Dasyleptus is an extinct genus of wingless insects in the order Archaeognatha, and the only member of the family Dasyleptidae. They resembled juveniles of their modern relatives and had a single lengthy filament projecting from the end of the abdomen. They also had a pair of leg-like cerci and some non-ambulatory abdominal appendages. The largest specimens reached 30 millimetres (1.2 in) or more, not counting the length of the filament.[2] Dasyleptus species are mostly known only from the Late Carboniferous and Permian, but one species recorded from the Middle Triassic indicates that they survived the Permian–Triassic extinction event.[3] Dasyleptus was formerly placed in its own extinct order, Monura, but is this is now treated as a suborder of Archaeognatha.[4][5]
