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 3.5–4.1 mm . Body brown, antennae, legs, and maxillary palpi paler, elytra yellowish brown ( Fig. 19a ). Head: Transverse, widest across temples ( Fig. 19a ). Antennomere 1 approximately 2.5 times longer than wide, 2–3 longer than wide, 4–5 elongate, 6–8 longer than wide, 9–10 subquadrate. Frontal sulcus deep and wide, reaching midpoint of eye from frontal fovea. Anterior frontal fovea extremely small. Posterior frontal fovea round. Eye small and prominent, one-third length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra approximately triangular ( Fig. 19a ). Meso-and metathorax trapezoidal, as long as wide. Aedeagus: Median lobe longer than parameres ( Fig. 19e ). Phallobase of median lobe symmetrical and rectangular ( Fig. 19e ). Parameres asymmetrical, right paramere broader and with slender branch apically ( Fig. 19e ). Type Locality. Tairua , New Zealand . Distribution. A u c k l a n d, B a y o f P l e n t y, Coromandel, Waikato ( Fig. 20 : black circles). Habitat. Most specimens of this species were collected using pitfall traps or by sifting leaf litter or rotten wood in kauri or broadleaf forests. One specimen was collected with ants of the genus Mesoponera Emery. Comments. Specimens of S. pulchra are difficult to distinguish from those of other species externally, but the shape and size of the antennomeres and genitalia are diagnostic. The type specimens of S. robusta share these diagnostic characters, and this species has been collected at or near the type locality. For these reasons, we have placed S. robusta in synonymy with S. pulchra .
