Abstract

Data on 38 species and four subspecies of three genera of the tribe Osmiini (Megachilidae) collected in Nakhchivan Autonomous Republic of Azerbaijan are presented. Of them, 19 species and one subspecies are recorded for the fauna of Azerbaijan for the first time. This paper is based on the material of more than 155 specimens, collected by the authors in June 2019 in 21 localities of the republic. Additional 44 specimens of Osmiini from the Nakhchivan Autonomous Republic stored in the collection of the Institute of Zoology of the National Academy of Sciences of Azerbaijan, Baku have also been studied. Currently, 64 species and four subspecies of osmiine bees are known from this country. This is distinctly less in comparison with the adjacent fauna of Turkey (247), Turkmenistan (110) and Iran (88), but more than understudied faunas of Georgia (31) and Armenia (44). It is assumed that the number of Osmiini species in Azerbaijan may be at least twice as large.

Introduction

The osmiine bees (Megachilidae: Osmiini), which comprise 15 genera and roughly 1200 species worldwide, occur in North America, Africa and Eurasia (Müller 2019). They are especially diverse in mediterranean and xeric climates of southern Africa, southwestern North America and the Palaearctic region. With 10 genera and about 700 species, the Palaearctic osmiine bee fauna is particularly diverse.

The present paper is part of a series of publications dealing with the Osmiini of the territory of the Nakhchivan Autonomous Republic of Azerbaijan (Maharramov 2010; Maharramov et al. 2014; Proshchalykin et al. 2019). Until recently, osmiine bees are one of the least-studied groups occurring in this territory as well as in Azerbaijan. So far, only about 29 species of Osmiini have been recorded from Azerbaijan mainly in taxonomic papers (Müller 2019). But in last two years significant progress has been made towards a better knowledge of the species of osmiine bees from this territory. After the publication of Proshchalykin et al. (2019), the number of known Osmiini species increased to 47.

Based on a comprehensive study of specimens, we here list 38 species and four subspecies of three genera of the tribe Osmiini, with 19 species and one subspecies recorded from Azerbaijan for the first time. Currently, 64 species and four subspecies of osmiine bees are known from this country (Table 1). This paper is a further step towards a better documentation of the species of Osmiini and their distribution in the Palaearctic region and adjacent areas.

This paper is dedicated to memory of our wonderful colleague, Dr. Khalid Aliyev, who recently passed away.

Material and methods

This paper is based on the material (155 specimens) collected in June 2019 in the Nakhchivan Autonomous Republic (Azerbaijan) and currently housed in the Federal Scientific Center of the East Asia Terrestrial Biodiversity, Far Eastern Branch of Russian Academy of Sciences, Vladivostok, Russia (FCBV). Specimens were collected by standard methods using net and numerous yellow pan traps in 21 localities. Additional 44 specimens of Osmiini from the Nakhchivan Autonomous Republic stored in the collection of the Institute of Zoology of the National Academy of Sciences of Azerbaijan, Baku (IZAB) have also been studied.

Taxonomy of Osmiini generally follows Müller (2019). For detailed synonymy and distribution of Osmiini species also see Müller (2019). We have used the following abbreviations for collectors: KA – Kh. Aliyev, MM – M. Maharramov, MP – M. Proshchalykin. New species for Azerbaijan fauna are noted with an asterisk (*). views.
