Description of a new species of Forcipomyia (Lasiohelea) (Diptera: Ceratopogonidae) and a key to species of the F. (L.) taiwana species group in China

Forcipomyia (Lasiohelea) (Meigen, Diptera: Ceratopogonidae) penguin sp. nov. is described and illustrated based on male specimens from China. It is characterized by the approximately rectangular aedeagus, which is longitudinally split in the middle, with the apices slightly bending to the outside, making it into the shape of a hook; bilobed aedeagus is very closely connected. The description is provided using scanning electron microscopes, light microscopes, and camera lucida drawing. The specimens were collected from woods near a pond in Liping County, Guizhou Province. We provide both keys to male and female of Forcipomyia (Lasiohelea) taiwana species group in China.
