Abstract
A phylogenetic analysis of the subfamily Mirinae was conducted based on 89 external and genitalic morphological characters. Forty-six species belonging to 30 genera were coded and phylogenetic analysis reconstructed using un-weighted (EW) and implied weighted (IW) characters in a parsimony analysis. This resulted in the monophyly of eight genera including Stenodema, Polymerus, Orthops, Lygus, Phytocoris, Adelphocoris, Grypocoris and Brachycoleus, the ACM (Adelphocoris, Creontiades, Megacoelum) complex, Closterotomus, Calocoris and Lygus complexes. The phylogenetic relationships and supporting morphological characters are discussed. The taxonomic status of Pseudomegacoelum irbilanum was evaluated. Scanning electron micrographs, drawings of genitalic structures, digital images of the habitus of selected species are presented to illustrate characteristic features. This study is the first attempt to analyze the phylogenetic relationship of plant bugs in Iran.
