Lectotype. QMF17–1234a/b (half internal/external moulds of dorsal shield).

Paralectotype. QMF17–1233 (external pygidium).

Locality. NU L 1064.

Emended diagnosis. Glabella conical, widest close to occipital furrow, distinct S1–S3; eyes long and wide; genal spines long. Pygidial pleural grooves extend to margin (faint at posterior); 11–12 axial rings; sub-cylindrical shape.

Remarks. Carbonocoryphe ? rockhamptonensis was reassigned to Aprathia by Engel & Morris (1989), after elevating the subgenus Carbonocoryphe ( Aprathia) to generic rank. However, the placement of this species within the genus is thought to be suspect (G. Hahn, pers. comm. 2011). Carbonocoryphe ? rockhamptonensis does not closely resemble any other Carboniferous genus found within Australia, or in fact any other phillipsiid, making it difficult to assign this species to a genus with confidence. The species has been provisionally placed within Carbonocoryphe , due to its similar pygidial characters..
