Abstract

One new genus and new species, Sinaxymyia rara gen. et sp. nov., is described. Juraxymyia gen. nov. is proposed for Psocites fossilis Zhang, 2004. The genus and species, Psocites pectinatus (Hong, 1983), is redescribed based on new axymyiids from the Jurassic of China. The systematic positions for Crenoptychoptera decorosa Hao, Dong et Ren, 2009, Crenoptychoptera vulgaris Hao, Dong et Ren, 2009, and Crenoptychoptera vicina Hao, Dong et Ren, 2009 are reassessed, these do belong rather to Axymyiidae than to Eoptychopterinae, Ptychopteridae. All the impressions of male axymyiid flies are the first description in the geological records of Axymyiidae. Establishing homologies between the sclerites of the male genitalia of the Jurassic species described here and recent species of the family is difficult.
