Abstract
A cladistic analysis of 14 genera of hemispheric flea beetles based on adult morphological characters is presented. A multiple origin of hemispheric body shape is concluded. The phylogenetic position of the hemispheric genus Argopistes Motschulsky, 1860 is studied and its attribution to the subtribe Diboliina is proposed. A phylogenetic analysis of subtribe Diboliina using cladistic methods and based on morphological characters is carried out. Inferred from the results of this analysis this subtribe retains four genera: Argopistes, Dibolia Latreille, 1829, Megistops Boheman, 1859, and Paradibolia Baly, 1875. A diagnosis of the subtribe Diboliina, a redescription, a key to genera, and an annotated list of genera are given. Trends in morphological transformations in Diboliina and other alticines are discussed.
