Bustylus is an extinct genus of eutherians in the family Adapisoriculidae. It was described by Emmanuel Gheerbrandt and Russell in 1991, and the type species is B. cernaysi, described from the late Paleocene of Cernay, France (from which the species epithet was derived), and possibly also from Germany.{{cite journal |author=Eric De Bast |author2=Bernard Sigé |author3=Thierry Smith |name-list-style=amp |year=2012 |title=Diversity of the adapisoriculid mammals from the early Palaeocene of Hainin, Belgium |url=http://app.pan.pl/article/item/app20100115.html |journal=Acta Palaeontologica Polonica |volume= 57 |issue=1| pages= 35–52|doi=10.4202/app.2010.0115 |doi-access=free }} Gheerbrandt later redescribed the species Peradectes marandati (Crochet and Sigé, 1983) as a species of Bustylus.Bustylus (Eutheria, Adapisoriculidae) and the absence of ascertained marsupials in the Palaeocene of Europe by Emmanuel Gheerbrant, 1991. {{doi|10.1111/j.1365-3121.1991.tb00200.x}} A third species, B. folieae, was described from the early Paleocene of Belgium by Eric De Bast, Bernard Sigé and Thierry Smith in 2012. B. folieae was named in honour of Dr. Annelise Folie.
