v. 2013 b Palaeonubecularia sp. ; Vachard, Krainer and Lucas, p. 348 (no illustration).

Description. No initial glomospiral stage known; the tube is immediately serpentiform. Sutures absent but tube limits very visible. Whorls relatively numerous but difficult to estimate exactly. Lateral sides of spire inflated. Peripheral margin round. Aperture not observed. L = 1.25-2.50 mm; H = 0.68-0.75 mm; h = 0.08-0.25 mm; s = 0.03/ 0.05 mm.

Remark. Similar in its dimensions to P. rustica , this taxon differs by the thinner wall and the less elongate lumen.

Occurrence. Early?-late? Kungurian (Leonardian) of New Mexico (Yeso Group: samples MG 10-26a, MG 10-28, MG 10-29, MG 10-5, MG 12 7a, MG(2) 12 10. San Andres Fm: samples MLY(2) 5-19, MLY(2) 5-22, MLY 5-29, MLY 6-24, SAR 20).
