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 View FIGURE 2 b); male head swollen ventrally ( Fig. 2 View FIGURE 2 m); antennomeres 4–5 longer than wide, 6–10 subquadrate; median lobe as long as paramere, one-half width of parameres ( Fig. 3 View FIGURE 3 b).

Redescription. Length 1.7–2.0 mm. Body brown, elytra, legs, antenna and maxillary palpi paler ( Fig. 1 View FIGURE 1 b). Head. Male head blunt triangular, widest across temples ( Fig. 1 View FIGURE 1 b), swollen ventrally ( Fig. 2 View FIGURE 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 View FIGURE 2 b). Anterior frontal fovea small and round. Posterior frontal fovea elongate. Eye large and prominent, one-half length of temple ( Fig. 2 View FIGURE 2 b). Thorax. Prosternum as long as wide, widest at one-third length. Elytra rectangular ( Fig. 1 View FIGURE 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 View FIGURE 3 b). Phallobase symmetrical and rounded ( Fig. 3 View FIGURE 3 b). Parameres symmetrical, elongate triangular with setae at tip ( Fig. 3 View FIGURE 3 b).

Type locality. Tairua (CL), New Zealand.

Distribution. Auckland (AK), Coromandel (CL) ( Fig. 4 View FIGURE 4 : triangles).

Habitat. Most specimens of this species were collected using window, flight intercept, and pitfall traps, or by sifting leaf and log litter in kauri, hardwood, and podocarp forests. One specimen was collected from moss.
