Heterelmis glabra
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.[4] References
