I agree with
hcarlton, that it isn't
Pinguicula 'Weser'. It appears to simply be a very attractive form of
Pinguicula moranensis, which is a species that is quite variable in foliage and flower. Though the flower is very distinctive, perhaps someone has singled it out for mass propagation, and it could have an informal name it's known by. Your plant's flower seems quite well formed, with unique and distinctive patterns and markings, yet it may not have received distinct recognition, before now.
I'd check the standard images of registered
Pinguicula cultivars, first. Though I've recently looked through it, and didn't see one resembling your flower. Then I'd look through the
Pinguicula section of the
CP Photofinder, to see if there is a flower linked there that matches your flower. The foliage isn't very helpful, most cases, in identifying Mexican/equitorial Pinguicula, since so many have similar foliage, that varies greatly due to simple environmental differences. There are exceptions, however, especially for species that have distinctive foliage, such as
Pinguicula gypsicola,
Pinguicula medusina,
Pinguicula filifolia, or
Pinguicula moctezumae, among others.
Yes, the characteristics of the foliage, you describe for your plant, is very common, especially for forms of the species
Pinguicula moranensis, though it can be similar in other species, as well.
