The Parvicursorinae are a group of theropod dinosaurs belonging to the Alvarezsauroidea.
In 1998, John R. Hutchinson and Luis Chiappe used the term Parvicursorinae for the first time in a discussion of the family tree of the Alvarezsauridae. Two years earlier, A.A. Karhu and A.S. Rautian nominated a family Parvicursoridae. Hutchinson and Chiappe believed that this group was part of the Alvarezsauridae. They wanted to use the new term Mononykinae. However, because of this group of Parvicursor, such a subfamily should be called Parvicursorina according to the rules of the ICZN. Hutchinson and Chiappe discussed this point but rejected this new name because they explicitly wanted to include Mononykus, what Karhu and Rautian did not do. In the literature, the term Mononykinae was then used until it became clear that Hutchinson and Chiappe's argument is irrelevant within the ICZN regulations. Paleontologists who value the strict rules began to apply the term Parvicursorinae.
In 2010, Jonah Choniere, for the first time, explicitly defined a definition of parvicursorina: the group consisting of the last common ancestor of Mononykus and Parvicursor and all descendants. Literature
