Diagnosis
Comment	Higher Taxa: Wilcox et al. (2002) extablished a new family for Exiliboa and Ungaliophis, Ungaliophiidae, based on DNA sequence analysis. More recent authors (e.g. Pyron et al. 2013) grouped Exiliboa, Ungaliophis, Charina, and Lichanura into Ungaliophiinae which is basal to most other boids. Type species: Exiliboa placata BOGERT 1968 is the type species of the genus Exiliboa BOGERT 1968.
