Liberiblattinidae


Liberiblattinidae is an extinct family of cockroaches known from the Jurassic to Cretaceous. Some taxa, like Cryptoblatta and Hydrokhoohydra, are suggested to be semiaquatic. Spongistoma is suggested to be a nectarivore due to its unique sucking/sponging "proboscis" mouthparts. Some authors have suggested that the family is ancestral to Mantodea.
