Nerodia paucimaculata, commonly known as the Concho water snake, is a species of mostly aquatic, nonvenomous colubrid snake native to Texas in the United States.
Geographic range
It is found only in west-central Texas in the Colorado and Concho river systems, in Coke, Runnels, San Saba, and Tom Green counties.
Conservation status
Due to its limited range, it was considered a threatened species in the state of Texas.[2]
Taxonomy
It was once considered to be a subspecies of the Brazos water snake, Nerodia harteri, but was elevated to full species status by Densmore et al. in 1992.[3]
Description
The Concho water snake grows to a total length of 16 to 32 inches (41–81 cm), and looks very much like Nerodia harteri, but tends to be more red in color and has no dark markings on the underside.
