Eleutherodactylus augusti reaches an adult length between 6-9 cm (2.5-3 in).
In North America, Eleutherodactylus augusti is found along a narrow band from central Texas into southeastern New Mexico; a separate population also occurs in southern Arizona. This species is also found throughout many of the major mountain ranges in Mexico.
Eleutherodactylus augusti is a shy frog rarely seen in the open. Eleutherodactylus augusti climbs rocks and walks with its entire body held above the ground. When captured, it will puff up to several times its body size.
Breeding occurs from February to May during the rainy season. Eleutherodactylus augusti lays its eggs in a foam nest away from standing water; the tadpoles undergo direct development, where the tadpoles transform inside the eggs and emerge as small frogs.
Eleutherodactylus augusti can be found in limestone caves and crevices, but it is known to utilize kangaroo rat burrows in southeastern New Mexico.
The barking frog is not a protected species in Texas and can be legally collected with a hunting license.
The single species Eleutherodactylus augusti found in Texas, E. a. latrans, is found from central Texas southwest to Del Rio, then northwest through west Texas to the southeastern corner of New Mexico.
