Abstract
Spotted Munia Lonchura punctulata is a sparrow-sized estrildid finch native to tropical Asia. In this study, we used PCR-based method to determine the complete mitochondrial genome of Lonchura punctulata topela. The mitochondrial genome of Spotted Munia is a 16 824-bp circular molecule, which contains 37 typical mitochondrial genes (13 protein-coding genes, two rRNAs, and 22 tRNAs) and a 1247-bp A + T– rich region. The gene arrangement pattern is identical to Taeniopygia guttata and Passer montanus. All the start codons of PCGs are typical ATG, except for the COI and ND3 genes. TAN is the most frequent stop codon, and TAN and T– are also found very common. The non-coding region contains some inter-genic spacers and a control region. The phylogenetic trees from the Bayesian and neighbor-joining analyses, based on the complete mtDNA of 12 Passeriformes species, share similar topologies and high node support values. Lonchura punctulata topela has close relative with Taeniopygia guttata.
