Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. Martinez-Gallego and J. Cremades 1979 | La concha esta enrollada en una trocoespira muy baja, con la cara dorsal plana y practicamente paralela a la ventral. La ultima vuelta de espira presenta de 4 a 4.5 camaras. Estas 4 camaras son sensiblemente iguales en tamano, como consecuencia de un crecimiento casi nulo.
El contorno ecuatorial es fuertemente lobulado, quedando grandes escotaduras entre cada dos camaras contiguas de la ultima vuelta de espira; la periferia axial es redondeada. Las suturas son bastante deprimidas, radiales y anchas sobre la cara umbilical; anchas y de ligeramente incurvadas a radiales, sobre la cara dorsal. Las camaras son globulosas, practicamente esfericas. Las de la ultima vuelta de espira estan dispuestas segun una trocoespira poco apretada. La ultima camara es normalmente algo mas pequena que la penultima y parece estar ligeramente retraida sobre la cara espiral en relacion al plano de enrollamiento de las camaras precedentes; sobre la cara umbilical tiende a cubrir una pequena parte de la region umbilical. El ombligo es amplio y abierto, La abertura es interiomarginal, umbilical-extraumbilical, en forma de arco bajo, y esta provista de un labio generalmente muy desarrollado. La prend es calcarea y perforada, y la superficie apanalada. | |
| R. K. Olsson et al. 2006 | Type of wall: Cancellate, normal perforate, high porosity, reticulated Clavigerinella-type wall texture.
Test morphology: Very low trochospiral, highly lobulate, 4-41/2 chambered symmetrical test with elongate, globular to cylindrical chambers; in spiral view 4-41/2 globular/cylindrical chambers, the last 4 of almost equal size, forming a pinwheel shape of 4 opposing chambers; in umbilical view identical to the spiral view in arrangement of ultimate whorl chambers, umbilicus small, shallow, aperture a low umbilical-extraumbilical arch, bordered by broad lip; in edge view compressed, parallel sided, chambers spherical in shape. |
