Extinct genus of insects
"Monura" redirects here. For a synonym of a genus of rotifers, see
Colurella .
Dasyleptus is an extinct genus of wingless insects in the order
Archaeognatha , and the only member of the family Dasyleptidae . They resembled 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 was formerly placed in its own extinct order, Monura , but this is now treated as a suborder of Archaeognatha.
