[A new culicid in Italy: Aedes (Ochlerotatus) annulipes (Diptera, Culicidae)].

The first italian record of Aedes annulipes is described. The species was collected in various sites of the eastern Po-Venetian valley (North-eastern Italy), from sea level up to 190 m a.s.l. The larval breeding sites were seasonal fresh water marshes within woods. Preimaginal development took place from February to May. Ae. annulipes was univoltine with a possible second minor generation. The females were strongly anthropophilic. Main morphological data are provided and compared with those of the close species Ae. cantans. The adaptation to environments south of Alps and even at sea level by a northern palearctic element such as Ae. annulipes is presumably achieved by the exploitation of sufficiently cold biotopes available for larval breeding during the winter-spring period.
