  abstract = {#{A}nopheles gambiae$ and #{A}n. arabiensis$ are mosquito species responsible for most malaria transmission in sub-{S}aharan {A}frica. {T}hey are also closely related sibling species that share chromosomal and molecular polymorphisms as a consequence of incomplete lineage sorting or introgressive hybridization. {T}o help resolve these processes, this study examined the partitioning of mt{DNA} sequence variation within and between species across {A}frica, from both population genetic and phylogeographic perspectives. {B}ased on partial gene sequences from the cytochrome b, {ND}1 and {ND}5 genes, haplotype diversity was high but sequences were very closely related. {W}ithin species, little or no population subdivision was detected, and there was no evidence for isolation by distance. {B}etween species, there were no fixed nucleotide differences, a high proportion of shared polymorphisms, and eight haplotypes in common over distances as great as 6000 km. {O}nly one of 16 shared polymorphisms led to an amino acid difference, and there was no compelling evidence for nonneutral variation. {P}arsimony networks constructed of haplotypes from both species revealed no correspondence of haplotype with either geography or taxonomy. {T}his trend of low intraspecific genetic divergence is consistent with evidence from allozyme and microsatellite data and is interpreted in terms of both extensive gene flow and recent range expansion from relatively large, stable populations. {W}e argue that retention of ancestral polymorphisms is a plausible but insufficient explanation for low interspecific genetic divergence, and that extensive hybridization is a contributing factor.
