Nine species of the genus Dischissus were reported from the Palaearctic region (Baehr, 2003) and most species are distributed in China and Japan. Among them, Dischissus mirandus Bates, 1873 was the only species reported in Korea up to now (ESK and KSAE, 1994; Park and Paik, 2001). 

Genus Dischissus is easily distinguished by dense setae of whole body, globular shape and deep punctuation of pronotum and two pairs of yellowish or yellow-reddish large spot of elytra.
