is a major vector of malaria in Africa. It belongs to a group of sibling species that can be identified morphologically only at certain stages of their development. A diagnostic polymerase chain reaction (PCR)-based tool made it possible to differentiate five species of the group. The assay seems to be applicable over all their distribution area for four of these species: and The fifth species, is the second most abundant species of the group and can be mistaken at its adult stage for the major vector of malaria Molecular and morphologic observations of specimens identified as from Cameroon and South Africa showed that they belong to two different taxa. The species identified in Cameroon, and named here -like, might extend to western Africa and central Africa. The species-specific PCR assay is supplemented by a primer specific to -like and thus makes it possible to differentiate the five species of the group and the newly defined taxon.
