Classification: pf_cenozoic -> Truncorotaloididae -> Alicantina
Sister taxa: Alicantina, Acarinina, Praemurica ⟩⟨ Igorina, Pearsonites, Planorotalites, Astrorotalia ⟩⟨ Morozovella, Morozovelloides
Daughter taxa: (blue => in age window 0-800Ma)
Alicantina prolata
Like A. lozanoi but test smaller with 4–5 chambers in the final whorl, looser coiling and a lower spire.
Alicantina lozanoi
Moderately high, evolute, trochospiral test, 5-6 globular chambers in final whorl; predominantly, intraumbilical aperture.


Citation: Alicantina Soldan et al. 2018
Rank: Genus
Taxonomic discussion: The genus Alicantina was proposed by Soldan et al. 2018 for a pair of species (lozanoi) tentatively included in Praemurica by Breggren et al. 2006. They further argued that G. prolata which had been included in P. lozanoi by Berggren et al. 2006 was a discrete species, also assignable to their new genus Alicantina. [editor's comment - JRY 2019]

Catalog entries: Alicantina

NB These concise distinguishing features statements are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus.
They are being edited as the site is developed and comments on them are especially welcome.


Wall type: Non-spinose, dutertrei-type, irregularly cancellate.

Biogeography and Palaeobiology

Phylogenetic relations:

Alicantina n. gen. evolved in the early Eocene presumably from a parasubbotinid-like taxon possessing a non-spinose wall texture and left no descendants. [Soldan et al. 2018]
