摘要: ABSTRACT . We describe a new species of wren in the genus Thryophilus (Troglodytidae) based on analysis morphological, vocal, and genetic variation. Individuals are readily separated field or museum from those any other species, including its closest relatives T. rufalbus nicefori, by combination traits including, but not limited to, plumage coloration upperparts, pattern barring wings tail, overall smaller body size, richer repertoire syllable types, shorter trills, distinctive terminal syllables. The is allopatrically distributed relation to congeners, being restricted dry Cauca River Canyon, narrow inter-Andean valley enclosed Nechi Refuge rainforests northern sectors Western Central Andes Colombia. pairs have been found only remnant patches forest scrub at 250– 850 m elevation. This newly discovered uncommon threaten...
