Very similar in colour to Chromodoris lochi and Chromodoris willani in having a bluish white body with longitudinal black lines, and pale gills and rhinophores. The three species can be distinguished externally as follows:
C. lochi: Gills and rhinophore clubs uniformly straw coloured or yellowish.
C. willani: Gills and rhinophore clubs translucent clear or bluish, with white specks
C. boucheti: Rhinophore clubs uniformly yellow. Gills - lower half white, upper half yellow, a black line runs from the base, up both the inside and outside edge of each gill, for a varying distance.

Originally described from the Comoro Islands and reported from the Maldives (Debelius, 1996). It is reported below from South Africa.
