( Fig. 1C View Fig )

Host plants. Betulaceae : Alnus japonica (Thunb.) Steud. (new record), Betula ( Shinohara and Hara, 2020) . Cornaceae : Swida ( Kuramitsu et al., 2019) . Eupteleaceae : Euptelea ( Kuramitsu et al., 2019) . Fagaceae : Quercus ( Okutani, 1967a) , Lithocarpus ( Shinohara and Hara, 2020) . Juglandaceae : Juglans mandshurica Maxim. var. sachalinensis (Komatsu) Kitam. (new record). Magnoliaceae : Magnolia ( Kuramitsu et al., 2019) . Oleaceae : Fraxinus ( Kuramitsu et al., 2019) . Rosaceae : Cerasus ( Okutani, 1967a) . Salicaceae : Populus ( Okutani, 1967a) . Sapinda- ceae: Acer ( Okutani, 1967a) .

Remarks. On May 23, 2021, Shinohara found several dead females of this species on the trunks at the height of 1.5–2.5 m of dead trees of the above two newly recorded species standing on the broad riverbed of the Tone River in Koya (about 7 m), Moriya City, Ibaraki Prefecture. Apparently, those females (one of them in Fig. 1C View Fig ) died after oviposition as often observed for siricid females.

This is the first record of Alnus japonica ( Betulaceae ) and Juglans mandshurica var. sachalinensis ( Juglandaceae ) as hosts of Tremex apicalis . This woodwasp is now known to attack various broadleaved trees of eleven families.
