Abstract: The biting midges (in the family Ceratopogonidae) in various habitats in Nanchang city, Jiangxi province, China were investigated from 2008 to 2010, and a new species of the subgenus Forcipomyia of biting midges was found by identifying the collected samples. The new species was Forcipomyia (Forcipomyia) hongdouensis Yu, Liu et Chen, sp. nov., named after Hongdu park, Qingyunpu town, Nanchang city, where its samples were collected. The specimens of the new species were deposited in the Medical Entomology Collection Gallery, Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences (20 Dongda Street, Fengtai District, Beijing 100071). Forcipomyia (Forcipomyia) hongdouensis Yu and Liu sp. nov. (Figure 1) Diagnosis: Male: of large size; compound eyes bare, and the 3rd segment of palpus slender and with a light sensory pit; the distal 4th segment of flagellomere elongated, and the 12th segment longest; legs pale yellow without any spot; TR<1, hind tibia with 8 terminal bristles, and 13 comb teeth; aedeagus long shield-like and paramere X-shaped. Wing length 1.64 mm, width 0.41 mm; TR<1, TR(Ⅰ) 0.58, TR(Ⅱ) 0.31, TR(Ⅲ) 0.37. F-T(Ⅰ) 96:101:28:48:30:22:15, F-T(Ⅱ) 108:118:20:64:33:22:15,F-T(Ⅲ) 110:123:26:70:36:26:15. This new species has a highly distinctive palpus different from that of other species of the subgenus Forcipomyia, because of its light sensory pit. But it resembles to F.(F.) fuliginosa (Meigen), 1818 and F.(F.) intosa (Chan and LeRoux,1971) in the structure of the genitalia; it is also similar to the F.(F.) striaticornis (Kieffer),1902, in the structures of the aedeagus and paramere, but is distinguished by the light branch of aedeagus. Holotype: Male (♂). 2010-10-28, collected from Hongdu park, Qingyunpu town, Nanchang city, Jiangxi province, China. Deposited in the Medical Entomology Collection Gallery, Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences (20 Dongda Street, Fengtai District, Beijing 100071). Female: Unknown.
