Kott 2003 , p 1619 and synonymy (part, not specimens from Queensland = Distaplia turboensis Kott 2004 , p 45 ). Distribution Previously recorded (see Kott 2003 and D. turboensis Kott, 2004 ): South Australia (Spencer Gulf, Gulf St Vincent, Bass Strait, D’Entrecasteaux Channel, Huon Channel. New records: South Australia (Kangaroo I., 4–7 m , SAM E3294–5). Description Long cylindrical stalks each with a soft, rounded head surrounded by parallel double rows of zooids extending from the top of the stalk to a terminal common cloacal aperture. Zooids have the usual large atrial aperture opening directly into the vertical common cloacal canal between each row of zooids of the pair. The stomach wall has about 16 parallel longitudinal pleats. Gonads were not detected in the newly recorded colonies, although usually they are in a sac separated from the abdomen by a narrow constriction. Remarks Although the arrangement of the zooids in long vertical rows and the presence of the gonads in a posterior abdomen is similar to the tropical Distaplia turboensis , the present species is distinguished by its long cylindrical stalks and fewer stomach folds.
