( Figs. 7 , 13 )

Anoplophora cheni Bi & N. Ohbayashi, 2015: 294 , figs. 4a, 4b, 6, 8. Type locality: Yunnan, China.

Anoplophora cheni: Lin & Yang, 2019: 294 .

Type material examined. Holotype. female, “ CHINA. Yunnan, Jinping, Fenshuiling , 1,870 m, 2009.V.26, leg. Wen-Xuan Bi ” ( CBWX).

Other material examined. 1 female, China, Guizhou, Jiangkou, Fanjingshan , 1,775 m, 2016.VII.23, leg. Yu-Tang Wang ( CCCC) ; 1 male, Guizhou, Leishan, Leigongshan , 2,400 m, 2016.VIII.14, leg. Zhong-Liang Jiang ( CCCC) ; 1 male, Vietnam, Yên Bái Prov. 2015.V, local collector ( CBWX) .

Complementary description. Male ( Fig. 7 ). Body length 20.1–21.5 mm, humeral width 7.4–7.9 mm. General appearance similar to the female described by Bi & N. Ohbayashi (2015). Body slightly slenderer. Antenna about 1.7 times of body length. Legs relatively longer and thicker. The scale-like pubescence on body, elytra and appendages colored with pale or yellowish. One individual from Leishan, Guizhou has the elytral anteromedian band separated into two transverse narrow strips and subapical transverse band interrupted near suture.

Endophallus in everted condition ( Fig. 13 ) moderately long, about 3.9 times as long as median lobe; relative lengths of APH: MPH: BPH: PB: CT: MT = 1.0: 1.4: 0.3: 0.2: 0.5: 0.8.

BPH curved dorsally before middle; subdivided into MT, CT and PB by constrictions; MT evenly cylindrical or weakly swollen near apex; CT cylindrical, with lateral to ventral surface covered with minute spicules at base; PB with anterior bulb moderately developed. APH with apical bulb (ab) slightly shorter than apical bubble (bb); apical bulb moderately sclerotized, elongate and subcylindrical; surface with microspinules arranged in distinct transverse rows, which are getting denser apically; bb apically provided with a pair of rod-like sclerite which is slightly longer than half the length of ab.

Distribution. China: Yunnan; Guizhou (new Province record), Vietnam (new Country record): Yên Bái.

Remarks. Color of scale-like pubescence of two studied male specimens on body, appendages and elytra are pale or yellowish, instead of turquoise on the female holotype. This inconsistent situation would be color fading caused by suboptimal preservation of the specimen. Such kind of color fading also has been observed in Anoplophora multimaculata ( Xie & Wang, 2015) collected from Zhejiang.

The endophallic structure of this species similar to Anoplophora wusheana Chang, 1960 ; A. quadrifasciatus (Bi & N. Ohbayashi 2015, Figs. 9–10 ) and A. multimaculata ( Fig. 14 ), but can be distinguished by medial tube (MT) lacking apical swelling.
