Kayserops [SEP] parent taxon
Kayserops
Kayserops is a trilobite in the order Phacopida (family Acastidae), that existed during the lower Devonian in what is now Germany. It was described by Delo in 1935, and the type species is "Kayserops kochi", which was originally described under the genus "Cryphaeus" by Kayser in 1883. The generic name is derived from the name of the species' author. The type locality was the Rhenish Massif.

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
