The Pringle 8188 specimen in W also bears a Winkler note but Rose separated it to his O. mexicana Rose. Choosing this specimen as lectotype would make plenty of isolectotypes, but a new name would become necessary in case that the Mexican and the Guatemalan specimens turn out to be different after all.
