Nadimi et al. (2014) also mention Peykanshahr (35°44’N, 51°09’E) and Pishva-Mohammad Abad (35°15’N, 51°44’E) in northern Iran as “ A. cf. rotundum   ”. A male in OLL is labelled as “ Anthidium   flavitarse. Serbien: Rndow”, without date or collector. The locality could not be identified and the record needs confirmation GoogleMaps   .

Diagnosis. The female is characterised by a deeply concave vertex (moderately concave in the other species) which is slightly curled up in lateral view (lamellate in A. preoccipitale   , rounded to angular in the other species). Clypeus is flat with a broad (approx. one antenna diameter wide) impunctate middle line (shared with A. anguliventre   ; narrower middle line in the other species). Terga with a narrow (1–2 puncture diameter wide) smooth marginal zone (punctation reaching apical margin in all other species). See Table 1 for further characters.

The male of A. rotundum   is well characterised by the semicircular T6, not flattened or emarginated at the apex as in the other species of the subgenus, and an angulate vertex (lamellate or rounded in the other species). Yellow band on T1 mostly broadly interrupted (uninterrupted in the other species). Anthidium rotundum   has a characteristic S6 with a median longitudinal furrow. Anthidium rotundum   is on average larger than the other species.

Description. Female. 9–12 mm. Head: Clypeus ( Fig. 7D View FIGURE 7 ) flat with a broad almost entirely impunctate, smooth middle band; anterior and posterior margins straight, posterior margin smooth and bulging, and with a narrow, semitransparent light brown apex; supraclypeal area yellow, with scattered punctation; paraocular area yellow, with a broad band almost reaching top of eye; mandible yellow with five dark brown teeth, and sometimes an additional minute tooth distal to the uppermost; vertex slightly curled up, preoccipital ridge angular; vertex in dorsal view deeply concave ( Fig. 10B View FIGURE 10 ); yellow preoccipital band; gena yellow except for some black on the inner side.— Mesosoma: Black   with broad yellow, reverse U-shaped band; mesepisternum yellow with very low omaular lamella; pronotal lobe yellow with high lamella; scutellum widely rounded in dorsal view with posterior semi-transparent margin laterally; posterior margin of axilla set back against posterior margin of scutellum; scutellum and axilla yellow, with black base of scutellum.— Metasoma: Discs of T1–T5 yellow, depressions black; punctation on depressions finer than on discs, punctures leave an impunctate posterior margin; T6 yellow (except of some black laterally), depressed as seen in profile; small sting-wide incision at apex.— Legs: Yellow; hind tibia rounded; hind basitarsus with strong carina.

Male. 9–14 mm. Head: Clypeus flat with straight basal and lateral margins; broadly impunctate medially, apical margin with a thin semi-transparent end line; very shallowly emarginate; dense punctation laterally; mandible yellow with 3 black teeth; supraclypeal area yellow with scattered punctation; paraocular area yellow, with yellow maculation reaching upper end of eye; vertex strongly concave in dorsal view with angulate margin ( Fig. 10B View FIGURE 10 ); yellow preoccipital band reaching mandibles; preoccipital band sometimes interrupted medially with some yellow remnants in the middle; gena broad, broader than eye in lateral view; scape dark yellow; proximal segments of antenna ochreous.— Mesosoma: Scutum   black with yellow, inverted U-shaped yellow band; inner arm much thinner than lateral arm; scutellum widely rounded in dorsal view, somewhat overhanging propodeum; apical margin emarginate in the centre; scutellum and axillae yellow except at the base of scutellum; pronotal lobe yellow with high lamella; mesepisternum with yellow maculation; upper part of omaulus slightly carinate, but hardly visible because of dense white pubescence.— Metasoma: T1–T6 with yellow bands, mostly interrupted on T1, otherwise uninterrupted; T2 bulged laterally, T3 with rounded lateral projection, T4–T6 with acute projections; apical margin of T6 bulged; T7 yellow, semicircular, with fine longitudinal carina medially and transparent apical margin ( Figs 8E View FIGURE 8 , 9C View FIGURE 9 ); S6 semicircular with median furrow, broadening towards the apex, and a lateral depression ( Fig. 9F View FIGURE 9 ).— Legs: Femora with much black maculation; tibiae yellow with black inner face; tarsi yellow.— Hidden sterna and genitalia: S7 elongate with hairy apex; S8 with triangular apex; apex of penis valves spearhead-like. See also separate chapter.

Biology. All records are from June and July. According to Müller (1996), Cardueae (Asteraceae)   are the ex- clusive pollen sources of A. rotundum   . The species was collected in Lebanon from Centaurea sp.   (M. Boustani, unpubl.), and in Iran from Centaurea bruguierana ( Dehghan Dehnavi et al., 2014)   .

Distribution. Known from Greece, Iran, Lebanon, Syria, Turkey, and Azerbaijan ( Fig. 16 View FIGURE 16 ). A record from Morocco (van den Zanden, 1996) seems to be unreliable and records from Egypt (van den Zanden, 1996) need confirmation. The distribution in the west extends to Lesbos (northern Aegean; Grace, 2010) and western Anatolia (Izmir and Muğla) provinces).
