Resumen

Ameerega planipaleae is an endemic poison frog from the vicinity of Oxapampa on the western slope of the Cordillera Yanachaga-Chemillen, Provincia Oxapampa, Departmento Pasco, Peru. Most Ameerega species are relatively impoverished in diagnostic characters other than color pattern in life, which have been used commonly to distinguish species. This especially refers to the colors of the dorsum and the presence/absence of bright dorsolateral stripes as well as bright axillary, inguinal or calf spots. According to the original description of A. planipaleae, the few type specimens in life were dorsally dark brown grading into yellow on head with yellow dorsolateral stripes on each side from posterior part of the head to groin where they turned into a red inguinal spot. The adjacent upper thigh showed one to several additional red spots bordered by black that in part reached to the groin.
