A new species of the genus Culicoides,C. liweiaesp. nov. from Luobei port, Heilongjiang province, China is reported.The new species is closely allied to maleC. gornostaevae Mirzaeva, 1984, but what is distinctly different between them is that the latter is pale in the distal half of cell R2 with a nearly triangle pale spot in the distal portion of cell R wing, no mocrotrichia in the basal cell of wing, the ventra root of two lateral basistly not continuous, and the ninth sternum in"V"caudomedion excavation.The ninth sternum of the male of this new species is also similar to that ofC. sinanoensisTokunaga, 1937, but they are distinctly different in the shapes of ventra root basistly, ninth tergum, and aedeagus.C. filicinusGornostaevaetGachegova, 1972 (♀) is recorded for the first time in China. The type specimen is deposited in the Entomology Collection Gallection Gallery of Heilongjiang Entry-Exit Inspection and Quarantine Brueau of the P. R. China (Haerbin 150001, China).
