Incilius is a genus of toads in the true toad family,

Incilius valliceps that predominantly occur in disturbed habitats.[4]

Taxonomy and systematics

This genus was first described in 1863 by Edward Drinker Cope who designated the type species as Incilius coniferus. This proved unpopular and these toads were known under the genus Bufo until the early 2000s.[1]

The current delineation of the genus follows Mendelson et al. (2011) who brought Cranopsis/Cranophryne/Ollotis and Crepidius/Crepidophryne into

sister taxon of Anaxyrus.[1]

Another discussion has been the taxonomic level at which the genus is recognized. Incilius did not see wide recognition before the large-scale revision of amphibian systematics by

Bufo valliceps group" and some related species. However, others have argued that Incilius should be treated as a subgenus of Bufo.[7]

Species

There are at present 39 species:[1]

The AmphibiaWeb recognizes Incilius intermedius (Günther, 1858) as a valid species,

Incilius occidentalis (Camerano, 1879).[1]

One fossil species, Incilius praevius (Tihen, 1951), is known from the Early Miocene (Hemingfordian) of Florida.[8]
