Synsphyronus PSE091 dorsal view

Synsphyronus `PSE091 7/3 short`

Pseudoscorpions are small arachnids that resemble scorpions with their grasping pincers (pedipalps). However, they lack the distinctive stinging tail of scorpions, and instead have a pear-shaped body. The full species diversity of pseudoscorpions is unknown, and the Western Australian Museum is a major contributor to describing species and resolving relationships in this poorly understood group.


This small pseudoscorpion (ca. 2.5-3.0 mm in length) differs from other species of the genus by the combined presence of fused metatarsi and tarsi, a constricted anterior eye and a trichobothrial pattern of 7 on the fixed finger and 1 on the movable finger.


The genus Synsphyronus is the most diverse genus of Garypidae, with approximately 30 named species in Australia, and two named species in New Zealand. A new species has been found in New Caledonia, and there are numerous undescribed species in Australia.
