Etymology. This species is named after the type locality, Hunter Mts., Fiordland.

Diagnosis. This species can be distinguished from the other species of the misella speciesgroup by the following combination of characters: larger body, length 2.1–2.5 mm; male antennomeres 5–10 weakly enlarged; posterior frontal fovea elongate; male elytra subquadrate; male abdominal ventrite V medially flattened, VII small with acute process medially; shape of antennomeres and genitalia unique to species.

Description. Length 2.1–2.5 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 58f ). Head: Round, as long as wide, widest across eyes ( Fig. 58f ). Male antennomere 1 approximately 1.5 times longer than wide, 2 longer than wide, 3–10 subquadrate, 5–10 weakly enlarged, 6–11 with tubercles. Female antennomere 2 longer than wide, 3 subquadrate, 4 longer than wide, 5–10 subquadrate, 6–11 with tubercles. Frontal rostrum rectangular, lobes continuous. Frontal sulcus reaching midpoint of eye. Posterior frontal fovea elongate. Eye prominent, approximately one-third length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra subquadrate ( Fig. 58f ). Meso- and metathorax trapezoidal, as long as wide. Abdomen: Male tergite IV without patches of microtrichia. Male abdominal ventrite V medially flattened, VII small with acute process medially. Aedeagus: Apical lobe of genitalia divided, major lobe diamond-shaped ( Fig. 59f ). Phallobase of median lobe symmetrical and rounded ( Fig. 59f ). Parameres symmetrical, blunt with setae apically ( Fig. 59f ).

Distribution. Fiordland ( Fig. 62 : triangles).

Habitat. Specimens of this species were collected by sifting tussock litter and material from mats.
