Diagnosis. This species can be distinguished from the other species of the auripila speciesgroup by the following combination of characters: larger body, length 2.1–2.3 mm; weakly enlarged male antennomeres 5–10; frontal sulcus linear and deep, extending slightly posterior to eye; male hind femur with triangular process at middle of c) S. chathamensis , d) S. pittensis , e) S. chandleri , f) S. threekingsensis , g) S. gimmeli , h) S. sokolovi . Scale bars = 1 mm. mesal margin; shape of antennomeres and genitalia unique to species.

Redescription. Length 2.1–2.3 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 37a ). Head: Round, widest across eyes ( Fig. 37a ). Male antennomere 1 approximately 1.5 times longer than wide, 2–10 subquadrate, 5–10 weakly enlarged. Female antennomere 2 longer than wide, 3 subquadrate, 4–5 longer than wide, 6–10 subquadrate. Frontal sulcus linear and deep, slightly exceeding eye. Anterior frontal fovea oval, posterior frontal fovea elongate. Eye large and prominent, approximately one-half length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra approximately triangular ( Fig. 37a ). Meso- and metathorax trapezoidal, as long as wide. Male hind femur with triangular process at middle of mesal margin. Aedeagus: Lateral median lobe rectangular and apical lobe weakly emarginate ( Fig. 38a ). Phallobase of median lobe symmetrical and rectangular ( Fig. 38a ). Parameres symmetrical and curved to C-shaped with setae apically and 1 seta at middle ( Fig. 38a ).

Type Locality. Erua , Taupo, New Zealand .

Distribution. Gisborne, Taupo, Waikato ( Fig. 39 : black circles).

Habitat. Most specimens of this species were collected using flight intercept traps or by sifting leaf litter in broadleaf or podocarp forests.
