Ant. III with 4–5 strong setae much longer, stronger and stouter than the rest. Mucronal bristle present or absent. Tenent hairs present or absent. If present not overhanging claw but standing out at an angle from tibio-tarsus. Claw with or without a tunica. Dorsal gland openings of furcal segment absent.

Represented in New Zealand by the European S. viridis, which probably has been introduced into this country, and the Australian species S. denisi.
