Abstract
Eleven new species of chromodorid nudibranch are described from New Caledonia. There are three new species of Glossodoris, four of Hypselodoris, and single species of Cadlinella, Noumea, Durvilledoris, and Thorunna. Pink species with a white border are compared as the ‘Noumea romeri colour group’ and new species of Noumea, Durvilledoris and Hypselodoris which fall into that colour group are compared with Noumea romeri, N. simplex, Thorunna speciosus, Hypselodoris rosans, and Chromodoris albolimbala.
