Aplidium robustum Kott 1992a, p 582 View in CoL .

Distribution

Previously recorded ( Kott 1992a): Western Australia (King George Sound); South Australia (Great Australian Bight); Tasmania (Dunalley). New records: Tasmania (Bass Strait, 70 m, QM G308806–7 ) .

Remarks

The newly recorded colonies are identical with those previously assigned to the species, being soft, irregular, fleshy masses with sand embedded only in the base. The crowded zooids, their long, narrow thoraces, orange in preservative and with about 20 longitudinal folds in the small stomach, are arranged in circular systems. The soft test contains white, opaque corpuscles in the layer that closely surrounds the zooids. The newly recorded zooids have the atrial tongue separate from the aperture, although this has not previously been reported for this species. The species resembles A. multiplicatum Sluiter, 1909 although the larvae and the cloacal systems are different (see Kott 1992a).
