Hypselodoris villafranca (Risso, 1818) is another dark blue chromodorid species with several dorsal yellow or white lines, but generally they form an irregular pattern, something like a broken network. In some small adults of H. villafranca, there may be three parallel lines as in H. picta, but this species is easily distinguished from H. picta by the greyish coloration of the gill and rhinophores and the presence of a white line on the rhinophores. Also, in H. villafranca the dorsal yellow lines form a circle around the branchial sheath.
