Species
Belonechitina intonsa Nõlvak et Bauert, 2015
Taxon description
Nõlvak & Bauert, G., 2015
Belonechitina intonsa has sometimes a subcylindrical chamber, whereas the maximum chamber diameter is observed near the basal margin. The vesicle wall and the base are covered with short simple spines of similar length. In cases of poor preservation (when the spines are removed) it may be difficult to distinguish B. intonsa from C. viruana
