Morula is a genus of small, predatory sea snails, marine gastropod mollusks in the subfalily Ergalataxinae of the family Muricidae, the murex snails or rock snails. [1]

Taxonomy

In 2002, Roland Houart described two new species and revised eight others, for a total 23 species of Morulasensu stricto. [52] He had previously (1994–1995) described Habromorula as a separate genus, containing 14 species that were earlier classified with Spinidrupa sensu lato. [53] In 2004, he placed Azumamorula , Oppomorus , and Habromorula into Morula as subgenera, and moved the whole group from subfamily Rapaninae to Ergalataxinae. [54]

Molecular genetics

In 2012–2013, Claremont et al. published a study of sequences for four genes across numerous species of Morula and related molluscs. [55] They found a clade of 11 species, and proposed a restricted definition of Morula to include: M. aspera, M. benedicta, M. (Habromorula) biconica, M. chrysostoma, M. (H.) coronata, M. (H.) japonica, M. nodicostata, M. (H.) spinosa, M. (H.) striata,M. uva (type species), and M. zebrina.

Habromorula did not form a clade in this analysis, however the authors noted that "monophyly of this morphologically distinctive group is not strongly contradicted, so that further sampling and analysis could yet support Habromorula as a monophyletic subgenus of Morula".

Subgenus Morula (Oppomorus) formed a separate clade; the authors proposed returning Oppomorus to genus level, containing O. nodulifera, O. funiculata and O. purpureocincta.

M. ceylonica, M. granulata, M. marginalba, M. musiva, and an undescribed species formed a distinct clade related to Muricodrupa. The authors proposed resurrecting the genus name Tenguella , for which T. granulata is the type species. They note that these species "have not previously been recognized as a morphologically distinctive group".

"Morula" anaxares was weakly related to Muricodrupa fenestrata, and "Morula" nodulosa was sister to the Tenguella–Muricodrupa group. "Morula" parva and "Morula" echinata placed in a third major clade, separate from the two that contain Tenguella and the main Morula group, respectively.

In response to the gene-sequence phylogeny, Houart, Zuccon and Puillandre formally described new genera in 2019: Claremontiella , Murichorda , and Lauta . [56] C. nodulosa, C. consanguinea, Mur. rumphiusi, and L. parva were previously in Morula. They also moved Morula anaxares to Muricodrupa anaxares , and reassigned M. palmeri to Pascula , the latter on basis of morphology rather than gene sequence.
