"Lichanura" is an outdated genus name previously used for some boa species, now mostly included within the Charina genus. Historically, it represented certain lineages of rubber boas and rosy boas native to western North America ๐. Think of it like a scientific rebrand. Modern taxonomic revisions led to a change, consolidating these species under Charina. This happens as scientists refine their understanding of evolutionary relationships. Today, you're less likely to encounter "lichanura" in current scientific literature. It's more of a historical reference.
