Holotype.—Axial section (No. 476/8 Museumof the Geological Direction of the Urals) from the early Givetian of the central Urals, Russia (Pronina, 1960, pl. 1, fig. 5).


Diagnosis.—Relatively large species characterized by numer- ous necks, regularly, radially arranged. Necks short, papilliform. Wall thin, bilayered, dark-microgranular and clear- pseudofibrous.


Occurrence.—Eifelian–early Givetian of the central Urals and Givetian of the northern Urals (Pronina, 1960; Petrova, 1981), Zeravshano-Gissar (Lavrusevich et al., 1979), and Siberia (Zadorozhnyi, 1985, 1987). Givetian of Mount Polinik (Carnic Alps, Austria).


Description.—Outer diameter=0.27–0.50mm (type material: 0.34–0.52mm); inner diameter=0.15–0.37mm; number of necks: 13–15; length of necks=0.01–0.06mm (for a wall of 0.015mm); test wall thickness=0.01mm (type material: 0.01mm).


Materials.—Eight specimens (samples POL11a-6, POL11b-5, POL13a-1, POL13a-7).

Diagnosis.—Test free, moderate in size, globular with many tubular projections; thin wall dark-microgranular. One areal aperture at the end of each projection.


Occurrence.—Late Silurian, Early–Middle Devonian, Late Devonian (Frasnian–early Famennian), early Tournaisian of Russian Platform, the Urals, western Siberia, Tian Shan (Tajikistan), South China, Spain, western and northern France, ?Germany (see Vachard, 1991). Discovered in the Givetian of Austria.


Remarks.—Many Bykovaella of the literature have been desig- nated by Parathurammina (partim), Thurammina (partim), Salpingothurammina (partim), and Polygonella (partim).
