A molecular phylogentic study published in 2009 found that the genus Anas as then defined was non-monophyletic . Based on this analysis the genus was split into four proposed genera with the Baikal teal placed in the resurrected genus Sibirionetta that had been introduced by the German zoologist Hans von Boetticher in 1929 . The name Sibirionetta is derived from the Latin sibiricus for Siberia and the Ancient Greek nētta for a duck . The specific epithet formosa is from the Latin formosus for "beautiful". </P>
