Diagnosis. This species can be distinguished from S. denticollis by the bluntly triangular head, larger eye, enlarged male antennomeres 5–6 lacking distinctive tubercles, and unique shape of the genitalia.

Redescription. Length 2.3–3.8 mm. Body brown, antennae, legs, and maxillary palpi paler, elytra yellowish brown ( Fig. 21a ). Head: Bluntly triangular with prominent frontal rostrum ( Fig. 21f ). Male antennomeres 2–10 subquadrate, 5–6 enlarged, 5 largest. Female antennomeres 2–3 subquadrate, 4–5 longer than wide, 6–10 subquadrate. Frontal sulcus shallow, reaching midpoint of eye from frontal fovea. Anterior frontal fovea oval, open anteriorly, posterior frontal fovea round. Eye large and prominent, approximately one-half length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra subquadrate ( Fig. 21a ). Meso- and metathorax trapezoidal, as long as wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle. Aedeagus: Median lobe with minor lobe bearing from base ( Fig. 21c ). Phallobase of median lobe asymmetrical and rounded ( Fig. 21c ). Parameres asymmetrical, left paramere longer than right with 2 slender branches apically ( Fig. 21c ).

Type Locality. New Zealand (unknown specific locality) .

Distribution. A u c k l a n d, B a y o f P l e n t y, Coromandel, Northland, Taranaki, Wellington ( Fig. 22 : black circles).

Habitat. Most specimens of this species were collected using yellow pan and Malaise traps or were taken by sifting leaf litter or rotten wood in hardwood or podocarp forests. Some specimens were collected with Mesoponera ants, and one specimen was collected from a carrion bait trap.

Comments. Specimens of S. parva are easy to distinguish from other species externally by the enlarged male antennomeres 5–6; large eye that is approximately one-half length of temple; prominent frontal rostrum; shallow frontal sulcus; oval and anteriorly open anterior frontal fovea. The type specimens of S. brevicornis , S. concolorata , S. fovealis , S. insolens , S. punctata , S. rectipes , and S. rotundiceps share these diagnostic characters. For these reasons, we have placed these species in synonymy with S. parva .
