Chaceon bicolor is a species of crab. Chaceon bicolor differs from all species of the genus in color pattern with the anterior part of the body purplish rather than reddish. In addition to color pattern C. bicolor also differs from C. granulatus in having compressed rather than depressed dactyli on the walking legs; also the hepatic region of the carapace in C. granulatus is coarsely granular whereas it is smooth in C. bicolor.
