Distinguishing features
Sason robustum is characterized by absence of teeth on the claws; cuspules present on maxillae and labium; rastellum absent; the apex of the first tibia with a single stout prolateral spine; and the palpal bulb spherical with a tapering embolus.[3]
Taxonomy
Sason robustum was first described by Octavius Pickard-Cambridge in 1883.[1] He placed it in a new genus Sarpedon. However this name had already been used for a beetle, so in 1887, Eugène Simon put forward the replacement genus name, Sason.[4]
