 Description. Body length 2.5–3.4 mm. Body glossy. Color usually black, legs dark brown, base of elytral suture red (Fig. 1).   
 Head. As long as wide. Eyes large, convex, occupying almost entire lateral side of head. Mandible more or less blunt, three subapical teeth present. Median sclerotized plate of hologlossa (Fig. 5) oval, about 1.4 times longer than wide. In male antenna slightly longer than female. Male antenna (Fig. 9): scape robust, about 3.1 times longer than wide; pedicel about 2.1 times longer than wide, shorter and narrower than scape; antennomere 3 slender, slightly dilated apically, about 1.6 times longer than wide; 4–7 longer than wide; 8–9 about 1.1 times longer than wide; 10 about 1.1 times wider than long. Female antenna (Fig. 10): antennomeres 8–9 about 1.1 times wider than long; 10 about 1.2 times wider than long.   
 Thorax: Pronotum (Fig. 17) wider than long, widest at anterior third, narrowest at base. Intervals between punctures slightly narrower than puncture diameter. Scutellar impression (Fig. 21) 1.3 times longer than wide, shaped as broadly emarginated inverted triangle, with moderate pubescence. Elytra slightly wider than pronotum, each elytron with deep diagonal groove in apical third.

 Abdomen: Male sternite VIII (Fig. 25) wider than long and slightly prolonged apically. Posterior margin of female sternite VIII (Fig. 29) broadly round.   
Aedeagus (Figs. 33, 37) oval, parameres broad, wrapping around the middle of median lobe.  
Spermatheca (Fig. 41) in the middle curved about 90 degrees.

Park & D.-H. Lee, ex under stones near stream.   
 Distribution. Korea, Japan, and China   
 Remarks. This species can be easily distinguished from other Korean Thinodromus by the red mark at the base of elytral suture, more shining body, and proportion of each antennomere. The lectotype is female and brown without red mark at the apical region of elytral suture. However, all Korean specimens we studied are with red mark. First description of males is presented and this species is new to Korea.
