Abstract The paper provides information on the distribution of 45 species of Heteroptera from 10 families in the Kurai steppe in the southeast of the Russian Altai (Altai Republic). Of these, Mimula scutellaris Kiritshenko, 1931 recorded for the first time for the fauna of Russia and Bagrada stolida (Herrich-Schaeffer, 1839) — for Siberia. Following 15 species are recorded as new for the Altai Republic: Nabis punctatus mimoferus Hsiao, 1964 (Nabidae); Deraeocoris ventralis ventralis Reuter, 1904, Apolygus nigronasutus (Stål, 1858), Lygidea illota (Stål, 1858), Lygus rugulipennis Poppus, 1911, Lygus wagneri Remane, 1955, Globiceps fulvicollis Jakovlev, 1877, Psallus betuleti (Fallén, 1807) (Miridae); Neides propinquus Horváth, 1901 (Berytidae); Ortholomus punctipennis (Herrich-Schaeffer, 1838), Kleidocerys resedae resedae (Panzer, 1797), Cymus glandicolor Hahn, 1832, Xanthochilus quadratus (Fabricius, 1798) (Lygaeidae); Myrmus calcaratus Reuter, 1891 (Rhopalidae); Sciocoris abbreviatus (Reuter, 1879) (Pentatomidae). Key words: Biodiversity, Heteroptera, Kurai Steppe, south-western Altai, Siberia, fauna, new records. Introduction In the paper presents new data on true bugs of the Kurai steppe which occupies vast intermontane depression up to 20 km across and 1500–1600 m above sea level in the middle reaches of the river Chuya in the South- East of Altai Mountains (Altai Republic). From the north, the depression is framed by the high (3000 m and higher) Kuraisky, and from the south by the North-Chuyskiy mountain ridges (Figs 1, 2). The vegetation of the mountain steppe is depleted and shows similarities with the deserted steppes of Mongolia. South-Eastern Altai as well as South Tuva located to the east are outposts of the Central Asian semi-deserts in Southern Siberia, and in zoogeographic terms these territories are of great scientific interest. Especial studies on heteropterans in the South-East Altai have not been carried out, there are only scattered information in publications of various authors (Kiritshenko 1910a, 1910b; Kovrigin 1958, 1965; Péricart 1969; Petrova 1975; Kerzhner & Josifov 1966; Kerzhner 1970, 1972, 1979, 1981; Golub 1977; Ecologica Montenegrina, 38, 2020, 25-35 HETEROPTERANS OF KURAI STEPPE, RUSSIAN ALTAI Vinokurov & Golub 2007, 2009; Vinokurov & Kanyukova 1995; Kanyukova & Vinokurov 2009; Vinokurov 2019, Vinokurov & Rudoi 2020, etc.). A.N. Kiritshenko (1910a, 1910b) according to the collections of E.G. Rodd for the Chuya steppe first indicated nine species of bugs belonging to eight families: Saldidae — Salda littoralis (Linnaeus, 1758); Miridae — Deraeocoris punctulatus (Fallén, 1807), Lygus pratensis (Linnaeus, 1758); Lygaeidae — Lamprodema maura (Fabricius, 1803); Alydidae — Megalotomus ornaticeps (Stål, 1858); Cydnidae — Camptophorus niveimarginatus Scott, 1874; Scutelleridae — Odontoscelis fuliginosa (Linnaeus, 1761), Phimodera reuteri Kiritshenko, 1910; Pentatomidae — Aelia sibirica Reuter, 1884. Significant hemipterological material from this part of Altai was collected by an expedition of the Zoological Institute of the Russian Academy of Sciences (St. Petersburg) with the participation of I.M. Kerzhner, a prominent specialist in the order Heteroptera in 1964. During the study of these collections, still undescribed endemics of the Altai-Sayan mountainous country were found, such as: Xylocoris altaicus Péricart, 1969 (Anthocoridae), Myrmedobia asiatica Péricart, 1969 (Microphysidae), Teratocoris coriaceus Vinokurov, 1995, Dimorphopterus atrans Kerzhner, 1970, Systellonotus lesbia Linnavuori, 1972, Agraptocoris oncotyloides Vinokurov, 1995 (Miridae), Dictyonota nigricosta Kerzhner, Josifov, 1966, Tingis altaica Golub, 1977 (Tingidae). Below are listed data on 45 species of Heteroptera belonging to 10 families collected in the Kurai steppe. Figure 1. Kurai steppe in South-East Altai (photo by A.E. Naydenov). Material and methods Investigations were carried out in the Kurai steppe in late July–early August 2019 on the territory of the Kosh-Agach and Ulagan Districts of the Altai Republic (Fig. 2). The bugs were collected in steppe, meadow, and forest biotopes using methods accepted in entomology (Fasulati 1971; Golub et al. 2012). A small but interesting material in total 110 specimens were collected including some species that not previously recorded from Altai Mts. Of them Mimula scutellaris Kir., and Bagrada stolida H.-S. were transferred to the Heteroptera collection of the Zoological Institute of the Russian Academy of Sciences (St. Petersburg). 26 VINOKUROV & RUDOI Figure 2.
