1996 Bollandia (Capricornia) queenslandica Engel & Morris ; p. 126–127, pl. 3, figs. 20–27, text-fig. 4.

Holotype. AMF96996 (external mould of cranidium).

Paratype material. AMF96997 (partial internal cephalon), AMF96998 (internal cranidium), AMF96999 (internal cranidium), AMF97000a/b (external/internal pygidium), AMF97001 (internal pygidium), AMF97002 (internal pygidium).

Locality. NU L 1047.

Emended diagnosis. Glabella strongly convex, parallel sided; median anterior border inflated; glabella touches border; S1–S3 developed (possibly S4?); L1–L3 developed (possibly L4?); S1 and S2 deep, almost parallel to one another; L1 short; S3 (S4?) short. Pygidium with 11 axial rings, 5–6 pleural ribs; nodular ornament on pygidial axis.

Remarks. Specimens of Bollandia ? queenslandica are very small and poorly preserved. They are difficult to place into a genus. The species is tentatively kept within the genus Bollandia due to a highly arched glabella, a vertical anterior border, and strongly arched pygidium (based on the diagnosis by Hahn et al. 1984).
