Nomenclatural changes in New World Curculionidae (Curculioninae (Cryptorhynchini, Molytini), Cossoninae)

The genus Epacalles Kissinger with its one included species, E. inflatus (Blatchley), is transferred from Cryptorhynchini to Molytini, Conotrachelina Epacalles is closely related to species placed in the genera Aenesias Champion and Lepilius Champion. Generic definitions need to be reconsidered in this group of taxa. A lectotype is designated for Zascelis oblonga Horn (Cryptorhynchini) and this species is transferred to the genus Cnemidoprion as Cnemidoprion oblongus (Horn). Character states distinguishing C. oblongus from the only other species in the genus, C. serratipes Marshall are presented. The genus Crematogasterobius Hustache and Bruch originally described in Curculioninae, Cryptorhynchini is transferred from Cossininae, Acamptini, back to Cryptorhynchini and is recorded for the first time from Mexico. A lectotype is designated for Menares pilicornis Champion and this genus and species are transferred from Curculioninae, Cryptorhynchini, to Cossoninae, Acamptini. Menares is distinguished from other Acamptini on the basis of toothed femora and a maculate elytral pattern.
