Type Material. Holotype. NEW ZEALAND: Central Otago: 1♂ ( NZAC), aedeagus dissected and mounted in balsam on a clear plastic card, “New Zealand CO Ailsa Craig Lammermoor Rng 7-Dec- 08”, “Sifted moss and tussock litter”, “ HOLOTYPE Sagola otagoensis Park and Carlton 2013 ”. The original label does not mention who collected the type specimen, but it was collected by J. Nunn. Paratypes (n = 11: 4 males; 7 females). NEW ZEALAND: Central Otago : 2♂♂ 7♀♀ ( JTN), same data as holotype ; 2♂♂ ( JTN), Ailsa Craig, Lammerlaw Rng, 14 XII 2008, J. Nunn .

Etymology. The species name is based on the biotic region of the type material, Central Otago.

Diagnosis. This species can be distinguished from the other species of the misella speciesgroup by the following combination of characters: body larger, length 2.6–2.8 mm; male antennomeres 4–10 enlarged; eye larger, approximately one-half length of temple; male abdominal ventrite V with round process medially; shape of antennomeres and genitalia unique to species; known from Central Otago of South Island.

Description. Length 2.6–2.8 mm. Body reddish brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 58j ). Head: Round, as long as wide, widest across eyes ( Fig. 58j ). 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, 3–10 subquadrate, 6–11 with tubercles. Frontal rostrum rectangular, lobes continuous. Frontal sulcus reaching midpoint of eye. Posterior frontal fovea long. Eye prominent, approximately onehalf length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra rectangular ( Fig. 58j ). Meso- and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV without patches of microtrichia. Male abdominal ventrite V with round process medially. Aedeagus: Median lobe of genitalia triangular, apical lobe rectangular vertically ( Fig. 59j–k ). Phallobase of median lobe symmetrical and rounded ( Fig. 59j ). Parameres asymmetrical, right longer than left, with setae apically ( Fig. 59j ).

Distribution. Central Otago ( Fig. 63 : triangle).

Habitat. Specimens of this species were collected by sifting tussock litter.
