Original Description of Canarium rapanuense by Liverani, Wieneke & Kronenberg, 2021, p. 63:

• "Shell average size 18-28 mm, lightweight, ovatebulbous shape, short spire of 6 whorls smooth except juvenile whorls bearing tiny nodules, without juvenile varices, subsutural cord visible only in early whorls; protoconch eroded in all specimens examined, but apparently of 2.5-3 whorls, 0.5-0.6 mm in diameter; anterior canal longer that in typical C. maculatum, lip barely thickened with thin border, stromboid notch shallow with flaring lobe between stromboid notch and anterior canal; aperture white, adcolumellar side of outer lip with fine lirae, columella smooth with few lirae near posterior canal and few small teeth near anterior canal; last whorl coloured white with two large spiral bands of light orange-brown, often with numerous irregular axial brown streaks. Operculum typically strombid, hardly arched, with 5-6 serrations, distal end often damaged. Animal colour unknown to us."
