Polycarpa chinensis ( Tokioka, 1967)  

Cnemidocarpa chinensis Tokioka 1967, p 188   .

Polycarpa chinensis: Kott 1985, p 157   and synonymy.

Distribution

Previously recorded (see Kott 1985): Western Australia (Dampier Archipelago to Cockburn Sound); Victoria (Bass Strait); Queensland (Moreton Bay to Murray I.), China (Tsia-men), Vietnam. New records: Queensland (16.235 –18.815 ° S, 145.955– 146.955 ° E, 12–60 m) GoogleMaps   .

Remarks

The external appearance of smaller specimens of this species often closely resembles Polycarpa procera   (see below) although the long, curved larger specimens with apertures produced on short siphons can be confidently assigned to the present species. These two species are often sympatric and both are found over a great tropical-temperate range— P. chinensis   from the South China Sea to Cockburn Sound and Bass Strait, and P. procera   with an even wider north–south range from Japan to South Australia.

The present species is also one of the most frequently encountered species in the benthic fauna of the sea floor of north-eastern Queensland, occurring in about one-third of the stations at which ascidians were taken, only Polycarpa decipiens   and Herdmania grandis   being recorded more often. Polycarpa papillata   is also recorded at about one-third of the stations, but in much smaller numbers than the present species.

Polycarpa flava Kott, 1985  

Polycarpa flava Kott 1985, p 165   and synonymy.

Distribution

Previously recorded (see Kott 1985): South Australia (Great Australian Bight, Spencer and St Vincent Gulf, Kingston); Victoria (Point Nepean, Cape Woolamai, Bass Strait). Tasmania (Orford). New records: Tasmanian Canyons (King I. Canyon, 249 m, 348 m; Banks Strait, 168 m)   .

Description

The body shape is variable in this species, sometimes being stalked, and other specimens being sessile, fixed by basal roots and props. The test is dark brown in preservative and a thin layer of sand is in the surface. Large colourless vesicles are in the muscular body wall, the gut always enclosed a teardrop-shaped endocarp, small rounded lobes are around the anal rim and flask-shaped gonads are in the pallial body wall.

Remarks

The species appears to be a common component of the benthic fauna in the southeastern part of the continent. It is distinguished mainly from other robust species in the pedunculata   group of this genus by its black to black-brown colour.
