Annulipalpia [SEP] parent taxon
Annulipalpia
The Annulipalpia, also known as the "fixed-retreat makers", are a suborder of Trichoptera, the caddisflies. The name of the suborder refers to the flexible terminal segment of the adult maxillary palps, which often has many tiny rings.
The larvae construct fixed retreats in freshwater aquatic environments in which they remain stationary, waiting for food to come to them. Members of the Psychomyiidae, Ecnomidae and Xiphocentronidae families construct simple tubes of sand and other particles held together by silk and anchored to the bottom,
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
