[Description of a new Aedes of the subgenus Ochlerotatus (Diptera: Culicidae) from Madagascar: Aedes ambreensis n.sp. and general observations on the females of the subgenus Ochlerotatus in the Afro-tropical region].

The authors describe the female of a new malagasy Aedes species belonging to the sub-genus Ochlerotatus, collected during epidemiological surveys on arboviroses: Ae. ambreensis n. sp. With this description, a review of Afro-tropical Ochlerotatus species is proposed, particularly on principal morphological female characters and geographical distributions. A key for identification of afro-tropical adult females of the sub-genus Ochlerotatus is annexed.
