Oryctodiplax [SEP] parent taxon
Oryctodiplax
Oryctodiplax is an extinct genus of dragonfly in the family Libellulidae.
Fossils (mainly larvae) of these dragonflies have been found in the Miocene of Italy (age range: from 7.246 to 5.332 million years ago).
The type species is "Oryctodiplax gypsorum". It was a species resistant to a highly saline environment, formed in the Mediterranean salinity crisis, occurred during the latest stage of the Miocene, with the isolation of the Mediterranean sea and its subsequent drying.

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
