Original Description Diagnosis - Test trochospiral, or mixed trochospiral- triserial. Microperforate to finely perforate. Wall surface smooth. Extra details from original publication Genera included. Pseudocaucasina Arenillas & Arz, 2016 in Arenillas & Arz (2017); Palaeoglobigerina Arenillas, Arz & Náñez, 2007; Parvularugoglobigerina Hofker, 1978.
Justification: In addition to proposing that Pseudocaucasina was the first Cenozoic globigerinid genus to appear, Arenillas and Arz (2017) were in favour of including this genus in a new ancestral Cenozoic family of the order Globigerinida together with Parvularugoglobigerina and Palaeoglobigerina Arenillas, Arz & Náñez, 2007. Until now, these taxa have been informally termed parvularugoglobigerinids. They gather the tiny species with microperforate, smooth wall discovered by Luterbacher and Premoli-Silva (1964) immediately above the KPB (also see Arenillas & Arz, 2000). We here group these primitive Cenozoic taxa into the new family Parvularuglobigerinidae, because Parvularugoglobigerina is the genus that best characterizes it. The parvularugoglobigerinids cannot be included in the family Eoglobigerinidae Blow, 1979, or in the family Globanomalinidae Loeblich & Tappan, 1984, because they are the ancestral forms of both, and do not conform to the wall-texture characteristics of either of them (Figs. 3, 4). Consequently, it is also necessary to separate them into a new superfamily (Parvularuglobigerinoidea) to differentiate them from superfamilies Eoglobigerinoidea BouDagher-Fadel, 2012, and Globanomalinidoidea Loeblich & Tappan, 1984.
