Heterelmis glabra is a species of riffle beetle in the family Elmidae.

It is found in Central America and North America.

[1][2][3] 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.
