In my state (New Mexico), Sceloporus undulatus used to be the common lizard everywhere, documented from every county. Of course, now we have 3 species (none of them undulatus) and in many places we just have to say it’s a Sceloporus sp. because they’re indistinguishable externally. I find these genomic studies with taxonomic implications frustrating as they seem to rarely clarify nomenclature. Yes, there indeed may be multiple species, formerly obscured under the name S. undulatus, but if the researcher is using specimens from a rather small number of scattered locations and they don’t have a handle on contact zones and extent of hybridization and introgression, the conclusions are, in my mind, suspect.
(Incidentally, S. consobrinus might not even be the proper oldest name for that species … might be S. thayerii. Just to add to the confusion.)
That’s my gripe for the day.
