Etymology. This species is named in memoriam after Mr. Seong-Mo Choi. He was the first author' best friend, an alumnus of Kee-Jeong Ahn’s lab, and an enthusiastic supporter of this study. He passed away as a result of a heartbreaking drowning accident during summer 2008.

Diagnosis. This species can be distinguished from the other species of Brounea by the following combination of characters: large eye, one-half length of temple ( Fig. 2 View FIGURE 2 g); male gula with triangular depression bearing dense setae ( Fig. 2 View FIGURE 2 r: arrow); male abdominal sternite VI with setose round depression at middle ( Fig. 3 View FIGURE 3 q: arrow); antennomeres 4–7 longer than wide, 8–10 subquadrate; median lobe triangular, as wide as parameres ( Fig. 3 View FIGURE 3 g).

Description. Length 1.6–1.8 mm. Body brown, elytra, legs, antennae and maxillary palpi paler ( Fig. 1 View FIGURE 1 g). Head. Head triangular, widest across temples ( Figs. 2 View FIGURE 2 g, 3m). Male gula with triangular depression bearing dense setae ( Fig. 2 View FIGURE 2 r: arrow). Female head unmodified. Antennomeres 1–2 elongate, 3 subquadrate, 4–7 longer than wide, 8–10 subquadrate. Frontal sulcus deep and reaching to one-third length of eye from apex of rostrum ( Figs. 2 View FIGURE 2 g, 3m). Posterior frontal fovea oval ( Fig. 3 View FIGURE 3 m). Eye large and prominent, one-half length of temple ( Figs. 2 View FIGURE 2 g, 3m). Thorax. Prosternum as long as wide, widest one-third length. Elytra rectangular ( Fig. 1 View FIGURE 1 g). Hind wings of both sexes welldeveloped. Meso- and metaventrites together trapezoidal in ventral view, longer than wide. Abdomen. Abdominal tergite IV with pair of oval or transverse patches of microtrichia. Male abdominal sternite VI with setose round depression at middle ( Fig. 3 View FIGURE 3 q: arrow). Female sternite unmodified. Aedeagus. Median lobe triangular, as wide as parameres ( Fig. 3 View FIGURE 3 g). Phallobase symmetrical and rounded ( Fig. 3 View FIGURE 3 g). Parameres blunt and symmetrical with setae at tip ( Fig. 3 View FIGURE 3 g).

Distribution. Auckland (AK), Coromandel (CL), Northland (ND) ( Fig. 5 View FIGURE 5 : triangles).

Habitat. Most specimens of this species were collected using flight intercept or window traps, or by sifting litter in broadleaf, hardwood, kauri, or podocarp forests.
