Elmidae, commonly known as riffle beetles, is a family of beetles in the superfamily Byrrhoidea described by John Curtis in 1830. Both adults and larvae are usually aquatic, living under rocks in fast-flowing shallow areas of streams, such as riffles, feeding on algae and biofilms. There are more than 150 genera and 1,500 described species in Elmidae. The oldest record of the group is Cretohypsilara from the Cenomanian aged Burmese amber.

Stenelmis lignicola is a species of riffle beetle in the family Elmidae. It is found in North America.
Heterelmis glabra is a species of riffle beetle in the family Elmidae. It is found in Central America and North America. The largest populations of this riffle beetle are found in springs associated with the upper Devils River in south-central Texas. Spring-adapted organisms such as this beetle have life-history patterns requiring surface components, which makes them more vulnerable to changes in spring flow that alter the surface habitat.
