Diplurans possess a characteristic pair of [[Cercus|cerci]] projecting backwards from the last of the 11 abdominal [[somite]]s.<ref name="Earthlife">{{cite web|url=http://www.earthlife.net/insects/diplura.html|title=Diplura|date=November 11, 2005|publisher=The Earthlife Web|url-status=dead|archive-url=https://web.archive.org/web/20061205033402/http://earthlife.net/insects/diplura.html|archive-date=2006-12-05}}</ref> These cerci may be long and filamentous or short and pincer-like,<ref name="Iziko">{{cite web|url=http://www.museums.org.za/bio/insects/diplura/|title=Diplura|year=2004|publisher=[[Iziko Museums of Cape Town]]|url-status=dead|archive-url=https://web.archive.org/web/20070926231819/http://www.museums.org.za/bio/insects/diplura/|archive-date=2007-09-26}}</ref> leading to occasional confusion with [[earwig]]s.<ref name="CSIRO">{{cite web |title=Diplura |url=http://www.ento.csiro.au/education/hexapods/diplura.html |publisher=[[Commonwealth Scientific and Industrial Research Organisation|CSIRO]] Entomology}}</ref> Some diplurans have the ability to shed their cerci if necessary ([[autotomy]]). Moulting occurs up to 30 times throughout the life of a dipluran, which is estimated to last up to one year.

As [[Entognatha|entognaths]], the mouthparts are concealed within a small pouch by the lateral margins of the head capsule. The mandibles usually have several apical teeth.<ref name=":1" /> Diplurans do not possess any eyes or wings.<ref name=":0" />

In males, glandular setae or disculi may be visible along the first abdominal sternite. External genital organs are present on the eighth abdominal segment.<ref name=":1" />
