Ptilodactylidae
Ptilodactylidae is a family of beetles belonging to the Elateriformia. There around 500 extant species in 35 genera. They are generally associated with riparian and aquatic habitats. The larvae generally live associated with rotting wood or vegetation, or within gravel and detritus on the edge of water bodies. The larvae of some species feed on submerged rotting wood or on plant roots, while the adults of some species are known to feed on fungus with modified brush-like maxillae.Lawrence, John F..

Byrrhoidea
Byrrhoidea is a superfamily of beetles belonging to Elateriformia that includes several families which are either aquatic or associated with a semi-aquatic habitat. Other than the superfamily Hydrophiloidea, most of the remaining Polyphagan beetles which are aquatic are in this superfamily. Description Adults of many Byrrhoidea have exocone eyes (with expanded corneal lens). The anterior edge of the scutellar shield is often abruptly elevated (except in Psephenidae and Cneoglossidae). A variety of byrrhoids have the first three abdominal ventrites solidly fused together. Larvae of most Limnichiidae have one pair of anal hooks on the tenth abdominal segment, while Cneoglossidae and Ptilodactylidae have three or more hooks on each side of this segment. Larvae of Lutrochidae and Elmidae, as well as the limnichiid genus ''Hyphalus'', have anal gill tufts. Almost all byrrhoid larvae have anterior abdominal spiracles that are biforous (or bilabiate) in shape. The degree of ...
