In the Ranitomeya fantastica group according to the original publication, where external morphology (including tadpole mouthparts), molecular markers, and the advertisement call were detailed. In the Ranitomeya reticulata species group of Brown, Twomey, Amézquita, Souza, Caldwell, Lötters, von May, Melo-Sampaio, Mejía-Vargas, Pérez-Peña, Pepper, Poelman, Sanchez-Rodriguez, and Summers, 2011, Zootaxa, 3083: 47, and who provided an account on page 54–55. Records from the lower Huallaga River, San Martin Province, Peru, of nominal Ranitomeya fantastica were reassigned by Muell, Chávez, Prates, Guillory, Kahn, Twomey, Rodrigues, and Brown, 2022, Mol. Phylogenet. Evol., 168 (107389): 1–10, to Ranitomeya summersi. These authors also suggested the possibility that Ranitomeya fantastica and Ranitomeya summersi might be conspecific.
