Neochauliodes nigris Liu & Yang, 2005a . Zootaxa 1045: 17. Type locality: Guizhou (Fanjingshan, Leigongshan, Shiqian, Duyun, Huaxi, Liping), Fujian (Wuyishan), Jiangxi (Jiulianshan), Guangxi (Guilin), Hunan (Liuyang, Mangshan), Zhejiang (Longquan).

Specimens examined. JAPAN: ♂, Ryukyus : Iriomote Island, Takana River, reared and emerged in 6. V .1989, F. Hayashi ( CAU) ; 2 ♀, Ryukyus : Iriomote Island, Takana River, 23/ 26.IV.1988, F. Hayashi ( CAU) ; ♂, Ryukyus : Iriomote Island, Urauchi –gawa, 11. V .2000 (HC); 1 ♀, Ryukyus : Iriomote Island, Otomi, 24.IV.2004 (HC) ; ♂, Ryukyus : Ishigaki Island, Nagura River, 30.IV.1997, K. Tojo ( CAU) .

Distribution. China (Guizhou, Hunan, Jiangxi, Zhejiang, Fujian, Guangxi); Japan (Ishigaki and Iriomote Islands).

Remarks. Kuwayama (1964) firstly recorded this species from Ishigaki Island, Japan, and he identified it as N. sinensis . Hayashi (1989b) also recorded N. sinensis from Iriomote Island neighboring to Ishigaki Island. However, this species distinctly differs from N. sinensis by the wing patterns and the male tenth sternum with the apex strongly inflated in lateral view. In N. sinensis , the median transverse band on the forewing is long and narrow, and the apex of the male tenth sternum is not inflated. The prothorax in N. nigris from the Ishigaki and Iriomote Islands is bright yellow, while it is a little dull and marked with a pair of brownish vittae on the lateral margins in that from the Chinese mainland.
