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. The species is a
junior synonym of
Sibia picaoides, the
long-tailed sibia, that had been described by
Brian Houghton Hodgson in 1839. The name
Heterophasia combines the
Ancient Greek ἑτερος/
heteros meaning "different" with φασις/
phasis meaning "appearance". ==Species==
