Yixiangomphus nom. nov., a new name for Archaeogomphus Lin, 1976 from the Upper Jurassic/Lower Cretaceous of Liaoning, China (Anisoptera: Gomphidae)

The new name is proposed for Archaeogomphus Q.-b. LIN (1976, Acta palaeontol. sin. 15: 99-100, 116, textfig. I, pi. 2, figs 5-6; — type sp.: A. labius), which is preoccupied by the extant gomphid genus Archaeogomphus E.B. WILLIAMSON (1919, Occ. Pap. Mus. Zool. Univ. Mich. 63: 1-6). In 1976, the author described a new genus and species of fossil Odonata from the Upper Jurassic-Lower Cretaceous deposits of western Liaoning Province, China under the name Archaeogomphus labius. The dragonfly, of which only the larval stage is known, is utterly distinct from all the known gomphid larvae, therefore a new genus was erected for its reception.
