Synsphyronus gracilis dorsal view

Synsphyronus gracilis

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.

Morphology

This small pseudoscorpion (ca. 3.5-4.5 mm in length) differs from other species of the genus by the combined presence of separate metatarsi and tarsi, an unconstricted anterior eye, a trichobothrial pattern of 8 on the fixed finger and 3 on the movable finger, and long, slender pedipalps.

Evolution

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.
