Abstract
Examination of new fossil specimens of Prosyntexis from the Lower Cretaceous Crato Formation of Brazil reveled a new species namely Prosyntexis sennlaubi sp. nov. To ensure the validity of the new taxon we examined previously described and figured specimens but we also figured an additional specimen of Prosyntexis gouleti Sharkey, 1990. The new species can be differentiated from the other Prosyntexis species of the Crato formation by its larger size but also in having the cell 2R1 small, the cell 2M small and short, the cell 3R1 narrow and the vein a directed toward wing apex. We performed a Geometric Morphometric Analysis (GMA) to estimate the variation in the forewing venation of the two species from the Crato Formation and ensure our placement.
