Inferred tree using concatenated mitochondrial and nuclear genes. Most parsimonious tree obtained from heuristic search using the concatenated CoI, CoII, cac and sc datasets. The numbers at the nodes indicate bootstrap values from maximum parsimony (10⁴ replicates), maximum likelihood (10³ replicates), and Bayesian posterior probability percentages (2 × 10⁶ generations) respectively. Supports for within-species clades were all high and not included. Species groups are indicated: melanica (mel), robusta (rob), virilis (vir), mesophragmatica (mes) and funebris (fun). Inset shows the inferred history of the centric fusion in the melanica and robusta species group based on this phylogeny.
