Inferred trees derived from mitochondrial and nuclear genes. Majority rule consensus trees obtained by maximum parsimony using a) mitochondrial (combined CoI and CoII) and b) nuclear (combined cac and sc) data partitions. Numbers at the nodes indicate bootstrap values from maximum parsimony (10⁴ replicates). Scale bars indicate a branch length corresponding to 50 substitutions. Clades representing the robusta (rob) and melanica (mel) species groups are labeled.
