The new Anomaloglossus are known only from the Chagres Highlands in east-central Panama, but it cannot be safely concluded that they are endemic to this area. The best known part of these highlands is the Piedras-Pacora Ridge on the continental divide, which has been suggested as a “premontane forest refuge for some small part of the fauna that is barely surviving the climatic-vegetational changes of the Pleistocene. It is conceivable that Anomaloglossus occurs more widely in Panama, possibly, in fragmented pockets along the broken Serranía de San Blas and northern part of the Serranía del Darién, where collecting has been very sporadic.
