Diagnosis. Telson anterolateral margin in male extending broadly to a small notch, with a solid, thickened tonguelike lobe protruding posterolaterally and dorsally, ornamented with parallel ridges. Pereopodal 2–4 dactyli 7.0–7.6 times as long as greatest basal width; robust setae on dactylus of pereopod 2 number 3–13 (low numbers exceptional, median 10); pereopod 3, 1–6 (median 3); and of pereopod 4, 1–3 (median 1). Pereopod 4 merus without spines on upper face.

Distribution. Taiwan, New Caledonia, Loyalty Islands, Vanuatu, eastern (S to 42°S) and western margins (S to 23°S) of Australia; 275–754 m (median 439 m) depth.

Remarks. Agononida rubrizonata is easily recognised even as juveniles. The dominant lobes extending from the anterolateral margin of the telson of males are obvious but even in the smallest females and juveniles this margin ends posteriorly in an acute overlapping projection unlike that in any other species. Additional material seen during the course of this study did not extend its biogeographic range. Agononida rubrizonata was recovered sister to A. auscerta within clade B in all molecular analyses.
