Abstract:

Objective　To determine the species distribution and taxonomy of Culicoides (Sinocoides) in China. Methods　 Bed nets, light traps and insect nets were used to collect the subjects. Results　Eight species of Culicoides (Sinocoides) have been recorded in China, including Culicoides (Sinocoides) malipoensis Liu et Ren, sp. nov. and Culicoides (Sinocoides) nanniwanensis Liu et Wang, sp. nov. The distribution of the known species in China and measurements of the main differential characteristics were described to compile a key list of species. Conclusion　The investigation clarified the distribution and composition of Culicoides (Sinocoides) in China.
Culicoides (Sinocoides) malipoensis Liu et Ren, sp. nov. is alike to Culicoides subpalpifier Wirth et Hubert, 1989. The latter is noticeably distinguishable by contiguous eyes, palpal ratio (PR) of 2.5 and unequal spermathecae of 3. Culicoides (Sinocoides) nanniwanensis Liu et Wang, sp. nov. is alike to Culicoides opertus Liu et Yu, 1990, but the latter is distinctly characterized by the absence of sensory pits on the third palpus, absence of sensilla coeloconica in the 15th antenna segment, and wings with two pale spots. The type specimens are preserved in the Center for Disease Control and Prevention of Shenyang PLA Command, Shenyang 110034, China.
