| Outline of Final Research Achievements |
To investigate the long distance dispersion between Old and New worlds by past intercontinental land connections, phylogenetic relationships of cerambycid beetles belonging to the tribe Acanthoderini (Insecta, Coleoptera, Cerambycidae) were analyzed based on molecular data. This tribe is known to flourish in Central-South America but some genera are distributed from Central America to North America, and also two genera are common to Europe and North Asia. With this disjunct distribution, it was expected to prove a hypotheses that the ancestor of this group had been distributed from Eurasia to North America, then spread their distribution to South America and East Asia. However, the results indicated that the tribe is not a monophyletic but multi-lineage group, and most of the assumed hypotheses on dispersion of the tribe were not supported. Besides, the result suggested the necessity of systematic review of this tribe based on plenty of samples.
