Coiba Island howler
Species of New World monkey
The Coiba Island howler (Alouatta coibensis) is a type of howler monkey, a type of New World monkey, endemic to Panama. Although the Coiba Island howler has been recognized as a separate species by a number of authorities since a 1987 study of its fingerprints, mitochondrial DNA testing found it does not differ from mantled howler populations in any significant way.[4] A reason given for treating it as a separate species is that the dermal ridges of its hands and feet differ from those of the mantled howler.[5]
A. c. coibensis is smaller than other Central American howler monkeys and has duller pelage than the Azuero howler, Alouatta coibensis trabeata.
