Abstract
An investigation on the habitation of Callipogonrelictus Semenov, 1899 in Gwangneung forest was carried out, where the Korea National Arboretum is located. In an investigation spanning the last eleven years (2007–2017), 22 emergence holes, nine pupal chambers, six adults, and two larvae of C.relictus were identified. In this study, biological information about habitation of C.relictus is provided by comparing and combining the results of this investigation with a survey conducted in Ussurisky Nature Reserve, Russia, in 2015. The distribution is also reviewed to include the Korean Peninsula and a new location of South Korea is added to the distribution for C.relictus.
Highlights
The genus Callipogon Audinet-Serville, 1832, includes nine species in five subgenera worldwide, one of which, C. (Eoxenus) relictus Semenov, 1898, is found in East Asia, while the other eight species are mainly distributed in Central and South America, including Mexico, Guatemala, and Colombia (Lameere 1904; Monne 2017)
In the survey in Gwangneung forest, we found a total of 22 emergence holes on four species of dead tree (Carpinus cordata Blume, C. laxiflora (Siebold & Zucc.) Blume, Quercus aliena Blume, and Q. mongolica Fisch)
During the study period (2007–2017), we found a total of nine pupal chambers of C. relictus in three species of dead trees in Gwangneung forest (Carpinus cordata, C. laxiflora, and Q. aliena)
Summary
The genus Callipogon Audinet-Serville, 1832, includes nine species in five subgenera worldwide, one of which, C. (Eoxenus) relictus Semenov, 1898, is found in East Asia, while the other eight species are mainly distributed in Central and South America, including Mexico, Guatemala, and Colombia (Lameere 1904; Monne 2017). (Eoxenus) relictus Semenov, 1898, is found in East Asia, while the other eight species are mainly distributed in Central and South America, including Mexico, Guatemala, and Colombia (Lameere 1904; Monne 2017). Callipogon relictus, which is known to be one of the largest Coleoptera species in the Palearctic region, was first recorded in Vladivostok, far eastern Russia, and is found in some parts of China, Mongolia and central and northern parts of the Korean Peninsula (Byun et al 2007; Li et al 2013; Yi et al 2018). Thereafter, when a large number of specimens were collected from Chujeon-ri, Buksanmyeon, Chuncheon-si, Gangwon province, this region was designated as a natural monument No 75 on 3 December 1962, a habitat of C. relictus. The habitat was destroyed during construction of the Soyanggang dam, and its natural monument status was annulled on 19 July, 1973
