Comments: Formerly occurred from Frisco Hot Spring, New Mexico, to near the mouth of the Gila River:  it was perhaps more widespread in spring-fed creeks and marshes of southern Arizona between 900 and 1500 m above sea level.  Inhabits vegetated springs and margins, pools and backwaters of creeks and small to medium rivers.  Usually found in shallow, warm water.
