AGE AND LOCATION OF TYPE MATERIAL. — Upper Devonian, Huron member, Ohio Shale, USA. TAXON CODE. — 229. STATUS. — Valid. DIAGNOSIS. — “Relatively large spherical or subspherical cephalis, enclosing a spicule with six to perhaps eight (commonly seven) rays arising from the ends of an oblique median bar. Thorax, perforate or imperforate, with or without marginal teeth, not separated from the cephalis by regular collar pores. The rays of the internal spicule continue beyond the wall of the cephalis, and in and beyond the wall of the cephalis, and in and beyond the thoracic wall, as external spines” (Foreman 1963: 284). REVISED DIAGNOSIS. — “A single, perforate, pylomate lattice shell with internal spicular system incorporating six or seven rays. Externally, more than four main spines, usually seven and only rarely five, two to four of which are incorporated in the pylome margin. A pylome net is sometimes present and in some species, and in some individuals of other species, it is considered that spicules are secondary lost.” (Holdsworth 1973: 122)., Published as part of Noble, Paula, Aitchison, Jonathan C., Danelian, Taniel, Dumitrica, Paulian, Maletz, Jörg, Suzuki, Noritoshi, Cuvelier, Jessie, Caridroit, Martial & O'Dogherty, Luis, 2017, Taxonomy of Paleozoic radiolarian genera, pp. 419-502 in Geodiversitas 39 (3) on page 474, DOI: 10.5252/g2017n3a4, http://zenodo.org/record/5206585, {"references":["FOREMAN H.

REMARKS Won (1997a) emended the diagnosis of Entactinosphaera to exclude two-shelled species, and erected this genus to accommodate the two-shelled forms. The name is a homonym of a fusulinid foraminifer (Bisphaera Birina, 1948), and so the replacement name Duosphaera was proposed (Won 1998).

DIAGNOSIS (English translation by Taniel Danelian). — Cephalis spherical, perforated by rounded pores that are not numerous and well-spaced, bearing four costate horns one of which is always short and conical, the two others are large and not apical. The opening is large and bears a thick collar, from which long spikes extend, they are brought together in the form of brush, with a podome that is formed by three long tri-bladed horns, which are straight or slightly curved, through which exist the remains of a pectinate (parallel-ridged) apparatus. The internal spicular (trabecular) system is known only from some remains with slender stalks extending from the base of the horns and truly directed towards the center.

The two layers are similar in thickness, but different in structure: the inner layer is comprised of large, irregular pore frames and the outer layer, of small, irregular pore frames. Numerous beams connect the two layers.” (Feng in Feng et al. 2004: 137).
