Abstract
ABSTRACT One new genus Evacuxyela gen. nov., with two new species, Evacuxyela conflata sp. nov. and Evacuxyela hsiaoae sp. nov., is described and illustrated on the basis of two fossils from the Middle Jurassic Jiulongshan Formation of northeastern China. The new genus Evacuxyela gen. nov. is placed in the subfamily Macroxyelinae Ashmead, 1898, tribe Angaridyellini of Xyelidae, mainly based on veins C and R connected by a bridge next to pterostigma. The two new fossil species are similar, but differentiated by degree of expansion for hind femur, sclerotisation of pterostigma and venational details. In addition, the well-preserved spurs and expanded femora of hind legs provide important morphological characters to enhance our understanding of Xyelidae.
