Erebia ( Erebia) demmia B. Warren, 1936 , stat. nov. is a species distinct from Erebia ( Erebia) pawloskii Ménétriés, 1859

Originally proposed as a subspecies of Erebia ( Erebia) theano (Tauscher, 1806) ( type locality in Altai Mts.), and currently treated as a subspecies of Erebia ( Erebia) pawloskii Ménétriés, 1859 ( type locality in Russia: Sakha), Erebia theano demmia Warren, 1936 ( type locality in USA: Colorado, San Juan Mountains) is genetically differentiated from them at the species level ( Fig. 3a red), e.g., Fst / Gmin statistics for the phylogenetically closest pair ( E. theano demmia and E. pawloskii ) are 0.34/0.015. Therefore, we propose that Erebia ( Erebia) demmia B. Warren, 1936 , stat. nov. is a species distinct from Erebia ( Erebia) pawloskii Ménétriés, 1859 .

Fig. 3. Phylogenetic trees of selected Erebia (Erebia) species constructed from protein-coding regions in: a) the nuclear genome (autosomes), based on 415,959 positions, and b) the mitochondrial genome. Different species and subspecies are colored differently: E. theano (brown), E. stubbendorfii (olive), E. pawloskii sajana stat. rest. (purple), E. pawloskii pawloskii (blue), E. pawloskii bilibinia (magenta), E. pawloskii alaskensis (green), E. pawloskii canadensis (dark blue), E. pawloskii ethela W. H. Edwards, 1891 (cyan), and E. demmia stat. nov. (red). Ultrafast bootstrap (Minh et al. 2013) values are shown at nodes. Gaps in terminal branches indicate that a segment of a tree was cut out to reduce its horizontal dimension (to allow an increase in the font size), i.e., a branch with a gap is longer than shown.
