Micromalthidae is an ancient family of small beetles belonging to the suborder Archostemata. The only known living representative is the telephone-pole beetle, Micromalthus debilis. A few extinct species have been described,^[3] the oldest being the Late Permian Archaeomalthus synoriacos.^[1] It is one of the oldest families of beetles still existing today.^[3]

Micromalthus debilis is remarkable for its paedogenetic reproductive strategy which is almost unique in the animal kingdom, with the partial exception of Loricifera,^[4] and that could have already evolved in prehistoric Micromalthidae.^[2]^[1]
