 Amarotypus glasgowensis Larochelle and Larivière, new species. Holotype: male (AMNZ) labeled “[NEW ZEALAND NN] Mt. [=Mount] Glasgow Westland 4000′ 23.2.38 (hand-written) / C.E. Clarke Collection (typed) / AMNZ 31973 Auckland Museum New Zealand (green label; typed) / HOLOTYPE ♂ Amarotypus glasgowensis Larochelle & Larivière, 2022 (red label; typed).”   
 Description. Body length 6.7 mm; ovate. Head, pronotum, and elytra rufotestaceous; abdomen rufopiceous; antennae, palpi, and legs rufotestaceous. Microsculpture weak and isodiametric (almost granulate) on head, weak and isodiametric on pronotum, obsolete and moderately transverse on elytra. Iridescence present on elytra. Shiny on head, pronotum, and elytra. Metallic luster absent. Head. Labrum moderately transverse. Eyes slightly convex. Thorax. Pronotum moderately convex, obsoletely punctate and wrinkled across base, trapezoid, widest basally; apex moderately emarginate; anterolateral angles poorly developed, angulate; anterior bead complete; sides moderately rounded, moderately sinuate posteriorly; lateral beads narrow, slightly widened from apex to base; lateral depressions absent anteriorly, wide posteriorly; posterolateral angles acute, moderately projected laterally; laterobasal foveae with outer fovea oblong, narrow, shallow, and inner fovea oblong, moderately wide, moderately deep; posterior bead obsolete. Legs. Pro- and mesotarsomeres 1–4 of male moderately dilated. Elytra. Ovate. Fused along suture (hindwings vestigial). Strongly convex. Shoulders slightly obtuse. Sides strongly rounded. Striae shallow, finely punctate; stria 3 with two poorly developed, fine setiferous punctures. Scutellar striole very long (about two-thirds of elytral length). Intervals subdepressed. Umbilicate series with 15 setiferous punctures. Apices obtusely rounded. Aedeagus. Not examined.   
 Material examined. 1 specimen (AMNZ).   
 Geographic distribution (Fig. 42). South Island: NN –Mount Glasgow.   
 Ecology. Alpine. Epigean. Open ground. Probably nocturnal.   
 Biology. Seasonality: February. Predacious (based on mouthpart morphology).   
 Dispersal power. Subapterous (incapable of flight).   
 Collecting technique. Unknown.   
 Remarks. This species is named after the type locality Mount Glasgow (NN) and the Latin suffix – ensis, denoting a place, locality, or country. Due to the paucity of material, no male was dissected in this study. However, there is no ambiguity regarding the identity of this taxon. Amarotypus glasgowensis is morphologically close to A. takaheensis from which it can be distinguished as follows: dorsal body rufotestaceous; antennae rufotestaceous; elytra with moderately transverse microsculpture, striae shallow and finely punctate, stria 3 with two setiferous punctures. The two species are allopatric: A. glasgowensis is known only from the northwestern South Island (NN), while A. takaheensis occurs in the southwestern South Island (FD).
