Totally, 27 species under 3 genera belonging to Halictinae (Hymenoptera, Halictidae) are listed, of which Sphecodes cristatus Hagens, 1882, and Lasioglossum zunaga Sakagami, 1995, are documented as new records for Iraqi entomofauna. They were described and illustrated, as well as the distribution, basionyms, and synonyms of genera and species are provided. Keywords: Distribution, Halictid bees, Iraq, New record, Sphecodes. INTRODUCTION Halictidae is considered the second largest assemblage of bees, comprising around 4890 documented species across the Global Biodiversity Information Facility Secretariat (2023). Sweat bees include some of the commonest species, they are found in many moderate regions of the world and in different ecosystems, they have a significant contribution to the pollination of other insects, for 87 out of the 115 major world food crops to produce vegetables, fruits, and seeds, animal pollination is essential (Klein et al., 2007). According to Kirkitadze and Japoshvili (2015), a significant proportion of agricultural production, approximately 75%, is reliant on the intensity of pollination; the members of this family exhibit a global distribution across tropical and temperate regions, with the exception of Antarctica (Ascher et al., 2017). It is considered the second largest assemblage of bees. Halictid bee community lives on orchard fields; in contrast, this group is maintains wild farms that provide food and nesting areas (Akoijam et al., 2021). The most important morphological features of this family include: laciniae small, hairy lobe on the anterior surface of the labio-maxillary tube above the rest of the maxilla; single subantennal suture below each antennal socket; a distinct stigma; the 1st flagellomere segment is clearly shorter than the scape (Michener, 2007). In addition to, Saini and Vikram (2012) found that the bees belonging to this particular family exhibit a short tongue and a prominently curved basal vein in their fore wing.

The most important morphological features are: episternal sulcus is distinct and directed strongly downward below the scrobal sulcus; when there are three SMC, SMC3 shorter than SMC1 and less than twice as long as SMC2, apex of MC cell pointed or minutely truncate; prepygidial fimbria of female divided by a longitudinal median zone/or triangle of very fine. The members of the frequently common subfamily Halictinae nest in burrows in banks or soil; Halictinae are classified into two tribes, including Augochlorini and Halictini; the most important morphological characters include: longitudinal median specialized area of T5 of females of nonparasitic forms not divided by a notch or cleft; parasitic forms non-metallic or with dull greenish coloration; seventh tergite of male with a transverse ridge, usually carinate, forming a false apex beneath which the tergum is strongly reflexed to the apical margin; surface above the transverse ridge usually with an identifiable hairless pygidium. Regarding to the available literature, it was observed that this particular group has received limited attention from researchers in Iraq, with only a few scattered studies obtainable; for example, Augul (2018) conducted a general survey of the diversity of bees, including Halictidae, while Ahmed (2015) focused on the taxonomic aspects of this guild's species in Northern Iraq. Despite the significance of Halictidae as pollinators for numerous plants, the studies on this group have been comparatively fewer than those on Apidae species, particularly honey bees in Iraq (Glaiim et al., 2008; Glaiim ,2009; Hussin, 2015; Shaher and Nasrallah, 2018; Dagher and Shaher, 2023; Awwad and Shaher, 2023; Sahood et al., 2023). The studies about this family, especially those related to taxonomical aspects in Iraq, are insufficient and scattered, hence, the current study aimed to update the data on these bees, especially the Halictinae subfamily. MATERIALS AND METHODS Specimens collecting: Bees were collected from Salahaddin, and Duhok Provinces, then labeled, and deposited at Iraq Natural History Research Center and Museum- University of Baghdad. Specimens examined: Specimens were examined by Dissecting microscope, Altay), and photographed by digital microscope. They were identified using the different keys: Kirkitadze and Japoshvili (1995); Michener (2007); BWARS (2012); Astafurova and Proshchalykin (2014); also the identification assured by Prof. Dr. Razzaq Shalan Augul, Iraq Natural History Research Center and Museum. The synonyms and basionyms are provided according to EL- Akkad and BibarsI (2015), Augul (2018), Astafurova and Proshchalykin (2020), and GBIF Secretariat (2023).

CONCLUSIONS The diversity of bees is great, and we need more studies to investigate the presence of other new species for science or as a new record in Iraq and on the other hand, the possibility of studying it at the molecular level due to the similarity of species belonging to the same genus to confirm the morphological diagnosis is remarkable. 692 BULLETIN OF THE IRAQ NATURAL HISTORY MUSEUM New records of halictid The current study has provided an updated checklist for Halictinae species supported by basionyms and synonyms to avoid confusion in future studies. Furthermore, the study of the remaining species of the family Halictidae and preparation an updated checklist that includes the basionyms and their synonyms is necessary for the importance of the ecosystem and the sustainability of food sources.
