Cnemidocarpa completa Kott, 1985

Cnemidocarpa completa Kott 1985, p 124.

Distribution

Previously recorded (see Kott 1985): Victoria (Deal I., Bass Strait); New South Wales (Arrawarra). New record: Tasmania (Port Davey, Bathurst Channel, 3–37 m, SAM E2879–81).

Description

The newly recorded specimens were attached to clumps of Pyura irregularis on a vertical rock wall. The individuals are conical with terminal branchial apertures and atrial apertures on short siphons halfway down the dorsum. The test is thin and flexible, encrusted with sand on the upper half, which has a warty appearance, the lower half being smooth and rounded. On the left are three to six gonads. Sometimes the anterior one divides and both branches continue around the pole of the gut loop. Seven to nine gonads are on the right. The body wall is thin and the branchial sac and gut, gonads, and endocarps are as previously described.

Remarks

The new record confirms the temperate range of this species, which previously was known from Bass Strait to Arrawarra on the central New South Wales coast.
