The Archostemata are the smallest
Micromalthus debilis. Modern archostematan beetles are considered rare, but were more diverse during the Mesozoic
.
The term "Archostemata" is used more broadly by some authors to include both modern archostematans as well as
monophyletic group. Some genetic studies have recovered archostematans as the sister group of Myxophaga.[3]
