Range Description

This very poorly known species is known only from four locations in eastern Sonora, Mexico. Its distribution is probably very imperfectly known, and the distribution map is based on the assumption that it occurs between the known localities. The known localities are: the Sierra Manzanal (type locality); the Sierra Baviacora; in the drainage of the Rio Yaqui; and at El Chorro (8 km northeast of Nacori Chico in the Sierra Occidental). The first two named localities in the drainage of the Rio Sonora. Its elevational range is 1,050 to 1,425 m asl.
