( Naito, 2020a ). Pteridaceae : Coniogramme intermedia Hieron. ( Naito, 2002 , 2004 , 2020a ), C. japonica (Thunb.) Diels ( Okutani, 1967b ; Naito, 1980 , 1996 ; pres- ent study). Remarks . As the host, Okutani (1967b) and Naito (1980 , 1996 ) recorded Coniogramme japonica , but Naito (2002 , 2020a ) and Naito et al. (2004) mentioned C. intermedia instead of C. japonica without any comment. We confirmed C. japonica as the host by rearing the larva.
