Another Interesting Example

[Kondla, Norbert FOR:EX]

Apologies for any inadvertant creation of cranial cramps but before I forget
this example: Speyeria cybele/leto. A 1940's list lumped these into one
species without presenting any data or rationale. A 1990 list of Utah
butterflies available on the web splits these into two species without
presenting any data or rationale.  In the absence of data or published
rationale's my sense of promoting stability in this case would be to go back
to the original usage of the authors who described cybele and leto as
distinct species (at least I think that is the way it happened with no
literature here at the office to refer to). Just my opinion, form your own
based on available information and preferred concepts of species/subspecies
:-)
