No full textLeptoclinides durus Kott, 2001 Leptoclinides durus Kott, 2001: 57 and synonymy. Distribution. New record: Western Australia (52 n. mls NW of Port Hedland, WAM 798.88). Previously recorded (see Kott, 2001): Western Australia (Bonaparte Archipelago), Queensland (Capricorn Group to Dingo Reef), Arafura Sea, Micronesia. Kott (2001) notes that the species has not been recorded at less than 6 m depth. The newly recorded specimen is from 52 m. Description. The newly recorded specimen has the characteristic spicules crowded throughout and outlining the stellate branchial apertures in the surface of the sheet-like colony.Published as part of Kott, Patricia, 2004, New and little-known species of Didemnidae (Ascidiacea, Tunicata) from Australia (part I), pp. 731-774 in Journal of Natural History 38 (19) on page 734, DOI: 10.1080/00222930310001647334, http://zenodo.org/record/465368
Polycarpa flava Kott 1985
No full textPolycarpa 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.Published as part of Kott, Patricia, 2006, Observations on non-didemnid ascidians from Australian waters (1), pp. 169-234 in Journal of Natural History 40 (3 - 4) on pages 216-217, DOI: 10.1080/00222930600621601, http://zenodo.org/record/523243

Pseudodistoma gracile Kott 1992
No full textPseudodistoma gracile Kott, 1992a (Figure 9A) Pseudodistoma gracilum Kott 1992a, p 433 and synonymy. Distribution Previously recorded (see Kott 1992a): South Australia (Great Australian Bight, Investigator Group, Kangaroo I.); Victoria (Beachport, Western Port); New South Wales (Jervis Bay, Port Jackson); Queensland (Great Barrier Reef); New Caledonia. New records: South Australia (Kangaroo Is, 8–10 m, SAM E3270); Tasmania (Maria Is; Port Davey, 4– 6 m, SAM E3269). The new records from Tasmania are the most southerly locations yet recorded for this species. Description The colonies have the robust, contractile zooids of the usual form entangled in the soft, disintegrating mucus-like test as described previously. Remarks Although colonies and zooids resemble those of the Japanese P. fragile Tokioka, 1958, the present species broods only a single embryo at a time, while the Japanese species has a long brood pouch with up to five embryos being brooded at a time and a significantly longer larval trunk (see Kott 1992a). Like other species in this genus it is more often recorded from temperate locations than from tropical ones.Published as part of Kott, Patricia, 2006, Observations on non-didemnid ascidians from Australian waters (1), pp. 169-234 in Journal of Natural History 40 (3 - 4) on page 192, DOI: 10.1080/00222930600621601, http://zenodo.org/record/523243
Polycarpa intonata Kott 1985
No full textPolycarpa intonata Kott, 1985 Polycarpa intonata Kott 1985, p 168. Distribution Previously recorded (Kott 1985): Queensland (Abbot Point, Cleveland Bay). New records: Queensland (15.245 ° S, 145.435 ° E, 29 m; 15.495 ° S, 145.385 ° E, 25 m, 18.615 ° S, 146.465 ° E, 23 m). Remarks Previously the species was known only from two locations in the vicinity of Townsville and the new records extend the known range to the north (from Cooktown to Ingham). As previously described, the oval, sandy specimens, with thin sandy test, have two irregular rows of rounded ovarian sacs with their ducts directed ventrally on each side of the endostyle. Up to four specimens have been taken at each of the three newly recorded locations. The species is known to be one of the few known solitary viviparous species.Published as part of Kott, Patricia, 2006, Observations on non-didemnid ascidians from Australian waters (1), pp. 169-234 in Journal of Natural History 40 (3 - 4) on page 217, DOI: 10.1080/00222930600621601, http://zenodo.org/record/523243
Pseudodistoma inflatum Kott 1992
No full textPseudodistoma inflatum Kott, 1992 (Figure 9B) Pseudodistoma inflatum Kott 1992a, p 435. Distribution Previously recorded (see Kott 1992a): New South Wales (South Solitary Is, Byron Bay, Coff’s Harbour); Queensland (Mooloolaba). New record: New South Wales (Coff’s Harbour, 5–7 m, SAM E3297). The new record is from the restricted geographic range previously recorded for this species (from northern New South Wales to the Queensland / New South Wales border). Description The colony is small, sessile, its upper surface divided into two rounded lobes that narrow toward the base, where some sand is embedded, although there is none in the gelatinous and translucent test of the upper part of the colony.Published as part of Kott, Patricia, 2006, Observations on non-didemnid ascidians from Australian waters (1), pp. 169-234 in Journal of Natural History 40 (3 - 4) on page 192, DOI: 10.1080/00222930600621601, http://zenodo.org/record/523243
Ecteinascidia maxima Kott 1985
No full textEcteinascidia maxima Kott, 1985 Ecteinascidia maxima Kott, 1985, p 93. Distribution Previously recorded (see Kott 1985): Lord Howe I. New record: Queensland (Noosa Heads, 8–10 m, QM G308786). Remarks The newly recorded colony from the mid-eastern coast of Australia is the only one outside the type locality. The specimens are similar to the type material. Zooids are robust, with large blotches of red colour around the anterior part of the zooid, including bands of colour around the base of each protruding siphon, relatively long siphons, about 15–20 rows of stigmata and an almost continuous coat of transverse muscles on each side of the body.Published as part of Kott, Patricia, 2006, Observations on non-didemnid ascidians from Australian waters (1), pp. 169-234 in Journal of Natural History 40 (3 - 4) on page 212, DOI: 10.1080/00222930600621601, http://zenodo.org/record/523243
Herdmania mentula Kott 2002
No full textHerdmania mentula Kott, 2002 Herdmania mentula Kott 2002, p 365. Distribution Previously recorded (see Kott 2002): Western Australia (Barrow I., Rowley Shoals, Dampier Archipelago, Cape Preston, Montebello Is, North West Cape, Learmouth, Shark Bay, Cervantes). New records: Queensland (18.845 ° S, 146.795 ° E, 26 m; 17.655 ° S, 146.225 ° E, 26 m; 17.145 ° S, 146.205 ° E, 36 m). Remarks Although only one to three small specimens were taken at the newly recorded locations, these do establish that the species known formerly only from the northwestern coast of the continent also occurs on the northeastern continental shelf. The species is readily distinguished by its short muscles that do not extend over the lower half of the body, the simple bilabiate anal border with each lip subdivided, the plain-edged oviducal membrane, and projecting distal end of the vas deferens.Published as part of Kott, Patricia, 2006, Observations on non-didemnid ascidians from Australian waters (1), pp. 169-234 in Journal of Natural History 40 (3 - 4) on pages 226-230, DOI: 10.1080/00222930600621601, http://zenodo.org/record/523243
Pycnoclavella tabella Kott 1990
No full textPycnoclavella tabella Kott, 1990 (Figure 8B) Pycnoclavella tabella Kott 1990a, p 77. Distribution Previously recorded (see Kott 1990a): South Australia (Spencer Gulf); Victoria (Portsea). New records: South Australia (Kangaroo I., 10–12 m, SAM E3292); Tasmania (Tasman Peninsula, 15–17 m, SAM E3291); Victoria (Portsea, SAM E3290). The species is usually in large aggregates on rocky walls and roofs of caves and overhanging ledges. This species has been recorded by scuba divers from relatively shallow waters. Description Specimens have the characteristic tangle of sandy, fragile, thin basal stolons, and narrow, often branching vertical stalks containing the long abdomina, also encased in thin, sandy test. On top of these vertical branches are the small spherical thoraces in thin, transparent, sand-free test, sometimes with a greenish oily appearance in life.Published as part of Kott, Patricia, 2006, Observations on non-didemnid ascidians from Australian waters (1), pp. 169-234 in Journal of Natural History 40 (3 - 4) on page 183, DOI: 10.1080/00222930600621601, http://zenodo.org/record/523243
Clavelina mirabilis Kott 1972
No full textClavelina mirabilis Kott, 1972 Clavelina mirabilis Kott, 1972: 165; 1990a: 50. Distribution. New records: Tasmania (Bicheno, Hairy Wall dive site east of Governor’s I., rock slope, 15–20 m, SAM E2845). Previously known from only two specimens off Waldegrave I., S.A. The new record suggests that the species has a wide range in the Southern Ocean, extending into the Great Australian Bight and up the eastern coast of Tasmania. Description. The newly recorded specimen has a common cylindrical stalk but the thoracic parts of the zooids are independent of one another each in a separate covering of clear transparent test. Thoracic muscle bands are arranged as recorded for the type, namely 8E, 8B, 2D.Published as part of KOTT, PATRICIA, 2003, New syntheses and new species in the Australian Ascidiacea, pp. 1611-1653 in Journal of Natural History 37 (13) on page 1616, DOI: 10.1080/00222930110104258, http://zenodo.org/record/526008
