During an entomological survey conducted in French Territory of Afars and Issas from november 1973 to june 1975, the following species were collected: Aedes caspius, A. vittatus, Culiseta longeareolata, Uranotaenia balfouri, Mimomyia mimomyiaformis, M. mediolineata. To these mosquitoes, we must add the record of A. aegypti larvae on a dhow berthing in Djibuti while this mosquito does not exist actually in the Territory. The epidemiological importance of these culicids is discussed.
