Heterophasia, the sibias, is a genus of passerine birds in the laughingthrush family Leiothrichidae. They are found from the Himalayas to southern China and Sumatra.

Taxonomy

[edit]

The genus Heterophasia was introduced in 1842 by the English zoologist Edward Blyth to accommodate a single species, Heterophasia cuculopsis Blyth, 1842. This is the type species by monotypy.[1] The species is a junior synonym of Sibia picaoides, the long-tailed sibia, that had been described by Brian Houghton Hodgson in 1839.[2] The name Heterophasia combines the Ancient Greek ἑτερος/heteros meaning "different" with φασις/phasis meaning "appearance".[3]

[edit]

The genus contains seven species:[4]
