Distribution of the endemic crocea-group of Platycypha species and all congeneric taxa. Names of taxa that favour open habitats are in black, those tending toward forest in white (although P. rufitibia occurs on very open rivers); abbreviations: am — P. amboniensis, in — P. inyangae, la — form “lacus” of P. caligata which may represent a distinct species, pi — P. pinheyi. The rather dispersed forest species P. lacustris is shown with black squares (adapted from Dijkstra 2008).
