A checklist of family Bembicidae from Tunisia is compiled based on data available in the literature, new material collected from different localities in Tunisia between 2017 and 2019, and some specimens hosted in the Muséum National d’Histoire Naturelle, Paris, France. As a result, 49 species and two subspecies in 16 genera of the family Bembicidae are recorded. Two genera: Psammaecius Lepeletier de Saint Fargeau, 1832, and Brachystegus A. Costa, 1859, are reported in this study for the first time. This is in addition to nine species and subspecies: Alysson ratzeburgi Dahlbom, 1843, Psammaecius eremorum de Beaumont, 1952, Stizoides klugii (F. Smith, 1856), Stizus fuscatus Morice, 1897, Stizus niloticus saharae Roth, 1934, Stizus pubescens arenarum Handlirsch, 1892, Stizus ruficornis strigatus Mochi, 1939, Stizus vespoides (Walker, 1871) and Brachystegus braueri (Handlirsch, 1887) that are new for the Tunisian fauna. New localities are also reported for several species and subspecies that had already been reported from Tunisia. Identified taxa are illustrated by digital photographs and their global and Tunisian distribution is presented.

Graellsia, 78(1): e159. https://doi.org/10.3989/graellsia.2022.v78.321 Introduction

Bembicidae is a family of Spheciformes wasps; it is considered as a separate family within the superfamily Apoidea according to Sann et al. (2018, 2021). It includes 1694 species and subspecies belonging to 81 genera (Puławski, 2021); almost 25% of these species inhabit the Palearctic region (Nemkov, 2017). Generally, members of this family are small to large wasps nesting in sandy areas and hence they are collectively referred to as “sand wasps”. The majority of them have hunting behavior except for Nysson Latreille, 1802 species, which are cleptoparasites (Bohart & Menke, 1976). Faunistic and systematic studies dealing with genera in this family date back to the studies of Handlirsch, who described 15 genera between 1887 and 1895, including nine genera from the Palaearctic region (Bitsch et al., 1997). In this region, many studies have dealt with different genera, including de Beaumont (1953, 1954), who revised Gorytes Latreille, 1805 and Bembecinus A. Costa, 1859. More recently, Schmid-Egger (2004, 2005, 2019) studied genera Bembecinus, Olgia Radoszkowski 1877andAmmatomus A. Costa, 1859. These and other previous studies (Costa, 1893a, 1893b; Schulz, 1905; Smits van Bürgst, 1913a, 1913b; von Schulthess, 1926) provided some records from Tunisia, but a detailed study about the Tunisian fauna of this family is not available. The present paper is a contribution to the knowledge of the Bembicidae fauna in Tunisia; it is a continuation of previous studies (Ben Khedher et al., 2019, 2020a, 2020b, 2020c, 2020d, 2020e, 2021a, 2021b) dealing with Spheciformes wasps in Tunisia.

 Material and methods

To compile a checklist of Bembicidae species in Tunisia, we used available data in the literature and newly collected material. Newly captured specimens were collected from different regions in Tunisia by sweep netting during the spring and summer seasons from 2017 to 2019. Specimens of Tunisian origin hosted in the Muséum National d’Histoire Naturelle, Paris, France (MNHN) were also examined.

Identification of specimens was done by the first author following mainly Guichard (1989a, 1989b), Schmid-Egger (2004, 2005, 2019), and de Beaumont (1952). Identification was then confirmed by comparing with syntypes (Bembix galactina Dufour, 1854 and Stizus niloticus saharae Roth, 1934) and with other identified material hosted in MNHN. Some specimens were re-identified and confirmed by Dr. Toshko Ljubomirov (Bulgaria) (Ammatomus, Bembecinus, Bembix, Hoplisoides, and Olgia species) and by Dr. Christian Schmid-Egger (Germany) (Psammaecius). Published records from Tunisia and general distributions of all the species listed in this study were compiled in order to present updated distribution maps. The global distribution maps follow mainly Puławski (2021).

Digital photographs were taken by an integrated system composed of a Canon EOS 1100 DSLR digital camera and Helicon remote (Version 3.9.10 W) (MNHN-Paris). The digital images were labelled using Adobe Photoshop CS 6.

Identified materials are deposited in the private collection of the first author at the Laboratory of Entomology and Insect Ecology, Regional Research Centre for Horticulture and Organic Agriculture (CRRHAB) at Chott Meriem, Sousse, Tunisia, and in Atatürk University Biodiversity Science Museum (ABBM), Erzurum, Turkey.

 Discussion

In this study, 49 species and two subspecies of the family Bembicidae are listed in Tunisia (Table 1). The genus Bembix is the most diversified with 12 species and two subspecies. Of these, eight genera (Argogorytes, Brachystegus, Gorytes, Harpactus, Nysson, Olgia, Oryttus and Psammaecius) have only one species. Two genera: Psammaecius and Brachystegus are newly recorded from Tunisia. All collected localities of P. eremorum are Saharan. Consequently, this new record confirms the qualification of P. eremorum as a Saharan species by de Beaumont (1952). Brachystegus is represented in Tunisia by one species, B. braueri. This species is distributed only in North Africa (Algeria, Morocco and Tunisia) and in Palestine.

Additionally, Alysson ratzeburgi, Stizoides klugii, Stizus fuscatus, Stizus niloticus saharae, Stizus pubescens arenarum, Stizus ruficornis strigatus and Stizus vespoides are new for the Tunisian fauna. The species A. ratzeburgi was known only from Algeria (Morice, 1911), and the new data extends its distribution to Tunisia. Stizus niloticus saharae and S. pubescens arenarum have a North African distribution, whereas the remaining species extend to Africa, Israel and the Arabian Peninsula.

Total 16 genera 49 species and 2 subspecies

The presence of Stizus tunetanus, Bembix palaestinensis and Hoplisoides punctuosus curtulus in Tunisia was also confirmed in this study. Moreover, we provide new records for other previously recorded Bembicidae species from Tunisia. This study improves our knowledge of the Tunisian Bembicidae fauna with the first checklist of the family in the country, but further investigations are needed to provide new records for the country and new species for science.
