Abstract
ABSTRACTThe genusOrthobittacuswas established by Willmann (1989) and is characterised by a long Sc vein and the unusually developed medial sector for the Bittacidae. Four Jurassic species have been described in this genus to date:O. abshiricus(Martynova, 1951) from Kirgizia;O.desacuminatus(Bode, 1953) from Braunschweig (Germany);O. polymitusNovokshonov, 1996 from Karatau (Kazakhstan); andO. maculosusLiu, Shih, Bashkuev & Ren, 2016 from the Jiulongshan Formation of Daohugou (China). The fifth congeneric and second species from China,O. sunisp. nov., is described herein. The importance of the genusOrthobittacusfor the phylogeny of Bittacidae, as the most plesiomorphic genus, is discussed.
