Interpretive Summary: Weevils are one of the largest families of beetles with many agricultural pest species. Their great number, similarity, and variability render them difficult for identification. However, in some instances their identities have been obscured by inadequate study. The present paper explores a very common group of North American weevils, which has been avoided by taxonomists since Casey in the 1920's claimed to have recognized a total of 64 species. The paper clarifies the validity of the proposed names and identity of the currently known 16 species. This paper provides for the first time a key for scientists and action agencies to identify this group of weevils
Odontocorynus Schönherr is revised and transferred from Madopterini, Zygobaridina to Madarini, Leptoschoinina (new placement). The various species included occur from southern Canada to Costa Rica, but are absent on the Pacific side of the Rocky Mountains. Previous records from Brazil are rejected, and one collection from El Salvador is treated as suspect. Twelve known and four new species are recognized: O. creperus Boheman as type species, O. calcarifer Prena sp. n. [United States], O. falsus (LeConte), O. histriculus Casey, O. larvatus (Boheman), O. latiscapus Champion, O. luteogramma Prena sp. n. [Mexico], O. nunume Prena sp. n. [Mexico], O. procerus Prena sp. n. [Mexico], O. pulverulentus (Casey), O. salebrosus (Casey), O. subvittatus Casey, O. suturaflava Champion, O. tectus (Champion) comb. n. (from Geraeus), O. townsendi (Casey) comb. n. (from Nicentrus), and O. umbellae (Fabricius) comb. n. (from Baris). Lectotypes are designated for O. falsus, O. larvatus, O. pulverulentus, O. salebrosus, and O. scutellumalbum (Say). The following new synonymies are proposed: O. creperus [=O. limatulus, O. subglaber, O. vernicicollis (all Casey 1920)]; O. larvatus [=Nicentrus contractus Casey 1892]; O. pulverulentus [=O. coloradensis, O. lulingensis, O. densissimus (all Casey 1920)]; O. salebrosus [=Centrinus denticornis, C. pinguescens (both Casey 1892), O. alternans, O. boonei, O. convergens, O. convexus, O. cribrum, O. dakotanus, O. dallasianus, O. defectus, O. greeleyi, O. ignotus, O. inflaticollis, O. inspectus, O. iowensis, O. latiusculus, O. longicollis, O. missourianus, O. ochreosus, O. onagensis, O. parallelus, O. parvus, O. pennianus, O. prominens, O. pusillus, O. quadricollis, O. regularis, O. robustus, O. rotundicollis, O. snowi, O. vicksburgensis (all Casey 1920)]; and O. umbellae [=Centrinus scutellumalbum Say 1831, O. advena, O. adjunctus, O. amputatus, O. atokanus, O. divisus, O. fultoni, O. illini, O. incertus, O. lineatellus, O. rufobrunneus, O. semiruber, O. subabruptus, O. subaffinis, O. unilineatus (all Casey 1920), O. amazonicus, O. fluviatilis, O. glabellus (all Casey 1922)]. A key for identification is provided.
