Based on intrinsic morphological and extrinsic bionomic characters, the systematic position of the weevil tribe Acentrusini Alonso-Zarazaga, 2005 (Coleoptera: Curculionidae: Curculioninae) was determined. Maximum parsimony and Bayesian inference as well as nonmetric multi-dimensional scaling were used to analyze 34 morphological characters of adults, complemented by four host plant characters associated with particular weevil tribes. Sixteen species belonging to two subfamilies (Brachycerinae, Curculionidae) and seven tribes (Acentrusini, Anthonomini, Ellescini, Erirhinini, Smicronychini, Storeini, Styphlini) of the family Curculionidae and one outgroup species (Attelabidae) were studied. Phylogenetic and multi-dimensional analyses revealed the tribe Smicronychini as most closely related to Acentrusini. Of the tribes of Curculioninae studied, Styphlini, Anthonomini and Ellescini showed a certain degree of phylogenetic relation to Acentrusini, whereas Storeini were found to be least related.
