Distinguishing features: Parent taxon (Tenuitella): Minute to small, low trochospiral test, with globular chambers. Monolamellar, microperforate wall with a smooth or finely pustulate surface. This taxon: Specimens which cannot be assigned to established species
NB These concise distinguishing features statements are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus. They are being edited as the site is developed and comments on them are especially welcome.
