Fig. 2 Phylogenetic tree representing relationships within Discodorididae. The latter contains about 400 species and 40 in A warning for ecologists and conservation biologists using species checklists: How the European marine fauna 'lost' all of its 16 Discodoris species (Mollusca: Gastropoda)
Fig. 2 Phylogenetic tree representing relationships within Discodorididae. The latter contains about 400 species and 40 genera, only some of which are mentioned here, with special emphasis on the genera that contain species originally described in Discodoris. Tree terminal taxa are labeled with the specific epithet followed by the generic name of the original combination in parenthesis. The current generic names are given on the right side of the braces indicating the (few) species per genus mentioned. Assignment of a generic name to a clade is based on a type species that belongs to that clade (e.g., Discodoris boholiensis is the type species of Discodoris). All genera correspond to clades, with the exception of "Montereina", a metaphyletic group at the base of Discodorididae for which no autapomorphic, diagnostic features could be found. For additional information on phylogenetic analyses, authorship of species names, etc., see Dayrat (2010a)
