Diagnosis. This species can be distinguished from the other species of this species-group by the following combination of characters: larger body, length 2.6–2.8 mm; ventral surface of male head convex with setose gular region; eye large and prominent, approximately one-half length of temple; frontal sulcus deep and reverse keyholeshaped; shape of antennomeres and genitalia unique to species.

Redescription. Length 2.6–2.8 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 31a View Fig ). Head: Head round, widest across eyes ( Fig. 31a View Fig ). Ventral surface of male head convex with setose gular region. Male antennomere 1 approximately 2 times longer than wide, 2 subquadrate, 3–8 longer than wide, 9–10 subquadrate. Female antennomere longer than male, 2–3 subquadrate, 4–7 longer than wide, 8–10 subquadrate. Frontal sulcus deep, reaching posterior end of 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 rectangular ( Fig. 31a View Fig ). Meso- and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle, less developed in female. Aedeagus: Median lobe divided, minor lobe longer with tubercles ( Fig. 31e View Fig ). Phallobase of median lobe symmetrical and rounded ( Fig. 31e View Fig ). Parameres symmetrical with sparse setae from apex to midpoint, broader than median lobe ( Fig. 31e View Fig ).

Type Locality. Rakaia Gorge , Mid Canterbury, New Zealand .

Distribution. Fiordland, Mid Canterbury, Otago Lakes, Westland ( Fig. 32 View Fig : black circles).

Habitat. Most specimens of this species were collected by fogging or sifting mossy leaf or log litter in Nothofagus forests.

Comments. Specimens of S. rustica can be distinguished from other species by the shape and size of the antennomeres, frontal fovea, frontal sulcus, size of eye, and unique genitalia. The type specimens of S. brevifossa and S. subcuneata share these diagnostic characters, and these species have been collected at or near the type locality of S. rustica . For these reasons, we have placed S. brevifossa and S. subcuneata in synonymy with S. rustica .
