Type material. Holotype: ♁ from Matinha, Nossa Senhora do Perpétuo Socorro, Itacoatiara, Amazonas, Brazil (3.154⁰S 59.324⁰W), 07.XI.2003, F.N.A.A. Rego et al. leg. (IBSP 98226).

Etymology. The species is named after the folkloric Matinta Pereira (or Matinta Perera), the Amazonian famous witch.

Diagnosis. The male of M. pereirae is similar to those of the species within the vicana species-group, especially those of M. silvae, M. fonsecai and M. vicana for having no mastidia, a bump on the retrolateral, proximal portion of palpal tibia, and the prolateral portion of tegulum (embolus base) strongly asymmetrical proximally when compared to retrolateral portion. It can be distinguished from those of M. fonsecai and M. silvae for not having a bifid embolus tip, and from M. vicana for having the embolus tip stouter (Figs 34, 45).
