Genomic Structures of E(Spl) complexes from Coleoptera. Schematic phylogeny of Coleoptera with structures of E(spl)-C from examined species. Colour coding of bHLH genes follows Fig. 1 (bHLH-1, light blue; bHLH2, Dark blue; her, green). Red hexagons indicate mα, genes. White ovals indicate inserted genes with no homology to bHLHO or mα. Arrows indicate direction of transcription
