Original Description
Cephalis large, subspherical, with circular, subregular, hexagonally framed pores, and twenty to thirty slender, cylindrical, straight radial spines. Thorax flatly conical, nearly of the same shape as in the two preceding species, but with nine longer ribs, and more irregular, broader network between them. From the middle of each rib arises, nearly horizontally, a strong branch, which is directed outwards. These branches are connected with the spines of the cephalis as well as with the distal half of the ribs, by dense and delicate arachnoidal network, composed of parallel, very thin, siliceous threads (in fig. 11 only partially represented). Collar septum with numerous irregular, roundish pores.

Size: Cephalis 0.04 diameter, thorax 0.1 long, 0.2 broad.

Editors' Notes
Haeckel listed Arachnocorys araneosa under the subgeneric name Arachnocoronium, but did not include the subgeneric name in the species name.
In the description the \two preceding species\" refers to Arachnocorys circumtexta and A. enneaptera in Haeckel, 1887a.
See Arachnocorys arachnodiscus and A. polyptera in Haeckel, 1887a.
