This species can be distinguished from the other species of the arboricola speciesgroup by the following combination of characters: larger body length, 2.5–3.0 mm; ventral surface of male head with blunt process bearing dense setae behind mouthparts; male antennomeres 2–10 subquadrate and weakly enlarged; shape of genitalia unique to species. Redescription. Length 2.5–3.0 mm. Body reddish brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 41b ). Head: Bluntly triangular, widest across eyes ( Fig. 41b ). Ventral surface of male head with blunt process bearing dense setae behind mouthparts. Male antennomere 1 approximately 1.5 times longer than wide, 2–10 subquadrate and weakly enlarged. Female antennomeres 2–3 subquadrate, 4–5 longer than wide, 6–10 subquadrate. Frontal sulcus deep, reaching one-third length of eye. Anterior frontal fovea oval, posterior frontal fovea round. Eye large and prominent, approximately as long as temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra rectangular ( Fig. 41b ). Mesoand metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle, less developed in female. Aedeagus: Median lobe triangular, dorsal process crescent-shaped ( Fig. 41d ). Phallobase of median lobe symmetrical and rectangular ( Fig. 41d ). Parameres symmetrical and rectangular with sparse setae anteriorly and posteriorly ( Fig. 41d ). Type Locality. Moa Basin , Mid Canterbury , New Zealand . Distribution. Fiordland, Mid Canterbury , Mackenzie, Nelson , Westland ( Fig. 42 : triangles). Habitat. Most specimens of this species were collected by sifting mossy leaf or log litter in Nothofagus forests. Many specimens were collected at high elevations.
