Evolution, biogeography and systematics of moss-inhabiting flea beetles (Coleoptera: Chrysomelidae: Galerucinae)
Flea beetles (Alticini) are a highly diversified group of leaf beetles (Chrysomelidae) with about 8 000 known species from about 560 genera distributed worldwide except Antarctica. The major life strategy of flea beetles is external feeding on vascular plants, similarly to other leaf beetles. Howeve...
