Myiothera melanothorax was the scientific name proposed by Coenraad Jacob Temminck in 1823 who described a babbler from Java.[3][4]
The generic name Cyanoderma was proposed by Tommaso Salvadori in 1874 for babblers with slender and pointed beaks.[5]
It was later placed in the genus Stachyris, but since 2020 is recognised as a Cyanoderma species.[6][2]
