Fulvetta cinereiceps (grey-hooded fulvetta) has been classified as belonging to the multi-clade babblers within Passeriformes. The complete mitochondrial genome of F. cinereiceps is lacking although there has been considerable phylogenetic research on babblers. Therefore, we aimed to determine F. cinereiceps’ mitogenome and investigate its phylogenetic relationships within the babblers and superfamily Sylvioidea. F. cinereiceps’ mitogenome is typically circular, 16,969 bp in size with a rich A+T content (52.7%), 13 protein-coding genes (PCGs), 22 tRNAs genes, 2 rRNA genes, a control region (CR) and a non-coding region (NC). We found strong support for F. cinereiceps being placed within Sylviidae (superfamily Sylvioidea)and for babblers being separated into two families, Sylviidae and Timaliidae, with four subfamilies within Timaliidae. This is one of many taxonomic arrangements for babblers and there is likely to be continuous debate until a consensus is reached. Consequently, our study’s complete mitochondrial genome of F. cinereiceps can be added to newly sequenced complete mitochondrial genomes and allow babbler taxonomy to be mapped with confidence.
