Abstract: Anopheles longipalpis (Theobald) (Diptera: Culicidae) is a predominantly zoophilic mosquito that has not been implicated in malaria transmission. However, this species was collected indoors with An. funestus s.l. in southern Zambia, where transmission of Plasmodium falciparum is hyperendemic, and we initially misidentified it morphologically and molecularly as An. funestus s.l. The indoor resting density and blood-feeding behaviour of An. longipalpis were investigated during the 2004-05 and 2005-06 transmission seasons in Mufwafwi village in southern Zambia. Numbers of endophilic An. longipalpis increased towards the end of the rainy season. Although specimens were collected during human landing catches, the feeding behaviour of An. longipalpis was significantly biased towards cattle (88.7%), with other bloodmeals originating from dogs, goats and chickens. None of the 177 specimens of An. longipalpis were infected with P. falciparum. These data are consistent with existing reports that An. longipalpis is not involved in malaria transmission. However, more extensive sampling is necessary. Importantly, the correct identification of An. longipalpis is crucial for malaria control programmes in areas where An. funestus s.l and An. longipalpis exist sympatrically so that scarce resources are not wasted on the control of a non-vector.
