Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. R. Loeblich and H. Tappan 1982 | The subfamily was elevated to family status by Saidova (1981) who also recognised the superfamily Spiroplectamminidea for taxa with simple walls (in contrast to the Tawitawiidea, with internal pillars), but included within it the families Spiroplectamminidae, Textulariidae, Plectorecurvoididae, Morulaeplectidae and Nouriidae. As all family group taxa are of equivalent status for purposes of priority, the family group name Textulariidae Ehrenberg, 1838 has priority for superfamily status. The family Spiroplectamminidae was stated (Saidova, 1981) to have a planispiral early stage followed by a biserial or straight uniserial stage. Banner and Pereira (1981) also defined the family as having an initial planispire and later biserial stage, but lacking a terminal uniserial stage. IT is also characterised by a solid wall without canaliculi or pseudopores. Although Semivulvulina, which possesses these structures was thought to have evolved from Spirorutilis in the Eocene, and was included by Banner and Pereira in the Spiroplectamminidae pending further study, we would restrict the family to include only those taxa with solid walls. |
