Abstract
Available information about bees of the genus Lasioglossum in Azerbaijan is summarised. One hundred and one species are currently known from this country. Twenty-three species are newly recorded from the Caucasus region and additional eighteen species are newly recorded from Azerbaijan. Three species are excluded from the list of Azerbaijani fauna. A new synonymy is proposed for Lasioglossum euxinicum Ebmer, 1972 = L. alievi Pesenko, 1986, syn. nov., and a lectotype is designated for Halictus schelkovnikovi Kokujev, 1913.
Keywords
Anthophila, Apiformes, fauna, new records, new synonym, the Caucasus region
Introduction
The global genus Lasioglossum Curtis, 1833 currently includes 1,841 described species (
The Caucasus region is a mountainous area between the Black Sea and the Caspian Sea, considered part of the natural border between Europe and Asia. Geographically, it is usually considered part of western Asia, bordering north-eastern Turkey and north-western Iran. The northern edge of the Caucasus is known as the Ciscaucasus and the southern part as the Transcaucasus. The Ciscaucasus contains most of the Greater Caucasus mountain range, also known as the Great Caucasus. It includes the southern part of European Russia (Krasnodar Territory, Stavropol Territory, Adygea Republic, Karachayevo-Cherkessk Republic, Ingushetia Republic, Kabardino-Balkarsk Republic, Severnaya Osetia Republic, Chechenskaya Republic, and Dagestan Republic) and northern parts of Georgia and Azerbaijan. The Transcaucasus is bordered by Russia to the north, the Black Sea and Turkey to the west, the Caspian Sea to the east and Iran to the south. It includes the Caucasus Mountains and the surrounding lowlands. All of Armenia, Azerbaijan (except the northern parts) and Georgia (except the northern parts) are part of the South Caucasus (
The present paper is a part of the ongoing research of bees of the territory of Azerbaijan (
Halictus alpestris [=Lasioglossum costulatum] and H. truncaticollis [=L. truncaticolle] was the first species of the genus described from Azerbaijan (

In this paper we enumerate 101 species of the genus Lasioglossum, including 23 species newly recorded from the Caucasus region, and additional 18 species are newly recorded from Azerbaijan. Three species are excluded from the Azerbaijani fauna.
Materials and methods
The results presented in this paper are based on 2150 specimens collected in Azerbaijan and currently housed in the Zoological Institute, Russian Academy of Sciences (St. Petersburg, Russia,
The subgeneric classification of Lasioglossum is based on the conclusions of
Specimens were studied with an Olympus SZ51 stereomicroscope, and photographs were taken with a combination of stereomicroscope (Olympus SZX10) and digital camera (Olympus OM-D). Final images are stacked composites generated using Helicon Focus v. 7.7.4 Pro. All images were post-processed for contrast and brightness using Adobe Photoshop. New distributional records are noted with an asterisk (*).

Discussion
In total, 101 Lasioglossum species are recorded from Azerbaijan. For comparison, 120 species are known from the whole of the Caucasus (Suppl. material
Only 14 species recorded in Azerbaijan are widespread in the whole Palaearctic region: L. albipes, L. calceatum, L. fulvicorne, L. fratellum, L. leucozonium, L. leucopus, L. lucidulum, L. marginatum, L. politum, L. quadrinotatulum, L. rufitarse, L. tungusicum, L. villosulum, L. zonulum. Twenty-five species are widespread in West Palaearctic: L. ageratum, L. brevicorne, L. clypeare, L. convexiusculum, L. costulatum, L. elegans, L. euboeense, L. fallax, L. interruptum, L. laeve, L. laticeps, L. lineare, L. malachurum, L. morio, L. nigripes, L. nitidiusculum, L. obscuratum, L. quadrinotatum, L. parvulum, L. pauxillum, L. punctatissimum, L. puncticolle, L. semilucens, L. sexnotatum, and L. xanthopus. Six species are distributed in Europe to Caucasus: L. intermedium, L. laevigatum, L. lativentre, L. quadrisignatum, L. setulosum, and L. tarsatum. Fourteen species occur from Mediterranean region or South Europe to Central Asia (or some species to Mongolia and North China): L. aegyptiellum, L. caspicum, L. clypeiferellum, L. discus, L. fallax, L. hilare, L. limbellum, L. longirostre, L. mandibulare, L. mesosclerum, L. pygmaeum, L. picipes, L. subaenescens, and L. truncaticolle.
More than half of the Lasioglossum fauna of Azerbaijan is formed by species with smaller areal or endemic distributions. Twenty-four species are distributed from southern Europe to the Caucasus, or from the Mediterranean to the Middle East and the Caucasus (some species also occur in Iran, Afghanistan and India): L. anellum, L. bicallosum, L. bluethgeni, L. corvinum, L. crassepunctatum, L. cristula, L. epipygiale, L. euxinicum, L. glabriusculum, L. griseolum, L. hethiticum, L. imbecillum, L. kussariense, L. laevidorsum, L. medinai, L. mediterraneum, L. muganicum, L. ordubadense, L. peregrinum, L. podolicum, L. prunellum, L. stolidum, L. subfasciatum, and L. transitorium.
Eleven species have the Caucasus-Central Asian distribution: L. adabaschum, L. ciscapum, L. croceipes, L. equestre, L. euxanthopus, L. hyalinipenne, L. leucopymatum, L. maculipes, L. popovi, L. pastorium, L. skorikovi.
Eight species are endemic to Turkey and the Caucasus (some species found in Iran or northern India): L. araxanum, L. acephaloides, L. argaeum, L. edessae, L. korbi, L. reinigi, L. sociorum, and L. talyschense.
Thus, the fauna of Azerbaijan is very diverse and consists of species with wide Palaearctic or Western Palaearctic ranges, as well as elements of Mediterranean, European, Central Asian faunas and a small number of endemics.
Most species are confined to the steppe zone, polyzonal species are common, but forest and desert species are also found. According to the studied material, Lasioglossum malachurum, L. marginatum, L. politum, and L. glabriusculum are the most common species of Lasioglossum in Azerbaijan.
