An. fluviatilis now is a comlex comprising four sibling species, S, T, U and new species V. Recently, based on the homology of D3 domain of 28S rDNA, Harbach (2004), Garros, Harbach & Manguin (2005) and Chen et al. (2006) considered An. fluviatilis S conspecific with An. minimus C. Consequently, Harbach (2004) removed An. fluviatilis S from the Fluviatilis Complex in his taxonomic update. Furthermore, all these authors said that the Fluviatilis Complex consists of only two sibling species, species T and U.
