Diagnosis. This species can be distinguished from the other species of Brounea by the following combination of characters: larger body, length 2.1–2.4 mm; eye large, two-thirds length of temple (Fig. 3 l); frontal sulcus deep and inverted keyhole-shaped (Figs. 2 a: arrow, 3l); antennomeres 4–5 longer than wide, 6–10 subquadrate; median lobe long with tuberculate apical lobe (Fig. 3 a); paramere broader than median lobe, emarginate in distal one-third (Fig. 3 a).
Redescription. Length 2.1–2.4 mm. Body reddish brown, elytra, legs, antennae and maxillary palpi paler (Fig. 1 a). Head. Head round, widest across eyes (Figs. 2 a, 3l). Ventral surface of head of both sexes unmodified (Fig. 2 l); lacking swollen ventral surface or dense gular setae. Male antennomeres 1–2 elongate, 3 subquadrate, 4–5 longer than wide, 6–10 subquadrate, 9–11 weakly transverse. Frontal sulcus inverted keyhole-shaped (Figs. 2 a: arrow, 3l). Anterior frontal fovea absent. Posterior frontal fovea present and oval (Fig. 3 l). Eye large and prominent, approximately two-thirds length of temple (Fig. 3 l). Thorax. Prosternum as long as wide, widest at midpoint. Elytra rectangular (Fig. 1 a). Hind wings 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 long with tuberculate apical lobe (Fig. 3 a). Phallobase symmetrical and rounded (Fig. 3 a). Parameres symmetrical with setae at tip, broader than median lobe, emarginate in distal one-third (Fig. 3 a).
Type locality. Erua (TO), New Zealand.
Distribution. Auckland (AK), Bay of Plenty (BP), Coromandel (CL), Gisborne (GB), Northland (ND), Taupo (TO), Waikato (WO) (Fig. 4: black circles).
Habitat. Most specimens of this species were collected using window, flight intercept, and malaise traps, or by sifting leaf and log litter in kauri, broadleaf, hardwood, and podocarp forests.
