Etymology. This species is named for Kee-Jeong Ahn lab alumnus, chrysomelid beetle specialist, and an enthusiastic supporter of this study, Mr. Choru Shin.
Diagnosis. This species can be distinguished from the other species of Brounea by the following combination of characters: small body, length 1.2–1.4 mm; eye small, one-third length of temple (Fig. 2 d); male head weakly swollen ventrally (Fig. 2 o); antennomeres 3–8 subquadrate, 9–10 weakly transverse; median lobe longer than parameres with acute apical lobe (Fig. 3 d).
Description of male. Length 1.2–1.4 mm. Body yellowish brown, elytra, legs, antennae and maxillary palpi paler (Fig. 1 d). Head. Head bluntly triangular, widest across temples (Fig. 2 d), weakly swollen ventrally (Fig. 2 o). Antennomeres 1–2 elongate, 3–10 subquadrate, 9–10 weakly transverse. Frontal sulcus shallow, reaching to midpoint of eye from apex of rostrum (Fig. 2 d). Anterior and posterior frontal fovea small and round. Eye small, onethird length of temple. Thorax. Prosternum longer than wide, widest at one-third length. Elytra rectangular (Fig. 1 d). Hind wings well-developed. Meso- and metaventrites together trapezoidal in ventral view, longer than wide. Abdomen. Abdominal tergite IV with pair of transverse patches of microtrichia. Aedeagus. Median lobe longer than parameres with acute apical lobe (Fig. 3 d). Phallobase symmetrical and rounded (Fig. 3 d). Parameres symmetrical with setae at tip, weakly narrower at distal one-third (Fig. 3 d). Female unknown.
Distribution. Northland (ND) (Fig. 4: star). Habitat. Specimens of this species were collected by sifting decaying log litter.
