Anopheles stephensi Liston 1901 is a primary mosquito vector of malaria in urban India and is included in the same subgenus as Anopheles gambiae, the primary malaria vector in Africa.[1] A. gambiae consists of a complex of morphologically identical species of mosquitoes, along with all other major malaria vectors, however, A. stephensi has not yet been included in any of these complexes.[2] Nevertheless, two races of A. stephensi exist based on differences in egg dimensions and the number of ridges on the eggs: A. stephensi stephensi sensu stricto, the type form, is a competent malaria vector that takes place in urban areas, and A. stephensi mysorensis, the variety form, exists in rural areas and exhibits considerable zoophilic behaviour, making it a a poor malaria vector.[3] However, A. stephensi mysorensis is a detrimental vector in Iran.[4] An intermediate form also exists in rural communities and peri-urban areas, though its vector status is unknown.[4]
About 12% of malaria cases that occur annually within urban areas of India are due to A. stephensi.[5]
