Nemotois chalcophyllis Meyrick, 1935: 96 (LT: China, Chekiang [Zhejiang], West-Tien-Mu-Shan [Mt. Tianmushan]). Nematopogon chalcophyllis: Nielsen 1985: 35 ; Wu & Pan 2001: 535 (list); Hua 2005: 2 (list of China).

Diagnosis. This species differs from the closely related species N. taiwanella primarily in the genital structures, including valvar pectinifer with fewer than 30 pegs, uncus with convex lateral margins, aedeagus with two cornuti, and juxta with a wide round arrow-head. Moreover, this species can also be distinguished by the female genitalia with a relatively wide tergite VIII (about 2.5 × as long as wide) and a prominent medial lobe in the hind margin.

Specimens examined. Not available in this study.

Distribution. China (Zhejiang).

Remarks. This species is endemic to China and is only known from the type locality (Zhejiang, Mt.Tianmushan) ( Nielsen 1985; Kozlov 2001).
