The new species Mollugo viscosa Thulin & Harley is described from Minas Gerais in eastern Brazil. It was previously part of the recently published M. brasiliensis Thulin & Harley, a species that was found to be non-monophyletic in molecular phylogenetic analyses. Mollugo brasiliensis is here divided into a northern species (M. brasiliensis s.str.) in Bahia and a southern species (M. viscosa sp. nov.) in Minas Gerais. The new species differs from M. brasiliensis in its denser and more viscous indumentum, and in its distinctly smaller seeds with smaller tubercles and a smaller hilar peg, and from its sister species M. ulei by being a perennial herb with bisexual flowers.
