This species can be distinguished from other species by the following combination of characters: body length 2.3–2.6 mm ; ventral surface of male head distinctly convex with heart-shaped depression containing pair of diagonal processes; eye large and prominent, approximately two-thirds length of temple; shape of antennomeres and genitalia unique to species. Redescription. Length 2.3–2.6 mm . Body reddish brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 35a ). Head: Round, widest across eyes ( Fig. 35c ). Ventral surface of male head distinctly convex with heart-shaped depression containing pair of diagonal processes ( Fig. 35d ). Antennomere 1 approximately 1.5 times longer than wide, 2 longer than wide, 3–8 subquadrate, 9–10 weakly transverse. Frontal sulcus deep, reaching midpoint of eye ( Fig. 35c ). Anterior frontal fovea round ( Fig. 35c ), posterior frontal fovea oval ( Fig. 35c ). Eye large and prominent, approximately two-thirds length of temple ( Fig. 35c ). Thorax: Prosternum as long as wide, widest at midpoint. Elytra rectangular ( Fig. 35a ). Meso-and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle. Aedeagus: Median lobe simple and small, < 0.25 mm ( Fig. 35b ). Phallobase of median lobe symmetrical and rounded ( Fig. 35b ). Parameres symmetrical with setae apically ( Fig. 35b ). Type Locality. New Zealand (specific locality unknown) . Distribution. Buller, Coromandel, Dunedin, Gisborne , Fiordland, Marlborough , North Canterbury , Nelson , Otago Lakes, Marlborough Sounds, Stewart Island, Southland , Westland, Wairarapa, Wellington ( Fig. 36 : black squares). Habitat. Most specimens of this species were collected using window and flight intercept traps, by fogging, or by sifting mossy leaf or decayed log litter in Nothofagus , podocarp, hardwood, or broadleaf forests. Comments. The original description cited two male and one female specimens, but we were only able to find and examine one female . Nevertheless, specimens of S. sharpi can be distinguished from those of other species by the shape and size of the antennomeres, frontal foveae, frontal sulcus, and size of the eye. The type specimens of S. clavatella , S. grata , and S. posticalis share these diagnostic characters. For these reasons, we have placed S. clavatella , S. grata , and S. posticalis in synonymy with S. sharpi .
