Abstract. The sixteen genera of Cybocephalidae (Coleoptera) occurring worldwide are listed and keyed. The genera included are Amedissia Kirejtshuk and Mantič, Apastillus Kirejtshuk and Mantič, Cybocepha­lus Erichson, Endrodiellus Endrödy-Younga, Eupastillus Lawrence, Hierronius Endrödy-Younga, Horadion Endrödy-Younga, Pacicephalus Kirejtshuk and Mantič, Pastillocenicus Kirejtshuk and Nel, Pastillodes En­drödy-Younga, Pastillus Endrödy-Younga, Pycnocephalus Sharp, Taxicephomerus Kirejtshuk, Theticephalus Kirejtshuk, a description of a new genus, Microthomas T. R. Smith, with one new species, M. brevicornis T. R. Smith, from Bolivia, and a new genus, Conglobatus T. R. Smith, with two new species, C. armatus T. R. Smith from Central and South America and C. fullertoni T. R. Smith from Dominica. A key to genera, illus­trations of morphological features, and distributional data are provided. The genus Nodola Bréthes is found to be a new synonym of Cybocephalus Erichson. The transfer of Nodola chilensis Bréthes into Cybocephalus creates a secondary homonymy with C. chilensis Reitter. Nodola chilensis Bréthes is here given a new name, Cybocephalus brethesi T. R. Smith.
