original illustrations indicate a male in which the seventh pereopod has developed secondary sexual characteristics but the second antenna is still slender. His material came from the ‘shores of Illawarra’. We have never collected a species like this from the modern day Illawarra area, but we have collected one from farther north at Valla Beach and Nambucca.

is differentiated from all other talitrid amphipods by the unique setae on the merus and carpus of the male, known here as T-setae. T-setae are long, slender setae in which the distal tip is expanded to form a Tshaped structure. Although they occur only in adult males it is difficult to postulate their functionality.

during the three final molts are as follows: the antepenultimate stage has no change in pereopods 6 or 7 nor to antenna 2. In the penultimate molt antenna 2 becomes slightly incrassate and pereopod 6 develops T-setae, but there is no change to pereopod 7. In the final molt pereopod 6 develops many T-setae on the merus and carpus and in pereopod 7 the merus and carpus expand and the carpus develops medial robust setae.
