Longhorned beetles (Coleoptera: Cerambycidae) of southeastern Mongolia with particular emphasis on the genus Anoplistes Audinet-Serville, 1833 (Cerambycinae: Trachyderini)

Abstract

New data on the distribution, bionomy, and taxonomy of the longhorned beetles that occur in the poorly studied region of southeastern Mongolia (Ömnögovi, Dornogovi, and Sükhbaatar aimags) are presented together with a list of all taxa that are known from this area. The literature records for all known species from this area were summarized, verified, and mapped. Chlorophorus caragana Xie & Wang, 2012 is recorded from Mongolia for the first time. New localities of some little-known taxa that are endemic to Mongolia and adjacent territories, such as Anoplistes halodendri minutus Hammarström, 1892, Anoplistes kaszabi Karpiński, 2020, and Eodorcadion gorbunovi Danilevsky, 2004 are given. High-quality stacked images of several unique species, e.g., Anoplistes gobiensis (Namkhaidorzh, 1973), Ch. caragana, and Chlorophorus obliteratus (Ganglbauer, 1889) are presented for the first time along with photographs of their habitats. New remarks on highly complex taxonomic issues concerning some species in the genera Anoplistes, Chlorophorus, and Eodorcadion are also provided.

DNA vs. Morphology in Delineating Species Boundaries of Endemic Mongolian Eodorcadion Taxa (Coleoptera: Cerambycidae)

“…The fauna of southern Mongolia is unique, due to the inland location of the country, its geological history, and generally pristine habitats. Many of the cerambycid species found there are endemic to this region (including northern China), and their bionomy is poorly studied [6]. Mongolian ecosystems are under enormous pressure due to climate change (occurring at a much greater rate there than the global average), overgrazing (connected with increase in livestock since its privatisation in 1992), and mining [7,8].…”
