Glanapteryginae [SEP] parent taxon
Glanapteryginae
The Glanapteryginae are a subfamily of catfishes (order Siluriformes) of the family Trichomycteridae. It includes four genera, "Glanapteryx", "Listrura", "Pygidianops", and "Typhlobelus".
Phylogeny.
Monophyly of the subfamily is supported by five synapomorphies involving reductions in the fins, caudal skeleton, and laterosensory system. It has been proposed that the sister group to this subfamily is the Sarcoglanidinae. "Listrura" is the sister group to the remainder of the subfamily. "Glanapteryx" is sister
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
