SCYTALOPUS STILESI, A NEW SPECIES OF TAPACULO (RHINOCRYPTIDAE) FROM THE CORDILLERA CENTRAL

摘要: We describe Scytalopus stilesi, an overlooked species of tapaculo endemic to Colombia, on the basis a series eight specimens taken in 2002 and comparative analyses its vocalizations, mitochondrial DNA sequences, dis- tribution. The new ranges northern half Cordillera Central Colombian Andes Departments Antioquia, Caldas, Risaralda, cloud forests between 1,420 2,130 m above sea level. song, calls, female song differ distinctly from those all other known taxa. Phylogenetic based sequences cytochrome-b gene strongly suggest affinities with S. robbinsi southwestern Ecuador two as-yet- undescribed tapaculos Andes. stilesi coexists locally with, though it is ecologically segregated from, atratus, latrans, spillmanni. mid-elevation premontane wet which restricted have been subject severe deforestation fragmentation. is, how- ever, relatively common continuous mature-forest remnants, large primary-forest fragments, riparian forests, tall secondary-forest patches. employed geo- graphic information system (GIS) approach model potential distribution assess conservation status under International Union for Conservation Nature (IUCN) criteria. does not qualify as threatened according criteria, but should be regarded near threatened. numerous bird that are need more effective conservation.
