Abstract:

Two new species of the Culicoides(Oecacta), C.(O.) mengyuanensis sp. nov.,and C.(O.) sublini sp. nov. are described from Yunnan and Tibet in China. C.(O.) mengyuanensis sp. nov. is somewhat allied to C.(O.) yadongensis Chu, 1977 in the eyes and buccal armature, but is distinctly different from antenna sensilla coeloconica present on segments 3, 11-15, antennal ratio(AR)1.04 of female C.(O.) yadongensis Chu, 1977. C.(O.) sublini sp. nov. is similar to C.(O.) lini Kitaoka et Tanaka, 1985, both are distinctly different in the small-sized species(wing length 0.93 mm), eyes with interfacetal hairs, wing base portion with a pale spot, and contiguity with a pale spot in basal portion of Anal cell; wing with a pale spot over basal potion half of R1 cell and r-m cross-vein, and separated with a pale spot in middle potion of M2 cell of female C. lini Kitaoka et Tanaka, 1985. The type specimens are deposited in the Shenyang Command Center for Disease Control and Prevention (Shenyang 110034).
