Etymology. This species is named for one of the enthusiastic supporters of this study, Leonie Clunie. She assisted with specimen access through loans and during the first author’ s visit to the New Zealand Arthropod Collection.

Diagnosis. This species can be distinguished from the other species of the misella speciesgroup by the following combination of characters: body larger, length 2.2–2.3 mm; male antennomeres 6–10 enlarged; male abdominal ventrite V medially flattened; shape of antennomeres and genitalia unique to species; only known from Secretary Island in Fiordland.

Description. Length 2.2–2.3 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 58h ). Head: Round, as long as wide, widest across eyes ( Fig. 58h ). Male antennomere 1 approximately 1.5 times longer than wide, 2–3 subquadrate, 4–5 longer than wide, 6–10 weakly enlarged, 6–11 with tubercles. Female antennomeres 2–7 longer than wide, 8–10 subquadrate, 8–11 with tubercles. Frontal rostrum rectangular, meeting each other. Frontal sulcus reaching midpoint of eye. Posterior frontal fovea oval. Eye prominent, approximately one-third length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra subquadrate ( Fig. 58h ). Meso- and metathorax trapezoidal, as long as wide. Abdomen: Male tergite IV without patches of microtrichia. Male abdominal ventrite V medially flattened. Aedeagus: Apical lobe of genitalia triangular ( Fig. 59h ). Phallobase of median lobe symmetrical and rounded ( Fig. 59h ). Parameres symmetrical blunt with setae apically ( Fig. 59h ).
