Abstract

Zheng, Y., Chen, J., Zhang, J. & Zhang, H., 2 August 2019. New fossil sawflies (Hymenoptera, Xyelidae) from the Middle Jurassic of northeastern China. Alcheringa XX, xxx-xxx. ISSN 0311-5518. Magnaxyela rara gen. et sp. nov. and Abrotoxyela curva sp. nov. (Xyelidae, Macroxyelinae, Gigantoxyelini) are described from the Middle Jurassic Jiulongshan Formation at Daohugou Village, Inner Mongolia, China. The two new species are confidently assigned to tribe Gigantoxyelini of subfamily Marcroxyelinae based on their wing venation and various other morphological characters. Magnaxyela rara is established based on the following forewing characters: pterostigma sclerotized completely, Sc two-branched and meeting R before origin of Rs, 1-Rs as long as 1-M, but shorter than Rs + M, R curved bewteen 1r-rs and 2r-rs and cell 2r longer than 1r. Abrotoxyela curva is differentiated from congeneric forms by the two-branched vein Sc of the forewing, Sc2 short and inclined towards the base of the wing, 1-Rs, 1-M and Rs + M nearly equal in length, crossvein 1m-cu longer than 1cu-a. The fossils described herein increase the diversity of the Mesozoic Xyelidae.
