Synonyms[1] | |

Azumamorula mutica, common name the smooth ricinula, is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.[1] It is the only species in genus Azumamorula.
Description
The shell size varies between 15 mm and 20 mm
Distribution
This species is distributed in the Indian Ocean along Madagascar , the Mascarene basin, Réunion, and along Eastern Australia.
Taxonomy
This species was originally named Ricinula mutica by Lamarck in 1816,[2] grouping it with species that are now mostly in Drupa and Morula.[lower-alpha 1] In 1823, Dall defined two new genera, Drupina and Morulina, to hold species of Drupa and Morula having simple non-plaited columnellae. He chose R. mutica as the type species for Morulina.[lower-alpha 2][3]
Thiele in 1931 and Wenz in 1941 had placed Morulina into Drupa. In 1968, Emerson found that the teeth on the radula of D. mutica had an unusual shape. As a result, he desired to split it out to its own genus, but the name Morulina was already taken as a genus of arthropod. Thus he introduced a new name Azumamorula, recognising Masao Azuma who had extracted the radula specimen.[4]
In 2004, Houart placed Azumamorula and Oppomorus as subgenera of Morula, and moved Morula from subfamily Rapaninae to Ergalataxinae.[5][6] However, in 2013, a phylogenetic study of the sequences for four genes indicated that Morula (Morula) sensu stricto was polyphyletic, and Morula (Oppomorus) was a separate clade.[7] The relevant genes from A. mutica haven't been sequenced, but it's unlikely to be part of a more-restricted Morula–Habromorula group. As of 2020, Houart lists Azumamorula as a separate genus[8] and Molluscabase classes the combination Azumamorula mutica as "accepted".[9]
