- The authors have visually examined specimens in these genera for external pigment patches associated with the sensory structure described. Genera that have been suggested as members of Chitonida (Sirenko, 2006) but formerly referred to Lepidopleurida are noted (C).
- *Small patches, very close to the head, where they occur in deep grooves.
- **Investigated in one specimen and not observed in preserved material, but cannot be definitively excluded (Sigwart et al., 2013).
