Why was the species Oxybelis aeneus historically considered a single complex?
Answer
It lumped many distinct taxa together
The classification of the Brown Vine Snake, Oxybelis aeneus, was historically confusing because the name was used as a catch-all for various populations. Recent molecular and morphological studies revealed that what was considered a single, widespread species actually comprised numerous distinct, cryptic taxa, masking true biodiversity until taxonomic revisions were conducted.
