It is obviously monophyletic, but its relationships remain uncertain. • Atherigona Rondani, 1856 ( Fig. 11A–B ) A total of 20+ named and unidentified species of Atherigona from the Old World tropics and Mediterranean subregion were examined. They invariably share state A0 , in which vein C is wholly bare ventrally behind the lower anterior row of alternating spinules and setulae, as exemplified by A. orientalis Schiner, 1868 ( Fig. 11A–B ).
