Abstract
The first mygalomorph spiders from the Lower Cretaceous Crato Lagersta¨tte of Ceara` Province, north-east Brazil, are described, from adult males and females, in two new genera and species: Cretadiplura ceara Selden, gen. et sp. nov. and Dinodiplura ambulacra Selden, gen. et sp. nov. They belong to the extant family Dipluridae, hitherto known as fossils only from Tertiary strata; thus this occurrence extends
the family record by some 90 myr.
