Diagnosis. This species can be distinguished from the other species of the anisarthra speciesgroup by the following combination of characters: body length 2.3–2.7 mm; antennomeres 4–11 bearing tubercles; frontal sulcus shallow, reaching midpoint of eye; anterior frontal fovea round partially covered by frontal rostrum, posterior frontal fovea oval; eye large and prominent, one-half length of temple; shape of antennomeres and genitalia unique to species.
Redescription. Length 2.3–2.7 mm. Body reddish brown, antennae, maxillary palpi, elytra, and legs paler (Fig. 45b). Head: Male head round, widest across eyes (Fig. 45b). Male antennomere 1 approximately 2 times longer than wide, 2–10 subquadrate, 4–11 bearing tubercles. Female antennomeres 2–3 subquadrate, 4 longer than wide, 5–7 subquadrate, 8–10 weakly transverse, 4–11 bearing tubercles. Frontal sulcus shallow, reaching midpoint of eye. Anterior frontal fovea round partially covered by frontal rostrum, posterior frontal fovea oval. Eye large and prominent, one-half of temple. Thorax: Prosternum as long as wide, widest at one-third. Elytra rectangular (Fig. 45b), female slightly shorter. Meso-and metathorax trapezoidal, longer than wide. Abdomen: Male tergite IV with pair of oval or transverse weak patches of microtrichia, patches absent in female. Aedeagus: Median lobe elongate and bent to right (Fig. 45g –h). Phallobase of median lobe symmetrical and rounded (Fig. 45g –h). Parameres symmetrical and long with setae apically (Fig. 45g –h).
Type Locality. Mount Oakden, Mid Canterbury, New Zealand.
Distribution. Buller, Fiordland, Marlborough, Mid Canterbury, Mackenzie, Nelson, Otago Lakes (Fig. 46: triangles).
Habitat. Most specimens of this species were collected by sifting leaf and moss litter.
Comments. We could not examine any of the syntypes of S. planipennis because they are apparently missing from the collection at the Natural History Museum, London. We based our concept of this species on two specimens from the type locality that were identified by T. Broun, who described this species, as S. planipennis.
