New species described and illustrated: Adesmus nigrolineatus sp. nov. from Mexico (Oaxaca). From Costa Rica: A. moruna sp. nov. (Heredia); Corcovado bezarki sp. nov. (Guanacaste); Alampyris fuscus sp. nov. (Guanacaste), Cariua gen. nov. type species C. sulphurea sp. nov. (Guanacaste). From Bolivia: Phoebemima albomaculata sp. nov. (Cochabamba); Ipepo gen. nov. type species I. dilatatus sp. nov. (Santa Cruz). From Brazil: Adesmus facetus sp. nov. and Canarana arguta sp. nov. (Rondônia). A new record from Costa Rica of Piruanycha pitilla Galileo & Martins, 2005 is added. The three new species of Adesmus are recognized: A. nigrolineatus by the longitudinal black stripes on elytra; A. moruna by the elytra entirely black; A. facetus by the white belts behind the middle of the elytra and white maculae on apical quarter. Phoebemima albomaculata is characterized by the white macula on the elytral suture. Corcovado bezarki sp. nov. is distinguished by the black antennal scape and whitish flagelomeres. Canarana arguta sp. nov. has prothorax and urosternites I-IV covered by dense yellowish pubescence. Alampyris fusca sp. nov. differs from A. cretaria by the antenômere III longer than scape. Cariua sulphurea sp. nov. is distinguished by the urosternites covered by compact white pubescence and Ipepo dilatatus is characterized by the elytra with three carinae.
