ABSTRACT
In this paper we redescribe the type species of Mago O. Pickard-Cambridge, M. intentus O. Pickard-Cambridge, and describe Mago brimodes Ruiz Maddison sp. nov. from Ecuador. Based on both morphological features and the 16SND1 gene region, we concluded that the larger spiders traditionally identified as Mago, such as Mago acutidens Simon and related species, are not closely related to the small dark M. intentus (type species) and M. brimodes. Matinta Ruiz Maddison gen. nov. is therefore proposed to hold most species previously included in Mago. The following species are transferred from Mago to the new genus: Matinta acutidens (Simon, 1900) comb. nov. (type species), Matinta apophysis (Costa Ruiz, 2017) comb. nov., Matinta balbina (Patello Ruiz, 2014) comb. nov., Matinta chickeringi (Caporiacco, 1954) comb. nov., Matinta delicata (Patello Ruiz, 2014) comb. nov., Matinta fasciata (Mello-Leitão, 1940) comb. nov., Matinta fonsecai (Soares Camargo, 1948) comb. nov., Matinta furcata (Costa Ruiz, 2017) comb. nov., Matinta jurutiensis (Patello Ruiz, 2014) comb. nov., Matinta longidens (Simon, 1900) comb. nov., Matinta mimica (Costa Ruiz, 2017) comb. nov., Matinta opiparis (Simon, 1900) comb. nov., Matinta pardo (Costa Ruiz, 2017) comb. nov., Matinta procax (Simon, 1900) comb. nov., Matinta saperda (Simon, 1900) comb. nov., Matinta silvae (Crane, 1943) comb. nov., Matinta similis (Patello Ruiz, 2014) comb. nov., Matinta steindachneri (Taczanowski, 1878) comb. nov. and Matinta vicana (Simon, 1900) comb. nov. Mago dentichelis Crane, 1949 is transferred to Noegus Simon.
