Sister taxa: C. alta, C. clipeus, C. erbae, C. oblongata, C. sp.,

Distinguishing features: Calcicalathina with a low central area showing sharp distinction between rim (1st order yellow birefringence) and coarsely-granular central area


Taxonomy:

Citation: Calcicalathina erbae Bergen 1998
Rank: Species
Synonyms: Calcicalathina sp. A Bergen 1994
Calcicalathina praeoblongata Aguado in Aguado et al. (2000) [both Bergen 1998 and Aguado et al. 2000 included Calcicalathina sp. A of Bergen 1994 in their synonymy, so it seems they are describing the same species - JRY April 2015]
