This species differs very slightly from Tliorell's and L. Koch's description of Isopeda pessleri Thor. But it has no transverse stripe behind the genital fold. In the Adelaide specimens the front side-eyes in the female, as in the male, are somewhat larger than the median, and the latter nearer to the side than to one another. Two spines above on tibia iii. and iv. instead of one. In the Kangaroo Island female the front row eyes are all equal, and tibia iv. has only one spine, which brings it still nearer to I. pessleri. The cephalothorax is red-brown; the mandibles, lip, and sternum black-brown with yellowish hair and bristles. The sternum is black, with black hair extending over the two front coxec and partially over the two rear. The abdomen is yellowish-brown, with rather coarse matted hair, three pairs of muscle-spots showing on the upper side, and a slightly impressed shield-pattern on the under.
