Fig 2. Mitochondrial Maximum likelihood phylogeny.

Twenty-four different mitochondrial haplotypes (Hap1-24) found in Aedes aegypti type and var. queenslandensis that co-occur in Singapore and northern Queensland, Australia. Sequences of the three outgroups (Ae. albopictus, Ae. vigilax, Ae. notoscriptus) and Ae. aegypti Liverpool strain were obtained from the NCBI nucleotide sequence/genome database, with the NCBI accession numbers listed in square brackets. The number of Ae. aegypti individuals with a given mitochondrial haplotype is listed in parentheses. A circle designates haplotypes found in Queensland, and a triangle those found in Singapore. Open symbols designate haplotypes found in the queenslandensis form, and filled symbols those found in the type form.
