1918 Phillipsia rockhamptonensis Mitchell ; p. 495–461, pl. 49, figs. 9–10, pl. 50, fig. 8. 1963 Conophillipsia? sp.; Campbell & Engel, pl. 8, figs. 1–2.

1972 Phillipsia ( Phillipsia ?) rockhamptonensis ; Hahn & Hahn, p. 400. 1989 Aprathia rockhamptonensis ; Engel & Morris, p. 327–332, figs. 11–12.

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..
