Phylogenetic reconstruction of ionotropic receptors (including splicing isoforms) in the genome of P. japonica, as well as T. castaneum, L. decemlineata, D. ponderosae, A. planipennis. The two annotated clades (antennal and divergent) are color coded. Putative orthologs in P. japonica are highlighted in red. Fine scale subfamily level annotation of groups is provided in the outer most circle. The different density of subfamilies level annotation reflects the current limited knowledge of gene divergent IR subfamilies. The tree is rooted on the conserved IR8a and IR25a clades. Supported nodes (SH-aLRT >  = 70, UFB >  = 85) are shown with a dark gray dot along the branch
