Sabaconidae is a family of harvestmen with 59 described species in one genus, Sabacon, which is found throughout the Northern Hemisphere.
Name
The name of the type genus is derived from "Sabacon", an Egyptian king.
Description
This family is very easily recognizable on the basis of the unique pedipalp morphology, which is densely covered in plumose setae, and features a concave depression on the tibia, and a bulbous tarsus, which fits snugly into the tibial depression.
Distribution
Sabaconidae exhibits a wide, yet highly disjunct, distribution. Species can be found throughout North America, Europe, and Asia, though individual species usually have very restricted distributions.
Fossil Record
There is one species, Sabacon claviger (Menge, 1854) (and its synonym Sabacon bachofeni Roewer, 1939), known from Baltic amber.
Relationships
Sabaconidae belongs to the superfamily Ischyropsalidoidea. The family originally consisted of just the genus Sabacon, though Taracus was later added to the family. Hesperonemastoma was later moved to this family, as well, after molecular studies confirmed that this genus was closely related to Taracus. However, a new family, Taracidae, was later erected for Hesperonemastoma and Taracus, leaving Sabaconidae once again as having just a single genus (i.e. monogeneric). Currently, Sabaconidae is thought to be more closely related to Taracidae than Ischyropsalididae. The internal relationships of Sabaconidae are poorly understood.
