Cnemidophorus laredoensis

The Laredo striped whiptail (Aspidoscelis laredoensis) is a species of lizard found in the southern United States, in Texas, and northern Mexico in Coahuila and Tamaulipas. Some sources believe it to be the result of extensive hybridization between the Texas spotted whiptail, Aspidoscelis gularis and the six-lined racerunner, Aspidoscelis sexlineatus. It is one of many lizard species known to be parthenogenic.
