Original Description
Cephalis large, subspherical, with irregular, roundish pores and numerous radial spines. Thorax flatly conical, with numerous radial ribs (twenty to thirty), which are in the distal half free, in the proximal half connected by delicate arachnoidal wicker-work, with polygonal, irregular meshes. From its dorsal face arise numerous radial spines, which are connected together, and with the cephalic spines, by very thin and numerous threads, parallel between every two spines. Similar to Arachnocorys araneosa (Pl. 56, fig. 11), but differing in the structure of the cephalis, and in the greater number of the ribs and spines.

Size: Cephalis 40µm diameter, thorax 120µm long, 240µm broad.

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