Under Sibley and Monroe, the Sylviidae (Old World warblers) are a huge family consisting of tesias, warblers, tailorbirds, grass birds, laughing thrushes, and babblers. To render the name of this new Sylviidae, I've referred to CJV names for the Sylviidae or Sylviinae under older classifications.
The main divisions are:
Acrocephalinae (tesias, stubtails, bush warblers, grasshopper warblers, reed warblers, tailorbirds, leaf warblers, and flycatcher warblers)
Megalurinae (grassbirds)
Garrulacinae (laughing thrushes, liocichlas, etc.)
Sylviinae (jungle babblers, scimitar babblers, wren babblers, sibias, yuhinas, leiothrix, barwings, fulvettas, parrotbills, whitethroats, etc.)
The distribution of the Sylviidae in East Asia can be seen at Tzung-Su Ding's Distribution of Sylviidae in East Asia.
