Resumo: A literature analysis coupled with new entomological surveys conducted between 2009 - 2012 led to changes in the list of mosquito species present on the isl- of La Réunion. Using morphological criteria, Orthopodomyia arboricollis is replaced by Or. reunionensis. On the basis of morphometrical - genetic criteria, Culex univittatus is replaced by Cx. neavei. Cx. poicilipes, which was already reported missing 40 years ago, has not been found again. Anopheles arabiensis is confirmed as the only species of the Gambiae complex present on the isl-. Thus, twelve species are currently known. For each of them, elements of taxonomic, biological - medical interest are listed. An. arabiensis is a major vector of human Plasmodium (last case of indigenous malaria in 1967). In the Indian Ocean, Aedes albopictus - Ae. aegypti both are competent for transmitting dengue - chikungunya viruses. In Africa, Cx. quinquefasciatus transmits Wuchereria bancrofti - Cx. neavei transmits the Sindbis virus; both species also transmit the West Nile virus. Cx. tritaeniorhynchus is the major vector of Japanese Encephalitis virus in Asia. Two species are endemic (Ae. dufouri - Or. reunionensis), the ten other ones are also found in Madagascar - on the African continent (An. coustani, An. arabiensis, Ae. fowleri, Cx. tritaeniorhynchus, Cx. neavei, Cx. insignis, Lutzia tigripes), with three of them having also a cosmopolitan distribution (Ae. aegypti, Ae. albopictus - Cx. quinquefasciatus). Among the twelve recorded taxa, eight species are anthropophilic, three are supposedly zoophilic - one is a predatory species. No new invasive anthropophilic species did settle on the isl-. Updated identification keys of larval - adult stages are proposed.
