Ceramaster also displays morphological overlap with other similar goniasterid genera, such as Peltaster (Clark and Downey, 1992; Halpern, 1970b) which further confuses boundaries between the two genera and among species in each genus.

Ceramaster includes many nominal species, such as Ceramaster patagonicus , Ceramaster grenadensis , and Ceramaster granularis that display morphological intergradation with few discrete differences.
