It contains two living groups, Mantophasmatidae (gladiators) native to southern Africa, and Grylloblattidae (ice crawlers) native to cold montane environments in the Northern Hemisphere. Both groups are wingless.

==History of research== The name was originally coined in 1915 as an order for Grylloblattidae and largely forgotten until it was resurrected and redefined ("Notoptera Crampton ''sensu novum''") by Engel and Grimaldi in 2004 (after the discovery of living Mantophasmatidae), who recommended to give a single order that includes both the living and fossil representatives of the lineage.<ref name="Engel Grimaldi 2004">{{cite journal | last1=Engel | first1=Michael S. | last2=Grimaldi| first2=David A. | title=A New Rock Crawler in Baltic Amber, with Comments on the Order(Mantophasmatodea: Mantophasmatidae) | journal=American Museum Novitates | publisher=American Museum of Natural History (BioOne sponsored) | issue=3431 | year=2004 | pages=1–12 | issn=0003-0082 | doi=10.1206/0003-0082(2004)431<0001:anrcib>2.0.co;2 | s2cid=85653533 | url=https://zenodo.org/record/5375006 }}</ref>

== Evolutionary history == [[File:Peng et al. 2025 f04.jpg|thumb|Life restoration of ''Zygogrylloblatta'', a winged "grylloblattidan" from the mid-Cretaceous|left]] The earliest stem-group representatives of Notoptera/Xenonomia had emerged by the Late Carboniferous, around 320 million years ago. Early members of the group, which unlike modern notopterans had wings, have been referred to as members of "Grylloblattida" and "Reculida", with their relationships to modern notopterans historically being the subject of controversy. Winged "grylloblattidans" reached their apex of diversity during the Permian (299-252 million years ago), where they represented up to a third of all insects at some localities.<ref name=":0" /> The earliest mantophasmatids are known from the Middle Jurassic of China, around 160 million years ago.<ref>{{Cite journal |last1=Huang |first1=Di-ying |last2=Nel |first2=André |last3=Zompro |first3=Oliver |last4=Waller |first4=Alain |date=2008-06-11 |title=Mantophasmatodea now in the Jurassic |url=https://www.researchgate.net/publication/5311278 |journal=Naturwissenschaften |volume=95 |issue=10 |pages=947–952 |doi=10.1007/s00114-008-0412-x |issn=0028-1042 |pmid=18545982 |s2cid=35408984}}</ref> No fossil record of modern grylloblattids is known, though the winged ''Aristovia'' and ''Zygogrylloblatta'' are known from the Burmese amber of Myanmar dating to the mid-Cretaceous around 100 million years ago, have mouthparts very similar to modern grylloblattids, indicating their closer relationship to modern grylloblattids than to mantophasmatids.<ref name=":0" /><ref name=":1">{{Cite journal |last=Peng |first=Ancheng |last2=Engel |first2=Michael S. |last3=Boderau |first3=Mathieu |last4=Legendre |first4=Frédéric |last5=Liu |first5=Yu |last6=Nyunt |first6=Thet Tin |last7=Wang |first7=Bo |last8=Nel |first8=André |date=June 2025 |title=Descending from trees: a Cretaceous winged ice-crawler illuminates the ecological shift and origin of Grylloblattidae |url=https://royalsocietypublishing.org/doi/10.1098/rspb.2025.0557 |journal=Proceedings of the Royal Society B: Biological Sciences |language=en |volume=292 |issue=2049 |doi=10.1098/rspb.2025.0557 |issn=1471-2954|pmc=12173512 }}</ref> Mantophasmatids and grylloblattids are thought to have lost their wings independently.
