Comment
In the Ranitomeya vanzolinii group according to the original publication, where comparative adult and larval morphology, advertisement call, molecular markers, a dot map of its distribution, as well as sorting earlier literature under different taxonomic names. Most recently this species was considered to be outlying eastern populations of Ranitomeya sirensis. Recorded in Bolivia (as Dendrobates biolat) by De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 57, Köhler, 2000, Bonn. Zool. Monogr., 48: 69; and Maldonado-M. and Reichle, 2007, Kempffiana, 3: 13-17. Melo-Sampaio and Souza, 2009, Herpetol. Rev., 40: 447, provided the first record (as Ranitomeya biolat) for Acre, Brazil. França and Venâncio, 2010, Biotemas, 23: 71–84, provided a record (as Ranitomeya biolat) for the municipality of Boca do Acre, Amazonas, with a brief discussion of the range.
