(also Telyphones, Holopeltidia), an order of relatively large flagellate arachnids measuring approximately 7 cm in length. The thorax and head are grown together, and the abdomen ends in a long segmented tail-like limbo. Uropygi, distributed mainly in the tropics, are nocturnal insectivorous predators.

Within arachnids only the spermatozoa of Scorpiones, Uropygi, Amblypygi, Araneae, Pseudoscorpiones and Ricinulei possess a flagellum (summary in Alberti 2000), in contrast to the spermatozoa of Solifugae, Acari, Palpigradi and Opiliones, which are aflagellate (the only exception is the opilionid genus Siro which shows an axoneme during the spermatogenesis; Juberthie et al.
