Lowry & S.J. Keable, Flying Scud [TAS-279]. Paratypes: 59 specimens, 7.5–12.4 mm, AM P.69451; 1 male, 12.1 mm, AM P.69453; 1 male, 9.2 mm, AM P.69454, same collection details as holotype.
Type locality. North side of Cape Sorell, about 400 m outside Hannants Bight on a line toward large bluff of Ocean Beach, Tasmania, Australia (42°11.4’S 145°11.08'E), 30 m depth.
Etymology. Named for the Macquarie Harbour pilot boat that put out on 23 July 1830 to guide the Government brig Tamar through the difficult harbour entrance known as 'Hells Gates'. When about half-way to the brig conditions deteriorated into a south-westerly gale and the pilot boat, with its nine crew, disappeared.
