Remarks. The two Australian species of Namuropyge differ from other species in that they do not possess two rows of marginal cephalic spines, where the vertical row of spines is missing. They differ from one another in that N. australis has longer, wider and more elevated eyes, and longer cephalic spines. The marginal pygidial spines of N. australis are horizontal, whereas they are vertical in N. uniserialis ( Engel & Morris 1991) .
