Heterelmis comalensis is a rare species of beetle known by the common name Comal Springs riffle beetle. It is endemic to Texas in the United States, where it occurs in only two springs. It is a federally listed endangered species of the United States.
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.
Heterelmis stephani was a rare species of aquatic beetle known by the common name Stephan's riffle beetle. It was endemic to Arizona in the United States, where it occurred in the Santa Rita Mountains before being declared presumed extinct. It was brown in color with small black dots on its wings.

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.
Heterelmis obesa is a species of riffle beetle in the family Elmidae. It is found in Central America, North America, and South America.
