Abstract

As described in Section 5.4.2, Imura (1996) divided about 1,000 species belonging to the subtribe Carabina of the world into eight (sub)divisions and 94 (sub)genera, and Březina (1999) recognized 114 (sub)genera. These researchers reasoned that there was such a large number of genera primarily on the basis of the considerable morphological diversity of this group. Examining phylogenetic relationships by means of the mitochondrial gene sequence indicates, however, that there are a number of examples where morphologically similar carabids are phylogenetically quite remote from each other, while there exist also many cases in which phylogenetically close species differ in morphology to a considerable extent. The present chapter will deal with the origins of the morphological as well as phylogenetic diversity of the carabid beetles.
