Glossodoris
Glossodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae.
Taxonomic history.
The use of the genus name "Glossodoris" has been a subject of debate amongst taxonomists for over 150 years. Because it is the oldest name in the Chromodorididae it has been used differently by different taxonomists, sometimes including many species of "Hypselodoris" and "Chromodoris" and the other smaller genera recognised today. Its modern status is based on the analysis of DNA sequences
Taxon in disguise
In bacteriology, a taxon in disguise is a species, genus or higher unit of biological classification whose evolutionary history reveals has evolved from another unit of similar or lower rank, making the parent unit paraphyletic. This happens when rapid evolution makes a new species appear radically different from the ancestral group, so that it is not (initially) recognised as belonging to the parent phylogenetic group, leaving the latter an evolutionary grade.
While the term is from bacteriology, parallel examples are found throughout the tree of
