[2] This species was first described by three biologists from the University of Belgrade (Dalibor Z Stojanović, Mirko Ševićin, and Slobodan E Makarov) in 2024, based on specimens extracted from soil samples from Medvednik mountain in western Serbia.

This species is whitish with a pale yellowish color on parts of the head, antennae, mouthparts, forcipular segment, and claws of the walking legs.

[2] Diagnostic features of this species include not only its small size and modest number of legs but also a distinctive set of other traits.

These traits include minute denticles on the first article of the forcipule, a rudimentary claw on the ultimate legs, and the absence of ventral pore-fields on the sternites.

The species S. walachica has rudimentary claws on its ultimate legs but also features pore-fields on some sternites, has no denticles on the first article of the forcipule, and is twice as long as S. antici.
