Etymology. The species name is based on the biotic region of some of the type material, Fiordland.

Diagnosis. This species can be distinguished from the other species of the misella species-group by the following combination of characters: size larger, 2.6–3.0 mm; male antennomeres 4–10 enlarged; eye larger, approximately one-half length of temple; male abdominal ventrites V–VI medially flattened; shape of genitalia unique to species.

Description. Length 2.6–3.0 mm. Body reddish brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 58e ). Head: Round, as long as wide, widest across eyes ( Fig. 58e ). Male antennomere 1 approximately 1.5 times longer than wide, 2–10 subquadrate, 4–10 enlarged, 6–11 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 teardrop-shaped. Eye prominent, approximately one-half length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Male elytra rectangular ( Fig. 58e ), elytra subquadrate in females and some males. Male meso- and metathorax trapezoidal, longer than wide, females and some males as long as wide. Abdomen: Male tergite IV with pair of transverse patches of microtrichia reaching middle, patches absent in females and some males. Male abdominal ventrites V–VI medially flatten. Aedeagus: Apical lobe of genitalia acute ( Fig. 59e ). Phallobase of median lobe symmetrical and rounded ( Fig. 59e ). Parameres asymmetrical, right longer than left, with setae apically ( Fig. 59e ).

Distribution. Fiordland, Marlborough, Westland ( Fig. 62 : black circles).

Habitat. Specimens of this species were collected mostly by sifting forest litter.
