Genetic units according to mitochondrial, nuclear and combined data. Distribution of mitochondrial clades, nuclear demes, and FCA groups. Mitochondrial clade G, deme G and FCA group G in magenta; mitochondrial clade N, deme N and FCA group N in yellow; mitochondrial clade P, deme P and FCA group P in light blue; mitochondrial clade C, deme C1 and FCA group C in orange; mitochondrial sub–clade c1 and deme C2 in pale orange; mitochondrial clade S, deme S and FCA group S in dark blue. Localities with more than one mitochondrial clade or more that one nuclear deme are coded with two colors. For the FCA map, squares, triangles and the two–coloured circle represent, respectively, localities where groups C and N co–occur, localities with individuals at the intersection between these two groups, and the locality where both conditions were observed.
