Metasoma black; 1 st and sometimes 2 nd tergites with basal yellow bands or spots; 1 st to 4 th tergites with wide apical yellow bands. In Iranian specimen, 5 th to 7 th tergites laterally and hypopygium entirely reddish. Coxae and trochanters black, with ± distinct yellow spots; trochantelli yellow. Fore and mid legs mainly yellow. Hind femur red, apically yellow; hind tibia reddish internally and yellow externally; hind tarsus brown or black. Fore wing with weak brown apical spot;
