How long does it take to know a species? Redescription, vocalization, and chigger mites infestation pattern in the centenary emBrachycephalus/em emgarbeanus/em (Anura: Brachycephalidae).

Although we celebrate the centennial of Brachycephalus garbeanus' discovery, little progress has been done on understanding this species' biology apart from a few morphological and ecological studies, which includes its redescription based on three specimens from the type-series, microhabitat use, sexual dimorphism in body size, and feeding habits.
