Atelopus chiriquiensis (Critically Endangered), a species of harlequin toad, has, like other members of its genus, undergone a catastrophic decline, probably due to the fungal disease chytridiomycosis. The species occurred in the lower montane zone of Costa Rica and western Panama, but it is now believed to have disappeared from Costa Rica (last record in 1996), and might also have gone from Panama (last record in the late 1990s).
