FIGURE 6 in The nomenclatural status of the nomina of amphibians and reptiles created by Garsault (1764), with a parsimonious solution to an old nomenclatural problem regarding the genus Bufo (Amphibia, Anura), comments on the taxonomy of this genus, and comments on some nomina created by Laurenti (1768)

FIGURE 6. Reproduction of part of the tree of anurans in Van Bocxlaer et al. (2009: 3) including their BUFONIDAE. The specific nomina are those used by these authors, whereas the generic nomina in the column on the right are those supported here, either for genera or subgenera (see text for details). Bidirectional arrows point to reported cases of successful hybridization resulting in adult specimens: (1) between Bufo bufo and Bufo viridis (Hemmer & Böhme 1974; Duda 2008); (2) between Bufo calamita and Bufo viridis (Flindt & Hemmer 1967; Hemmer 1973; Schlyter et al. 1991); (3) between Bufo terrestris and Bufo valliceps (Blair 1941; Moore 1955) and between Bufo fowleri and Bufo valliceps (Blair in Moore 1955); (4) between Bufo bufo and Bufo woodhousii (Blair 1972: 420). The larger grey rectangle includes all the species that must be maintained in the genus Bufo according to these data if the crossability criterion of Dubois (1988a-b, 2004c) is implemented. The darker grey rectangles includes species that could be placed in two distinct genera if the only reported case between Bufo bufo and Bufo woodhousii proved to be in error; in this latter case, several genera should be recognized for the species remaining in the lighter grey area.
