1975 Linguaphillipsia elongata rouchelensis ; Engel & Morris, p. 170–173, pl. 2, figs. 17–21.

Lectotype. AMF35855 (internal mould of pygidium).

Paralectotype material. AMF35696 (internal pygidium), AMF35747 (internal pygidium), AMF35850 (internal pygidium).

Locality. Type—Given only as Binge Berry Rouchel Brook NSW in Engel & Morris (1975). Emended diagnosis. Pygidium with 18–19 axial rings, 14 pleural ribs; convex pygidial border; elongated semi-circular shape.

Remarks. Engel & Morris (1975) re-diagnosed the species Phillipsia rouchelensis Mitchell 1918 as a subspecies of Linguaphillipsia elongata . No cephala were ever found for L. elongata rouchelensis , making comparisons difficult. The material of L. elongata rouchelensis described by Engel & Morris has a semi-circularshaped pygidium, fewer pygidial axial rings and pleural ribs, and a wider, more convex pygidial border, compared with specimens of L. elongata elongata . Based on these differences in the pygidia, the two subspecies have been elevated to species rank herein.
