The Archostemata are the smallest suborder of beetles, consisting 45 living species in five families.[1] They are an ancient lineage with a number of primitive characteristics. They are similar in morphology to the first beetles, which appear in the fossil record about 250 million years ago. Antennae may be thread-shaped (filiform) or like a string of beads (moniliform). This suborder also contains the only beetles where both sexes are paedogenic, Micromalthus debilis.

These beetles are considered rare.[citation needed] Fossil deposits from the Permian suggest that the Archostemata were once much more common and dispersed over a wide portion of the globe, and the species that remain are scattered vestiges of their former population.
