The Neotropical subgenus Notalina (Neonotalina) Holzenthal, 1986 has ten described species in two species groups: brasiliana, formed by seven species from Southeastern Brazilian and Goiás State; and roraima, represented by three species from the Amazonian and Andes regions. In this paper, a new species of Notalina is described and illustrated from specimens collected in the Mantiqueira mountain range, Southeastern Brazil. The new species belongs to the brasiliana group and is easily recognized by the poorly developed dorsomesal and ventrolateral processes and the pair of mound-like protuberances located mesolaterally on abdominal segment X, and by the robust, rounded mesoventral processes and long digitate mesodorsal processes of the inferior appendages. A key to the Neotropical species in the genus is provided.
