Grammomys dryas ( Thomas, 1907 )

Figure 3. Maximum likelihood phylogenetic tree (IQ-TREE) inferred from the concatenated dataset of 3066 loci (92 687 single nucleotide polymorphisms) genotyped by the ddRAD approach. Black dots show node support with ultrafast bootstrap (1000 replicates)> 95, lower support at two nodes is shown by numbers. Four major groups of Grammomys (sensu Bryja et al. 2017, i.e. based mostly on mtDNA) are shown by different colours. Bars on the right side show delimitations by mtDNA lineages (see Fig. 2), MOTUs from the branch-cutting of the ML tree and from the INFOMAP clustering based on the co-ancestry matrix, and the proposed taxonomy (for more details, see the ‘Taxonomic revision of Grammomys’ section).

Figure 7. Taxonomic summary of the macmillani group. A and C, the distribution of mtDNA lineages.The different colours correspond to different lineages (m1–m8 described by Bryja et al. 2017; m9–m11 discovered in this study). B and D, delimitation of MOTUs based on ddRAD data. The Roman numerals III–VII in coloured rectangles show MOTUs delimited by INFOMAP clustering, with symbols in the same colours indicating localities of ddRAD-genotyped specimens.The Arabic numerals 4–6 show the MOTUs identified by branch-cutting of the ML tree.The proposed taxonomy is shown below the maps; MOTUs IV–VI from INFOMAP were grouped together by branch-cutting as MOTU 5 (see Fig. 3), but we propose to split them into two ecologically different species, Grammomys ibeanus (IV and V) and Grammomys macmillani (VI); see main text for more details. Stars show type localities for the macmillani group.The proposed species names are shown by larger bold letters next to their type localities, while smaller letters correspond to synonyms.
