Abstract
Phylogenetic analyses of 22 dorid nudibranch species and two outgroup (dendronotacean and notaspidean) species were performed using sequences from two different mitochondrial genes (16S rRNA and COI). Several methods of differential weighting (positional, transformational, and combined) were explored using character congruence between the linked data sets as an optimality criterion. Most weighting schemes gave an increase in congruence as well as phylogenetic signal. The optimal weighting scheme according to the criterion was successive weighting of each character (positional weighting) with 1/(number of steps) in combination with LN weighting of character changes (transformational weighting). The cladogram from the optimal weighting scheme was in general congruent with existing classifications. One exception is the genus Goniodoris, which was paraphyletic if Okenia aspersa was not also included.
