Grasshoppers and crickets (Insecta: Orthoptera) from the lower cretaceous of southern England

This is a synoptic monograph of fossil Orthoptera from the English Lower Cretaceous (Purbeck and Wealden groups). The previously described taxa of these insects are revised on the basis of type specimens and examination of extensive new material. Eight new genera and 30 new species are proposed: Probaisselcana cretacea sp. nov., Minelcana membranacea gen. et sp. nov., Panorpidium proximum sp. nov., P. bimacillatum sp. nov., ?P. parvum sp. nov. (Elcanidae); ?Cyrtophyllites cretaceus sp. nov. (Haglidae); Aenigmodus minutus gen. et sp. nov., Pseudaboilus wealdensis gen. et sp. nov., P. purbeckensis sp. nov., Tettigoilus sonorus gen. et sp. nov., ?Agrionidium obscurum sp. nov. (Prophalangopsidae); Notocearagryllus britannicus sp. nov., N. grandispeculum sp. nov., N. cordispeculum sp. nov., Anglogryllus lyristes gen. et sp. nov., A. rotundispeculum sp. nov.. Speculogryllus acutispeculum gen. et sp. nov., Sharategia davisi sp. nov., S. batchelorae sp. nov., S. baldocki sp. nov. (Baissogryllidae); ?Araripegryllus orientalis sp. nov. (Gryllidae); Deinovitimia occidentalis sp. nov. (Ensifera: infraorder incertae sedis); Cretoxya rasnitsyni gen. et sp. nov. (Tridactylidae); Locustopsis posterior sp. nov., Zeunerella prior sp. nov., Zessinia borealis sp. nov., Mesolocustopsis anglica sp. nov., M. angusta sp. nov., M. problematica sp. nov., and Britannacrida distincta gen. et sp. nov (Locustopsidae). The subfamily Baisselcaninae is synonymized with Elcaninae, and a new subfamily (Archelcaninae subfam. nov.) is proposed for a segregate of Elcaninae. A preliminary comparison of the Purbeck/Wealden with other Early Cretaceous orthopteran faunas is given. (c) 2006 Published by Elsevier Ltd.
