Carapace smooth, not covered with setae; pseudorostral lobes without carinae. Uropod rami longer than or equal to uropod peduncle; uropod endopod triarticulate. Telson more than 0.5 uropod peduncle length. Body length females up to 2.3 mm, males unknown.
Cumaceans burrow into the surface of sandy and muddy sediments but can also be found in the sediment trapped among macroalgae. At night especially cumaceans can be active swimmers in the open water and this is probably where mating occurs. Females carry the eggs in a marsupium made from branches of the thoracic legs, making the front of the animal more swollen than normal. The eggs hatch as miniature adults.
Soft bottom from rock and coral sand, at depths of 8-112 m.
Southern temperate oceans, including south-eastern Australia.
