This study contributes to the knowledge of genus Hylaeus Fabricius, 1793 (Hymenoptera: Colletidae) in Türkiye based on specimens collected from Diyarbakır and Bingöl provinces in eastern Türkiye between 2016–2021. For eastern Türkiye 19 species of Hylaeus were recorded. Among them, Hylaeus (Dentigera) alievi Dathe & Proshchalykin, 2021 and Hylaeus (Hylaeus) hungaricus (Alfken, 1905) are new records for the Turkish fauna. Collection localities, distributions and photographs of all species are provided.

Este estudio contribuye al conocimiento de la fauna del género Hylaeus Fabricius, 1793 (Hymenoptera: Colletidae) en Turquía con base en especímenes recolectados en las provincias de Diyarbakır y Bingöl ubicadas en el este de Turquía entre 2016 y 2021. Para la parte oriental de Turquía, 19 especies del género Hylaeus han sido identificadas. De estas, dos especies, a saber, Hylaeus (Dentigera) alievi Dathe & Proshchalykin, 2021 e Hylaeus (Hylaeus) hungaricus (Alfken, 1905) son nuevos registros para la fauna turca. Se proporcionan localidades de colecta, distribuciones y fotografías de todas las especies.

The world bees are comprised of roundly 20 000 species of seven families: Andrenidae, Apidae, Colletidae, Halictidae, Megachilidae, Melittidae, and Stenotritidae (Michener, 2007; Ascher & Pickering, 2021). Among these families, the Colletidae family contains more than 2700 species worldwide (Zhou et al., 2020). This family is represented in the Palearctic region with only two genera including Colletes Latreille, 1802 (Colletinae) and Hylaeus Fabricius, 1793 (Hylaeinae) (Michener, 2007). The genus Hylaeus contains 55 subgenera and more than 750 species worldwide (Michener, 2007; Dathe, 2015; Ascher & Pickering, 2021). The genus Hylaeus has more than 200 species belonging to 11 subgenera from the Palaearctic region (Michener, 2007; Proshchalykin & Dathe, 2012, 2016, 2017; Dathe, 2015). Türkiye’s Hylaeus fauna consists of 86 species belonging to 10 subgenera (Özbek & Dathe, 2020). Previous studies have been carried out on Hylaeus in Türkiye (Alfken, 1931; Warncke, 1972, 1981, 1992; Özbek, 1977; Çalmaşur & Özbek, 1999; Dathe, 2000; Özbek, 2008a, 2008b, 2011; Özbek & Dathe, 2020); however, the genus is still poorly known in this country.

In this study, a list of 19 species of Turkish Hylaeus with two new records is presented together with notes on their local and general distributions.

Material and methods

This study is based on specimens of the genus Hyleaus Fabricius, 1793 collected from Diyarbakır and Bingöl provinces located in the east of Türkiye between 2016–2021 (Fig. 1). Samples were collected with a sweep net in various localities, killed within ethyl acetate and pinned and labeled with needles suitable for body sizes subsequently. All samples were collected by Emin Kaplan and determined to species by Holger Dathe (Germany). Both classification and nomenclature followed Michener (2007) and Ascher & Pickering (2021). Photographs of morphological characters of adults were taken by using a digital camera attached to a stereomicroscope. The material is stored in Emin Kaplan’s individual collection of the Department of Plant Protection, Faculty of Agriculture, Bingol University (Bingol- Türkiye). Local distributions are given according to biogeographic regions of Anonymous (2023).

 Discussion

In this study, 19 species from seven subgenera of Hylaeus: Abrupta (one species), Dentigera (five species), Hylaeus s. str. (four species), Lambdopsis (one species), Paraprosopis (three species), Prosopis (four species), and Spatulariella (one species) are listed. Among them, two species, Hylaeus (Dentigera) alievi and Hylaeus (Hylaeus) hungaricus are new records for the Turkish fauna. Thus, the number of species of genus Hylaeus reported from Türkiye is increased from 86 to 88 by the present study. Also, seven species for Bingol and ten species for Diyarbakir are new records for provincial fauna. According to the number of specimens, H. cornutus, H. rugicollis, H. imparilis, H. pictus and H. taeniolatus are respectively dominant species in the study area. The species H. cornutus, H. imparilis, H. rugicollis, and H. longimaculus are dominant in all biogeographic regions of Turkey. On the other hand, only single specimens could be collected for H. communis, H. hungaricus, H. leptocephalus, H. trifidus and H. excelsus. While only male individuals were collected from the species H. gredleri, H. communis, H. soror, andH. excelsus, only female individuals were collected from the species H. hungaricus, H. leptocephalus, H. trifidus, and H. taeniolatus. Both male and female individuals were collected from other species. It is thought that the real number of species of Hylaeus in the Türkiye is higher. Therefore, future research in this region will certainly reveal many new species not only for the fauna of Türkiye but also for science. The eastern part of Türkiye proved to be an important centre of diversity for Hylaeus species (Özbek & Dathe, 2020).

Morphological differences among the identified species, and between males and females, are very distinctive in frontal view character combinations. For example, in females of H. cornutus character combinations (face all black and clypeus anterior margin pointed and forked; scape completely black, not dilated; flagellum black above, brown underneath) differ from males of the same species (face all black and clypeus anterior margin not pointed and not forked; scape completely yellow and dilated; flagellum black above, yellow underneath). While the face is completely black in H. rugicollis, there are dark white spots in the paraocular area in H. longimaculus. Clypeus yellow spots are present in females of H. rubicola, H. scutellatus, and H. pictus. The supraclypeal area yellow spot is charactersitic of female H. scutellatus. In females of H. hungaricus the malar area is long. In males of H. alievi, H. scutellatus, H. meridionalis, and H. rugicollis, the face is yellow, with less punctuation and shiny; the scape is yellow and black, fairly well dilated, whereas the scape is completely black and not dilated in males of H. longimaculus.

The contributions made to the number of Turkish Hylaeus species in the current study could mirror the ecological importance and high biodiversity of the Turkish fauna. Although a few studies have been done before, the Turkish Hylaeus fauna corresponds to approximately 44% of the Palaearctic region fauna, suggesting future faunistic studies in the country can reveal additional species in the Hylaeus fauna of Türkiye.
