Diagnosis. This species is similar in appearance to other members of this species-group but can be distinguished by the shape of the antennae and genitalia.

Redescription. Length 2.6–2.9 mm. Body brown, antennae, legs, and maxillary palpi paler, elytra yellowish brown ( Fig. 25b ). Head: Transverse, widest across temples ( Fig. 25g ). Antennomere 2 longer than wide, 3–10 subquadrate, 5–6 weakly enlarged. Eye small and prominent, one-third length of temple. Thorax: Prosternum weakly transverse, widest at midpoint. Elytra rectangular ( Fig. 25b ). Meso- and metathorax trapezoidal, as long as wide. Aedeagus: Median lobe slender, much shorter than parameres ( Fig. 25e ). Phallobase of median lobe asymmetrical and rectangular ( Fig. 25e ). Parameres asymmetrical, left longer than right with dense setae along mid line except apex ( Fig. 25e ). Right paramere with dense setae along midline ( Fig. 25e ).

Type Locality. Tairua , Coromandel, New Zealand .

Distribution. Auckland, Coromandel, Northland, Taupo ( Fig. 26 : triangles).

Habitat. Specimens of this species were collected by sifting leaf and log litter in podocarp and broadleaf forests.
