Abstract: We reported a new species of the subgenus Stegomyia in the genus Aedes, Aedes (Stegomyia) mengduiensis sp. nov., collected from a discarded tyre near the government offices of Mengdui Township in Zhenkang County, Yunnan Province, China (98°53'31″E, 23°55'9″N) in February 2017. The main features of the new species include: incomplete white basal bands on the dorsal plate of the abdominal segments Ⅲ-Ⅵ; the white basal ring of tarsus 4 of the hind leg accounting for more than 3/4 of the total length of tarsus 4; female postgenital lobe with a posterior process at the median apex; males featuring a thick distimere with a marked enlargement at the apex and a claspette with a fan-shaped enlargement at the apex and numerous leaf-like spines and bristles. The morphology of the larvae is not significantly different from that of Ae. albopictus larvae. The type specimens were preserved in the museum of mosquito of Yunnan institute of parasitic diseases.
