Didactyliini
Didactyliini is a small tribe of water scavenger beetles within the family Hydrophilidae, currently containing the single genus Didactylus. Members of this tribe are aquatic beetles distinguished by reduced tarsal segmentation, with only two visible tarsomeres on the fore and mid legs. The tribe was established to accommodate this unusual morphological condition, which separates it from other Hydrophilinae. The genus occurs in the Neotropical region, where species inhabit freshwater environments.
