Intraspecific vs. interspecific distance of COI sequence from Cx. annulirostris,Cx. palpalis and Cx. sitiens. (A) Morphological taxa maximum intraspecific distance was compared to the minimum interspecific congeneric difference (Kimura 2 distance). (B) The morphological taxa were divided into several proposed lineages and their maximum intra-lineage distance was compared to the minimum inter-lineage difference. For both graphs the 3% threshold is highlighted, dividing the graph into four quadrants that represent different categories of "species" [15]: top left – species concordant with current taxonomy; top right – probable composite species, i.e. candidates for taxonomic split; bottom left – species that have undergone recent divergence, hybridization, or synonymy; bottom right – probable specimen misidentification.
