A new genus of the family Locustopsidae (lnsecta, Caelifera) in the Santana Formation (Lower Cretaceous, Northeast Brazil)

Resumen

The new genus Crarozeunerella (Caelifera, Locustopsidae) and three constituent new species, C. neotropica n. sp., C. nordestina n. sp., and C. amedegnatoi n. sp., are described from the Santana Formation (Lower Cretaceous) of northeastern Brazil. The family Locustopsidae was hitherto represented in the Brazilian Cretaceous by two other genera: Zessinia Martins-Neto and Locustopsis Handlirsch, suggesting that the group was most successful in the Southern Hemisphere during Cretaceous times. This family is typical of the Mesozoic and the oldest record is from the Lower Triassic of Australia. The family is represented now by nine genera including more than forty species. Thirty in the genus Locustopsis Handlirsch Handlirsch, which is known from Jurassic rocks in Europe and Asia as well as from Cretaceous rocks in Asia, Africa and Brazil.
