FIGURE 1. A. Phylogenetic relationships derived from 18 in Systematic ambiguity in the well-established model system insect Scathophaga stercoraria (Diptera: Scathophagidae): sister species S. soror revealed by molecular evidence
FIGURE 1. A. Phylogenetic relationships derived from 18'002 Bayesian trees based on combined COI, 12S rDNA, 16S rDNA, and ITS2 sequences as established between 21 Scathophagidae species. The tree is a 50% majority rule consensus tree; values of posterior probabilities over 50% are indicated above branches (branches with probabilities less than 50% are collapsed). Scathophaga soror is evidenced in bold. B. Excerpt from a gene tree (Neighbour Joining, Kimura 2 parameters, COI gene) illustrating the sister group relationship between the monophyletic S. stercoraria and S. soror clades. Bootstrap values (for 1000 pseudo-replicates) are indicated above branches.

Figure 3. Maximum likelihood phylogenetic analysis of the dataset containing all the 16S Aglaopheniidae sequences used in this study. Note that the part of the phylogenetic tree with all the branches of the Aglaophenia pluma complex is represented in a separate figure – Figure 5. Numbers near the nodes indicate the values of bootstrap (left) and posterior probabilities (right) in percentages. Values less than 70% are replaced by <; if equal to 100%, an asterisk is used instead. Values of bootstrap and posterior probabilities are omitted if both were less than 70% for the same node. The branch length indicator represents 0.1 substitutions per site.

Data from: Combined molecular phylogenetic analysis of the Orthoptera (Arthropoda, Insecta) and implications for their higher systematics
A phylogenetic analysis of mitochondrial and nuclear rDNA sequences from species of all the superfamilies of the insect order Orthoptera (grasshoppers, crickets and relatives) confirmed that although mitochondrial sequences provided good resolution of the youngest superfamilies, nuclear rDNA sequences were necessary to separate the basal groups. To try to reconcile these data sets into a single fully resolved orthopteran phylogeny, we adopted consensus and combined data strategies. The consensus analysis produced a partially resolved tree, lacking several well-supported features of the individual analyses. However, this lack of resolution was explained by an examination of resampled data sets that identified the likely source of error as the relatively short length of the individual mitochondrial data partitions. In a subsequent comparison in which the mitochondrial sequences were initially combined, we observed less conflict. We then used two approaches to examine the validity of combining all of the data in a single analysis; comparative analysis of trees recovered from resampled data sets and the application of a randomization test. The results did not point to significant levels of heterogeneity in phylogenetic signal between the mitochondrial and nuclear data sets, and we therefore proceeded with a combined analysis. Reconstructing phylogenies under the minimum evolution and maximum likelihood optimality criteria, we examined monophyly of the major orthopteran groups using nonparametric and parametric bootstrap analysis and Kishino-Hasegawa tests. Our analysis suggests that phylogeny reconstruction under the ML criteria is the most discriminating approach for the combined sequences. The results indicate that the caeliferan Pneumoroidea and Pamphagoidea (as previously suggested) are polyphyletic. The Acridoidea is redefined to include all pamphagoid families other than the Pyrgomorphidae, which we propose should be accorded superfamily status.
