Abstract A new Saldidae (MCT 6959-I) from the Crato Formation (Lower Cretaceous, late Aptian), Santana Group, Araripe Basin (northeastern Brazil) is described and illustrated. Olindasalda gondwanica n. gen. n. sp. is the first fossil Saldidae recorded from the Gondwanan supercontinent. The new genus can be distinguished from other members of the subfamily Chiloxanthinae by its small (4.49 mm) and oval-elongated body, absence of spots on the corium of the hemelytron, long R vein, and much-reduced first cell of the membrane. Remarks on the geology of the type locality and a comparison of the new genus with other saldids are provided.
