The Ischyropsalididae are a family of harvestmen with about 40 described species.
Species in this family range in body length from about four to 8.5 mm. They have moderately long legs. The greatly enlarged chelicerae can be almost twice as long as the body. While they share this feature with the Nipponopsalididae, this is a case of convergent evolution. The elongated pedipalps are rather slender. Some species occur in caves.
Members of this family are restricted to Europe, with many species found in the mountains (Pyrenees, Alps, Carpathian Mountains, and Dinaric Mountains. They reach into the Netherlands, northwestern Germany and Poland in the north and to Calabria in the south. A find from Sardinia is considered doubtful.
The nearest relatives of the Ischyropsalididae are possibly the genera Ceratolasma and Acuclavella (Ceratolasmatidae) from western North America. While the genus Taracus (Sabaconidae) has anatomical similarities, it is not closely related.
The genus name is a combination of Ancient Greek ischyros "strong" and psalis "shears", referring to the greatly enlarged chelicerae.
