What primarily prompted the change in genus classification from *Leptotyphlops* to *Rena*?

Answer

Molecular and morphological data indicating necessary separation from Old World species

The reassignment of the Western Blind Snake from the genus *Leptotyphlops* to *Rena* resulted from modern phylogenetic analysis. Scientific scrutiny utilizing both molecular evidence (DNA analysis) and detailed morphological examinations revealed that the New World species grouped under *Leptotyphlops* were evolutionarily distinct enough to warrant separation into their own dedicated genus, *Rena*. This taxonomic revision aims to create a classification system that more accurately reflects the true evolutionary ancestry and relationships between these threadsnakes, especially when comparing them to Old World taxa.
