| Research Abstract |
As materials of this project, 60 species of the family Histeridae (Coleoptera) were available for phylogenetic molecular analysis, the materials were collected in Japan and Indonesia, and also contributed by many scientists of the world. Of them, 5 families, 8 subfamilies, 29 genera and 49 species have been analyzed their DNA. Molecular analysis of this project were used nuclear 28S, mitochondria ND2 and 16S. It was achieved rather good results of 28S, then I constructed the phylogeny of histrid beetles by using 28S, mainly.
Phylogeny of the family Histeridae is constructed. The tree shows monophyly of some tribes, but on some taxa, e.g. Dendrohilinae, non-monophyly. Bootstrap value is low of the tree among subfamilies. Topology of the molecular tree, however, shows consistency with morphological phylogeny.
It is difficult to show the mechanisms of morphogenesis of the family Histeridae. Because analysis of the mechanisms is depended on the result of phylogenetic analysis. I found some consistency and inconsistency between molecular and morphological trees under this project. Such inconsistencies will be clue to resolve parallelism and convergence on the beetles. Dr. Mazur and I gathered information of biology of the histrid beetles. The information will be useful as mapping characters on trees in further study.
