Cretamystilus (meaning "Cretaceous Mystilus") is an extinct genus of mirid insect in the tribe Mecistoscelini known from a fossil preserved in a piece of Cenomanian (Late Cretaceous) Burmese amber from the Hukawng Valley, Myanmar. Cretamystilus, which was the first extinct genus to be named in 2021, contains a single species, C. herczeki.{{Cite journal|last1=Kim |first1=J. |last2=Lim |first2=H. |last3=Jung |first3=S. |title=A first member of bamboo-feeding lineage plant bug (Hemiptera: Heteroptera: Miridae: Mecistoscelini) in mid-Cretaceous Burmese amber |year=2021 |journal=Cretaceous Research |volume=121 |pages=Article 104741 |doi=10.1016/j.cretres.2020.104741 |bibcode=2021CrRes.12104741K |s2cid=233567365 }} Cretamystilus is the first member of the Miridae in the fossil record known to date.
