Anopheles stephensi: Anopheles stephensi 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.  "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.  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 poor malaria vector.  However, "A. stephensi mysorensis" is a detrimental vector in Iran.  An intermediate form also exists in rural communities and peri-urban areas, though its vector status is unknown.
