Anacaena
Anacaena is a genus of small water scavenger beetles in the tribe Anacaenini, containing at least 150 species worldwide. Adults range 1.5–3.3 mm in length. The genus is characterized by a slightly expanded second maxillary palpomere relative to the third, lack of metallic lustre on the dorsal head, slight hydrofuge pubescence on proximal metafemora, and a non-carinate prosternum. Species-level identification relies primarily on aedeagus morphology.

These beetles belong to the subfamily Chaetarthriinae and tribe Anacaenini. They are aquatic or semi-aquatic insects found in freshwater environments.
