Paralycoptera wui is an extinct species ofbasalosteoglossoid from EarlyCretaceous freshwater environments of what is now China.P. wui was originally described as alycopterid osteoglossomorph close toLycoptera, though, later, on the basis of several well preserved specimens, Xu and Chang (2009) reassessed it as a basal osteoglossoid on the basis of better-preserved fossil material.[1] Xu and Chang also synonymized the second described species,P. changi, as well asTanolepis andYungkangichthys hsitanensis (while neglecting the Japanese species,Y. macrodon), alleging that all of them were too similar toP. wui to merit separate generic or specific status, and that any anatomical differences between these taxa were due totaphonomic distortions of the specimens. In the same study, Xu and Chang also synonymized the related Japanese osteoglossomorph genus,Aokiichthys, on the basis of the two genera having an almost identical number ofvertebrae, though they did not specify whether they were simply merging the two genera together, or if all the species withinAokiichthys were to be demoted assynonyms ofP. wui.
