New data on the longhorn beetles of Mongolia with particular emphasis on the genus Eodorcadion Breuning, 1947 (Coleoptera, Cerambycidae)

Abstract. New data on the distribution, biology, and ecology of the longhorn beetles occurring in Mongolia are presented together with a list of 35 species that were collected during a one-month entomological expedition in August 2015. New localities of some rare taxa endemic to Mongolia, such as Eodorcadion dorcas dorcas (Jakovlev, 1901), E. humerale impluviatum (Faldermann, 1833), and E. intermedium intermedium (Jakovlev, 1889) are given. High-quality photographs of several rather unique species, i.e., Pachytodes longipes (Gebler, 1832), Eodorcadion maurum australe Danilevsky, 2014, E. oryx (Jakovlev, 1895), Monochamus impluviatus impluviatus (Motschulsky, 1859), and M. sutor longulus (Pic, 1898) along with images of their habitats or feeding grounds are also presented. Furthermore, the ecological role of the fireweed Chamaenerion angustifolium (L.) Scop. in the case of boreal anthophilous cerambycid species is highlighted for the first time.
