Etymology. This species is named after the type locality, Turret Range, Fiordland.

Diagnosis. This species can be distinguished from the other species of the misella speciesgroup by the following combination of characters: body larger, length 2.5–2.7 mm; male antennomeres 4–10 enlarged; eye larger, approximately one-half length of temple; shape of antennomeres and genitalia unique to species.

Description. Length 2.5–2.7 mm. Body reddish brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 58i ). Head: Round, as long as wide, widest across eyes ( Fig. 58i ). Male antennomere 1 approximately 1.5 times longer than wide, 2–10 subquadrate, 4–10 enlarged, 6–11 with tubercles. Female antennomere 2 longer than wide, 3 subquadrate, 4–5 longer than wide, 6–10 subquadrate, 6–11 with tubercles. Frontal rostrum rectangular, lobe continuous. Frontal sulcus reaching midpoint of eye. Posterior frontal fovea elongate. Eye prominent, approximately one-half length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Male elytra rectangular ( Fig. 58i ), elytra subquadrate in female and some males. Male meso- and metathorax trapezoidal, longer than wide, female and some males as long as wide. Abdomen: Male tergite IV with a pair of transverse patches of microtrichia, patches absent in females and some males. Aedeagus: Median lobe of genitalia twisted with membranous tube ( Fig. 59i ). Phallobase of median lobe symmetrical and rounded ( Fig. 59i ). Parameres asymmetrical, right longer than left, with setae apically ( Fig. 59i ).

Distribution. Fiordland, Marlborough, Marlborough Sounds, Southland ( Fig. 63 : black circles).

Habitat. Specimens of this species were collected by sifting grass, moss, and tussock litter.
