Diagnosis. This species can be distinguished from the other species of the auripila speciesgroup by the following combination of characters: body length 2.1–2.3 mm; male antennomeres 5–10 enlarged; frontal sulcus deep and wide, reaching vertexal fovea; posterior frontal fovea large and oval; shape of antennomeres and genitalia unique to species.

Redescription. Length 2.1–2.3 mm. Body reddish brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 37b View Fig ). Head: Round, widest across eyes ( Fig. 37j View Fig ). Antennomere 1 approximately 1.5 times longer than wide, 2 longer than wide, 3–10 subquadrate, male 5–10 enlarged. Frontal sulcus deep and wide, reaching vertexal fovea. Anterior frontal fovea round, posterior frontal fovea large oval. Eye large and prominent, approximately one-half length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra approximately triangular ( Fig. 37b View Fig ). Meso-and metathorax trapezoidal as long as wide. Aedeagus: Median lobe slender ( Fig. 38b View Fig ). Phallobase of median lobe symmetrical and rectangular ( Fig. 38b View Fig ). Parameres symmetrical and curved to C-shaped with setae apically and 1 seta at middle ( Fig. 38b View Fig ).

Type Locality. Picton , Marlborough Sounds, New Zealand .

Distribution. Buller, Fiordland, Nelson, Mid Canterbury, Marlborough Sounds, Westland, Wellington ( Fig. 39 View Fig : triangles).

Habitat. Specimens of this species were collected by fogging or sifting leaf or decayed log litter in podocarp or Nothofagus forests.

Comments. Specimens of S. spiniventris can be distinguished from other species by the enlarged male antennomeres 5–10; deep and wide frontal sulcus reaching a point even with the vertexal fovea; posterior frontal fovea large and oval; and the shape of the antennomeres and genitalia. The type specimens of S. occipitalis share these diagnostic characters. For these reasons, we have placed S. occipitalis in synonymy with S. spiniventris .
