Original Description

Druppulida with simple ellipsoidal cortical shell and double medullary shell, in the main axis with two large opposite polar spines of equal size and similar form.

Etymology:
From the Greek stylos = stiletto, and atractos = spindle"

Extra details from original publication
The genus Stylatractus differs from Lithatractus in the double medullary shell, from Amphisphaera in the ellipsoidal form of the cortical shell. As in these two genera, both opposite polar spines have the same shape and size.

[Synonymized with Amphisphaera by Petrushevskaya, 1975c, p.570]
