Comment

The three species groups were defined by Caramaschi and Sazima, 1985, Rev. Brasil. Zool., 3: 43–49, and further discussed by Bastos and Pombal, 1995, Copeia, 1995: 436–439. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543–583, suggested that Crossodactylus is the sister taxon of a clade composed of Megaelosia and Hylodes. Pimenta, Cruz, and Caramaschi, 2014, Arq. Zool., São Paulo, 45: 1–30, revised the Crossodactylus dispar complex.  Vittorazzi, Lourenço, Zattera, Weber, Recco-Pimentel, and Bruschi, 2021, Genet. Mol. Biol., 44 (2: e20200301): 1–9, reported on a ML tree of the species.
