Phylogeography. Geographic distribution of the short -291 bp- cytochrome b fragment. Symbol size accounts for the number of specimens: n = 1 for small symbols, n ≥ 2 otherwise (see Tables 4–5 for exact values). 1a) crested lark: G. randonii = square (see [42] for details on its Moroccan distribution); G. malabarica = triangle; G. cristata = circles (cristata = red; senegallensis = salmon; somaliensis = orange). Whenever possible, specimens in different localities within a single country are represented separately (Chad, Algeria, Russia). 1b) Thekla lark: G. theklae = circle (theklae = blue; superflua = purple; in Tunisia, the westernmost specimen with a theklae haplotype is shown separately); ellioti = triangle; praetermissa = white square; hueii = grey square (the Rift valley separating praetermissa and hueii in Ethiopia is indicated). We also show the geographic position of the sandy subspecies used to test the hypothesis of convergent evolution of plumage patterns (helenae and isabellina for the crested lark; carolinae and deichleri for the Thekla lark).
