Combining citizen science, phylogenetics, and bioacoustics to inform taxonomy and conservation of the Near Threatened (Anura, Odontophrynidae).

Herein, basel on novel data gathered by citizens scientists and specialists, we contribute to the improvement of scientific knowledge and conservation of the Near Threatened in order to: 1) test for the first time the phylogenetic position and a species delimitation of through a molecular approach; 2) describe a larger sample of its advertisement call to properly encompass the species intraspecific variation; 3) describe for the first time the release call; and 4) provide novel insights on the species conservation status. Our 16S tree confidently grouped with , , and . The average sequence divergence between and its congeners ranged from 2.2% () to 9.1% (). Advertisement calls consisted of a single note with duration of 0.26-0.58 s, 17-41 pulses emitted at rate of 54.19-77.49 pulses/s and peak frequency of 775.19-947.46 Hz. Release calls consisted of a single note with duration of 0.04-0.43 s, 2-13 pulses emitted at rate of 21.17-81.58 pulses/s and peak frequency of 689.1-1,722.6 Hz. Additionally, our study strongly supports the notion that Citizen Science approaches can yield invaluable information concerning species' geographic distribution and conservation.
