Abstract: The Campanian assemblage of arthropods from the Cerro del Pueblo Formation in northeastern Mexico display some primitive characteristics. It consists of a small spider, a dragonfly assigned to the Libelluloidea, and cockroach Xonpepetla rinconensis Cifuentes-Ruiz et Vrsansky gen. et sp. nov. The last represents the latest record of the family Blattulidae and appears to be derived from the Aptian or Albian Cretaceous cockroaches of the genus Elisama Giebel, 1856 from the Crato Formation, Brazil.
