%X A detailed examination of specimens of Cryptopleurum sichuanicum Ryndevich, 2005 from high altitudes of Sichuan Province, China, revealed that the species belongs in the genus Nipponocercyon Sat , 1963 previously endemic to Japan. The species is here transferred in Nipponocercyon, and N. sichuanicus (Ryndevich, 2005), comb. n. is redescribed and compared with N. shibatai Sat , 1963. The male genitalia of N. sichuanicus is described for the first time. An adapted diagnosis of Nipponocercyon is provided, and reasons for the inclusion of N. sichuanicus into Nipponocercyon and the general distribution of the genus are discussed.
