Xiphydria kanba Shinohara, Hara and Smith, 2020

New Japanese name: Kanba-kubinaga-kibachi

Specimens examined. Honshu: Tochigi Pref.: 1 Ə, Nikko, Yumoto , 20. VIII. 2012, S. Maehara; 2 Ə, Nikko, Chûgûshi, nr. Chûzenji-ko, from dead fallen branch (3–5 cm thick) of Betula platyphylla var. japonica , coll. 19. V. 2022, em. 13 and 17. VI. 2022 (indoors in Tsukuba), A. Shinohara; 1 Ə, Yaita, Happôgahara, 4. VIII. 2015, S. Maehara. See Shinohara et al. (2020) and Shinohara and Hara (2020) for more collection records .

Remarks. In Honshu, this species has been recorded from a few specimens collected only in two localities, Marunuma, Gunma Prefecture and Chûgûshi, Tochigi Prefecture, only 16 km apart, both about 1300–1400 m alt. (Shinohara et al., 2020; Shinohara and Hara, 2020). Of the four newly acquired specimens (see above), three are from the already known habitat (Chûgûshi and nearby Yumoto, Nikko) and one is from Happôgahara (1000–1150 m alt.), Yaita, which is 40 km away from the previously known localities. The currently known distribution range of this species in Honshu is thus quite narrow. The real distribution range of this species should be confirmed by further collecting.

In 2022, two males emerged on 13 and 17 June from a dead and fallen branch of Betula platyphylla var. japonica obtained in Chûgûshi on 19 May. At the same locality and from the same plant species, one female emerged on 10 August, 2019 (branches collected on 7 August, 2019) and two females emerged on 2 and 20 July, 2020 (branches collected on 10 June, 2020). All the dead branches were collected in the same site, meaning that the adults occur in this area for fairly a long period from the middle of June to the middle of August .
