Figure 1 - Geographic records published of the species of Ptychadena from Mauritania identified at species level. Yellow dot from Senegal represent the previous northernmost record in West Africa of P. schillukorum. Green dot represent the localities were P. bibroni has been recorded in Mauritania. Localities with presence of P. trinodis are represented by red dots. The record of P. cf. mascareniensis is the blue coloured dot. The new record of P. schillukorum from Mauritania is shown as a yellow triangle (map created from http://www.simplemappr.net/).
