Etymology. This species is named for Kee-Jeong Ahn lab alumna, seashore staphylinid specialist, and an enthusiastic supporter of this study, Dr. Mi-Jeong Jeon.

Diagnosis. This species can be distinguished from the other species of Brounea by the following combination of characters: eye large, two-thirds length of temple (Fig. 2 f); male head weakly swollen ventrally, gular depression bearing dense setae (Fig. 2 q: arrow); antennomeres 4–8 longer than wide, 9–10 subquadrate; median lobe bullet shaped, as long as parameres (Fig. 3 f).

Description. Length 1.9–2.1 mm. Body brown, elytra, legs, antennae and maxillary palpi paler (Fig. 1 f). Head. Head bluntly triangular, widest across temples (Fig. 2 f). Male head weakly swollen ventrally, gular depression bearing dense setae (Fig. 2 q: arrow). Female head unmodified. Antennomeres 1–2 elongate, 3 subquadrate, 4–8 longer than wide, 9–10 subquadrate. Frontal sulcus shallow and reaching one-third length of eye from apex of rostrum (Fig. 2 f). Anterior frontal fovea small and round, partially covered by frontal rostrum. Posterior frontal fovea small and round. Eye large and prominent, two-thirds length of temple (Fig. 2 f). Thorax. Prosternum as long as wide, widest at midpoint. Elytra rectangular (Fig. 1 f). Hind wings of both sexes well-developed. Meso- and metaventrites together trapezoidal in ventral view, longer than wide. Abdomen. Abdominal tergite IV with pair of transverse patches of microtrichia reaching middle. Aedeagus. Median lobe bullet shaped, as long as parameres (Fig. 3 f). Phallobase symmetrical and rounded (Fig. 3 f). Parameres symmetrical, elongate triangular with thick setae at tip (Fig. 3 f).

Distribution. Auckland (AK), Coromandel (CL), Northland (ND) (Fig. 5: black circles).

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