Ungaliophiinae
Ungaliophiinae is a subfamily of booid snakes containing two genera, ''Ungaliophis'' (two species) and ''Exiliboa'' (one species). They are small constrictors that are found in Central and South America from southern Mexico to Colombia. They eat mostly lizards and frogs and are poorly studied. These snakes were formerly thought to be closely related to two other genera, ''Tropidophis'' and '' Trachyboa''; all four genera were united in the family (Tropidophiidae) based on the presence of a tracheal lung and the absence of a left lung. However, ''Ungaliophis'' and ''Exiliboa'' are now known to be more closely related to booid snakes, whereas ''Tropidophis'' and ''Trachyboa'' are known to be more closely related to the American red pipesnake ''Anilius''. Within Booidea, ''Ungaliophis'' and ''Exiliboa'' are thought to be most closely related to North American ''Charina'' and ''Lichanura ''Lichanura'', the rosy boas, are a genus of snakes in the family Boidae.

Tropidophiidae
The Tropidophiidae, common name dwarf boas or thunder snakes, are a family of nonvenomous snakes found from Mexico and the West Indies south to southeastern Brazil. These are small to medium-sized fossorial snakes, some with beautiful and striking color patterns. Currently, two living genera, containing 34 species, are recognized. Two other genera ('' Ungaliophis'' and ''Exiliboa'') were once considered to be tropidophiids but are now known to be more closely related to boids, and are classified in the subfamily Ungaliophiinae. There are a relatively large number of fossil snakes that have been described as tropidophiids (because their vertebrae are easy to identify), but which of these are more closely related to ''Tropidophis'' and ''Trachyboa'' and which are more closely related to ''Ungaliophis'' and ''Exiliboa'' is unknown. Description This family is confined to the neotropics, mainly in Hispaniola, Jamaica, and the Cayman Islands, with the greatest diversity being in ...

Genera
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...

Booidea
The Booidea, also known as booid snakes, are a superfamily of snakes that contains boas (family Boidae) and other closely related boa-like snakes (but not pythons, which are in a separate superfamily called Pythonoidea). As of 2017, Booidea contains 61 species, including the eponymous neotropical ''Boa constrictor'', anacondas (genus ''Eunectes''), and smaller tree and rainbow boas ('' Corallus'', '' Epicrates'', and ''Chilabothrus'') as well as several genera of booid snakes from various locations around the world: bevel-nosed boas or keel-scaled boas (''Candoia'') from New Guinea and Melanesia, Old World sand boas (''Eryx'') from Northeast Africa, the Middle East, and Southwest Asia, rubber boas (''Charina'') and rosy boas (''Lichanura'') from North America, neotropical dwarf boas ('' Ungaliophis'') and the Oaxacan dwarf boa (''Exiliboa'') from Central America, Madagascan boas or Malagasy boas (''Acrantophis'' and ''Sanzinia'') from Madagascar, and the Calabar python (''Calabaria ...
