What term is used to describe the closely related species formerly grouped erroneously under P. obsoletus?
Answer
A species complex
The broad historical application of the name *Pantherophis obsoletus* grouped several evolutionarily distinct but related populations together under one taxonomic umbrella. Scientists now refer to this grouping as a 'species complex,' which is a collection of closely related species that were mistakenly consolidated into a single taxon based on superficial similarities or overlapping geography before detailed genetic studies were undertaken to differentiate them.
