Diagnosis. This species can be distinguished from the other species of the insignis speciesgroup by the following combination of characters: body length 2.5–2.8 mm; temporal lobe of male head weakly projecting, as long as eye with flattened ventral surface; ventral surface of male head with setose triangular process behind mouthparts; male elytra rectangular, female elytra subquadrate; shape of antennomeres and genitalia unique to species.
Redescription. Length 2.5–2.8 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler (Fig. 68c). Head: Head bluntly triangular, widest across eyes (Fig. 69c). Antennomere 1 approximately 1.5 times longer than wide, 2–6 longer than wide, 7–10 subquadrate. Frontal sulcus deep, reaching midpoint of eye (Fig. 70y). Anterior frontal fovea round, partially covered by frontal rostrum, posterior frontal fovea round (Fig. 70y). Eye large and prominent, approximately one-half length of temple (Fig. 69c). Temporal lobe of male head weakly projecting, as long as eye with flattened ventral surface (Fig. 69c). Ventral surface of male head with setose triangular process behind mouthparts (Fig. 69c). Thorax: Prosternum as long as wide, widest at one-third length. Male elytra rectangular (Fig. 68c), female elytra subquadrate. Male meso- and metathorax trapezoidal, longer than wide, female as long as wide. Abdomen: Male tergite IV with pair of transverse patches of microtrichia reaching middle, patches absent in female. Aedeagus: Median lobe of genitalia broad with pair of small, triangular processes at one-third length (Fig. 70c). Phallobase of median lobe symmetrical and rounded (Fig. 70c). Parameres symmetrical and slender with setae apically and 1 seta at middle (Fig. 70c).
Type Locality. Near Whangarei Harbour, Northland, New Zealand.
Distribution. Auckland, Buller, Northland, Mid Canterbury (Fig. 71: black squares).
Habitat. Specimens of this species were collected using pitfall, yellow pan, flight intercept, and window traps or by sifting leaf and wood litter.
Comments. Specimens of S. bipunctata can be distinguished from those of other species by the shape of the ventral surface of the male head and the antennomeres. The type specimens of S. brevisternis, S. confusa, S. frontalis, S. fulva, S. halli, S. immota, S. laetula, S. laminata, S. latula, S. lawsoni, and S. osculans share these diagnostic characters, and additional specimens have been collected at or near the type locality. For these reasons, we have placed S. brevisternis, S. confusa, S. frontalis, S. fulva, S. halli, S. immota, S. laetula, S. laminata, S. latula, S. lawsoni, and S. osculans in synonymy with S. bipunctata.
