Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| B.W. Hayward et al. 2012 | Test free, straight to slightly arcuate; chambers uniserial, sometimes initially biserial; aperture terminal, cribrate or reticulate mesh or weakly developed cribrate network, sometimes forming a domed or conical trematophore; test wall smooth, spined or costate; lacks an internal tooth-plate between foramina. Cretaceous–middle Pleistocene.
Chrysalogoniidae differs from the Nodosariidae by the presence of a cribrate or reticulate mesh aperture; and from the Stilostomellidae by the absence of a tooth-like fold in the wall of the apertural neck, which in the Stilostomellidae is often also seen in foramina between chambers. One uniserial taxon with a cribrate aperture (Cribropleurostomella) is placed in the Ellipsoidinidae because of the presence of an internal tooth-plate. |
