Material examined. CHINA: 7ɗ, Mt. Jiajin, 4000–4100m, 102°85'E, 30°38'N, Sichuan Province, 4.viii.2005 (Ming-fu Wang) ( SYNU).

Remarks. The orginal description of this species is not clarity and exact (e.g., frons width, arista and the longest hairs of it, wing etc.). Therefore, it is needed to be redescriptied. By compared terminalia and habitus with original figures and description of the species, it is sure that the specimens are Botanophila nigribella ( Deng, Geng, Liu & Li, 1995) .

Geographic distribution. China.
