Type species. Linguaphillipsia terapaiensis Stubblefield 1948 .

Emended diagnosis. Glabella bell-shaped, constricted at γ; weakly to moderately inflated; length reaching or extending over the anterior border, not reaching the margin; S1–S3 well developed, S4 only in some species. Anterior border of variable width, generally broad; anterior furrow present; border concave with distinct terrace ridges; eyes large; facial suture lacking a straight ε – ζ section; long to short genal spines. Pygidium with 12–20 axial rings, 9–15 pleural ribs; pleural furrows clearly developed; border wide to moderately narrow, sharply set off from pleurae with or with a furrow; ribs stop short of border.

Remarks. Due to the large number of species that have been assigned to Linguaphillipsia (listed below), the original generic diagnosis by Stubblefield (1948) has been emended a number of times (e.g., Hahn & Hahn 1972,1973; Engel & Morris 1975). Australian species of Linguaphillipsia are herein retained within this broad generic concept until a detailed revision of all species is conducted. The emended diagnosis is modified from Engel & Morris (1975).
