BELTRAN-AGUILAR, Adriana et al. Taxonomy and distribution of the anopheline mosquitoes in the state of Veracruz, Mexico (Diptera: Culicidae, Anophelinae). Acta Zool. Mex [online]. 2011, vol.27, n.3, pp.601-755. ISSN 2448-8445.

Malaria is a human disease caused by four species of the protozoon genus Plasmodium which are transmitted by Anophelinae female mosquitoes of some species of the genus Anopheles. It has been estimated that in Mexico 33.1% of the human population lives in areas where the transmission of malaria is possible. The risk area includes the State of Veracruz that has been a traditional endemic zone in the past. Factors as weather, human density and human migration elevate the potential transmission risk. In this study, basic information needed for the reactivation of the entomological surveillance in the Veracruz State is provided, presenting the check-list with the illustrated diagnosis of larva, pupa, adult male and female, and taxonomic keys for the identification of species based in all postembryonic developmental stages. The known and potential distribution maps were obtained using GARP. Some bionomic data and the medical importance of the species are also mentioned. There are 18 Anophelinae species in Veracruz, grouped in two genera, Chagasia with one species and Anopheles with 17, pertaining to three subgenera An. (Anopheles), An (Kerteszia) and An. (Nyssorhynchus). According to the plasmodium transmission capability and distribution range, four groups of species are recognized: the high risk group, with 2 species; the median risk or regional risk group, with 8 species; the low risk group, with 3 species and the no risk group with 5 species. Potential malaria vectors are present throughout almost the entire state, so permanent surveillance of the anopheline populations must be reestablished. This study contributes strong elements for the future certification of the Veracruz State as an area free from malaria.
