Australian Museum P21732, North West Cape, Western Austtralia, near Garden Island, coll. L Marsh.</p><p>Remarks. The series of A. nigrescens comprises 69 specimens collected from the Taharoa Ironsands Terminal, North Island, New Zealand. Taharoa Ironsands Terminal is an export port for iron sands extracted from coastal sand dunes in Taharoa, south of Kawhia Harbour. The sand is piped to a mooring situated in approximately 30 m of water almost 3 km from shore (38°10’32”S, 174°41’21”E) (Figure 1). The specimens were collected from 27 sites, attached to the mooring and anchor lines, at 0–7 m depth. The specimens range from 4.5 mm to 68.3 mm basal diameter and 2.5 mm to 70.0 mm rostral height (Figure 2A–E), and accord well with published descriptions (Pope 1945; Jones 1990). The Taharoa specimens are from an established population: at least three generations are present and four individuals were ovigerous. This species was most likely introduced via shipping at Taharoa.</p><p>Austromegabalanus nigrescens is native to open rocky shores of southern Australia, ranging from North West Cape (~ 21°47’S) in Western Australia (this study), to Southern Tasmania (~43° S) (Jones, 1990; Jones et al. 1990), and is a known biofouler, having been recorded from Copenhagen on vessel hulls (Krüger 1927) and possibly the Ivory Coast (Gruvel 1903). The endemic Notomegabalanus decorus (Darwin, 1854), is also present, but relatively uncommon, at Taharoa terminal. The range of A. nigrescens within New Zealand is currently unknown but based on New Zealand’s latitudinal range, could be expected to include most of the New Zealand coastline. Notomegabalanus decorus and A. nigrescens occupy a similar habitat and encrusted individuals of the two species could be mistaken for each other by the casual observer.</p></div>	https://treatment.plazi.org/id/FC5B87B2FFB4FFD2FF007CD7A141F8B4	Public Domain	No known copyright restrictions apply.

The present specimens of A. psittacus represent not only the first record of the species from New Zealand, but also the first extralimital record of the species.</p><p>Austromegabalanus psittacus is the largest known sessile barnacle, attaining a height of 20 cm and width of 8 cm, and ranges along much of the Pacific coast of South America, ranging from Peru to Chile and to Patagonia in the Atlantic (Young 2000). Within its natural range, A. psittacus inhabits a wide range of substrates, from the shore to at least 20 m. In Chile, A. psittacus is a culinary delicacy and in 1996, over 870 tonnes were commercially harvested (FAO 2006).</p><p>The material of A. psittacus from Port Wellington comprises a single cluster of nine individuals, the largest with a maximum height of 53.9 mm and a maximum carino-rostral diameter of 18.6 mm (Figure 2 F–J). The Port Wellington specimens of A. psittacus agree well with Chilean material (NIWA 25444), differing in having proportionally longer and more slender tergal apices. The differences in the tergal apices are probably attributable to wear and damage—the Port Wellington specimens were growing on a level subtidal substrate without intense wave action, in contrast to the Chilean specimens from intertidal rocks on an open coast. The similar size of most Port Wellington A. psittacus suggests that they recruited at a similar time, perhaps even via a single reproductive event from a source population attached to a vessel hull.</p></div>	https://treatment.plazi.org/id/FC5B87B2FFB4FFD0FF007B26A14DFD45	Public Domain	No known copyright restrictions apply.
