Paleonet: Globoturborotalita?

[Robert L. Fleisher]

Both Globoturborotalita (type species: Globigerina rubescens) and 
Zeaglobigerina (type species: Globigerina woodi) are names that have 
been applied to species in a distinct lineage of primarily Neogene 
globigerinids, morphologically characterized by compact tests, a 
distinct apertural lip or rim, and in particular, a cancellate wall 
texture.  Globigerina nepenthes is also a member of this lineage, which 
has been phylogenetically distinct from Globigerina s.s. (which 
possesses a spinose non-cancellate wall) since at least the Oligocene 
and probably earlier.  Globoturborotalia is the senior synonym.
