Which former binomial nomenclature is still used in older field guides for this snake?
Answer
*Leptotyphlops humilis*
The classification of this small snake has undergone revisions, a common occurrence in herpetology reflecting updated scientific understanding of evolutionary relationships. Because these changes take time to filter through all levels of documentation, many older field guides or local historical literature still refer to the Western Blind Snake by its former scientific designation. This previous classification, which scientists once used, is *Leptotyphlops humilis*, although the current accepted designation is *Rena humilis*.
