Abstract
Phylogenetic trees have been constructed using mitochondrial ND5 gene sequences of 85 specimens representing 40 species belonging to the division Lipastromorphi of the subtribe Carabina (= genus Carabus s. lat.) of the world. In the trees constructed by several methods, there have been recognized a basal split into two lineages, A and B, which are further divided into 2 (A1 and A2) and 9 (B1-B9) sublineages, respectively. Each sublineage and the clustering of the species in the trees are more or less linked to their geographic distribution. Morphology of the species within A1 or A2 in the lineage A is similar, and the species in most of the sublineages in the lineage B are common in a number of important morphological characters in spite of their long evolutionary histories. Whilst such a morphological stability, considerable morphological changes may be recognized upon or after split of lineages and sublineages. Based on the molecular phylogeny together with the morphological data, the pattern of diversification is discussed.
