The beetle-like Palaeozoic and Mesozoic roachoids of the so-called "umenocoleoid" lineage (Dictyoptera: Ponopterixidae fam. nov.)
Abstrakt
The position of Palaeozoic and Mesozoic roachoids and their relationships to crown-group Dictyoptera is an unresolved problem of insect systematics since Hennig's time. This contribution presents new data based on the wing venation of the Early Cretaceous group Cratovitismioidea (so-called "Umenocoleoidea") supplemented with the discovery of the first Late Palaeozoic representative.
As Umenocoleus, type genus of the Umenocoleidae, is considered as a Coleopterida, the roachoids currently included in the Umenocoleidae are transferred to the new family Ponopterixidae, in the new superfamily Cratovitismioidea. Permoponopterix lodevensis, a new ponopterixid genus and species, is described as the oldest representative of this superfamily, from the Middle Permian of the South of France.
A new species Ponopterix burkhardi is described from the Lower Cretaceous of Crato Formation in Brazil. Convergent adaptations of tegmina in Coleopterida, Protelytroptera and Cratovitismioidea are discussed. (C) 2014 Academie des sciences.
