The published complete mitochondrial genome of Blue-fronted Redstart (Phoenicurus frontalis) is a chimera and includes DNA from Pink-rumped Rosefinch Carpodacus waltoni eos (Aves: Passeriformes).

ABSTRACT

The complete mitochondrial genome of Blue-fronted Redstart (Phoenicurus frontalis), GenBank accession number MT360379 (NC_053917), was published by Li and colleages in 2020. Here we show that this mitogenome is actually a chimera containing DNA fragments of both P. frontalis (15,518 bp, 92.5%) and Pink-rumped Rosefinch (Carpodacus waltoni eos, 1258 bp, 7.5%). This mitogenome has been re-used in at least three phylogenies. Our study confirms that mitogenomes are best verified with multiple gene trees, and that any anomalies should be investigated by direct comparison of sequences.
