ENDANGERED SPECIES ACT PROFILE

PROTECTION STATUS: Endangered

YEAR LISTED: 1997

CRITICAL HABITAT: 54 acres of surface habitat finalized in 2013

RECOVERY PLAN: None

RANGE: Comal Springs in Comal County, Texas and San Marcos Springs in Hays County, Texas

THREATS: Decreased spring flow due to increased use of groundwater resources; drought; increased flooding and erosion, pollution, siltation, and storm-water runoff associated with urbanization; and the presence of exotic species

POPULATION TREND: Comal Springs riffle beetles have been collected from spring runs 1, 2 and 3 at Comal Springs and a single specimen was taken from San Marcos Springs. It is not known whether this species historically ranged in other springs that are now dry almost all the time, such as San Pedro Springs and San Antonio Springs.
