Keys to the species of the new genera are provided. Photos of habitus are included for most taxa and of genitalia of the new species. The following taxa are described as new in this paper: subtribes Ar-chariina, new subtribe, Erganiina, new subtribe, and Labaninina, new subtribe; and new species: Pseudoculio barclayi, new species,.P. confusicoxis, new species, P. crinitus, new species, P. promissus, new species, P. spiesi, new species, and P. vittatus, new species. Curculio guyanensis Rheinheimer is reassigned to the new genus Megaoculis, new combination. The following genera placed in Incertae sedis in Alonso-Zarazaga and Lyal are removed from the tribe: Allocionus Hus-tache, Balaninorhynchus Fairmaire, Bradyninus Fairmaire, Semicardius Hustache and Trichanthonomus Hustache.
