Material examined.

Iraq: Duhok, Mt. Gara [S of Sarsing], 37.0158 ° N, 43.3506 ° E, 1912 m, 11. v. 2023, 3 ♂, leg. D. Baiocchi, MSVI / TJWC .

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. 3 B ; 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. 3 C ; 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. 3 D ).

Description.

Male. Body length: 6.5–7 mm (Fig. 3 A ). Head: Dark, 1.25 × wider than long (Fig. 3 B ). 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. 3 C ); ocelloccipital distance subequal to diameter of lateral ocellus. Head covered with sparse light brownish pubescence, hairs not equalling length of scape. Antennae basally dark, A 4–13 ventrally lightened by presence of greyish-brown scales; A 3 exceeding A 4, shorter than A 4 + 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. 3 D ). 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. 3 E ). Terga with sculpture variable, disc of T 1 smooth and shining, T 2–4 with base weakly shagreened, sculpture disappearing medially, tergal margins without sculpture. T 1 with disc sparsely punctate, punctures separated by 2–3 puncture diameters, discs of T 2–4 with punctures separated by 1–2 puncture diameters, marginal areas impunctate. Tergal discs with scattered pale hairs, not forming hairbands. T 6–7 with light brown hairs overlying pseudopygidial plate. S 8 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. 3 F ). 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.
