Ocypode [SEP] parent taxon
, using the type species "Cancer ceratophthalmus" described by the German naturalist Peter Simon Pallas in 1772.
"Ocypode" was previously the only genus classified under the ghost crab subfamily Ocypodinae until 2013, when Katsushi Sakai and Michael Türkay reclassified the gulf ghost crab into a separate genus, "Hoplocypode". It belongs to the family Ocypodidae. Ghost crabs of the genus "Hoplocypode" can be distinguished from those in "Ocypode" by examining their gonopods. In the former, the first gonopod has a complex hoof-
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
