Caenodelphax Fennah was reviewed with reference to putatively allied species in the polyphyletic genus Delphacodes Fieber. Phylogenetic analyses using maximum parsimony of 34 morphological features for 15 ingroup and 3 outgroup taxa found that Caenodelphax sensu stricto did not group with putatively allied Delphacodes. Caenodelphax is here redefined as monotypic, and Flavoclypeus new genus is described to accommodate a clade of 8 species (6 transferred from Delphacodes and 2 transferred from Caenodelphax). Caenodelphax philyra was found to be a junior subjective synonym of Caenodelphax teapae.
