In D3 gene with 5 site mutations. There exists individual variation in the COII gene, but this variation is less than that among other members of Myzomyia Series such as An. aconitus, An. jeyporiensis, etc. In addition, one haplotype different from both An. minimus A and C was found in these 3 genes studied.②The genetic distance between An. minimus A and An. minimus C is less than that among other members of Myzomyia Series. Molecular trees based on different genes and different methods show that An.

种系发生研究表明，微小按蚊复合体亲缘种A、C间的遗传距离远小于与之近缘的同系其它成员间的距离。2个分子标记3种方法构建的基因树显示，微小按蚊A、C的种系地位非常固定，不同地域来源、不同变异类型的微小按蚊始终在同一分&枝&上，与迈蚊系其它成员相比，呈现其相对稳固的单源性。
