MATERIAL. Holotype ♂ ( USNM) (photograph; Fig. 1), “Shin Kai Si, 4400 ft., Mt. Omei , Szechuen, China, Aug. [19]22, D.C. Graham ”, “ Holotype Trachlophus [= Trachylophus ] rugicollis J.L. Gressitt ”, Type No 58347 USNM”, “ Trachylophus rugicollis Gressitt ” ( Fig. 2).

REMARKS. Until now, a photograph of the general view of the holotype of this little-known species has only been

33

published [ Lingafelter et al., 2013; Lingafelter et al., 2014].

Through the courtesy of Dr Alexander S. Konstantinov (Smithsonian Institution, Washington D.C., USA), I have recently examined the holotype from high-quality photographs of some details of structure and transferred this species from the genus Trachylophus Gahan, 1888 to Neocerambyx [ Miroshnikov, 2020a]. Some of the photographs of the holotype are given here for the first time.

The body length is 32.5– 33 mm [ Gressitt, 1948; Jacquot, 2020].

DISTRIBUTION. China: Sichuan.

According to Jacquot [2020], N. rugicollis has been also recorded in Yunnan (Yingjiang County, Tongbiguan). The records for some other provinces [ Chen et al., 2019] requires reliable confirmation. Niisato and Oh [Catalogue..., 2020: 23–24] have already excluded Taiwan and also Korea which were mentioned for this species in the same publication [ Chen et al., 2019].
