Figure 2 in High-level taxonomic splitting in allopatric taxa causes confusion downstream: a revision of the nudibranch family Сoryphellidae
Figure 2. Part of the maximum likelihood-based phylogenetic tree of Flabellinoidea s.l., showing relationships within the family Coryphellidae. Each branch is coloured according to the primary species hypothesis sensu Korshunova et al. (2017a) and provided on the left. Revised identifications representing the result of the present study are provided on the right. Numbers above branches indicate the bootstrap values (for BS> 60). Blocks on the right indicate species delimitation results: coloured blocks refer to groups matching the initial species hypothesis, grey blocks indicate results when the initial species hypothesis is not supported by a delimitation method. Abbreviations: JC, Jukes–Cantor model; K80, Kimura 2-parameter model; SD, Simple distances.
