Revision and new taxa of fossil prophalangopsidae (Orthoptera: Ensifera)

Abstract

Taxonomy is investigated and revised for some prophalangopsid insects, yielded by the Middle Jurassic Jiulongshan and Upper Jurassic-Lower Cretaceous Yixian formations in China. Flexaboilus retinervius Li, Ren & Meng, 2007 and Furcaboilus excelsus Li, Ren & Meng, 2007 are considered as synonyms of Allaboilus gigantus Ren & Meng, 2006. Protaboilus lini Ren & Meng, 2006 is considered a synonym of Aboilus stratosus Li, Ren & Wang, 2007. Hebeihagla Hong, 1982b, Habrohagla Ren, Lu, Guo & Ji, 1995, Grammohagla Meng & Ren, 2006, Trachohagla Meng, Ren & Li, 2006 are considered as synonyms of Parahagla Sharov, 1968; Athehagla Meng & Ren, 2006 is considered a synonym of Ashanga Zherichin 1985. Genera Allaboilus, Circulaboilus Li, Ren & Wang, 2007 and Ashangopsis Lin, Huang & Nel, 2008 are revised. In addition, one new genus Scalpellaboilus gen. nov. and four new species: Scalpellaboilus angustus sp. nov., Circulaboilus priscus sp. nov., Allaboilus robustus sp. nov. and A. hani sp. nov. are described. Some wing venation variability in Prophalangopsidae is briefly discussed.
