Our register was made approximately 1000 km southwestern far from the closest known occurrence of the species, in Uarini, Amazonas, Brazil, and it is the first record of Nectocaecilia to the region of the Juruá Sub-basin, and to the state of Acre, Brazil. This discovery reinforces that N. petersii can be widely distributed in Amazonia, probably being just less common than P. kaupii and T. compressicauda, which are more numerous in scientific collections (Maciel and Hoogmoed, 2011).
In fact, elements that drive demographic dynamics in populations of caecilians remain unknown, especially when referring to aquatic species.
