The Neotropical genus Pseudopaludicola includes 21 species, which occur throughout South America. Recent studies suggested that the population of Andaraí, in the state of Bahia, is an undescribed species, related to P. pocoto. Herein we formally describe this new species from lowlands of eastern Brazil. Recognition of this new species is supported by adult morphology, advertisement call, karyotype, and molecular data. It is diagnosed mainly by its small size, terminal phalanges knobbed (lack any expansion of the digital tips), proportionally short hindlimbs, 11 pairs of chromosomes, and advertisement call composed of series of three-pulsed notes, emitted at a high rate. In addition, we report for the first time the presence of P. pocoto in the campo rupestre (rupestrian grasslands) of Chapada Diamantina, a population with a much darker dorsal coloration than the population from the type locality. We also redescribed the advertisement call of P. falcipes based on recordings from topotypic males.

Etymology. The specific name honors Antoine Hercule Romuald Florence. Better known as Hercule Florence, a French artist, painter, polygrapher, and inventor, is acknowledged as the inventor of photography in Brazil in the 19th century. After his return from the Langsdorff’s expedition (from 1826 to 1829), Florence developed a system able to properly describe animal sounds, transcribing them into a five line music staff (Florence 1831, 1876; Toledo & Araújo 2017). Such method, termed as “Zoophonie” by Florence, was the first universal method of describing animal sounds and he is therefore designated as the “father of bioacoustics” (Vielliard 1993; Toledo & Araújo 2017). At least these two techniques (photography and zoophony = bioacoustics) are fundamental for species description nowadays (Köhler et al. 2017). Specifically, bioacoustics has proved to be efficient in clarifying the taxonomy of the genus Pseudopaludicola (as in the present study).
