Original Description
Cephalis very small, subspherical, hyaline, without pores. Thorax flatly conical or hat-shaped, with concave lateral outlines, and a very delicate network of small square meshes (similar to Litharachnium araneosum, Pl. 55, fig 8). This is supported by thirty-two curved radial ribs, four of which are primary, four secondary, and the other twenty-four interpolated. Peristome horizontally expanded and little recurved, like the reflexed brim of a hat

Size: Cephalis 0.12 diameter; thorax 0.08 long, 0.24 broad.

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Sethophormis leptopilium under the subgeneric name Astrophormis, but did not include the subgeneric name in the species name.[comment from RadWorld database]
