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

Description. Test cuneate to tongue-shaped, moderately elongate (H = 0.50 mm; w = 0.12 mm; w/H = 0.24). Proloculus terminal, not prominent, spherical (0.03 mm in diameter). Six chambers from small crescentiform to high spear-shaped crescentiform (h = 0.11 mm). Wall thin (s = 0.01 mm).

Remark. Nodosaria polonica Wozsczynska, 1987 is relatively similar in shape although smaller (H = 0.36 mm and w = 0.08-0.11 mm) for 6-8 chambers.

Occurrence. Middle? Kungurian (late Leonardian) of New Mexico (San Andres Fm: sample MLY 3-5).
