Lower Cretaceous beedes belonging to the extant tribe Ommatini (Coleoptera: Cupedidae: Ommatinae) are revised and six new species proposed in the extinct Eurasian genus Cionocokus: Cionocoleus tanae sp. n., Cionocoleus olympicus sp. n. (Yixian Formation, China); Cionocoleus elizabethae sp. n., Cionocoleus watsoni sp. n., Cionocokus minimus sp. n. (Weald Clay Group, UK); and Cionocokusjepsoni sp. n. (Purbeck Limestone Group, UK). New morphological data is provided for Cionocoleus magicus and Cionocokus cervicalis stat. n. ofwhich Cionocoleusplaniusculus is considered a synonym (Yixian Formation). Cionocoleus punctatus comb. n. is considered the oldest record (Upper Jurassic; Kazakhstan) of this presumably xylophagous, warm climate genus. A simple key is provided to all known species of Cionocokus. [ABSTRACT FROM AUTHOR]
