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

Diagnosis. This species can be distinguished from the other species of the major species-group by the following combination of characters: body length 1.9–2.1 mm; eye one-half length of temple; ventral temple of male head with depressed and projecting temporal lobe and surface weakly concave; shape of antennomeres and genitalia unique to species; found from South Island.

Description. Length 1.9–2.1 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler (Fig. 66f). Head: Male head triangular, widest across temples (Fig. 66f). Female head bluntly triangular, widest across eyes. Ventral temple of male head with depressed and projecting temporal lobe and surface weakly concave (Fig. 66t). Thick, dense setae on male gular depression. Antennomere 1 approximately 1.5 times longer than wide, 2 longer than wide, 3 subquadrate, 4–5 longer than wide, 6–10 subquadrate. Frontal sulcus shallow, reaching midpoint of eye. Anterior frontal fovea oval, partially covered by frontal rostrum, posterior frontal fovea oval. Eye large and prominent, one-half length of temple. Thorax: Prosternum as long as wide, widest at one-third length. Male elytra rectangular (Fig. 66f), female elytra subquadrate. Male meso- and metathorax trapezoidal, longer than wide, female as long as wide. Abdomen: Male tergite IV with pair of transverse patches of microtrichia reaching middle, patches absent in female. Aedeagus: Median lobe of genitalia divided vertically, upper lobe narrow apically (Fig. 66l). Phallobase of median lobe symmetrical and rounded (Fig. 66l). Parameres symmetrical broader than median lobe, with setae apically (Fig. 66l).

Distribution. Central Otago, Mid Canterbury, Mackenzie (Fig. 67: white squares).
