Demeterops [SEP] parent taxon
Demeterops
Demeterops is a genus of trilobites in the order Phacopida, that existed during the lower Ordovician in what is now the United States. It was described by Pribyl and Vanek in 1985, and the type species is "Demeterops loella", which was originally described as a dubious species in the genus "Pilekia" by Demeter, in 1973. The new generic name honours the species' original author. The type locality was the Fillmore Formation in Utah.

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
