Abstract: This article reports 23 species of hematophagous midges belonging to 2 genera in Wenchang city, Danzhou city, and Chengmai county of Hainan province, China in 2017, among which there were 22 species of Culicoides and 1 species of Lasiohelea. A new species of C. danzhouensis Liu et Liang, sp. nov. was found, and C. pangkorensis Wirth et Hubert, 1989 was a new record in China. The species of C. calcaratus Wirth et Hubert, 1989 was recorded for the first time in Hainan province. There were 17 species in Wenchang, 18 species in Danzhou, and 19 species in Chengmai. C. danzhouensis Liu et Liang sp. nov. had similar wings as C. recurvus Delfinado, 1961, but the latter had shorter palpus, with a palpus ratio of 2.2; male C. recurvus had narrow parameres, no horn process outside the near middle area, a papillae minute at the middle area of the rear edge of the ninth tergum, and no microtrichia on the ventral membrane of the ninth sternum, which were significantly different from C. danzhouensis Liu et Liang sp. nov. C. danzhouensis Liu et Liang sp. nov. had similar male terminalia as C. lushuiensis Liu et Feng, 2018, but there were significant differences in the numbers and shapes of pale spots on wings between the two species; the latter had no microtrichia on the ventral membrane of the ninth sternum, with aedeagus basal arch extending to nearly one-fifth of total length, which were significantly different from C. danzhouensis Liu et Liang sp. nov. The model specimen of the new species was deposited in the North Command Center for Disease Control and Prevention (Shenyang 110034)
