Linguaphillipsia parvula Engel & Morris 1996

1996 Linguaphillipsia parvula Engel & Morris ; p. 129–130, pl. 2, figs. 9–18, text-fig. 6.

Holotype. AMF97019a/b (external/internal moulds of cranidium).

Paratype material. From NU L39: AMF97020 (external librigena), AMF97021 (external librigena), AMF97022a/b (external/internal pygidium), AMF97023 (external pygidium and librigena), AMF97024 (external pygidium), AMF98025 (internal pygidium), AMF97026 (external pygidium), AMF97027 (external pygidium), AMF97028 (external pygidium), AMF97029 (internal pygidium). From NU L1054: AMF97030 (internal librigena), AMF97031a/b (external/internal pygidium), AMF97032 (external pygidium).

Locality. Type—NU L39. Other—NU L1054.

Emended diagnosis. Eyes long, posteriorly placed; S1 distinct, obliquely placed; L1 short and wide. Pygidium triangular, with 11–13 axial rings, 7 pleural ribs; posterior rings and ribs poorly defined.

Remarks. As is stated above, the glabella of Linguaphillipsia parvula does not cross the anterior border furrow, which differs from the original generic diagnosis of Linguaphillipsia . In comparison to the other Australian species of Linguaphillipsia , specimens of L. parvula are very small. Engel & Morris (1996) include this in their diagnosis and claim they are distinguished from other species by their size, but as size should not be used as defining characteristic it has been removed from the diagnosis. The triangular pygidium and short glabella make it easily distinguishable from other Linguaphillipsia species in Australia.
