Abstract
A taxonomic revision of the genus Cenophengus LeConte, 1881 (Coleoptera: Phengodidae) is provided, including new data on geographic ranges of the species. This is the first time this genus has been recorded for Belize and in Honduras. Four new species (C.gardunoi, C.saasil, C.tsiik and C.zuritai) are described and a new synonymy (C.guerrerensis, Zaragoza-Caballero, 1991 = C.major Wittmer, 1976) is established. The study includes a key to the 30 valid species, diagnoses, descriptions, photographs and distribution maps.
