A phylogenetic revision of the broad-nosed weevil genera Minyomerus Horn, 1876, and Piscatopus Sleeper, 1960 (Entiminae: Tanymecini) is presented. Piscatopus was considered monotypic, comprised solely of P. griseus, whereas Minyomerus formerly was comprised of seven species. This revision includes full redescriptions of the eight previously described species in these genera in addition to descriptions of nine new species. In conjuction with the traditional taxonomic descriptions, a cladistic parsomony analysis of morphological and genetic characters was carried out in WinClada, utilizing matrices of characters coded and stored in the mx content management platform. The data stored therein is available to the public. The results of the cladistic analysis place Piscatopus griseus within the genus Minyomerus, sister to M. laticeps and M. rutellirostris (anticipated), and thus Piscatopus is demoted as a junior synonym of Minyomerus.
