Definition
The genus Lichanura is a former classification for certain boa species, now primarily categorized under the genus Charina 🐍. This genus once included rosy boas and sometimes rubber boas, found in western North America. Think of it as a prior edition of a science textbook. As scientific understanding evolved, the classifications were revised. You'll primarily encounter this term in older literature or historical references. The change reflects a refinement in understanding evolutionary relationships.
