Distribution. Western Atlantic—Bermuda, USA (Florida), Bahamas, Cuba, Jamaica, Puerto Rico, U.S. Virgin Islands, Gulf of Mexico, Curaçao, Trinidad and Tobago, Venezuela to Brazil (Pará, Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe, Bahia, Espírito Santo, Rio de Janeiro, São Paulo, Paraná, Santa Catarina) (Rathbun 1918; Chace & Hobbs 1969; Crane 1975; Powers 1977; Abele & Kim 1986; Bezerra 2012; Masunari et al. 2020).
Remarks. Previous records on the coast of São Paulo include São Sebastião (Rathbun 1918; Luederwaldt 1919a, 1929; Crane 1975; Bezerra 2012), Santos (Rathbun 1918; Luederwaldt 1919a, b; Crane 1975), Cananéia (Gerlach 1958), and Caraguatatuba (Bezerra 2012). It is often confused with the sympatric species L. cumulanta from Pará to Rio de Janeiro and with L. uruguayensis in the sympatric area from Rio de Janeiro to Santa Catarina (Bezerra 2012; Masunari et al. 2020). The species name has been sometimes wrongly used as “ leptodactylus ”, but Rathbun’s original name was “ leptodactyla ” (Bezerra 2012; Shih et al. 2016). Sequences accession number (GenBank): CCDB 1950—16S (KU313180), COI (KU313195) (Mantelatto et al. 2018a).
