RESUMO
The entire mitochondrial genome of Garrulax poecilorhynchus consists of 17 814 bp and containe 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and two control regions. The nucleotide composition of the mitogenome of G. poecilorhynchus is A = 5342 (29.99%), T = 4314 (24.22%), G = 2480 (13.92%), and C = 5678 (31.87%). The genome has an overall A + T content of 54.21%, which has a similar value among known genus Garrulax mitogenomes. All the tRNA genes display a typical clover-leaf structure. Garrulax poecilorhynchus share the closest relationship with other two species, G. perspicillatus and G. sannio. These data could serve to enrich the resource of genus Garrulax in systematic, population genetic, and evolutionary biological studies.

Garrulax sannio (Passeriformes, Timaliidae) was the medium-sized bird, whose plumage color was similar for both sexes. The complete sequence of the mitochondrial DNA genome from G. sannio used the polymerase chain reaction method. The genome (17 840 bp in length) contained 13 protein-coding genes, 2 rRNA (12S and 16S) genes, 22 tRNA genes and 2 control regions (D-loop). The base composition of G. sannio mitogenome A + T percentage was 52.22%. It is slightly higher than G + C 47.78% which was similar with other vertebrates. Through constructed phylogenetic tree, we could identify its taxonomic status. Therefore, mitochondrial genome was a best way to preserve genetic resources of species.
