Phymatocera nipponica Togashi, 1958

Japanese name: Higenaga-kuro-habachi

Material examined. HOKKAIDO: 1 ˁ, Bibai, Koshunai , 43°17′N 141°51′E, 24. V. 2015, H. Hara .

Distribution. Japan: Hokkaido ( Matsumura, 1912, as l Phymatocerus aterrimus Klugz, according to Togashi, 1958; Togashi, 1997; pres- ent study), Honshu ( Yano, 1932, as Phymatocera aterrima , according to Togashi, 1958), Shikoku ( Togashi, 1974), Kyushu ( Togashi, 1972). Korea ( Doi, 1938, as l Phymatocera aterrima KLUG [Higenaga-kuro-habachi (in Japanese)]z); Sakhalin ( Haris, 2006); Kuril Islands ( Sundukov, 2017).

Remarks. Although Naito (2019, 2020a) did not include Hokkaido in the distribution and Naito (2020a) questioned its occurrence in Hokkaido, Hara collected the above male in central Hokkaido. It agrees with the original description of Togashi (1958) and goes to this species in the key to the Japanese species of Phymatocera by Togashi (2004).
