Remarks. Australokaskia (Planilobus) noorooensis strongly resembles Australokaskia (Planilobus) constricta Engel & Morris 1995 . The glabella, particularly L1, in both species is similar in convexity and shape. The difference between the two species can be seen in the pygidia. Australokaskia (Planilobus) constricta has a distinctive constriction on its axial region in all specimens, whereas only a faint constriction can be seen in some of the specimens of A. (Planilobus) noorooensis . The pygidium of A. constricta is also longer, with more axial rings and pleural ribs than in A. (Planilobus) noorooensis .
