Resumo

Cratoaeschnidium martinsnetoi gen. et sp. nov., third genus and species of the family Aeschnidiidae from the Crato Formation (Brazil), is described and illustrated based on one well-preserved forewing. It can be differentiated from the other genera in the family, inter alia, because its discoidal triangle is very narrow with only one row of cells; three rows of cells between Mspl and MAa, and between Rspl and IR2; one row of cells between CuAa and MP in basal part; three rows of cells between RP3/4 and MAa. This new genus and species confirms that much can be expected in regard to discovering the Odonata in the Crato Formation. (AU)
