Diagnosis.—Medium-sized Parathuramminidae with very thin wall and very long necks, wall unilayered dark- microgranular.


Occurrence.—Eifelian of the Tomsk area, SW Siberia (Makar- enko and Savina, 2013). Givetian of Austria (this study). Givetian–Frasnian of South China. Givetian–Tournaisian of Tian Shan (Kyrgyzstan). Frasnian–Famennian of Poland, east- ern part of Russian Platform, the Urals, SW Siberia, and southern Fergana.

Holotype.—Fig. 10.28 (POL11b-24); Institute of Geology, University of Innsbruck, Cat. Nr. P 10140-POL 11b (thin sec- tion); Givetian Feldkogel Limestone (Polinik Formation) of Mount Polinik (Austria).


Diagnosis.—A species of Radiosphaerella characterized by a few necks communicating with each angle of the subpentagonal inner chamber.


Occurrence.—?Eifelian–early Givetian of the Urals. ?Givetian of Morocco. Givetian and Frasnian of southern Fer- gana. Frasnian of Vietnam. Famennian of Russian Platform. Discovered in the Givetian of Mount Polinik (Carnic Alps, Austria).


Description.—Outer diameter=0.10–0.17 (0.35 mm); inner diameter=0.07–0.11mm; number of necks: 1–4 (5?); test wall thickness=0.007–0.01mm.


Etymology.—Named in honor of B.V. Poyarkov.


Materials.—10 specimens (samples POL11a-11, POL11a-17, POL11a-22, POL11b-24, POL11a-25a).


Remarks.—Differs from Parathurammina radiosphaerica by fewer necks (up to seven for P. radiosphaerica) for similar measurements.
