatungae</i> new species</b></p><p>Fig. 64, 109, 117</p><p>Holotype: male (NZAC) labeled: “[NEW ZEALAND MB] Fell Pk. [= Mount Fell] 1296m (typed) / Richmond Ra. [= Range] (typed) / 13 March 69 J.C. Watt (typed) / Litter (typed) 69/113 (hand-written) / [male symbol] / HOLOTYPE [male symbol] <i>Maungazolus ranatungae</i> Larochelle & Larivière, 2017 (red label; typed).” Paratypes: one female (NZAC) and one male (LUNZ) from the same locality as the holotype, bearing blue paratype labels.</p><p><b>Description</b>. Body length 2.9–3.4 mm. Head and pronotum dark brown; elytra yellowish, dark brown discally, base dark brown medially, sides and apex widely pale yellow; abdomen mostly reddish piceous, reddish laterally and apically; antennae, palpi, and legs reddish; antennal segments 1+2 yellow; femora bright yellow, strongly contrasting with tibiae. Microsculpture absent. Iridescence absent. Very shiny, without metallic luster. <b>Head</b>. 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 slightly convex; two setiferous punctures on inner side of each eye. Tempora moderately inflated (about half as long as eyes). Mentum: medial tooth entire, slightly emarginate apically, moderately shorter than lateral lobes. Paraglossae membranous, prominent, slightly longer than ligula. <b>Thorax</b>. Pronotum strongly convex, coarsely punctate across base, unwrinkled, moderately 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 subrectangular; posterolateral carinae absent; laterobasal foveae well defined, coarsely punctate, very deep, moderately wide, rounded, not prolonged forward, simple; posterior bead absent; sub-basal transverse impression replaced by two foveolae; basal transverse impression well developed, coarsely punctate (with 10 to 12 punctures); base emarginate, much narrower than pronotal apex, about as wide as elytral base. <b>Legs</b>. Short. <b>Elytra</b>. Strongly convex, subovate, widest about middle. Basal margin incomplete, reaching about stria 4. Shoulders rounded. Sides strongly rounded. Scutellar striole present. Striae finely punctate; stria 1 complete, very deep; striae 2–5 incomplete, shallow; striae 6–7 obsolete; stria 3 with three setiferous punctures. Recurrent stria long, blunt, directed apically toward stria 5. Subapical seta present. Intervals subdepressed. Sutural apices obtusely rounded. <b>Abdomen</b>. Last visible sternum (sternum VII): male with two apical ambulatory setae; female with four apical ambulatory setae. <b>Aedeagus</b>. Lateral view (Fig. 109): rather strongly arcuate, not widened in apical half; base moderately convex dorsally; middle slightly concave dorsally, slightly convex ventrally, with dorsal membranous area very wide and long; apex subtriangular, moderately convex dorsally, slightly concave ventrally, with extreme tip wide and short. Dorsal view: very narrow, almost thin, asymmetrical (ostium of membranous area deflected to right); apex straight; basal orifice narrow, very close to membranous area. Parameres with two apical setae.</p><p><b>Material examined</b>. 49 specimens (LUNZ, NZAC).</p><p><b>Geographic distribution</b> (Fig. 117). North Island: WN–Tararua Range (Dundas Ridge Hut; Otaki Forks, Judd Ridge). South Island: MB –Mount Fell. Mount Johnson. NN –Abel Tasman National Park, Moa Park. SD–Mount Stokes.</p><p><b>Ecology</b>. Montane, alpine. Epigean. Mostly forests (beech); tussock grasslands. Shaded or open ground. Nocturnal; hides during the day in leaf litter and tussock litter. Gregarious.</p><p><b>Biology</b>. Seasonality: October–December, March. Predacious (based on mouthpart morphology).</p><p><b>Dispersal power</b>. Subapterous (incapable of flight). Slow runner.</p><p><b>Collecting techniques</b>. Sifting leaf litter and tussock litter.</p><p><b>Remarks</b>. This species is named after Dhahara Ranatunga (Auckland War Memorial Museum, Auckland) for her special help in our entomological studies. <i>Maungazolus ranatungae</i> is morphologically close to <i>M. tararuaensis</i>. In addition to diagnostic characters of the male genitalia, <i>M. ranatungae</i> has the following distinguishing features: head and pronotum dark brown; elytra yellowish, dark brown discally; abdomen mostly reddish piceous; mentum tooth slightly emarginate apically; pronotum moderately transverse and cordate, coarsely punctate across base; elytra with striae finely punctate and intervals subdepressed. <i>M. ranatungae</i> occurs in the south of the North Island (WN) and northern areas of the South Island (MB, NN, SD), while <i>M. tararuaensis</i> is only found in the south of the North Island (WN). <i>M. ranatungae</i> is the only zoline species known from both North and South Islands.</p>
