Similar to Incilius cavifrons (as Bufo) according to the original publication. See map, description of geographic range and habitat, and conservation status (as Bufo spiculatus) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 191. Mendelson, Mulcahy, Williams, and Sites, 2011, Zootaxa, 3138: 1-34, suggested that this species is a member of a monophyletic Incilius valliceps group and in a subgroup they referred to as the Forest Group (the name Incilius cristatus subgroup is available—DRF) that includes Incilius aucoinae, Incilius cavifrons, Incilius campbelli, Incilius cristatus, Incilius leucomoyos, Incilius macrocristatus, Incilius melanochlorus, Incilius spiculatus, and Incilius tutelariusOliver-López, Woolrich-Piña, and Lemos-Espinal, 2009, Fam. Bufonidae Mex.: 91–93, provided an account for Mexico (as Ollotis spiculata). Arreortúa, Flores de Anda, Simón-Salvador, Santiago-Dionicio, and González-Bernal, 2021, Amph. Rept. Conserv., 15 (2: e281): 31–39, described larval morphology and provided natural history notes.
