Apystomyia is a genus of flies in the family Apystomyiidae. The genus contains the single living Apystomyiidae species, Apystomyia elinguis, which is primarily found in California. Details of its life history are largely unknown. The extinct genus Hilarimorphites is known from the Cretaceous Burmese and New Jersey ambers.{{Cite journal|last1=Grimaldi|first1=David|last2=Arillo|first2=Antonio|last3=Cumming|first3=Jeffrey|last4=Hauser|first4=Martin|date=2011-11-21|title=Brachyceran Diptera (Insecta) in Cretaceous ambers, part IV: Significant New Orthorrhaphous Taxa|url=http://zookeys.pensoft.net/articles.php?id=2980|journal=ZooKeys|issue=148|pages=293–332|doi=10.3897/zookeys.148.1809|issn=1313-2970|pmc=3264415|pmid=22287902|doi-access=free|bibcode=2011ZooK..148..293G }} Formerly placed in the Asiloidea, molecular phylogenetic studies in 2010 placed the genus unambiguously as a sister of the Cyclorrhapha within the clade Eremoneura.{{cite journal|doi=10.1016/j.ympev.2010.04.017 |title=A multigene phylogeny of the fly superfamily Asiloidea (Insecta): Taxon sampling and additional genes reveal the sister-group to all higher flies (Cyclorrhapha) |year=2010 |last1=Trautwein |first1=Michelle D. |last2=Wiegmann |first2=Brian M. |last3=Yeates |first3=David K. |journal=Molecular Phylogenetics and Evolution |volume=56 |issue=3 |pages=918–930 |pmid=20399874 |bibcode=2010MolPE..56..918T }}{{cite journal|doi=10.1111/syen.12275|title=Taxon sampling to address an ancient rapid radiation: A supermatrix phylogeny of early brachyceran flies (Diptera)|year=2018|last1=Shin|first1=Seunggwan|last2=Bayless|first2=Keith M.|last3=Winterton|first3=Shaun L.|last4=Dikow|first4=Torsten|last5=Lessard|first5=Bryan D.|last6=Yeates|first6=David K.|last7=Wiegmann|first7=Brian M.|last8=Trautwein|first8=Michelle D.|journal=Systematic Entomology|volume=43|issue=2|pages=277–289|doi-access=free|bibcode=2018SysEn..43..277S }}
