'''''Aeorestes''''' is a subgenus of ''Lasiurus'' commonly known as the '''hoary bats'''.

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 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%.<ref name="Baird 2017"/>

''Aeorestes'' split from ''Lasiurus'' approximately 17.99 Ma (million years ago). ''A. villosissimus'' diverged from the hoary bat and the Hawaiian hoary bat approximately 4.61 Ma, while the latter two species split from each other 1.35 Ma.<ref name="Baird 2017"/>

==Species== Based on Baird et al., ''Aeorestes'' contains the following members:<ref name="Baird 2015"/> *Hoary bat (''Lasiurus cinereus'') *Big red bat (''Lasiurus egregius'') *Hawaiian hoary bat (''Lasiurus semotus'') *South American hoary bat (''Lasiurus villosissimus'')
