A redescription of the poorly known Central American toad Inciliustacanensis (Anura, Bufonidae), with a summary of its biology and conservation status.

Based on examination of most of the existing museum specimens of the rare bufonid frog Inciliustacanensis , we present a redescription and new diagnosis for this species. The species is limited to small region of the Pacific chain of volcanoes in southeastern Chiapas, Mexico, and adjacent areas of Guatemala. The species has not been observed in the wild since 1984 and may have been reduced or eliminated by regional epidemics of chytridiomycosis.
