Genetic data collected in 2011 pointed to there being only three extant species: ''A. scrobiculatus'', ''N. macromphalus'', and ''N. pompilius'', with ''N. belauensis'' and ''N. stenomphalus'' both subsumed under ''N. pompilius'', possibly as [[subspecies]],<ref name="Dunstan et al. 2011" /> though this was prior to the description of three additional species (''samoaensis'', ''vanuatuensis'' and ''vitiensis'').
