Diagnosis. This species can be distinguished from the other species of the insignis species-group by the following combination of characters: body length 2.4–2.8 mm; temporal lobe of male head distinctly projecting, exceeding eye, with weakly concave ventral surface; male temporal lobe with L-shaped depression anteriorly; ventral surface of male head with transverse process behind mouthparts with depression medially and setae along edge; elytra subquadrate; shape of antennomeres and genitalia unique to species.

Redescription. Length 2.4–2.8 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 68b View Fig ). Head: Male head triangular, widest across temples ( Fig. 69b View Fig ). Female head bluntly triangular, widest across eyes. Antennomere 1 approximately 1.5 times longer than wide, 2–3 subquadrate, 4–7 longer than wide, 8–10 subquadrate. Frontal sulcus deep, reaching end of eye. Anterior frontal fovea round, partially covered by frontal rostrum, posterior frontal fovea round. Male eye prominent, approximately one-fourth length of temple, female slightly smaller. Temporal lobe of male head distinctly projecting, exceeding eye, with weakly concave ventral surface ( Fig. 69b View Fig ). Male temporal lobe with L-shaped depression anteriorly ( Fig. 69b View Fig ). Ventral surface of male head with transverse process behind mouthparts with depression medially, with setae along edge ( Fig. 69b View Fig ). Thorax: Prosternum as long as wide, widest at one-third length. Elytra subquadrate ( Fig. 68b View Fig ). Meso- and metathorax trapezoidal, as long as wide. Abdomen: Tergite IV without patches of microtrichia. Aedeagus: Median lobe of genitalia broad with triangular head ( Fig. 70b View Fig ). Phallobase of median lobe symmetrical and rounded ( Fig. 70b View Fig ). Parameres symmetrical and triangular, setose from midpoints to apices ( Fig. 70b View Fig ).

Type Locality. Belgrove , near Nelson, New Zealand .

Distribution. Nelson ( Fig. 71 View Fig : triangles).

Habitat. One specimen was collected by sifting leaf litter.

Comments. Specimens of S. hectorii can be distinguished from those of other species by the shape of the ventral surface of the male head and the antennomeres. The type specimen of S. distorta shares these diagnostic characters. For these reasons, we have placed S. distorta in synonymy with S. hectorii .
