 The discovery of more remains later, among which an almost complete skull, GIN 100/31, was reason for Bakhurina to name "D. parvus" in 1986 as a separate genus, and the species name became "Phobetor parvus".However, the genus name "Phobetor" was already being used as a junior synonym of a species of sculpin, namely, the arctic staghorn sculpin, "Gymnocanthus tricuspis" (synonym ""Phobetor tricuspis"" Krøyer, 1844) and thus unavailable.In 2009, Lü and colleagues re-examined much of the known dsungaripterid fossil material, and found that "Phobetor" was indistinguishable from "Noripterus", causing them to refer to it as a junior synonym.
