Chromodoris boucheti can reach a length of 30-50 mm. The upper surface of the body is bluish white, with longitudinal black lines and yellow rhinophores. The lower half of the gills is white, the upper half is yellow. Moreover this species shows characteristic black markings running up from the base on the inside and outside edge of its gills.
