Diagnostic description. Head lateral cephalic lobe large, broad, subacute or narrowly rounded in male, broadly rounded in female. Antenna 1 peduncular article 1 without anterodistal projection. Labrum, epistome and upper lip fused. Mandible palp article 2 anterodistal margin setose; article 3 with marginal and apical setae. Labium without apical stylets on each lobe. Gnathopod 1 parachelate; basis anterior margin with slender setae; propodus posterior margin smooth. Gnathopod 2 subchelate; carpus long; propodus palm transverse, slightly concave; dactylus not fitting palm. Pereopod 6 basis posteroventral margin rounded. Pereopod 7 basis, posterior margin almost straight, minutely crenate, posteroventral margin oblique (slightly concave). Epimeron 3 posteroventral corner narrowly rounded. Urosomites 1–3 dorsally smooth. Uropod 1 outer ramus slightly longer than inner ramus; uropod 2 rami subequal in length; uropod 3 rami inner ramus slightly shorter than outer ramus, almost reaching article 2 of outer ramus.

Depth range. 0– 100 m.

Remarks. Waldeckia nitens is very similar to W. australiensis and the distribution ranges of these two species overlap considerably. The most useful character for distinguishing these species is the gnathopod 2, which in W. australiensis is chelate with the dactylus always fitting the palm, while in W. nitens it is subchelate with the dactylus distinctly shorter than the palm.

Bellan-Santini & Ledoyer (1974) recorded W. chevreuxi (here placed in the synonymy of W. nitens ) from Kerguelen Island. However, we do not believe that species to be a Waldeckia as the mandibular molar does not appear to be developed, the mandibular palp has no setae, the first gnathopod is simple, the merus of pereopod 7 is not expanded, the outer ramus of uropod 3 is only 1-articulate and the rami have no plumose setae and the apical robust setae of the telson are not strongly developed.

Distribution. Australia: South Australia; Tasmania; Victoria; New South Wales.
