Strongylogaster moiwana Matsumura, 1912

Japanese name: Iwagane-zenmai-habachi

( Fig. 8C )

Material examined. HONSHU: Tochigi Pref.: 1 ˁ, Nakagawa , Oyamada, coll. larva, on Coniogramme japonica , 30. V. 2017, mat. 7. VI., em. 30. III. 2018, S. Ibuki .

Larva. Late instar larva ( Fig. 8C ): head pale brown, black on vertex and lateral part; trunk and legs pale yellowish green.

Host plants. Onocleaceae : Onoclea sensibilis L. var. interrupta Maxim. ( 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.
