	abstract = {The genus Merodon Meigen, 1803 (Syrphidae, Diptera), with more than 50 European species, is primarily distributed in the Mediterranean region, there being 34 species that occur in the Iberian Peninsula. The morphological variation found within some species from the Iberian Peninsula prompted us to test their taxonomic status by integrating morphological and molecular data. We generated partial sequences of the mitochondrial, protein-coding gene cytochrome c oxidase subunit I (COI), the nuclear, internal transcribed spacer (ITS2) region, and the D2 region of the nuclear 28S rRNA gene. COI and ITS2 sequences were obtained for most included taxa. The variability of the COI sequences showed great differences between the studied species groups, exhibiting an interspecific range from 0.29\% to 12.5\% between ingroup taxa. Closely related taxa of the aureus complex (e.g. M. quercetorum and M. legionensis) presented identical COI sequences. The obtained ITS2 sequences showed low intraspecific variability, and only a few taxa presented more than one genotype. Species status and delimitation were discussed for all taxa in the light of available morphological and molecular character information. Using the obtained sequence data for COI and 28S we inferred the phylogenetic relationships of the included taxa, using parsimony analysis. Separate analysis of the COI sequences identified four, quite wellsupported clades within Merodon, the desuturinus, albifrons, nigritarsis and aureus groups. Combined analysis of the COI and 28S genes produced a topology similar to the COI topology.},

	abstract = {<p>Phylogenetic relationships of genera Allograpta, Sphaerophoria and Exallandra (Diptera, Syrphidae) were analyzed based on sequence data from the mitochondrial protein-coding gene cytochrome c oxidase subunit I (COI) and the nuclear 28S and 18S ribosomal RNA genes. 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>
