Original Description

Diagnosis. Test triserial, biserial, or trochospiral, or mixed triserial-biserial, triserial-trochospiral, or biserial-streptospiral. Microperforate to finely perforate. Wall surface smooth, pore-mounded, rugose, hispid or pustulate. Wall hyaline calcitic

Extra details from original publication
Superfamilies included. Cassigerinelloidea Bolli, Loeblich & Tappan, 1957; Guembelitrioidea Montanaro- Gallitelli, 1957; Chiloguembelinoidea Reiss, 1963; Globoconusoidea BouDagher-Fadel, 2012.

Justification: 
Fursenko (1958) joined all planktic foraminifera with bi- and triserial arrangement, at least in the early ontogenetic stage, in the order Heterohelicida, consequently clustering the families Heterohelicidae Cushman, 1927, Guembelitriidae Montanaro-Gallitelli, 1957, Chiloguembelinidae Loeblich & Tappan, 1956, Globoconusidae BouDagher-Fadel, 2012, and Cassigerinellidae Bolli, Loeblich & Tappan, 1957 (see BouDagher-Fadel, 2012, 2015). However, this order also becomes polyphyletic if the guembelitriids and their Cenozoic descendants (chiloguembelinids, globoconusids and cassigerinellids) are included. It is therefore necessary to separate these families in a new order, which we have called Guembelitriida, because the genus Guembelitria, and the family Guembelitriidae Montanaro-Gallitelli, 1957, are the ones that best characterize it. Consequently, it is also necessary to emend the order Heterohelicida. Guembelitriida n. ord. includes 4 families: Cassigerinellidae, Chiloguembelinidae, Globoconusidae and Guembelitriidae (Fig. 2), which we have also elevated to the category of superfamily.
