The three genera are members of the subfamily Syrphinae, where nearly all members feed as larvae on soft-bodied Hemiptera and other arthropods. Phytophagous species have recently been discovered in two subgenera of Allograpta, sg Fazia and a new subgenus from Costa Rica. Phylogenetic analyses of the combined datasets were performed using parsimony, under static alignment and direct optimization, maximum likelihood and Bayesian inference. Congruent topologies obtained from all the analyses indicate paraphyly of the genus Allograpta with respect to Sphaerophoria and Exallandra. Exallandra appears embedded in the genus Sphaerophoria, and both genera are placed within Allograpta. The distribution of phytophagous taxa in Allograpta indicates that plant feeding evolved at least twice in this group.</p>
