Unfortunately, after the publication of our work [1], we noticed a typo and a mistake in Fig. 2. In Fig. 2, two genes were both labelled with the same abbreviation (ND1); these should have been labelled as ND1 (between COII and GR3) and ND2 (between GR3 and ATPase6). In addition, the orientation of ATPase6 should have been the same as Cyb.
