Figure 2

Known geographical distribution of A. cajennense and collection sites. (A) Shaded green areas represent the approximate known range of A. cajennense (modified from [1, 40]). Colored circles indicate collection sites. Different colors correspond to the subdivision of the samples into phylogenetic clades as defined by the legend within the figure: NW = north-western clade (Texas, Mexico, Costa Rica, Ecuador), CO = Colombia; NE = north-eastern clade (French Guiana, Brazil-Rondonia); PE = Perú (Inter-Andean valley); EA = eastern clade (Brazil - Atlantic Forest - Mato Grosso and Argentina - Yungas); AR = Argentine clade (Argentine and Paraguayan Chaco). (B) Geographical area representing SDTF refugia (in black), savannas (in clear grey) and Chaco in dark grey (modified from [29]).
