Natsuki Kaizawa (1st year student of Obihiro University of Agriculture and Veterinary Medicine, Environmental Ecology Course) and Takeo Yamauchi, Associate Professor of Environmental Agriculture Research Division, said that the centipede collected in Obihiro City is a new record species in mainland Japan. It was discovered that it was "Lithobius forficatus (new name in Japanese name) Lithobius forficatus (Lithobius forficatus)".
Associate Professor Yamauchi, who arrived at Obihiro University of Agriculture and Veterinary Medicine in 2019, noticed that a mucade species that had never been seen in Honshu invaded a house rented in Obihiro City, and was a fourth-year student in the Faculty of Agriculture and Animal Science at that time. I did research with Mr. Tsuki.
As a result of a detailed investigation of the morphology of centipede by Mr. Kaizawa, the morphological features such as the tergum, jaw limbs, eyes, male and female gonopods, and the coxal gland foramen of the limbs show that the "Lithobius forficatus" has not been recorded in mainland Japan. It was clarified that it was.
This species also inhabits the urban areas of Obihiro City normally and has the property of invading indoors, and was recognized as the first house pest in Japan as a species of the order Ishimukade.This species is widely distributed in the world, but since it was found only on Etorofu Island in the northern territories in Japan, this discovery sets a new record for this species in mainland Japan.
This finding indicates that research on invertebrates in eastern Hokkaido is very late.
Since "Lithobius forficatus" does not have a Japanese name, a new Japanese name "Ochairoishimukade" is proposed in the paper.This paper was published in the journal "Acta Arachnologica" of the Arachnological Society of Japan on June 2021, 6.
