'''Desmatosuchinae''' is a major [[subfamily]] of [[aetosaur]]s within the [[clade]] [[Desmatosuchia]].<ref name=":0">{{Cite journal|last=Parker|first=William G.|date=2016-01-21|title=Revised phylogenetic analysis of the Aetosauria (Archosauria: Pseudosuchia); assessing the effects of incongruent morphological character sets|journal=PeerJ|language=en|volume=4|article-number=e1583|doi=10.7717/peerj.1583|issn=2167-8359|pmc=4727975|pmid=26819845|doi-access=free}}</ref> It is a [[stem-based taxon]] defined as all aetosaurs more closely related to ''[[Desmatosuchus]]'' than to ''[[Stagonolepis]],''<ref name="HL00">{{cite journal|last=Heckert|first=A.

The clade Desmatosuchinae has often been restricted to a few closely related aetosaurs with spiny armor, such as ''Desmatosuchus'', ''[[Longosuchus]]'', and ''[[Lucasuchus]]''.<ref name="PWG07" /> It was later expanded to include a number of ''[[Stagonolepis]]''-like aetosaurs with less specialized armor. Under this more expansive usage, the strongly-supported clade encompassing "traditional" desmatosuchines (''sensu stricto'') was given a new name, '''Desmatosuchini'''.<ref name=":0" /> [[Synapomorphies]] that diagnose this clade can be found in the [[osteoderm]]s. These include tongue-and-groove articulations for lateral plates present in dorsal presacral paramedian plates and large spikes on the lateral cervical, dorsal, and caudal plates.<ref name="PWG07">{{cite journal|last=Parker|first=W.
