Revision of the Japanese Species of the Aphid Genus Hamamelistes (Hemiptera, Aphididae, Hormaphidinae) Based on the Mitochondrial DNA Sequence Data

Aphids of the genus Hamamelistes host-alternate between Hamamelis (the primary host) and Betula (the secondary host). The taxonomy of the Japanese species has been in a mess. Eight different names have been used for them, and no combination between the primary-and secondary-host generations has been established. By sequencing their mitochondrial COII genes, we made it clear that three species occur in Japan : Hamamelistes miyabei (Matsumura) on Hamamelis japonica and Betula maximowicziana, Hamamelistes kagamii (Monzen) on H. japonica and B. grossa, and Hamamelistes betulinus (Horvath) on H. japonica, B. platyphylla, B. davurica and probably also on B. ermanii. The life cycles of the three species are reviewed, and synonyms are listed under the valid names.
