Phylogenetic analysis of the subclass Pteriomorphia (Bivalvia) from mtDNA COI sequences.
Phylogenetic relationships within the subclass Pteriomorphia (Bivalvia) were examined using sequences of the mitochondrial cytochrome c oxidase subunit I gene. The resultant Minimum Evolution phylogenetic tree strongly supports the existing superfamily-level classification with all the members of each superfamily forming clades. At the same time, it is suggested that: (1) Ostreoidea shows a closer relationship to Pinnoidea and Pterioidea than to the other superfamilies; (2) Pectinoidea, Anomioidea, and Limoidea form a clade, (3) Arcoidea and Limopsoidea form a clade; (4) The subclass Anomalodesmata is closer to the subclass Heterodonta than to Mytiloidea; and (5) The subclass Pteriomorphia is monophyletic. Taking these results as well as published data for nuclear 18S ribosomal DNA (18S rDNA) and Myosin analyses into consideration, a new order-level classification system for Pteriomorphia is proposed.
