(Plates IX-1, 2, XX-2)

Nemophora biprocessa Sun, Wang & Li, 2022: 307 , figs. 6, 31 (TL: China, Jiangsu, Mt. Baohua ; NKU).

Diagnosis. This species is very similar to N. chalybeella and N. lapikella but can be distinguished by the triangular median process of the transtilla, and by the phallus with two narrow processes and a banded process ( Sun et al. 2022).

Specimens examined. [Jiangsu] 3♁ 2♀, Xianlin Campus, Nanjing Normal University, Nanjin City , 2021.IV.7, Q. Shi leg.; [Hunan] 4 ♁ 2♀, Shuangjiangkou, Jintongshan National Nature Reserve , Chengbu Miao Autonomous County, Shaoyang City , 2020.V.7, C.Q. Liao leg.; [Guangxi] 1 ♁ 2♀, Maoershan National Nature Reserve, Guilin City , 2017.V.1–5, L.S. Chen leg. ( HUNAU) .

Distribution. China (Jiangsu, Hunan, Guangxi).

Remarks. This species was described by Sun et al. (2022) based on a single male specimen collected from Mt. Baohua, Jiangsu, China. We also collected this species in Jiangsu, Hunan, and Guangxi Provinces, including male and female adults. The forewing pattern of specimens from Hunan and Guangxi showed some differences from that of specimens from the type locality: both sides of the forewing central fasciae are inwardly concaved, nearly Xshaped in the type locality’s specimens, while nearly wavy in populations of Hunan and Guangxi; and the subapical radial striae are long, extending near the apex of the forewing in type locality’s specimens, but relatively short and extending to half of the subapical area in populations of Hunan and Guangxi (Plate IX-1, 2).

Three DNA barcodes of different N. biprocessa populations from Hunan are generated, which showed relatively large intraspecific genetic distances (pairwise distances: 0.006 –0.028) .
