Mammillaria linaresensis R & F Wolf, Kakteen und andere Sukkulenten 41(11):262 (1990)
Reported from Mexico, Nuevo Leon.
This species was provisionally accepted in the "New Cactus Lexicon (2006), with the note that althought it was first "thought to be a variant of M.melanocentra, it perhaps has more of M.gigantea about it". Subsequently in the recent CCC 2016 David Hunt has endorsed this finding and recognized it separately from M.melanocentra as a species, although still "provisionally".
