Baie du Santal, Loyalty Islands, 120‒250 m depth, 21 mm. M . Radular tooth of specimen D. Scale bars = 10 mm, unless otherwise stated. Geographical distribution and bathymetry Queensland, Coral Sea and New Caledonia (Grand Passage area, Norfolk Ridge and Loyalty Islands ), from 100 to 700 m deep, typically at depths between 100 and 300 m . Remarks Shell moderately large to large (maximum shell length 121.6 mm ), narrowly conical to conical, with a low spire of concave outline and an angulate shoulder. Multispiral protoconch. Last whorl white to pale orange-brown, with occasional presence of rather diffuse broad spiral bands above and below midbody. Specimens with a nodulose last whorl ( Fig. 80I ) are known. Radular tooth ( Fig. 80M ) rather elongated, with the anterior and posterior sections subequal in length. Tooth serrated with 25 to 27 denticles arranged in one row, ending on a rounded cusp. Barb small. Blade rounded, almost indistinct, covering about 70% of the anterior section of the tooth. Strong basal spur present on top of the base. Conus ( S. ) queenslandis was considered a subspecies of Conus tribblei Walls, 1977 by R̂ckel et al. (1995b) based on similarities in conchological features. In the phylogeny ( Fig. 2 ), C. tribblei and C. queenslandis form two well-supported sister clades, at a distance consistent with a separation at the species level.
