Classification and/or Status

Irregularia; Cassiduloida; Cassidulidae.

Subjective junior synonym of Rhyncholampas A. Agassiz, 1869.


Kier (1962) states that Galerolampas differs from Rhyncholampas only by having a slightly inframarginal periproct, the periproct in Rhyncholampas being either marginal or slightly supramarginal. No material has been examined and much remains unknown about this taxon.
