Relationships of almost all known Bagoini from the world (Holarctic, Afrotropical and Oriental Regions, and Australia) were analyzed using morphological characters. To define relationships with other Curculionidae and among the species within the tribe, 119 characters were used: 64 of these are genital structures, mainly from the males, where the penis and endophallus are endowed with many complex structures that are apparently unique in Curculionidae. In general, the genital characters appear conservative and tend to resolve relationship at more terminal levels of phylogeny. On the contrary, many external characters are strongly homoplastic, probably secondary modifications associated with their aquatic lifestyle, but which tended to resolve relationships among the lower nodes of the tree. On the basis of this analysis, we confirmed the monophyly of the tribe. Our phylogenetic reconstruction suggests a new taxonomic ordering of the tribe in genera and subgenera. The following taxa, previously considered as synonyms of Bagous Germar, 1817, are resurrected as valid taxa: Hydronomus Schoenherr, 1825 and Memptorrhynchus Iablokoff-Khnzorian, 1960 as genera; Parabagous Schilsky, 1907, Hydronoplus Fairmaire, 1898 (= Pseudobagous Sharp, 1917 syn. n.) (stat. n.) and Macropelmus Dejean, 1821 (= Pnigodes LeConte, 1876 syn. n.) (stat. n.) as subgenera. Azollaebagous gen. n. and Hydrillaebagous subgen. n. of Bagous are created. Among some genera, especially Bagous and its subgenera, we recognize a somewhat large number of species groups, distinguishable mainly by unique character states of the male genitalia. Monophyly of most of these appears well supported. Some of these groups are presently monotypic, but we ascertained that many of them have other representatives not yet described.

The six species of Lissorhoptrus LeConte known previously from Noth America north of Mexico are treated taxonomically. Two subspecies are raised in rank to species, Lissorhoptrus insularis Kuschel and Lissorhoptrus longitarsis Kuschel, new rank, and one species, Lissorhoptrus robbinsorum O'Brien, new species, is described. The nine species include one that attacks rice, Oryza sativa L., and two that attack wild rice, Zizania aquatica L. The new species L. robbinsorum has been reared from the aquatic grasses Echinochloa crus-galli (L.) and Echinochloa holciformis (H. B. K.) Chase. The genus and previously described eight species are redescribed, and the nine species are keyed. Photographs of the habitus and the male hind tibial mucro of all species and the male genitalia of selected species are provided.

The genus Miloderes Casey, 1888 is reviewed and three new species are described. The genus now has eight valid species: M. amargosensis sp. nov., M. mercuryensis Tanner, M. nelsoni Kissinger, M. panamintensis sp. nov., M. setosus Casey, M. tingi Tanner, M. ubehebensis sp. nov. and M. viridis Pierce. Miloderes allredi Tanner, 1974 is a new junior synonym of M. viridis Pierce, 1910. The relationships of the species are discussed based on morphological characters from external morphology as well as from the endophallus. A key to species is provided.
