Brachymetopus (Brachymetopus) intermedius Engel & Morris 1992

1918 Brachymetopus dunstani Mitchell ; pl. 49, fig. 1, pl. 52, fig. 1.

1918 Brachymetopus sp. indet.; Mitchell, p. 488.

1992 Brachymetopus (Brachymetopus) maccoyi intermedius Engel & Morris ; p. 78–80, pl. 1, figs. 10–15, text-figs. 3–4.

Holotype. QGSF 1011 (external mould of partial cephalon).

Paratype material. From NU L1049: AMF84316a/b (external/internal cephalon), AMF84317a/b (external/ internal cephalon), AMF84318 (external pygidium), AMF84319 (external pygidium), From QGS L3004: QMF2839(2) (4 partial internal pygidia).

Locality. Type—QGS L3004. Other—NU L 1049.

Emended diagnosis. Glabella just over half cephalic length, tapers anteriorly; coarse nodular ornament, two rows of nodes on the cephalic border; anterior border furrow distinct and wide. Pygidium with 12 axial rings, 7 pleural ribs; marginal spines developed onto pygidial border.

Remarks. Brachymetopus (Brachymetopus) intermedius has been distinguished as a separate species from Brachymetopus (Brachymetopus) maccoyi due to its smaller eye size and coarser cephalic and pygidial ornament. The above diagnosis has been emended to exclude much of Engel & Morris’s (1992) discussion of ornament, just highlighting the size of the nodules.
