Abstract

Iraq is a large country in the Middle East region that borders both Turkey and Iran, countries known to host two of the largest bee faunas globally, as expected for a group of insects that favour dry to Mediterranean climates. Despite this huge regional species richness, the bee fauna of Iraq is chronically understudied and poorly known, both in relative and absolute terms. This is true for the hyper-speciose bee genus Andrena, for which only 17 species have been previously published for Iraq. This work is the first modern contribution to the revision of the Andrena fauna of Iraq. Based on new specimen collections in Duhok Governorate (Iraqi Kurdistan) during 2023, a revised total of 59 Andrena species for Iraq (42 species recorded for the first time) is presented, including the description of two new species: Andrena (Aciandrena) duhokensis Wood, sp. nov. and Andrena (Notandrena) baiocchii Wood, sp. nov. The unknown males of A. (Micrandrena) elam Wood, 2022, A. (Micrandrena) obsidiana Wood, 2022, and A. (Notandrena) ayna Wood, 2023 are described. Andrena bakrajoensis Amin & Mawlood, 2019, syn. nov. is synonymised with A. (Holandrena) variabilis Smith, 1853. Additional records are presented from nearby Middle Eastern countries, particularly Lebanon. These results highlight the fundamentally understudied nature of the Iraqi Andrena fauna.

Introduction

Andrena is the second largest genus of bees with approximately 1,700 species following recent revisions (e.g., Pisanty et al. 2022a; Wood and Monfared 2022; Wood 2023, 2024). Andrena are known for their explosive radiation and rapid rate of speciation (Bossert et al. 2022), and are likely to have evolved in the Middle East region ca 25 million years ago (Pisanty et al. 2022b). In line with this expected point of origin, the Andrena faunas of several Middle Eastern countries are very large, with ca 220 species known from Israel, 215 species known from Iran, and 388 species known from Turkey (Pisanty et al. 2022a; Wood and Monfared 2022; Wood 2023, 2024; Wood, unpublished data). The Andrena fauna of Syria is also large, but has not been comprehensively revised, and many species are present which have not yet had their occurrence formally published, with ~ 154–166 species known but not yet fully demonstrated or confirmed (Wood 2020; Wood et al. 2020; Pisanty et al. 2022a; Wood and Monfared 2022; Wood, unpublished data).

In contrast, the published Andrena fauna of the country of Iraq is extremely small, with only 17 species mentioned across various literature sources (Morice 1921a, 1921b; Derwesh 1965; Warncke 1969; Khalaf and Al-Omar 1974; Moalif 1994; Gusenleitner and Schwarz 2002; Scheuchl and Willner 2016; Augul 2018; Amin and Mawlood 2019; Ascher and Pickering 2023), some of which primarily cite previous publications without adding any new information, or which never present detailed specimen records at all. The Iraqi Andrena fauna has very rarely received dedicated attention, most frequently with species listed without supporting specimens or mentioned museum depositories, in strong contrast to neighbouring Turkey (e.g., Warncke 1965, 1974, 1975; Scheuchl and Gusenleitner 2009; Scheuchl and Hazir 2012; Hazir et al. 2014; Wood 2023) and to a lesser extent Iran and Syria (e.g., Popov 1967; Khodarahmi Ghahnavieh and Monfared 2019; Wood et al. 2020; Wood 2020; Radchenko et al. 2021; Wood and Monfared 2022).

Given the very high Andrena species richness found in nearby countries, it is clearly implausible that the Iraqi Andrena fauna is so small. In order to counter this knowledge deficit, we conducted new collections in northern Iraq during spring 2023, and critically reviewed the literature and museum collections in order to produce an updated faunal total.

Materials and methods

Andrena specimens were collected from various localities in Duhok province, Iraq (Kurdistan region) during May 2023 (Fig. 1: locations 1, 2, and 3). Specimens were collected using yellow pan traps which were filled with water and placed adjacent to vegetation (Fig. 2C).

Morphological terminology follows Michener (2007). The following abbreviations are used in the species descriptions: A = antennal segments, S = metasomal sterna, and T = metasomal terga. In diagnoses, the defining characters of a species are given, with those of the indicated comparison species given in parentheses. Subgeneric concepts follow Pisanty et al. (2022b). Specimens were measured from the centre of the clypeus at the front of the head to the apical tip of the metasoma to the nearest 0.5 mm. In the faunal list, taxa are presented alphabetically, first by subgenus and then by species. In the full faunal list, species entries followed by an asterisk (*) indicate the first record for Iraq. Likewise, for the global distributions of species, countries marked with an asterisk (*) indicate the first published record for that country. All specimens were identified by T.J. Wood.

Photographs were taken using an Olympus E-M1 Mark II with a 60 mm macro lens. Additional close-ups were taken with the addition of a Mitutoyo M Plan Apo 5X infinity corrected objective lens. Photographs were stacked using Helicon Focus B (HeliconSoft, Ukraine) and plates were prepared in GNU Image Manipulation Program (GIMP) 2.10. Post-processing of some images was made in Photoshop Elements (Adobe Systems, USA) in order to improve lighting to highlight specific characters. The map of Iraq was taken from GISGeography (2024).

Results

Full Iraqi faunal list

Andrena (Aenandrena) aeneiventris Morawitz, 1872

Literature records

Gusenleitner and Schwarz (2002: dot map 11); Scheuchl and Willner (2016); Ascher and Pickering (2023).

Remarks

We have not examined any specimens of this species, but the presence of this species in Iraq is highly plausible based on its known global distribution, the map records indicated by Gusenleitner and Schwarz (2002), and the presence of this species in neighbouring Turkey and Iran.

Distribution

West and Central Palearctic (Gusenleitner and Schwarz 2002; Osytshnjuk et al. 2005).

Andrena (Notandrena) aerinifrons Dours, 1873 *

Material examined

Iraq: Mosul, edges of a river, 7.iv.1988, 1♂, leg. Olejníček, OÖLM; Lebanon: Balbek-Hermel, Sefri, Haouch Snaid, AUB farm, 33.9244°N, 36.0754°E, 1000 m, 6.iv.2023, 1♂, 8♀, leg. T.J. Wood, TJWC.

Remarks

The status of the subspecies levantina Hedicke, 1938 (which nominally occurs in the Middle East) is unclear, and may not be merited, although A. aerinifrons sensu lato shows high and difficult-to-interpret intraspecific variation in its mitochondrial DNA barcode (Wood, unpublished data).

Distribution

Andrena aerinifrons sensu lato is distributed from Iberia and North Africa to the Middle East including Iraq* and Iran (Gusenleitner and Schwarz 2002; Wood and Monfared 2022).

Andrena (Taeniandrena) afzeliella (Kirby, 1802)

Literature records

Gusenleitner and Schwarz (2002: dot map 345, as A. ovatula (Kirby, 1802)); Ascher and Pickering (2023).

Remarks

We have not examined any specimens of this historically confused species (see Praz et al. 2022), but the presence of this species in Iraq is highly plausible based on its known global distribution, the map records indicated by Gusenleitner and Schwarz (2002), and the presence of this species in neighbouring Turkey and Iran where it is abundant.

Distribution

Somewhat unclear due to historical taxonomic confusion, but probably West and Central Palearctic (Praz et al. 2022; Wood and Monfared 2022; Ascher and Pickering 2023).

Andrena (Melandrena) albifacies Alfken, 1927

Literature records

Warncke (1969); Gusenleitner and Schwarz (2002: dot map 17); Grace (2010); Augul (2018); Wood and Monfared (2022); Ascher and Pickering (2023).

Remarks

We have not examined any specimens of this species, but the presence of this species in Iraq is highly plausible based on its known global distribution, the mention of this species from southern Iraq (Warncke 1969), the map records indicated by Gusenleitner and Schwarz (2002), and the presence of this species in neighbouring Iran.

Distribution

Morocco, Algeria, Tunisia, Libya, Egypt, Israel and West Bank, Jordan, Syria, Iraq, Iran (Warncke 1969; Gusenleitner and Schwarz 2002; Wood and Monfared 2022; Ascher and Pickering 2023).

Andrena (Truncandrena) albopicta Radoszkowski, 1874

Literature records

Gusenleitner and Schwarz (2002: dot map 18); Grace (2010); Augul (2018); Ascher and Pickering (2023).

Remarks

We have not examined any specimens of this species, but the presence of this species in Iraq is plausible: the species is present in south-eastern Turkey (see specimen records presented by Wood and Monfared 2022), and the dot map presented by Gusenleitner and Schwarz (2002) seems to indicate the presence of this species in northern Iraq. It is therefore tentatively accepted as present.

Distribution

Turkey, Armenia, Iraq, Iran (Gusenleitner and Schwarz 2002; Ascher and Pickering 2023), note that previous records from European Russia were erroneous, see Proshchalykin et al. (2023).

Andrena (Melandrena) albopunctata (Rossi, 1792)

Literature records

Gusenleitner and Schwarz (2002: dot map 19); Ascher and Pickering (2023).

Remarks

We have not examined any specimens of this species, but the presence of this species in Iraq is highly plausible based on its known global distribution, the map records indicated by Gusenleitner and Schwarz (2002), and the presence of this species in neighbouring Turkey and Iran.

Distribution

West and Central Palearctic (Gusenleitner and Schwarz 2002; Osytshnjuk et al. 2008).

Remarks and diagnosis

Wood (2023) described A. ayna from south-eastern Turkey (province of Hakkâri) based on two female specimens. Three male specimens from northern Iraq are now available. They are recognisable as Notandrena due to the short and broad head (Fig. 3B; 1.25× wider than long), the apex of the clypeus narrowed and slightly upturned, the at least partially yellow-marked clypeus, the broadened and weakly carinate gena (Fig. 3C; broader than the diameter of the compound eye), and the pronotum with a strong humeral angle. As in the female sex, A. ayna is immediately recognisable due to the sculpture of the scutum and scutellum which are almost entirely smooth and shiny over their entirely area, with scattered and sparse punctures (Fig. 3D).

Figure 3.

Description

Male. Body length: 6.5–7 mm (Fig. 3A). Head: Dark, 1.25× wider than long (Fig. 3B). Clypeus variably yellow-marked, from medial ½ with yellow spot which does not extend to lateral margins to almost entirely dark with small pale dot medio-apically. Clypeus broadly flattened medially, surface densely and shallowly punctate, punctures separated by 0.5–1 puncture diameter, surface dull; apical margin narrow, projecting, anterior margin slightly upturned, weakly emarginate. Process of labrum tiny, trapezoidal, slightly wider than long, surface polished and shining. Gena 1.5× wider than diameter of compound eye, posterior margin weakly carinate, surface covered with curved striations (Fig. 3C); ocelloccipital distance subequal to diameter of lateral ocellus. Head covered with sparse light brownish pubescence, hairs not equalling length of scape. Antennae basally dark, A4–13 ventrally lightened by presence of greyish-brown scales; A3 exceeding A4, shorter than A4+5.

Mesosoma : Scutum and scutellum polished and shining over almost entire surface, scutum weakly shagreened anteriorly; scutum with scattered irregular punctures, punctures separated by 1–5 puncture diameters, scutellum almost impunctate (Fig. 3D). Pronotum with strongly produced humeral angle, deep vertical furrow with surface shining, remaining lateral face of propodeum with longitudinal striations. Mesepisternum irregularly microreticulate, weakly shining. Dorsolateral parts of propodeum shagreened, weakly shining, sculpture overlain by network of irregular raised rugosity; propodeal triangle laterally defined by fine straight carinae, internal surface with network of rugae radiating from base, propodeal triangle not strongly differentiated from remaining propodeum. Mesosoma covered with sparse light brown hairs, none equalling length of scape. Legs dark, apical tarsal segments paler orange-brown, pubescence whitish. Hind tarsal claws with inner tooth. Wings hyaline, stigma and venation orange, nervulus antefurcal.

Metasoma : Tergal discs dark, marginal areas broadly lightened hyaline brown-white (Fig. 3E). Terga with sculpture variable, disc of T1 smooth and shining, T2–4 with base weakly shagreened, sculpture disappearing medially, tergal margins without sculpture. T1 with disc sparsely punctate, punctures separated by 2–3 puncture diameters, discs of T2–4 with punctures separated by 1–2 puncture diameters, marginal areas impunctate. Tergal discs with scattered pale hairs, not forming hairbands. T6–7 with light brown hairs overlying pseudopygidial plate. S8 columnar, short, apical margin truncate, ventral surface with sparse short brown hairs. Genital capsule compact, gonocoxae with inner margins almost forming rounded 90° angle, very weakly projecting (Fig. 3F). Gonostyli narrow basally, strongly broadening and flattened apically, inner margin raised, outer surface with short golden-brown hairs. Penis valves occupying ½ space between gonostyli, outer margins slightly thickened, progressively narrowing apically.

Distribution

South-eastern Turkey (Hakkâri) and northern Iraq* (Wood 2023).

Andrena (Notandrena) baiocchii Wood, sp. nov. *

Material examined

Holotype: Iraq: Duhok, Mt. Gara [S of Sarsing], 37.0158°N, 43.3506°E, 1912 m, 11.v.2023, 1♀, leg. D. Baiocchi, RMNH. Paratypes: Iraq: Same information as holotype, 5♀, MSVI/RMNH/TJWC/DUMAI.

Diagnosis

Andrena baiocchii can be recognised as part of the subgenus Notandrena Pérez, 1890 due to the dorsolateral angle of the pronotum with a strong transverse ridge (= pronotum with a strong humeral angle), dull impunctate terga (Fig. 4F; hence placing it closer to members of the former subgenus Carandrena Warncke, 1968), scutum with distinct but weakly shining to dull green-purple metallic reflections (Fig. 4D), hind tibiae which weakly but distinctly broaden medially and apically, resembling a crude isosceles triangle and covered with simple scopal hairs, and lack of any other distinctive characters. This combination of characters places it close to A. schlettereri Friese, 1896 (Central Europe to Turkey), A. purpureomicans Alfken, 1935 (Turkey), A. trimarginata (Radoszkowski, 1886) (= A. zostera Warncke, 1975; Middle East and Central Asia, see below), and A. aerinifrons Dours, 1873 sensu lato (Iberia, North Africa, and the Middle East). Andrea baiocchii can be separated from all these comparison species by the shape of the head which is almost round, only 1.1× wider than long (Fig. 4B; in comparison species is the head shorter, 1.2–1.4× wider than long) and the clypeus has contrasting surface sculpture, shagreened and weakly shining basally but becoming smooth and shining in its apical half AND with punctures becoming sparse, in the apical 1/3 of the clypeus with punctures separated by 1–3 puncture diameters (Fig. 4C). In comparison species the clypeus usually has a uniform sculpture, typically dull, never smooth and shining in its apical half (with the exception of A. trimarginata) and the clypeal punctures are consistently denser. Andrena trimarginata can be separated by the overall shape of the head (clearly wider than long) and by the density of clypeal punctures which are separated by a consistent 0.5–1 puncture diameters over the entire surface of the clypeus. Some individual species can also be separated with additional characters, as A. baiocchii has a small body size of 7–8 mm (usually 8–9 mm in A. aerinifrons), the propodeal triangle has a network of finely raised rugae covering ¾ of its surface (Fig. 4E; surface smooth in A. aerinifrons), and the tarsi are dark and the terga are completely impunctate (with the tarsi lightened orange and the terga with shallow but distinct punctures in A. purpureomicans). The male is unknown, but is expected to share the relatively elongate head which is unusual within this group of species.

Description

Female. Body length: 7–8 mm (Fig. 4A). Head: Dark, 1.1× wider than long (Fig. 4B). Clypeus domed, variably sculptured, in basal ½ with fine granular shagreen, weakly shining, in apical ½ smooth and shining, polished; surface punctate, punctures separated by 1–3 puncture diameters (Fig. 4C). Process of labrum small, rounded trapezoidal, 2× wider than long, apical margin weakly emarginate. Gena marginally exceeding diameter of compound eye; ocelloccipital distance equals ½ diameter of lateral ocellus. Foveae dorsally occupying slightly < ½ space between compound eye and lateral ocellus, slightly narrowing ventrally, separated from inner margin of compound eye by distance subequal to its own diameter; foveae filled with brown hairs. Face, gena, vertex, and scape with sparse light brown hairs, none equalling length of scape. Antennae basally dark, A5–12 ventrally lightened by presence of grey-orange scales; A3 slightly exceeding A4+5, slightly shorter than A4+5+6.

Mesosoma : Scutum and scutellum with dense fine granular microreticulation, weakly shining to dull, laterally and anteriorly with weak but distinct green-purple metallic reflections; surface irregularly and obscurely punctate, punctures separated laterally by 1–3 puncture diameters, medially by 3–5 puncture diameters (Fig. 4D). Pronotum with strong humeral angle. Mesepisternum and dorsolateral parts of propodeum with dense granular microreticulation, dull; propodeal triangle delineated by change in surface sculpture, predominantly covered with finely raised rugae over ¾ of its surface (Fig. 4E). Mesosoma with light brown hairs, longest on mesepisternum, not equalling length of scape. Propodeal corbicula incomplete, dorsal fringe composed of long plumose light brown hairs, internal surface with scattered light brown hairs. Legs predominantly dark, apical tarsal segments lightened brownish, pubescence light brown. Flocculus complete but relatively sparse, composed of light brown plumose hairs; femoral and tibial scopae composed of light brown-golden simple hairs. Hind tarsal claws with very small inner tooth. Wings hyaline, stigma bright orange, venation dark orange, nervulus antefurcal.

Metasoma : Terga dark, apical margins weakly but distinctly depressed, partially lightened brown; tergal discs with regular granular microreticulation, weakly shining, essentially impunctate, with very weak and sparse punctures disappearing into background sculpture (Fig. 4F). Terga with scattered short white hairs, not forming apical hairbands. Apical fringe of T5 and hairs flanking pygidial plate orange. Pygidial plate large, broadly rounded triangular, lateral margin weakly raised and impunctate, internal surface densely punctate, punctures separated by < 0.5 puncture diameters.

Male. Unknown.

Etymology

The species is named after Daniele Baiocchi who has collected insects across much of the Mediterranean basin and Middle East, and who led bee collection during the expedition to Duhok Governorate in May 2023.

Distribution

Iraq (Kurdistan region).

Andrena (Plastandrena) bimaculata (Kirby, 1802)

Literature records

Gusenleitner and Schwarz (2002: dot map 55); Scheuchl and Willner (2016); Ascher and Pickering (2023).

Remarks

We have not examined any specimens of this species, but the presence of this species in Iraq is highly plausible based on its known global distribution, the map records indicated by Gusenleitner and Schwarz (2002), and the presence of this species in neighbouring Turkey and Iran. We note however that the species concept of A. bimaculata is unclear, and all Old World members of the subgenus Plastandrena require revision using molecular markers. It should therefore be considered in a sensu lato at the present time.

Distribution

In a sensu lato, West and Central Palearctic to Mongolia (Gusenleitner and Schwarz 2002; Ascher and Pickering 2023).

Andrena (Cordandrena) cordialis Morawitz, 1878

Literature records

Morice (1921b); Derwesh (1965), mentioning “Survey of Iraq Fauna 1915–1919”; Augul (2018).

Material examined

Iraq: Baiji [Saladin Governorate, 35.0299°N, 43.4489°E], 1–31.iii.1986, 1♀, leg. M. Carl, OÖLM; Baiji, 1–30.iv.1986, 2♂, leg. M. Carl, OÖLM.

Remarks

Andrena cordialis is part of a tricky group of species to identify, with the species A. cypria Pittioni, 1950 and A. torda Warncke, 1965 described after the 1915–1919 survey was conducted. Morice (1921b) specifically mentioned the species from Basrah in southern Iraq. Based on our examined material, we can confidently confirm both A. cordialis and A. torda from Iraq, and so the record of Morice (1921b) is considered plausible. We note here that the “Survey of Iraq Fauna 1915–1919” is represented by the publications of Morice (1921a; 1921b), only Morice (1921b) dealing with the Andrena fauna.

Distribution

Eastern Europe through Turkey and the Caucasus to Central Asia, including Iraq and Iran (Gusenleitner and Schwarz 2002; Osytshnjuk et al. 2005; Wood and Monfared 2022)

Andrena (Poecilandrena) crassana Warncke, 1965 *

Material examined

Iraq: Duhok, Mt. Gara [S of Sarsing], 37.0158°N, 43.3506°E, 1912 m, 11.v.2023, 2♂, leg. D. Baiocchi, MSVI; Lebanon: Beqaa, Beqaa valley, Qaraoun, 3.5 km W of Madjal Balhis, 33.5377°N, 35.7038°E, 900 m, 4.iv.2023, 1♂, leg. T.J. Wood, TJWC.

Remarks

Specimens from Iraq nominally belong to A. crassana s. str. And the specimen from Lebanon nominally belongs to ssp. Inka Warncke, 1969 (Levant). It is not clear if inka merits subspecific status.

Distribution

Andrena crassana sensu lato has a distribution of North Macedonia, Greece, Turkey, Cyprus, Israel and West Bank, Lebanon*, Jordan, Syria, Iraq*, Iran (Gusenleitner and Schwarz 2002; Pisanty et al. 2018; Wood and Monfared 2022).

Andrena (Aciandrena) curviocciput Pisanty & Wood, 2022 *

Material examined

Iraq: Duhok, Mt. Gara [S of Sarsing], 37.0158°N, 43.3506°E, 1912 m, 11.v.2023, 12♂, leg. D. Baiocchi, MSVI/TJWC.

Andrena (Aciandrena) duhokensis Wood, sp. nov. *

Material examined

Holotype: Iraq: Duhok, Mt. Gara [S of Sarsing], 37.0158°N, 43.3506°E, 1912 m, 11.v.2023, 1♂, leg. D. Baiocchi, RMNH. Paratypes: Iraq: Same information as holotype, 7♂, MSVI/RMNH/TJWC/DUMAI.

Diagnosis

Andrena duhokensis can be recognised as part of the subgenus Aciandrena Warncke, 1968 due to the small body size, dark integument with the exception of the pale-marked clypeus (Fig. 5A), finely shagreened propodeal triangle (Fig. 5D; without lateral or basal rugae), more or less impunctate terga (Fig. 5E), strongly antefurcal nervulus, and typical simple genital capsule (Fig. 5F; e.g., without completely reduced gonocoxae as in most members of the subgenus Graecandrena Warncke, 1968). Identification of Aciandrena species is extremely challenging due to the large number of often cryptic species found in dry environments, their often very local distributions, and lack of good characters in the female sex. Fortunately, males are a little easier to identify through the examination of the genital capsule. Andrena duhokensis can be initially recognised due to its almost entirely yellow-marked clypeus (with the exception of two small black marks [sometimes absent] and some narrow black areas at the edges of the clypeus), placing it closest to A. tenuis Morawitz, 1877 which was described from the Caucasus. However, A. duhokensis can be recognised due to the unique form of the genital capsule which has the gonocoxal teeth with their apexes strongly truncate and asymmetrical so that they diverge from each other (Fig. 5F); in other words, they form somewhat pointed but flattened and diverging teeth. In comparative species of Aciandrena, the gonocoxal teeth are either strongly produced and truncate (e.g., A. deminuta Wood 2022 from Iran), produced into narrowly pointed or more broadly rounded teeth (e.g., A. tenuis from Turkey and the Caucasus, A. aciculata Morawitz, 1886 from Europe to the Caucasus), or reduced and truncate but never forming diverging teeth (e.g., A. judaea Scheuchl & Pisanty, 2016 from Israel). In this context, A. duhokensis can be separated from all similar species.

Description

Female. Unknown.

Male. Body length 4–5 mm (Fig. 5A). Head: Dark, 1.25× wider than long (Fig. 5B). Clypeus weakly domed, predominantly yellow or pale yellow marked with exception of two black dots (sometimes absent) and narrow black markings laterally; surface finely shagreened and weakly shining, irregularly punctate, punctures separated by 1–3 puncture diameters. Process of labrum small, rounded trapezoidal, 2× wider than long, apical margin weakly emarginate. Gena subequal to diameter of compound eye; ocelloccipital distance equals diameter of lateral ocellus. Head covered with dirty white hairs, none equalling length of scape. Antennae basally dark, A4–13 ventrally lightened by presence of grey scales; A3 exceeding length of A4, shorter than A4+5; A4 sub-square, shorter than long, A5 quadrate, as long as broad.

Mesosoma : Scutum and scutellum with fine granular shagreen, weakly shining, irregularly punctate, punctures separated by 1–4 puncture diameters (Fig. 5C). Mesepisternum and dorsolateral parts of propodeum with regular but large microreticulation, dull to weakly shining; propodeal triangle large, indicated by change in surface sculpture, internal surface with fine granular microreticulation, in some parts with weakly raised network of carinae between microreticulation, surface dull (Fig. 5D). Mesosoma with sparse short whitish hairs. Legs predominantly dark, apical tarsal segments slightly lightened orange, pubescence white. Hind tarsal claws with strong inner tooth. Wings hyaline, stigma, and venation pale orange, nervulus very strongly antefurcal.

Metasoma : Terga predominantly dark, tergal margins weakly but distinctly depressed, broadly lightened hyaline yellow-brown (Fig. 5E). Tergal discs finely microreticulate to shagreened, weakly shining, surface essentially impunctate, with scattered obscure punctures disappearing into underlying sculpture. Terga with sparse scattered short hairs, not forming hairbands. T6 and T7 with long light brown hairs overlying pseudopygidial plate of T7. S8 narrow, apex slightly broadened like a fish-tail, truncate, ventral surface with dense lateral fan of brown hairs. Genital capsule compact, gonocoxae produced into apical teeth, teeth strongly truncate, apexes angled and diverging from each other to form angular anteriorly projecting teeth (Fig. 5F). Gonostyli flattened and spatulate, internal margins raised, forming slight bump on inner margin basally. Penis valves moderate, occupying ½ space between gonostyli basally, strongly tapering apically.

Etymology

The name is derived from the city of Duhok which gives its name to the province in which these specimens were collected.

Distribution

Iraq (Kurdistan region).

Andrena (Micrandrena) elam Wood, 2022 *

Material examined

Iraq: Duhok, Mt. Gara [S of Sarsing], 37.0158°N, 43.3506°E, 1912 m, 11.v.2023, 23♂, 1♀, leg. D. Baiocchi, MSVI/TJWC.

Remarks and diagnosis

Wood in Wood and Monfared (2022) described A. elam in the female sex from western and southern Iran, and Wood (2023) reported further specimens from southern and south-eastern Turkey. Numerous male specimens from northern Iraq are now available. They can be recognised as Micrandrena due to the small body size, dark integument (including clypeus Fig. 6B), entirely rugose propodeal triangle (Fig. 6D), and normal genital capsule. As in the female sex, they can be separated from other Micrandrena species by the combination of smooth and shining scutum and scutellum with moderately dense punctures (Fig. 6C), the tergal discs with extremely strong and dense reticulation (Fig. 6E), this reticulation becoming much weaker on the marginal areas, with punctures visible on the discs of T3–4 (though comparatively weaker and less visible than in the female), and by the tergal margins becoming progressively more strongly depressed. Additionally, the genital capsule is distinctive (Fig. 6F), somewhat elongate, with the gonocoxae produced into weak angular teeth, with thickened gonostyli with a weak rounded bump on their inner margins and outer surface lightened and covered with short golden hairs. It resembles the form of two former Fumandrena (= Micrandrena) species (A. fabrella Pérez, 1895 (western Mediterranean) and A. tomora Warncke, 1975 (eastern Mediterranean)), but these have the gonostyli apically flattened, not thickened. It is very close to A. subviridula Wood, 2022 (northern Iran, see illustrations in Wood and Monfared 2022), but can be separated by the gonocoxae produced into apical points (in A. subviridula with the gonocoxae apically truncate), by the weaker bump on the inner margins of the gonostyli (in A. subviridula with this bump comparatively more pronounced), and by the more extensively shiny scutum which lacks subtle greasy green-metallic reflections (in A. subviridula with the scutum more extensively shagreened anteriorly and laterally).

Figure 6.

Description

Male. Body length: 6 mm (Fig. 6A). Head: Dark, 1.45× wider than long (Fig. 6B). Clypeus domed, densely punctate, punctures separated by < 0.5–1 puncture diameter, surface with weakly raised latitudinal striations between punctures, surface weakly shining. Process of labrum trapezoidal, 2× wider than long, anterior margin weakly emarginate, surface smooth and shining. Gena equalling diameter of compound eye; ocelloccipital distance equalling diameter of lateral ocellus. Head with sparse whitish hairs, none equalling length of scape; clypeus in fresh individuals with moderate “beard” of ventrally projecting pale hairs. Antennae dark, A5–13 ventrally lightened by presence of silver-grey scales; A3 exceeding length of A4, shorter than A4+5.

Mesosoma : Scutum and scutellum polished and shining over almost entire surface, scutum weakly shagreened anteriorly; irregularly punctate, punctures separated by 1–3 puncture diameters (Fig. 6C). Pronotum rounded. Mesepisternum microreticulate, dull. Dorsolateral parts of propodeum microreticulate, dull, sculpture overlain by network of irregular raised rugosity; propodeal triangle laterally defined by irregular carinae, internal surface densely covered with network of evenly-spaced rugae, propodeal triangle thus well-differentiated from dorsolateral parts of propodeum (Fig. 6D). Mesosoma covered with sparse light brown hairs, none equalling length of scape. Legs dark, apical tarsal segments paler dark brown, pubescence whitish. Hind tarsal claws with inner tooth. Wings hyaline, stigma dark brown, venation orange-brown, nervulus interstitial.

Metasoma : Tergal discs dark, marginal areas with apical rim narrowly lightened brown (Fig. 6E). Tergal discs strongly reticulate, reticulation strongest on T1, surface dull, becoming progressively weaker on subsequent terga, discs of T5 and T6 weakly shining; marginal areas shagreened, weakly shining. Tergal discs obscurely punctate, T1 almost impunctate, punctures progressively more visible on subsequent terga, punctures on disc of T4 separated by 1–2 puncture diameters. Tergal discs with scattered pale hairs, not forming hairbands. T6 and T7 with light brown hairs overlying pseudopygidial plate. S8 columnar, apical margin truncate, ventral surface with sparse short brown hairs. Genital capsule somewhat elongate, gonocoxae with apical margins produced into slightly projecting narrow apical teeth (Fig. 6F). Gonostyli robust, thickened, with weak bump on internal margins basally, apically weakly flattened, apical ½ lightened hyaline yellowish. Penis valves narrow, occupying ½ space between gonostyli, uniformly narrowing towards apex.

Remarks

The original female specimens described by Pisanty et al. (2016) actually belonged to A. gageae Wood & Pisanty, 2022 (see Pisanty et al. 2022a). The true female of A. hermonella is being described from south-eastern Turkey (Wood, in press). This extends the range from south-eastern Turkey into northern Iraq.

Remarks

The specimens presented here appear to be A. hyemala s. str. The statuses of the subspecies repressa Warncke, 1975 (Levant) and kushika Osytshnjuk, 1994 (Central Asia) require further study.

Distribution

Andrena hyemala sensu lato is distributed from south-eastern Europe through the Middle East (including Iraq* and Iran) to Central Asia (Gusenleitner and Schwarz 2002; Osytshnjuk et al. 2008; Wood and Monfared 2022).

Remarks

The finding of A. kriechbaumeri in Iraq is notable. One of the most common and abundant Andrena species in the southern Balkans, A. kriechbaumeri is much less common in Turkey where it is largely restricted to western Turkey (see distribution map of Gusenleitner and Schwarz 2002). Examination of undetermined material in the OÖLM collection produced specimens from northern Syria and a specimen from near to Siirt in eastern Turkey. To our knowledge, this is the most easterly specimen known from Turkey. In this context, the presence of A. kriechbaumeri in northern Iraq represents less of an outlier, though it is clear that A. kriechbaumeri has a population centre in the Balkan Peninsula.

Distribution

Europe from Italy to Turkey, Syria*, and Iraq* (Gusenleitner and Schwarz 2002).

Remarks and diagnosis

Wood and Monfared (2022) described A. obsidiana in the female sex from southern and south-eastern Turkey and western and southern Iran. Numerous male specimens from northern Iraq are now available, as well as some additional specimens from south-eastern Turkey that were not available for study at the time of the original description. One of these A. obsidiana specimens from Turkey (a female) was separated by Warncke and labelled as “A. ferulella spec. nov.”, but this name was never published.

Andrena obsidiana can be recognised as Micrandrena due to the small body size, dark integument (including clypeus Fig. 7B), entirely rugose propodeal triangle (Fig. 7D), and normal genital capsule (Fig. 7F). Due to the smooth and shining scutum and scutellum with moderately dense punctures (Fig. 7C) and the genital capsule (gonocoxae produced into weak angular teeth, with thickened gonostyli with very small rounded bump on their inner margins, and outer surface lightened and covered with short golden hairs) it is close to A. elam and A. subviridula, but it can instantly be separated from them by the sculpture of the terga which is almost completely smooth and shining (Fig. 7E), with only superficial shagreenation at the base of the tergal discs. There are also differences in the genital capsule, with that of A. obsidiana being comparatively more elongate, with the bump on the inner margin of the gonostyli reduced to a relatively tiny projection.

Turkey, Israel and West Bank, Lebanon, Jordan, Syria, Iraq*, Iran (Wood et al. 2020; Wood and Monfared 2022).

Andrena (Suandrena) savignyi Spinola, 1838

Literature records

Moalif (1994); Ascher and Pickering (2023).

Remarks

We have not examined any specimens of this species, but the listing is plausible due to the presence of multiple specimens of A. savignyi in western and southern Iran (Wood and Monfared 2022), and the preference of A. savignyi for dry desert and semi-desert habitats.

Distribution

West and Central Palaearctic (Wood and Monfared 2022; Ascher and Pickering 2023).

Andrena (Micrandrena) sillatahistrionica Warncke, 1975 *

Material examined

Iraq: Duhok, Mt. Gara [S of Sarsing], 37.0158°N, 43.3506°E, 1912 m, 11.v.2023, 4♂, 1♀, leg. D. Baiocchi, MSVI.

Distribution

Subspecies histrionica is found in Turkey, Iraq*, and Iran only (Wood and Monfared 2022). It may merit species status due to differences in the male genital capsule, but genetic data are required.

Remarks

Confirmed as present in Lebanon after the unclear listing of Grace (2010).

Distribution

Remarks

The status of A. tadorna callida is unclear and requires investigation; it may well merit species status due to consistent differences in the shape of the genital capsule (see comments in Gusenleitner and Schwarz 2002).

Distribution

Andrena tadorna sensu lato is found in Morocco, Algeria, Tunisia, Libya, Egypt, Israel, Jordan, Syria*, Saudi Arabia*, Iraq* Gusenleitner and Schwarz (2002).

Remarks

Records from Lebanon, Jordan, and Syria reported by Wood et al. (2020) were incorrectly identified female specimens of A. cypria (see Wood and Monfared 2022), with females of A. torda and A. cypria being challenging to separate morphologically. The female Lebanese specimens presented here were confirmed as A. torda through DNA barcoding (BIN: BOLD:AES5002) as distinct from A. cypria (BIN: BOLD:AFH0814), this latter BIN containing a barcoded male specimen of A. cypria which can be unambiguously recognised due to the combination of its antennal segment ratios and genital capsule.

Distribution

Greece, Turkey, Cyprus, Israel and West Bank, Lebanon*, Iraq*, Iran (Wood and Monfared 2022).

Andrena (Notandrena) trimarginata (Radoszkowski, 1886)

Literature records

Wood and Monfared (2022, as A. zostera Warncke, 1975).

Material examined

Lebanon: Balbek-Hermel, Sefri, Haouch Snaid, AUB farm, 33.9244°N, 36.0754°E, 1000 m, 6.iv.2023, 4♂, leg. T.J. Wood, TJWC.

Remarks

A taxonomic work will soon recognise Halictus trimarginatus Radoszkowski, 1886 (described from Turkmenistan) as the senior name of A. zostera (Wood, in press).

Distribution

Israel and West Bank, Syria, Lebanon*, Turkey, Azerbaijan, Iraq, Iran, Turkmenistan, Uzbekistan, Tajikistan (Osytshnjuk et al. 2005 as A. subsmaragdina Osytshnjuk, 1984; Wood and Monfared 2022).

Andrena (Aciandrena) turmalina Pisanty & Wood, 2022 *

Material examined

Iraq: Duhok, Bessre [Besereh], Bablo, 36.8675°N, 43.1206°E, 1065 m, 5–6.v.2023, 1♀, leg. D. Baiocchi, MSVI; Duhok, Mt. Gara [S of Sarsing], 37.0158°N, 43.3506°E, 1912 m, 11.v.2023, 4♂, 5♀, leg. D.

Remarks

As suspected by Pisanty et al. (2022a), A. turmalina is also present in Lebanon.

Distribution

Israel, Lebanon*, Turkey, Iraq*, Iran (Pisanty et al. 2022a).

Andrena (Holandrena) variabilis Smith, 1853

Andrena bakrajoensis Amin & Mawlood, 2019, syn. nov.

Literature records

Amin and Mawlood (2019, as A. bakrajoensis)

Remarks

Amin and Mawlood (2019) described A. bakrajoensis from Bakrajo in Iraqi Kurdistan. They diagnosed it against A. (Simandrena) vetula Lepeletier, 1841, but based on the description and the provided photographs it is clearly a member of the subgenus Holandrena Pérez, 1890 due to the predominantly declivous propodeum (almost without a dorsal horizontal area), strong tergal hairbands, and compact body with rounded head. Based on the long ocelloccipital distance (3× the diameter of a lateral ocellus), it can only be a single species, A. variabilis. Andrena bakrajoensis is therefore synonymised with A. variabilis. The distribution maps of Gusenleitner and Schwarz (2002) do not positively indicate the presence of A. variabilis in Iraq, though some dots are present around the Tigris and Euphrates deltas in southern Iraq. However, A. variabilis is a widely distributed species in Turkey and Iran (Gusenleitner and Schwarz 2002; Wood and Monfared 2022), and so its presence in Iraq is expected and demonstrated through this synonymy.

Andrena (Planiandrena) veterana Pisanty, 2022 *

Material examined

Iraq: Duhok, Mt. Gara [S of Sarsing], 37.0158°N, 43.3506°E, 1912 m, 11.v.2023, 1♀, leg. D. Baiocchi, MSVI; Lebanon: Beqaa, Rachaiya, 5 km S, Mount Hermon nature reserve, 33.4586°N, 35.8395°E, 1500 m, 8.iv.2023, 10♀, leg. T.J. Wood, TJWC.

Remarks

These records markedly expand the range of A. veterana which was described from Mount Hermon (Pisanty et al. 2022a).

Distribution

Israel, Lebanon*, Iraq* (Pisanty et al. 2022a).

Andrena (Simandrena) vetula Lepeletier, 1841

Literature records

Morice (1921b); Derwesh (1965), mentioning “Survey of Iraq Fauna 1915–1919”; Gusenleitner and Schwarz (2002: dot map 504); Augul (2018); Ascher and Pickering (2023).

Remarks

We have not examined any specimens of this species, but the presence of this species in Iraq is highly plausible based on its known global distribution, the map records indicated by Gusenleitner and Schwarz (2002), and the presence of this species in neighbouring Turkey and Iran.

Distribution

West and Central Palearctic (Gusenleitner and Schwarz 2002; Wood and Monfared 2022; Ascher and Pickering 2023).

Andrena (Poecilandrena) viridescens Viereck, 1916

Literature records

Morice (1921b); Derwesh (1965), mentioning “Survey of Iraq Fauna 1915–1919”, as A. cyanescens Nylander, 1852 nec. Haliday; Augul (2018).

Material examined

Iraq: Duhok, Mt. Gara [S of Sarsing], 37.0158°N, 43.3506°E, 1912 m, 11.v.2023, 5♂, leg. D. Baiocchi, MSVI/TJWC.

Remarks

Members of the subgenus Poecilandrena Hedicke, 1933 are challenging to identify (e.g., Pisanty et al. 2018), but we can confirm the record of Morice (1921b) through the examination of newly collected material.

Distribution

Europe to Turkey, Iraq, Iran (Gusenleitner and Schwarz 2002; Wood and Monfared 2022).

Species excluded

Andrena (Melandrena) sigiella Gusenleitner, 1998

Literature records

Grace (2010); Augul (2018); Ascher and Pickering (2023).

Remarks

We have examined no specimens of this species from outside of the Levant (Israel and West Bank, Jordan, Lebanon, Syria; Wood et al. 2020). Neither Grace (2010) or Augul (2018) report precise specimen records and, pending further investigations, we exclude A. sigiella from the list of Iraqi Andrena as if truly present it would be a considerable range extension from the Levant.

Andrena (Suandrena) leucocyanea Pérez, 1895

Literature records

Dylewska (1983).

Remarks

Dylewska (1983: 22) revised members of the subgenus Suandrena Warncke, 1968, mentioning A. leucocyanea from Iraq from Abu Ghuraib [= Abu Ghraib] and Dewania [= Al Diwaniyah]. Given the many taxonomic changes that have occurred in this subgenus since 1983 (e.g., Kratochwil 2021; Pisanty et al. 2022a) and its difficulty of identification, it is unclear what these specimens might actually be. Consequently, we exclude this species from the Iraqi fauna pending inspection of material in light of the currently accepted taxonomic framework for this subgenus.

Discussion

As a measure of its chronic lack of study, the updated faunal list presented here for Iraqi Andrena totals some 59 species, a tiny fraction of the 215 and 388 species known from neighbouring Iran and Turkey, respectively (Wood and Monfared 2022; Wood 2023; Wood, unpublished data), and even of the 154–166 species known from neighbouring Syria. Moreover, to the best of our knowledge, the current work represents the first country records for 42 of the 59 Iraqi Andrena species reported here. Indeed, the collection around Duhok in May 2023 produced 38 new country records just for Andrena, including the two new species for science. Of these 38 new country records, 12 of these species have been described since 2016, highlighting that not only is Iraq understudied in general, but that it specifically hosts a special Andrena fauna containing range-restricted species that has received relatively little attention until recently.

The increase from 17 to 59 Andrena species represents a 347% increase in species richness. Should it be applied equally across the entire Iraqi bee fauna, the 101 species listed by Ascher and Pickering (2023) would become 350. Though this is a crude approach, this produced total is plausible and seems reasonable given the huge diversity of bee species known to occur in Turkey (1,786 species as listed by Ascher and Pickering 2023). If anything, it is likely to be an underestimate. Based on the initial determination of other Iraqi bee groups, we will soon report faunal increases of 380% for Eucera (Apidae), ~ 666–833% for osmiine bees (Megachilidae), and an estimated 430–530% increase for Nomada (Apidae) (M. Selis, unpublished data). When dealing with such a poorly studied but likely species-rich fauna, these massive increases indicate a consistent pattern. We hope that this first focused revision of Iraqi Andrena can serve as a model to promote further studies into the Iraqi bee fauna.
