Multilocus phylogeny of the genus Acomys. a Bayesian phylogeny of the concatenated multi-locus matrix calculated in MrBayes. The support from Bayesian analysis in MrBayes (posterior probability, PP) and maximum likelihood analysis in RAxML (bootstrap probability, BP) is indicated by different colours on the nodes (black PP > 0.95, BP < 70; violet PP < 0.95, BP > 70; blue PP > 0.95, BP > 70). Five main Acomys groups (subspinosus, spinosissimus, russatus, wilsoni and cahirinus) are shown by different colours. The results of four different species delimitation approaches (“by-eye” prior; two delimitation approaches based on mtDNA: mPTP, ABGD; and a multilocus species delimitation in STACEY - see more details in the text) are shown in columns on the right, where individual “species” are separated by black lines. Additional information for 26 delimited taxa are provided, abbreviation of the lineages, and previously used taxonomic assignments. b DensiTree cloudogram of coalescent species trees from STACEY (for MCC species tree with PP see Additional file 4)
