Australokaskia similis Engel & Morris 1995

1995 Australokaskia (Longilobus) similis Engel & Morris ; p. 194–196, pl. 1, figs. 1–9.

Holotype. AMF90339a/b (external/internal moulds of cephalon missing one librigena).

Paratype material. AMF80340a/b (external/internal dorsal shield), AMF80340c/d (external/internal librigena), AMF90340e/f (external/internal partial cranidium), AMF 90340 g/h (external/internal dorsal shield), AMF90341a/b (external/internal dorsal shield), AMF90342a/b (external/internal pygidium and thorax), AMF90343 (internal pygidium and external librigena), AMF90344 (external pygidium), AMF90345 (external pygidium).

Locality. Type—NU L448.

Emended diagnosis. Moderately convex, glabella slightly narrows anteriorly, extends to anterior margin; L1 long, triangular; eyes long; lateral border steeply inclined; genal angles rounded or with very short genal spines. Pygidium with 11 axial rings, 7 pleural ribs; ribs equal width; single row of nodes along rings.

Remarks. Engel & Morris (1995) remarked in their original diagnosis that S2 and S3 are present, albeit weak. However, neither S2 or S3 are present on external specimens and so have been omitted from the diagnosis. An antennal pore was also included in the original diagnosis but has been removed as it also cannot be seen in the specimens.
