Editing Boidae (section)

==Taxonomy==
[[Pythonidae|Python]]s were historically classified as a subfamily of Boidae (called Pythoninae), but it was later determined that they are not closely related to boas despite having superficial similarities.<ref name="Reynolds14">{{cite journal|last1=Reynolds|first1=RG|last2=Niemiller|first2=ML|last3=Revell|first3=LJ|title=Toward a Tree-of-Life for the boas and pythons: multilocus species-level phylogeny with unprecedented taxon sampling|journal=Molecular Phylogenetics and Evolution|date=2014|volume=71|pages=201–213|url=http://www.rgrahamreynolds.info/wp-content/uploads/2014/01/Reynolds_etal_2014_MPE.pdf|doi=10.1016/j.ympev.2013.11.011|access-date=2018-05-14|archive-url=https://web.archive.org/web/20151202212953/http://www.rgrahamreynolds.info/wp-content/uploads/2014/01/Reynolds_etal_2014_MPE.pdf|archive-date=2015-12-02|url-status=dead|pmid=24315866}}</ref>

Almost all of the [[Boinae|non-boine]] boids are frequently elevated to their own full families: Calabariidae/inae, Candoiidae/inae, Charinidae/inae, Erycidae/inae, Sanziniidae/inae, and Ungaliophiidae/inae.<ref name="Reynolds14"/> The taxonomy of boid snakes has been long debated, and ultimately the decision whether to assign a particular clade to a particular [[Linnaean taxonomy|Linnaean rank]] (such as a [[Superfamily (zoology)|superfamily]], [[Family (biology)|family]], or [[subfamily]]) is arbitrary.

The subfamily Ungaliophiinae was formerly made up of four genera. Two of them (''[[Tropidophis]]'' and ''[[Trachyboa]]'') are actually more closely related to the American pipe snake (''[[Anilius|Anilius scytale]]'') than to the boas, and are now placed in the family [[Tropidophiidae]] within the superfamily [[Amerophidia]]. The other two genera (''[[Ungaliophis]]'' and ''[[Exiliboa]]'') are the sister group of the ''[[Charina]]''/''[[Lichanura]]'' clade within Boidae.<ref name="Reynolds14"/><ref name="Pyronetal2014">{{cite journal|last1=Pyron|first1=R.
