L1073, tesopacensis or wagneriana?

Hi guys, I'm making some studies about  all the species of mammillaria and a little order with all the plants I have in my greenhouse, because I've always been so messy with my job and I was growing a jungle. There' a specimen with a field number, L1073, that I received as a gift four-five years ago from an italian big mammillaria grower. It was marked by him as Mammillaria tesopacensis var. papasquiarensis, but if I look in the Mammillaria book of pilbeam, the FN refers to M. wagneriana. On the internet, in the cactus field number query, it's written that the identification is not sure. Has anyone a plant with this FN who has an opinion about?
