Fig. 75A–G View Fig .

Material.—Several thousand internal moulds, including figured SMNH X3707, 3712, 3713, 6020–6023, from samples 1/45 (section 1, Fig. 4 View Fig ), K2/21, K2/22, K2/23, K2/24, K2/25, 3/12, 3/12.2, 3/12.5 (section 3, Fig. 3), 5/10, 5/10B, 5a/1.2, 5a/5 (sections 96-5 and 96-5a, Fig. 2 View Fig ), Medvezhya and Emyaksin formations, Anabar Uplift, Siberian Platform, Russia (SOM 1). Correlated with the uppermost Fortunian Stage.

Description.—Thecae up to 2 mm long, laterally flattened and curved in one plane, with two shallow, wide longitudinal depressions. Cross-section ovoid in later growth stage but rounded triangular apically.

Remarks.—See Kouchinsky et al. (2009) for discussion of the validity of the species and Kouchinsky et al. (2015a) for probable lower part of Cambrian Stage 3 occurrence in the Emyaksin Formation.

Stratigraphic and geographic range.— Upper Fortunian Stage–Cambrian Stage 2 and probably lower part of Cambrian Stage 3, Siberian Platform (Kouchinsky et al. 2015a).
