'''''Dictyopyge''''' is an extinct genus of prehistoric freshwater ray-finned fish that inhabited eastern North America during the early part of the Late Triassic.<ref name="sepkoskidb">{{cite journal|last=Sepkoski |first=Jack |title=A compendium of fossil marine animal genera |journal=Bulletins of American Paleontology |volume=364 |page=560 |year=2002 |url=http://strata.ummp.lsa.umich.edu/jack/showgenera.php?taxon=611&rank=class |access-date=2009-02-27 |url-status=dead |archive-url=https://web.archive.org/web/20110723131237/http://strata.ummp.lsa.umich.edu/jack/showgenera.php?taxon=611&rank=class |archive-date=2011-07-23 }}</ref> Two species are recognized, both from the early Carnian-aged Doswell Formation in what is now Virginia, United States:<ref name="Olsen1982">{{cite journal |last1=Olsen |first1=Paul E. |last2=McCune |first2=Amy R. |author-link2=Amy McCune |last3=Thomson |first3=Keith S. |year=1982 |title=Correlation of the Early Mesozoic Newark Supergroup by vertebrates, principally fishes |journal=American Journal of Science |volume=282 |issue=1 |pages=1–44 |bibcode=1982AmJS..282....1O |doi=10.2475/ajs.282.1.1 |doi-access=free}}.</ref><ref name=":2">{{Cite journal |last1=Weems |first1=Robert E. |last2=Tanner |first2=Lawrence H. |last3=Lucas |first3=Spencer G. |date=2016 |title=Synthesis and revision of the lithostratigraphic groups and formations in the Upper Permian?–Lower Jurassic Newark Supergroup of eastern North America |url=https://www.researchgate.net/publication/309853816 |journal=Stratigraphy |language=en |volume=13 |issue=2 |pages=111–153 |doi=10.29041/strat.13.2.03}}</ref>

Both species inhabited the rift lakes of the Newark Supergroup, which formed due to the tectonic changes that were starting to break up Pangaea.<ref name="Olsen1982" />

Several possibly unrelated species from the Triassic of Europe are provisionally referred to ''Dictyopyge'' ("''D.''" ''rhenana'', "''D.''" ''socialis'', "''D.''" ''catoptera'', "''D.''" ''superstes''), while three species from the Middle Triassic of Australia previously referred to ''Dictyopyge'' have been tentatively reallocated to the genus ''Brookvalia''.<ref name="Romano et al 2016">{{cite journal |last1=Romano |first1=Carlo |last2=Koot |first2=Martha B. |last3=Kogan |first3=Ilja |last4=Brayard |first4=Arnaud |last5=Minikh |first5=Alla V. |last6=Brinkmann |first6=Winand |last7=Bucher |first7=Hugo |last8=Kriwet |first8=Jürgen |title=Permian-Triassic Osteichthyes (bony fishes): diversity dynamics and body size evolution |journal=Biological Reviews |date=2016 |volume=91 |issue=1 |pages=106–147 |doi=10.1111/brv.12161 |pmid=25431138 |s2cid=5332637 }}</ref>
