Seicercus grammiceps The Sunda warbler (Phylloscopus grammiceps) is a species of Old World warbler in the family Phylloscopidae.

The Sunda warbler was previously placed in the genus Seicercus.

A molecular phylogenetic study published in 2018 found that neither Phylloscopus nor Seicercus were monophyletic.

[2] In the subsequent reorganization the two genera were merged into Phylloscopus which has priority under the rules of the International Commission on Zoological Nomenclature.
