PHYLOGENY OF ANASPID TAXA AS INFERRED FROM AMINO-ACID-SEQUENCES OF MONOMERIC MYOGLOBINS

Phylogenetic relationships among five sea-hare species (order Anaspide a) were inferred from analyses of orthologous amino acid sequences of monomeric myoglobins. The genus Aplysia is shown to be monophyletic, b ut the data do not support the clustering of A. kurodai and A. limacin a into the subgenus Varria to the exclusion of A. juliana. Rather, A. juliana and A. kurodai are shown to be phylogenetically closer to each other than either is to A. limacina. The inferred molecular phylogene tic arrangements support neither the assignment of Dolabella to a dist inct anaspid family nor the separation of Bursatella from Aplysia and Dolabella..
