It is endemic to northeastern Brazil and occurs from northern Minas Gerais and Bahia to Maranhão, Piauí, Ceará, and Rio Grande do Norte.{{cite web |url=http://research.amnh.org/vz/herpetology/amphibia/Amphibia/Anura/Leptodactylidae/Leptodactylinae/Leptodactylus/Leptodactylus-troglodytes |title=Leptodactylus troglodytes Lutz, 1926 |author=Frost, Darrel R. |year=2016 |work=Amphibian Species of the World: an Online Reference.

Description
Adult males measure {{convert|46|-|53|mm|in|1|abbr=on}} and adult females {{convert|45|-|53|mm|in|1|abbr=on}} in snout–vent length. The tympanum is distinct. Males have more acuminate snout than females. Dorsal folds are absent and dorsolateral folds are indistinct or (usually) absent; lateral folds are also absent or interrupted. The belly is uniformly light.
The tadpoles grow to {{convert|43|mm|abbr=on}} in total length (Gosner stage 36).
