Sketch of northern Madagascar depicting the eight Inter-River-Systems (IRS 0–VII) (A), and maximum-likelihood tree of Lepilemur spp. based on complete mitogenome sequences (B)

In A, questionable species designations are indicated as: A=species in Andriaholinirina et al. (2006); C=species in Craul et al. (2007); L=species in Louis et al. (2006); R=species in Rabarivola et al. (2006). Red dots=sample location for this study; gray dots=additional sample locations of previous studies that support respective mitochondrial lineages; IRS VI includes Nosy Bé. In B, node support <100% ML BS is given at respective nodes; PP for all nodes is 1.0. Species names are followed by GenBank accession numbers and geographic identifiers (see Lei et al., 2017). Respective IRSs are in blue. Type specimens of L. dorsalis and L. grandidieri are highlighted in bold. Designation of L. dorsalis is according to Louis et al. (2006).
