Evidence of cryptic genetic lineages within Aedes notoscriptus (Skuse)

Abstract

Aedes notoscriptus (Skuse), a mosquito from the southwest Pacific region including Australia, has been implicated as a vector of arboviruses, but its status as a species is unclear. To investigate the taxonomic situation, we assessed genetic variation and phylogenetic relationships among Ae. notoscriptus from the east coast of Australia, Western Australia and New Zealand. Phylogenetic analyses of DNA sequence data from mitochondrial markers indicate that Ae. notoscriptus is a complex of divergent genetic lineages, some of which appear geographically restricted, while others are widespread in eastern Australia. Samples from New Zealand and Western Australia were related to populations from on..
