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.
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]
The genus contains seven species: [4]
