D i a g n o s i s: A. vanharteni belongs to the A. mesostenus lineage and can be recognized by the following character combination: T 1 is red and has apically a complete yellow band before the transparent apical margin. Body colour is whitish yellow. T 1 is longer than in remaining species (see key for details).

D e s c r i p t i o n o f h o l o t y p e, f e m a l e: Body length 8.0 mm. Colour: whitish yellow are: Basal half of mandible, labrum, clypeus, space below antennal socket, short band on lower eye margin, AS I-III, pronotal lobe, spot each on mesoscu- tum laterally in basal and apical corner, metanotum, apical band on T 1, medially with Vshaped interruption, bands on T 2- T 5, bands on tergites IV and V does not reach tergal margin, triangular spot on S2, apical part of fore- and midfemora, tibiae, tarsi. AS X-XII, basal half of fore- and midfemora, hindfemora and large spot on innerside of hindfemora apically reddish. Apical half of hindtarsomere V and claws black. Wing venation reddish, wings transparent. Morphology: Face including clypeus and vertex, lower mesopleuron and propodeal declivity with dense, silver pilosity, T 1 1.3x, mesoscutum with coarse punctation, punctures 0,3-3 diameters apart. Otherwise similar to M. mesostenus (see PULAWSKI 1973). Paratype females agree with holotype.

D e s c r i p t i o n o f m a l e: Body length 7.0-8.0 mm. Agree in general aspects with the female. Yellow band on T 1 large, T 7 with medial yellow spot. T 1 1.7x as long as maximum width. Yellow colour pattern of mesosoma variable: most males with lateral band on mesosoma in whole length, pronotal apex with thin band, scutellum with medial spot or band. Male from Oman has mesosoma and scutellum black.

E t y m o l o g y: The species is named in honour of Antonius v. Harten, for his enormous contribution to the knowledge of Hymenoptera and other arthropods in the United Arab Emirates.
