Emesinae [SEP] parent taxon
Emesinae
The Emesinae, or thread-legged bugs, are a subfamily of the Reduviidae (i.e., assassin bugs). They are conspicuously different from the other reduviids by their very slender body form. They are stalking, predatory insects that can be collected on palm fronds, cliffs, spider webbing, or near lights at night (many can be collected by blacklight). They walk on their mid and hind legs; the front pair is raptorial. Some groups specialize on spiders. Very little is known about emesines except
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
