Diagnosis
Andrena rostamiae sp. nov. is challenging to place. It is partly similar to previously described species of Planiandrena because of the short and broad process of the labrum (Fig. 129) and the similarly sculptured though significantly wider clypeus (Fig. 128) that is wider than long (vs as wide as long or longer than wide in A. flagrans sp. nov., A. huma sp. nov., and A. sella sp. nov.). However, the foveae are substantially wider dorsally, occupying nearly half of the distance between the compound eye and the lateral ocellus (Fig. 130) (vs not occupying more than ¼ of this distance in the three comparison species). The pygidial plate is also flat and the hind tibial spur is unbroadened. It is therefore similar to A. hulae Pisanty, 2022 from northern Israel, which is also not possible to place in a subgenus at this time. Andrena rostamiae can be separated by the dark antennae (vs antennal segments 5–12 lightened orange below), the flattened clypeus (vs clypeus domed), the shorter ocelloccipital distance that is subequal to the diameter of a lateral ocellus (vs slightly greater than the diameter of a lateral ocellus), the smoother propodeal triangle that lacks basal rugae (vs propodeal triangle with short longitudinal basal rugae), and the impunctate scutum and scutellum (vs shallowly but distinctly punctate). Until male material is available, no firm decision on subgeneric placement is taken.
Etymology
Named after Ehlam Rostami, who collected many of the new species described in this manuscript.

Description
Female
MEASUREMENTS. Body length 8.5–9.5 mm (Fig. 127).
HEAD. 1.3 times as wide as long. Clypeus dark, broad, 1.5 times as broad as long, weakly flattened over majority of its area, covered with weak and irregular punctures, punctures separated by 1–4 puncture diameters; individual punctures slightly elongated latitudinally; poorly defined longitudinal impunctate line formed centrally (Fig. 128). Clypeus surface basally and laterally with fine, slightly raised microreticulation, forming latitudinal wrinkles; becoming weaker centrally and apically, here weakly shining. Process of labrum rectangular, short and broad, 4 times as wide as long; apical margin weakly and shallowly emarginate (Fig. 129). Face, gena, vertex, and scape with long whitish to light brownish hairs, not exceeding length of scape. Gena equalling width of compound eye; ocelloccipital distance small, just over ½ diameter of lateral ocellus. Fovea dorsally broad, occupying ½ of space between compound eye and lateral ocellus, medially slightly constricted, separated slightly from inner margin of compound eye; foveae filled with light brown hairs (Fig. 130). Antennae dark, A3 slightly exceeding A4+5, distinctly shorter than A4+5+6.
MESOSOMA. Scutum with dense granular microreticulation, dull, essentially impunctate; scutellum with similar but slightly weaker sculpturing, very weakly shining (Fig. 131). Pronotum with weak humeral angle, dorsolateral angle pronounced dorsally but becoming rounded ventrally, obscure. Mesepisternum, lateral and dorsolateral faces of propodeum with granular microreticulation, weakly shining. Propodeal triangle broad, laterally defined by narrow dark line lacking granular microreticulation, internal surface with same granular microreticulation as dorsolateral faces of propodeum, becoming coarser basally. Mesosoma covered in whitish hairs laterally and ventrally, becoming light brownish dorsally; propodeal corbiculae with light brownish weakly plumose hairs, internal surface with simple light brownish hairs. Legs dark, apical tarsal segments lightened dark brown, pubescence brownish-white to dark brown; tibial scopae light brownish, femoral scopae and flocculus white. Hind tarsal claws with inner tooth. Hind tibial spur parallel-sided. Wings hyaline, stigma orange, venation dark orange, nervulus antefurcal; first recurrent vein enters second submarginal cell very strongly beyond its middle.
METASOMA. Terga dark, marginal areas of T2–4 very weakly depressed, marginal areas of T1–4 lightened dark brown to narrowly yellow-hyaline apically (Fig. 132). Terga densely and finely microreticulate; microreticulation becoming weaker from mid-point of T3 onwards; overall, terga dull to weakly shining apically. T1–3 essentially impunctate, disc of T4 with obscure scattered punctures. T2–4 with weak apical hair fringes, broadly interrupted on T2–3, complete on T4. Fringe of T5 and hairs flanking pygidial plate golden orange; pygidial plate broadly rounded apically, flattened, internal surface with dense scalelike microreticulation, strongly delineated by impunctate rim.
Male
Unknown.
Remarks
All specimens were collected from Acer monspessulanum in April.
Distribution
Southern Iran (Yasouj).
