Abstract:

Objective To determine the species of hematophagous midges in Luobei county, Heilongjiang province, China.Methods Light traps and insect nets were used to capture the midges. Results A total of 26 827 bloodsucking midges (30 species, one genus) were captured in Luobei county from 2009 to 2013. A new species of the genus Culicoides, C. luobeiensis Liang et Liu, sp. nov., was reported. The new species was closely allied to C. subcircumscriptus Yu, 1982, but C. subcircumscriptus Yu, 1982 had the following distinct differences: presence of little pale spots on cell R5 and the distal portion of vena M1; in females, presence of sensilla coeloconica on segments 3, 11-14; in males, presence of spiculae on the ventral membrane of the ninth sternum, stout apicolateral processes on the ninth tergum, absence of the ventral root of basistyle, and absence of small pricks inside the paramere bases. C. alazanicus Dzhafarov, 1961 (♀) was recorded for the first time in China. Conclusion This investigation provides a basis for further study on the species distribution of hematophagous midges in Luobei county, Heilongjiang province. The type specimens are deposited in the Shenyang Military Command Center for Disease Control and Prevention (Shenyang 110034, China).
