Wing geometry of Anopheles darlingi Root (Diptera: Culicidae) in five major Brazilian ecoregions

► We analyzed wing shape of Anopheles darlingi populations from five Brazilian ecoregions. ► Wing geometry is useful to diagnose macro-scale population structure in An. darlingi. ► Ecoregions may represent limiting barriers to dispersal of An. darlingi. ► Ecoregions may represent barriers that influence the population structuring.
