<p>A new species of the genus <i>Armigatus</i> is described from the Cenomanian/early Turonian Akrabou Formation of Morocco. Similar to other ellimmichthyiforms, <i>Armigatus oligodentatus</i>, sp. nov., has parietals in contact with each other along the midline, has a beryciform foramen in the anterior ceratohyal, and lacks the recessus lateralis. The new species is placed in the genus <i>Armigatus</i> based on the incomplete predorsal series of heart-shaped scutes with rounded and smooth posterior border. However, this new species differs from the other known members of the genus in the lack of teeth on the parasphenoid and endopterygoid bones. This is the first report of a species of <i>Armigatus</i> from southeastern Morocco; previously, the genus was known only from the Late Cretaceous deposits of the eastern part of the Tethys. Therefore, <i>Armigatus oligodentatus</i> sp. nov. extends the distribution of the genus across the Tethys Sea and provides valuable information about the evolutionary history and paleoecology of the Ellimmichthyiformes.</p> <p>http://zoobank.org/urn:lsid:zoobank.org:pub:FD65FEA4-E219-4892-8AA4-6254E60EE5DB</p> <p>SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at <a href="http://www.tandfonline.com/UJVP" target="_blank">www.tandfonline.com/UJVP</a></p> <p>Citation for this article: Vernygora, O., and A.
