In the former Bufo coccifer complex and removed from the synonymy of Bufo coccifer by Mendelson, Williams, Sheil, and Mulcahy, 2005, Sci. Pap. Nat. Hist. Mus. Univ. Kansas, 38: 11, where it had been placed by Savage, 2002, Amph. Rept. Costa Rica: 207. See photograph, map, description of geographic range and habitat, and conservation status (as Bufo cycladen) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 182. Mendelson, Mulcahy, Williams, and Sites, 2011, Zootaxa, 3138: 1–34, suggested that Incilius canaliferus is a member of a monophyletic Incilius coccifer group that includes Incilius coccifer, Incilius cycladen, Incilius ibarrai, Incilius pisinnus, Incilius porteri, and Incilius signiferOliver-López, Woolrich-Piña, and Lemos-Espinal, 2009, Fam. Bufonidae Mex.: 72–74, provided an account for Mexico (as Ollotis cycladen).
