. Characters of the head of larvae of Metrius contractus Eschscholtz, Ozaenini and Paussini are interpreted phylogenetically. The monophyly of Metriini + Ozaenini + Paussini is substantiated by several synapomorphies such as hyperprognathism and strong constriction of the neck. Ozaenini and Paussini together form the sister-group of Metriini. Ozaenini are paraphyletic. The monophyly of Paussini + Ozaenini excluding Pachyteles is indicated by two possible synapomorphies. Several synapomorphies are shared by Physea+ Paussini. Secondary prognathism, large membranous submento-mental area and other derived features are considered autapomorphies of Paussini. Paussini excluding Platyrhopalopsis are characterized by the loss of the palpifer. The monophyly of a group which comprises Geadephaga excluding Trachypachini is suggested by several synapomorphic features. A very basal position of the metriine-paussine lineage within Carabidae is indicated by several plesiomorphic features. A hypopharyngeal filter apparatus with a dense fringe of well-arranged, long hairs is a possible autapomorphy of Anisochaeta. The results of this study do not indicate a close relationship between the metriine-paussine lineage and the tribes Brachinini and Crepidogastrini as has been suggested in recent works.
