Anarithma inornata is a species of sea snail, a marine gastropod mollusk in the family Mitromorphidae.

Description The shell is more globose and thicker than in Columbella stepheni (synonym of Anarithma metula (Hinds, 1843) )of which it was originally considered a variety. The brown spots are smaller and are better rounded on the upper whorls. On the body whorl, they form a second series located near the base. Notably, the large triangular brown spot does not appear in this species. Hervier, J. "Le genre Columbella dans l’Archipel de la Nouvelle-Calédonie." Journal de Conchyliologie 46 (1899): 305–391

Distribution This marine species occurs off the Loyalty Islands.
