Ischyropsalis is a genus of harvestmen in the monotypic family Ischyropsalididae, with 24 described species.[1][2]. They are found in Europe.[1][3][4][5]
Description
The genus Ischyropsalis was described by C.L. Koch, 1839, with the type species Ischyropsalis kollari C.L. Koch, 1839. Species in this genus range in body length from about 4 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.[6]
Distribution
Members of this genus 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 Southern Italy (i.e. Calabria) in the south. A find from Sardinia is considered doubtful.[6]

Etymology
The genus is feminine. The genus name is a combination of Ancient Greek ischyros "strong" and psalis "shears", referring to the greatly enlarged chelicerae.

According to L. Labrada and C. Prieto in Schönhofer (2013),[5] "Establishment of the present-day taxonomy and validating species-specific characters in Ischyropsalis have been mainly facilitated by the thorough revision of Martens (1969). Having been unable to borrow many types from the Iberian Peninsula, part of his work remained hypothetical for that local fauna, which was later corrected by Dresco (e.g. 1970, 1972), Luque (1991, 1992) and Prieto (1990a, 1990b). Of the 42 species described or emended by Roewer (1914, 1916, 1923, 1950, 1953a) only two remain valid."
