Cretocrenis burmanicus, gen. et sp. nov. is described from Burmese amber and represents the oldest known amber inclusion of the family Hydrophilidae (Coleoptera: Polyphaga). The new genus resembles the small-bodied modern genera of the tribe Anacaenini and the subfamily Acidocerinae, and the morphology of the venter and male genitalia suggest that it belongs to the Horelophus+Crenitis Glade of the tribe Anacaenini.
The fossil is described in detail, illustrated, and compared with extant hydrophilid genera.
