diagnosis
Diagnosis (modified from Kaiser & Brandt 2007): Body flattened and broadened; pereon and pleotelson expanded laterally in flat, marginal flanges. Pereonites without ventral spines. Rostral crest often well developed. Marginal flanges of pereonites 1 – 4 anteriorly produced. Antennula with 6 articles (only A. chelus Kaiser & Brandt, 2007, and male of Austroniscus brandtae n. sp. with 7 articles), terminal article unspecialised, not enlarged. Pereopod I somewhat shorter and distally more robust than pereopods II – VII; pereopods V – VII not especially expanded for swimming, with few natatory setae. Pleotelson without posterolateral spines. Operculum rectangular, covering a small part of the pleotelson ventral surface, width less than half pleotelson width, without ventral spines. Uropods hardly projecting above posterior margin, biramous, endo- and exopod almost of same length.
