标题：NOTES ON TAPACULOS (PASSERIFORMES: RHINOCRYPTIDAE) OF THE EASTERN ANDES OF COLOMBIA AND THE VENEZUELAN ANDES, WITH A NEW SUBSPECIES OF SCYTALOPUS GRISEICOLLIS FROM COLOMBIA
摘要：We analysed biometrics, plumage and voice and inspected specimens to study the taxonomy of various high elevation tapaculos Scytalopus of the Eastern Andes of Colombia and the Mérida Andes of Venezuela. In light of a lack of any diagnostic vocal, plumage or biometric character, we propose treating S. infasciatus as a subjective junior synonym of S. griseicollis . S. fuscicauda and S. meridanus are indistinguishable by morphology, but we propose treating S. fuscicauda as a subspecies of S. meridanus in light of small observed differences in introductions to songs, which require further investigation. As the names were published contemporaneously, we propose priority for S. meridanus over S. fuscicauda . S. meridanus and S. griseicollis as redefined are each diagnosable vocally, supporting species rank for both of them. S. griseicollis gilesi subsp. nov. is described from the Yariguíes mountains. The new subspecies differs from S. griseicollis in its darker plumage, lower acoustic frequency scolds and longer tail. The recently discovered Eastern Andes population of S. spillmanni differs from Ecuadorian populations in its shorter tarsus length and slower song, meeting the requirements for some, but not all, subspecies concepts. With the status of S. griseicollis , S. meridanus and S. spillmanni populations clarified, it becomes apparent that two undescribed Scytalopus populations of the lower montane zone of the west slope of the Eastern Andes and Venezuelan Andes each await formal description. Other undescribed taxa apparently related to S. griseicollis or S. meridanus are present in Serranía del Perijá and the northern East Andes. Notes on geographical variation in S. latrans and Myornis senilis in the Eastern Andes are presented. Various proposed species and subspecies concepts for allopatric populations are discussed.
