Ischiochaetus [SEP] parent taxon
Ischiochaetus
Ischiochaetus is a genus of flies in the family Dolichopodidae, found in New Zealand. The genus was originally named by Octave Parent in 1933. However, as the genus was not designated a type species, this name was unavailable until 1989, when Daniel J. Bickel and C. E. Dyte designated "Ischiochaetus ornatipes" as the type species.

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
