Taxonomy and nomenclature of Triassic meandrospiral
foraminifers have been confused for a long time and they
have been misinterpreted to relate to Cretaceous Meandrospira
in most studies. We comprehensively reviewed their
research history, considering morphology, phylogenetic relation,
taxonomy, and nomenclature. This allowed us to confirm
their original porcelaneous wall composition based on wellpreserved
specimens, and to legitimize the use of the generic
name Citaella Premoli Silva, 1964 for Triassic meandrospiral
foraminifers. Citaella is here redefined as a miliolate genus
having a porcelaneous shell and typicalmeandrospiral arrangement
in its tubular deuteroloculus. The genus is restricted in
the late Early to early Middle Triassic (Olenekian–Anisian)
of the Tethyan realm. It was likely derived from a cornuspiroidean
ancestor in earliestTriassic time, although the ancestral
taxon is still unclear. Citaella gave rise to two descendant
genera, Meandrospiranella and Turriglomina, in the early–
middle Anisian. These three taxa formed a single phylogenetic
clade in the Triassic, to which the subfamily Turriglomininae
Zaninetti 1987 is best applicable. Citaella is phylogenetically
distinct fromits homeomorphicmiliolate genera Streblospira in
the Early Permian and Meandrospira in the Early Cretaceous,
although they have the same wall compositions and very similar
arrangement patterns in deuteroloculi. After scrutinizing literature,
we recognized four distinct species in the genus Citaella
including one with questionable generic assignment. We also
made taxonomic emendation of the subfamily Turriglomininae
and the genus Citaella, and demonstrated nomenclatural
precedency of Citaella pusilla over other synonymous species
that were proposed simultaneously in the same article.
