Abstract

The white-tailed tropicbird, Phaethon lepturus (Pelecaniformes, Phaethontidae) is a tropicbird, smallest of three closely related seabirds of the tropical oceans and smallest member of the order Pelecaniformes. Here, we first determined the complete mitochondrial genome of while-tailed tropicbird. The mitogenome (17,773 bp) was composed of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 putative control region. Most protein-coding genes started with a traditional ATG codon except for COX1, COX2, and ND3, which initiated with non-typical start codon GTG, GTG, and ATA instead, respectively, and terminated with the mitochondria stop codon (TAA/TCC/AGG/AGA). The mitogenome structural organization was identical to the same genus species Phaethon rubricauda. The overall AT content was 52.04%, which was higher than GC. To obtain the phylogenetic status of Phaethon lepturus, we constructed the species phylogenetic tree together with the 12 protein-coding genes of nine other closely species. We expected that the complete mitogenome of while-tailed tropicbird would contribute to address taxonomic issues and study the related evolution events.
