The subgenus was initially described by Austrian zoologist [Leopold Fitzinger](/source/Leopold_Fitzinger) in 1870.[{{cite journal|last=Fitzinger|first=L.| year=1870| journal=Sitzungsberichte der Kaiserlichen Akademie der Wissenschaften. Mathematisch-Naturwissenschaftliche Classe.

Familie der Fledermäuse (Vespertiliones). I. Abtheilung| volume=61|page=457|url=https://biodiversitylibrary.org/page/35520696}}]
Based on genetic divergence within ''[Lasiurus](/source/Lasiurus)'', Baird et al. recommended that the hoary bats be recognized as a separate genus. They additionally recommended that ''[Dasypterus](/source/Dasypterus)'' should be elevated from a [subgenus](/source/subgenus) to a genus as well.[{{cite journal|doi=10.1093/jmammal/gyv135|title=Molecular systematic revision of tree bats (Lasiurini): Doubling the native mammals of the Hawaiian Islands|journal=Journal of Mammalogy|volume=96|issue=6|pages=1255–1274|year=2015|last1=Baird|first1=Amy B.|last2=Braun|first2=Janet K.|last3=Mares|first3=Michael A.|last4=Morales|first4=Juan Carlos|last5=Patton|first5=John C.|last6=Tran|first6=Christina Q.|last7=Bickham|first7=John W.|doi-access=free}}] However, as ''Lasiurus'' was previously [monophyletic](/source/monophyly), some authors see the creation of two new genera—''Aeorestes'' and ''Dasypterus''—as a solution to something that was not a problem.[{{cite journal|last1=Ziegler| first1=A.

L. M| last2=Garbino| first2= G. S. T| last3= Cláudio| first3=V. C.| last4= Moratelli| first4= R.|journal=Zootaxa| volume=4379| issue=3}}] Teta advocated using ''Aeorestes'' as a subgenus and retaining the usage of ''Dasypterus'' as such.[{{cite journal|doi=10.1515/mammalia-2018-0059|title=The usage of subgenera in mammalian taxonomy|journal=Mammalia|year=2018|last1=Teta|first1=Pablo|volume=83|issue=3|pages=209–211|doi-access=free|hdl=11336/121063|hdl-access=free}}]
In a 2017 follow-up to their 2015 study, Baird et al. again expressed that ''Aeorestes'', ''Dasypterus'', and ''Lasiurus'' should be separate genera comprising the [tribe](/source/tribe_(biology)) Lasiurini. They stated that the genetic distance of the three genera was much greater than observed between other bat genera, on average. In contrast to the average of 12.0% inter-generic divergence reported from another study on bats, ''Aeorestes'' and ''Dasypterus'' varied 18.79%; ''Aeorestes'' and ''Lasiurus'' varied 19.05%; and ''Dasypterus'' and ''Lasiurus'' varied 19.79%.
