Keeled earless lizard (Holbrookia propinqua) female, municipality of Soto La Marina, Tamaulipas, Mexico (20 May 2002).

Holbrookia is a genus of earless lizards, known commonly as the lesser earless lizards, in the family Phrynosomatidae. The genus contains six recognized species, which are found throughout the Southwestern and Central United States and northern Mexico. They are characterized by having no external ear openings, presumably to prevent soil from entering their bodies when they are digging.
