Diagnosis. This species can be distinguished from the other species of Brounea by the following combination of characters: eye large, one-half length of temple (Fig. 2 b); male head swollen ventrally (Fig. 2 m); antennomeres 4–5 longer than wide, 6–10 subquadrate; median lobe as long as paramere, one-half width of parameres (Fig. 3 b).
Redescription. Length 1.7–2.0 mm. Body brown, elytra, legs, antenna and maxillary palpi paler (Fig. 1 b). Head. Male head blunt triangular, widest across temples (Fig. 1 b), swollen ventrally (Fig. 2 m). Female head unmodified. Antennomeres 1–2 elongate, 3 subquadrate, 4–5 longer than wide, 6–10 subquadrate. Frontal sulcus deep, reaching to mid-point of eye from apex of rostrum (Fig. 2 b). Anterior frontal fovea small and round. Posterior frontal fovea elongate. Eye large and prominent, one-half length of temple (Fig. 2 b). Thorax. Prosternum as long as wide, widest at one-third length. Elytra rectangular (Fig. 1 b). Hind wings of both sexes well-developed. Meso- and metaventrites together trapezoidal in ventral view, longer than wide. Abdomen. Abdominal tergite IV with a pair of transverse patches of microtrichia reaching middle. Aedeagus. Median lobe as long as paramere, onehalf width of parameres (Fig. 3 b). Phallobase symmetrical and rounded (Fig. 3 b). Parameres symmetrical, elongate triangular with setae at tip (Fig. 3 b).
Type locality. Tairua (CL), New Zealand.
Distribution. Auckland (AK), Coromandel (CL) (Fig. 4: triangles).
