New Middle Permian insects from Salagou Formation of the Lodeve Basin in southern France (Insecta: Pterygota)
Abstract
New insects are described from the Middle Permian (Guadalupian) of Salagou Formation in the Lodeve Basin (Languedoc region, France). Palaeopterans are represented by new odonatopterans viz.
Huangiopterum lodevensen. gen., n. sp. and Huangiopterum species B, attributed to clade Panodonata (Huangiopteridae n. fam.), already recorded through the family Saxonagrionidae in the same formation, and a diaphanopterodean Martynovia cf. halli Beckemeyer 2004 (Martynoviidae) known from the Lower Permian of Oklahoma. Archaeorthopterans are supplemented by Bethouxia ariegensisn. gen., n. sp., Paralongzhua elongatan. gen., n. sp., Lodevolongzhua incompletan. gen., n. sp., the caloneurodean Jarmiloptera mouralensisn. gen., n. sp., and a cnemidolestodean cf.
Tococladus sp. (Tococladidae). Permophyllum rotundatumn. sp. (?Tettigoniidae) demonstrates the first presence of Orthoptera with wings probably mimicking Peltaspermales reproductive organs in Late Palaeozoic possibly analogous to the known crypsis of roachoid tegmina with pteridosperm pinnules.
Frequent occurrence of hardly identifiable grylloblattid wing fragments support their significant role in term of abundance and diversity of the Permian faunas.
