A new species of the genus Eremochorus Zaslavskij, 1962 (Coleoptera: Curculionidae) from Central Altai (Russia) with systematics remarks

Abstract

A new species, Eremochorus (Eremochorus) kalashiani Legalov, sp. nov. from Ongudaisky District, Central Russian Altai of Western Siberia is described and illustrated. The new species is similar to E. steppenis (Motschulsky, 1860) from Kazakhstan but differs from it in the wider aedeagus with quite short apex, and not rounded sides of the pronotum. Eremochorus (Eremochorus) mniszechi (Capiomont, 1868), comb. n. and E. (E. belokobyskyi (Legalov, 2011), comb. n. are transferred from genus Asiodonus to genus Eremochorus and two new combinations of names were established. A list of species of the genus Eremochorus is compiled. A distribution map for E. kalashiani Legalov, sp. nov. and E. mniszechi is given.

A new species of the genus Macrotarrhus Bedel, 1906 (Coleoptera: Curculionidae) from South-Western Mongolia with a list of the species

“…This is the third species of the genus found in Khovd Province. This study is a continuation of research on the tribe Hyperini by A.A. Legalov (Legalov 1997(Legalov , 1999a(Legalov , 1999b(Legalov , 2008(Legalov , 2011a(Legalov , 2011b(Legalov , 2011c(Legalov , 2012a(Legalov , 2012b(Legalov , 2012c(Legalov , 2018(Legalov , 2020b(Legalov , 2021(Legalov , 2022a(Legalov , 2022b(Legalov , 2023Legalov & Reshetnikov 2020, 2022.…”

Two new species of the tribe Hyperini (Coleoptera, Curculionidae) from Central Asia

“…This species was recorded for this country by Petri (1901) who described Macrotarsus setosus Petri, 1901 (synonym for E. concinnus) from "Buchara". No other records of the Eremochorus species from Uzbekistan are known (Bajtenov 1974;Legalov 2023a). The new species is the second find of this genus for Uzbekistan.…”

“…The terminology of weevil body is according to Lawrence et al (2010). The systematics of studied taxa are based on Alonso-Zarazaga et al (2023) and Legalov (2011Legalov ( , 2020Legalov ( , 2023aLegalov ( , 2023b Description. Body black, covered with sparse weakly dissected apically scales and semierect setae.…”

“…Almost all species of genera Eremochorus Zaslavskij, 1962 andMacrotarrhus Bedel, 1906 inhabiting the arid regions of Asia are endemics. Despite the significant number of known species from these genera, 48 described species for Eremochorus and 36 described species for Macrotarrhus (Alonso-Zarazaga et al 2023;Legalov 2023aLegalov , 2023b, new species are constantly being discovered.…”

“…Fauna of the genus Eremochorus in Uzbekistan was presented by E. concinnus (Boheman, 1842) (Legalov 2023a). This species was recorded for this country by Petri (1901) who described Macrotarsus setosus Petri, 1901 (synonym for E. concinnus) from "Buchara".…”
