Abstract
The complete mitogenome sequence of the flea, Ceratophyllus wui (Siphonaptera: Ceratophyllidae), was sequenced. The 18,081 bp long genome has the standard metazoan complement of 37 genes. These genes contain 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and one control region. The nucleotide composition of the C. wui mitogenome was A: 37.72%, T: 38.99%, G: 9.51% and C: 13.78%. The A + T content is 76.71%, showing strong AT skew. Phylogenetic analysis indicated that Siphonapteran has sister relationship with Dipteran.
