Concerning message #16234:
In our revision of the caryophyllidia-bearing dorids, Terry Gosliner and I found that the type species of Anisodoris and Diaulula belong to the same genus, and therefore these two names are synonyms, Diaulula having precedence. We also found that all caryophyllidia-bearing dorids are members of the same clade, thus, if we are correct, the presence of caryophyllidia is an important character for dorid classification.
The problem with species of Anisodoris is that this genus name has been widely used for species with and without caryophyllidia. It would be a very time consuming task to review all species of cryptobranch dorids and try to determine their taxonomic placement in light of the results of our phylogenetic hypothesis. So we preferred to provide diagnoses for all genera and leave for future research, or our colleagues research, to determine the taxonomic placement for all those hundreds of species names. When we wrote the diagnoses we were conscious that many of them where too inclusive or exclusive and would need further work after examining real animals.
Said so, "Anisodoris" nobilis lacks caryophyllidia, has a prostate with two distinctive regions, the anterior border of the foot is grooved and notched, and it has no jaws on the labial cuticle, therefore, and according to my subsequent paper (Valdés 2002), it should be placed in the genus Peltodoris.
I think the Forum is an ideal place for fine tuning and testing of proposed classifications, by examining and posting anatomical features of species that are overlooked in more general phylogenetic hypotheses and revisions of larger groups.
