Diagnosis. This species can be distinguished from the other species of the anisarthra speciesgroup by the following combination of characters: larger body, length 2.4–2.8 mm; male antennomeres 4–6 enlarged and 4–11 bearing tubercles; frontal sulcus deep reaching midpoint of eye; anterior frontal fovea round and partially covered by frontal rostrum, posterior frontal fovea oval; eye large and prominent, approximately twothirds length of temple; shape of genitalia unique to species.

Redescription. Length 2.4–2.8 mm. Body reddish brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 45a View Fig ). Head: Bluntly triangular, widest across eyes ( Fig. 45l View Fig ). Ventral surface of head weakly convex. Male antennomere 1 approximately 2 times longer than wide, 2–10 subquadrate, 4–6 enlarged, 7–10 bearing tubercles. Female antennomeres 2–3 subquadrate, 4–5 longer than wide, 6–10 subquadrate, 4–11 bearing tubercles. Frontal sulcus deep, reaching midpoint of eye. Anterior frontal fovea round and partially covered by frontal rostrum ( Fig. 45l View Fig ), posterior frontal fovea oval ( Fig. 45l View Fig ). Eye large and prominent, approximately one-half length of temple ( Fig. 45l View Fig ). Thorax: Prosternum as long as wide, widest at midpoint. Elytra rectangular ( Fig. 45a View Fig ). Hind wings well-developed. Meso- and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle. Aedeagus: Median lobe as long and wide as parameres ( Fig. 45f View Fig ). Phallobase of median lobe symmetrical and rounded ( Fig. 45f View Fig ). Parameres symmetrical with setae apically ( Fig. 45f View Fig ).

Type Locality. Moeraki , Dunedin, New Zealand .

Distribution. Dunedin, Fiordland, Mid Canterbury, Otago Lakes, Southland ( Fig. 46 View Fig : black circles).

Habitat. Most specimens of this species were collected by sifting mossy leaf or log litter in forests or the intertidal zone of beach areas.

Comments. Specimens of S. anisarthra can be distinguished from other species by the enlarged male antennomeres 4–6 and dorsal shape of head. The type specimens of S. dickensis and S. suturalis share these diagnostic characters, and additionally those species have been collected at or near the type localities. For these reasons, we have placed S. dickensis and S. suturalis in synonymy with S. anisarthra .
