(2) Nematopogon distinctus Yasuda, 1957

(Plates I-1, XII-1, XXI-1, XXXI-4)

Nematopogon distincta Yasuda, 1957: 38 , fig. 1 (TL: Japan, Honsẙ [Honsyu], near Osaka); Park 1983: 107.

Nematopogon distinctus: Asano 2012: 117 (list of Nagoya University); Hirowatari 2013: 103, fig. 3-07-5,6 ( Japan); Umetsu 2014: 4, fig. 2 ( Japan, Akita Prefecture).

Diagnosis. This species is very similar to N. taiwanella but can be distinguished by the pointed tip of the valva, pectinifer with ca. 45 pegs, and aedeagus apex with a curved hook and a pair of curved barb-shaped cornuti dorsolaterally.

Specimens examined. [Hunan] 3♁ 1♀, Jintongshan National Nature Reserve, Nanshan National Park, Chengbu Miao Autonomous County, Shaoyang City, 2021.V.20, C.Q. Liao leg.; 1♀, Jintongshan National Nature Reserve, Nanshan National Park , Chengbu Miao Autonomous County, Shaoyang City , 2020.V.07, C.Q. Liao leg. ; [Guangdong] 1♁, Nankunshan National Forest Park, Longmen County, Huizhou City , 2004.III.30, G.H. Huang leg. ; [Guangxi] 1♁, Maoershan National Nature Reserve (1,500 m), Xing’an County, Guilin City, 2010.V.25–26, G.H. Huang leg. ( HUNAU) .

Distribution. China (new record: Hunan, Guangdong, Guangxi); Japan, Korea.

Remarks. This species was previously reported in Japan and Korea before ( Yasuda 1957; Park 1983; Asano 2012; Hirowatari 2013; Umetsu 2014), and is now distributed in the Nanling Mountain system as a newly reported species from China in this study. This species is attracted by light traps at midnight (Plate XXXI-4).

One DNA barcode of Nematopogon distinctus is sequenced and shows 0.084 –0.086 pairwise distances from three N. stenochlora specimens. Phylogenetic analysis shows that N. distinctus did not appear to the clade with all other Nematopogon species, but as an independent clade, although the bootstrap value was less than 50%.
