Ablabesmyia jogancornua Sasa et Okazawa, 1991: 64 .

Ablabesmyia (Ablabesmyia) jogancornua: Niitsuma 2013: 492 .

Material examined. 1 male with pupal exuviae, CHINA: Hubei Province, Shiyan City, Mt. Wudang, Lake Tian , 24.vi.2017 ; 1 male, Anhui Province, Huangshan City, Tangkou Town, Huangshan Nature Conservation Reserve , Fuxi Stream, 27.v.2012 ; 1 male, Fujian Province, Minqing County, Huangchulin National Nature Reserve , 9.xi.2012 ; 1 male, Yunnan Province, Anning City, Qinglongxia Nature Reserve , Shuishenqiao, 27.iv.2017 ; 1 male with pupal exuviae, 1 pupal exuviae, Yunnan Province, Honghe Hani and Yi Autonomous Prefecture , Pingbian Miao Autonomous County, Daweishan National Nature Reserve , stream, 4.vi.2017 .

Remarks. The species has been known only from Palaearctic Japan ( Sasa & Okazawa 1991, Niitsuma 2013). Here, we record the distribution in Oriental (Fujian and Yunnan Provinces) and Palaearctic (Hubei and Anhui Provinces) China, based on the male specimens possessing a dorsal lobe with an apical brush, a curved blade with a pointed apex, and a lateral lobe with apicomedial serration in the aedeagal complex ( Fig. 2B ), and the pupal specimens possessing darkened pattern on the abdominal tergites II–VIII (Niitsuma 2 0 13, figs 42a, b). The adult somewhat resembles that of A. (A.) amamisimplex in the general appearance but can be easily separated by the number of spots along the anterior costal margin, which is three in A. (A.) jogancornua , and two in A. (A.) amamisimplex ( Niitsuma 2013) .
