Although some authors have expressed doubts, the nominal species Strombus maculatus G. B. SOWERBY II, 1842 is generally considered to have an extensive very wide distribution range in the Pacific, stretched from the Hawaiian chain in the north and Palau in the west to Rapa Nui, also known as Easter Island or Isla de Pasqua, in the southeast. Based on morphologic and morphometric analyses, three distinct morphospecies can be distinguished. Strombus floridus var. depauperata DAUTZENBERG & BOUGE, 1933 is recognized as a distinct species, here recombined to Canarium depauperatum, and Canarium rapanuense is described as a species new to science. The distribution of Canarium maculatum is restricted to the Hawaiian chain.
