Etymology. This species is named for one of the enthusiastic supporters of this study and world staphylinid specialist, Kee-Jeong Ahn.

Diagnosis. This species is similar in appearance to other members of this species-group but can be distinguished by the shape of the antennae and genitalia.

Description. Length 3.2–3.5 mm. Body brown, antennae, legs, and maxillary palpi paler, elytra yellowish brown ( Fig. 19b ). Head: Transverse, widest across temples ( Fig. 19i ). Antennomere 1 approximately 2.5 times longer than wide, 2–3 longer than wide, 4–5 elongate, 6–8 longer than wide, 9–10 subquadrate. Frontal sulcus deep and wide, reaching midpoint of eye from frontal fovea ( Fig. 19i ). Anterior frontal fovea extremely small ( Fig. 19i ). Posterior frontal fovea round ( Fig. 19i ). Eye small and prominent, one-third length of temple ( Fig. 19i ). Thorax: Prosternum as long as wide, widest at midpoint. Elytra approximately triangular ( Fig. 19b ). Meso- and metathorax trapezoidal, as long as wide. Aedeagus: Apical lobe of genitalia U-shaped ( Fig. 19f ). Phallobase of median lobe symmetrical and rectangular ( Fig. 19f ). Parameres asymmetrical, right paramere with 3 branches, 2 from base, 1 apically ( Fig. 19f ).
