构成冈比亚按蚊复合体的六种非洲热带蚊子包括世界上最有效的疟疾病媒以及一种非病媒蚊子。对这些物种之间的进化关系的公认解释是基于染色体倒置，并表明两个主要载体，冈比亚疟蚊和阿拉伯按蚊，位于系统发育树的遥远分支上。然而，DNA序列数据表明这两个物种是姐妹分类群，并表明它们之间存在基因流动。这些结果对以非媒介种群替代媒介种群的疟疾控制策略具有重要意义。
The six Afrotropical species of mosquitoes comprising the Anopheles gambiae complex include the most efficient vectors of malaria in the world as well as a nonvector species. The accepted interpretation of evolutionary relationships among these species is based on chromosomal inversions and suggests that the two principal vectors, A. gambiae and Anopheles arabiensis, are on distant branches of the phylogenetic tree. However, DNA sequence data indicate that these two species are sister taxa and suggest gene flow between them. These results have important implications for malaria control strategies involving the replacement of vector with nonvector populations.
