K&J REMARKS It appears that this name was not validly published because the author did not specify where the holotype is stored, and did not provide a Latin or English translation. (ICBN, Art. 36.3.)

The illustrated specimens (l.c., figs. 13, 14, 16) have a diameter of 50-70 μm, and show a vague similarity to our Pl. 21, figs. 1 and 3 (Phragmothyrites cooksoniae (Rao & Ramanujam) comb. nov. and P. otozamiticola (Krassilov) comb. nov., resp.), but with the radial septa wandering and anastomozing, delineating coarse fields (or cells?).
