CETTIA BRUNNESCENS (HUME, 1872) MONOTYPIC

We suggest retaining the English name Yellowishbellied Bush Warbler for C. acanthizoides , as this is the most widely distributed species, and the one for which the name is most apt. For C. brunnescens , the English name Hume’s Bush Warbler is appropriate and has been in long use, and for this reason was the name adopted in Rasmussen & Anderton (2005).
