Classification: ntax_mesozoic -> Podorhabdales -> Cretarhabdaceae -> Miravetesina
Sister taxa: Mattiolia, Wisea ⟩⟨ Speetonia ⟩⟨ Cruciellipsis, Flabellites, Grantarhabdus, Helenea ⟩⟨ Cretarhabdus, Retecapsa, Pickelhaube, Miravetesina

Distinguishing features: Cretarhabdids with central area spanned by narrow axial cross and fine net.

Daughter taxa (time control age-window is: 0-800Ma)
				Miravetesina bergenii Like M. favula but medium-sized (6-8 µm), with more pronounced axial cross, and younger age. Late Creteceous
				Miravetesina favula Large (7-12 µm) cretarhabdids with central area spanned by narrow axial cross and fine net. Late Jurassic-Early Cretaceous
				Miravetesina sp. Specimens not identified to species level
