Anambulyx szechuanus Clark, 1938, Proc. New Engl. zool. Club 17: 43. Type locality: Southwestern China, Szechuan [Sichuan], Mt Omei [Emei Shan], 9000'.

Synonym. Smerithus [sic] litulinea Zhu & Wang, 1997, Fauna Sinica, Insecta 11: 272. Type locality: China, Sichuan, ??Yahongmu.

Note. The original Chinese description of S. litulinea incorrectly stated that the type locality was Yunnan, while the English description and the holotype label (in Chinese) give Sichuan. However, we were unable to find the locality 'Yahongmu' on any map or in any gazetteer.
