Challenger Plateau: NIWA 33141 , 1 female (tcl 12.8 mm), 37°45.36’S, 168°12.88’E, 702– 700 m, TAN0707/38, 29 May 2007 ; NIWA 33175 , 4 damaged specimens, 37°52.62’S, 168°18.70’E, 648–652 m, TAN0707/85, 3.

VI.2007; NIWA 42685 , 1 female (tcl 13.1 mm), 39°32.61’S, 169°42.87’E, 636– 634 m, TAN0707/93, 4. VI.2007.

Remarks. The present series of A. australis represents the first record of the genus and species from New Zealand, agreeing well with published accounts ( Hanamura 1989; Hayashi 2004). The rostrum is usually spiniform as reported by Hanamura (1989) for the type material, and occasionally triangular. Poore (2004) and Poore et al. (2008) reported A. australis from 32–680 m, so the capture depth of the New Zealand specimens (552–797 m) extends the known bathymetric range. The occurrence of A. australis from both the west and east coasts suggests that the species has a wide distribution in New Zealand waters.

Distribution. Southern Australia and now from New Zealand waters; 32– 797 m.
