Combined and simplified cladogramm of holometabolan insect relationships, with selected autapomorphies for the clades addressed in this study. The topology is taken from the ML tree inferred from dataset 1 (i.e., the complete datamatrix). (1) Bootstrap support (BS) (bottom, black) is derived from 72 bootstrap replicates (MRE-based bootstopping criterion) of dataset 1. (2) BS values for the specific phylogenetic relationship (bottom, red) are derived from ML tree inferences from the seven specific decisive datasets 1 to 7. (3) relative support [%] values for the specific phylogenetic relationship (top) are derived from the Four-cluster Likelihood Mapping (FcLM) with the seven specific decisive datasets. Apomorphies are selected from the full lists of reconstructed groundplan characters (see Additional file 4, Chapter 5).
