Forcipomyia (Forcipomyia) makanensis Hou sp. n. (Diptera: Ceratopogonidae) is described and illustrated based on male and female specimens from China. It is characterized by the male aedeagus triangular, with large cone-shaped process at apex, basal arch high, basal arm slender and curved, parameres separate narrower distance at base, cone-shaped apically, and the female subgenital plate pliers-shaped, without lateral process, with two spermathecae, oval, nearly equal. The new species is compared with the similar congener F. (Forcipomyia) lochmocola Zou and Yu, 1991. We provide separate keys for identification of the males and females of the species of subgenus F. (Forcipomyia) Meigen in China.
