Morophagoides moriutii Robinson, 1986 is an important pest of the shiitake mushroom, Lentinula edodes. After dissecting the abdomen of the holotype of M. moriutii, we recognized that the male genitalia are apparently different from those of the paratype illustrated in the original description at the species level. To provide basic information to assist in the control of pests of the mushroom, we describe the general habitus and genitalia of the true M. moriutii for the first time. Our study also reveals that M. moriutii has a restricted distribution in Honshu and Shikoku, Japan, contrary to the previous belief that the species occurred more widely from Japan (Honshu, Shikoku, Kyushu) to Taiwan. Although M. ussuriensis (Caradja in Deutsch Entomol Zeit 34:75-180, 1920) was formerly assigned to the Japanese representative of the genus Morophagoides, this was proved to be a misidentification by Robinson (Bull Br Mus Nat Hist (Ent) 52(2):37-181 1986) and he described it as a new species, M. moriutii. We have identified the true M. ussuriensis from Japan (Hokkaido, Aomori Pref. and Tsushima Is.) for the first time. Therefore, here we also describe the general habitus and genitalia of true M. ussuriensis.
