Supplementary description. For descriptions, see paper by Lin et al. (2006), genitalia are described in more detail herein. Male genitalia ( Figs. 57–61 ): Tergite VIII ( Figs. 57 a, 57c) as broad as long, apex rounded, with setae which are moderate long at sides, and shorter but not sparser at middle. Spiculum gastrale subequal to length of ringed part of tegmen, spiculum relictum shorter than a half-length of spiculum gastrale. Tegmen ( Figs. 58 a–d) about 2.8 mm in length; lateral lobes stout, each about 0.5 mm long and 0.2 mm wide; apex with fine setae longer than half of lateral lobes; median lobe slightly curved ( Fig. 59 b) in lateral view, slightly longer than tegmen (15:14); median struts subequal to half-length of median lobe ( Fig. 59 c); apex of ventral plate ( Fig. 59 a) pointed; endophallus with triple length of median lobe, with four pieces of basal plate-like sclerites (located behind apex of median struts), two bands of supporting armature, and three rod-like sclerites at end ( Fig. 60 ), which are about 2.2 mm, much shorter than tegmen. Female genitalia: spermathecal capsule ( Fig. 62 ) composed of an apical orb and a short but strongly curved stalk. Spiculum ventrale longer than abdomen. In our observation, spiculum ventrale measured 8.0 mm for an adult compared with abdomen which measured 7.2 mm in ventral view.

Remarks. The type locality was reported as “environs de Péking ” ( Pic 1939) and simply treated as Beijing ( Lin et al. 2006). However, the “ Trappe ” written on the label ( Fig. 1 in Lin et al. 2006) was ignored. In the “ Etapes des Voyages du P. Licent (1914–1937)”, under the year 1930, “ 7 VI la Trappe (2 journées 1/2 à l’ouest de Péking ” was explained as “ Yangjiaping (Hebei, SE. Huailai County) ; “ 21 VI Retour à la Trappe ” was explained as “return to Yangjiaping ”; under the June of 1931, Licent’s records including “ 1 VI Kao kia yingze” (NE. Zhangjiakou), “ 12 VI Kalgan” (Zhangjiakou), “ 13 VI Tien tsin” ( Tianjin), “ 26 VI Takou (en bateau)”, “ 27 VI Tcheu fou” (Qufu, Yantai), “ 30 VI ile des Français (Excur.)” Therefore, the “ Trappe ” indicates that the type locality should be Yangjiaping, which is located west of Beijing, belonging to Hebei Province, Zhuolu County, which is part of Xiaowutaishan Nature Reserve, and the date of collection should between 2 June 1931 to 13 June 1931. Two females from the exact type locality “Yangjiaping” were examined for this study.

Two specimens from Liaoning, Jinzhou were reported by Wang (2003: 329) as Monochamus bimaculatus , and they were reported again by Wang (2014: 832) as Monochamus bimaculatus and mislabeled the female as “ Guangxi, Liuzhou”. Obviously they are same pair of specimens and Liaoning is the probable locality.

Host Plant: Populus sp. ( Salicaceae ).

Distribution. China: Heilongjiang, Liaoning, Inner Mongolia, Beijing, Hebei, Shanxi, Shaanxi.
