Diagnosis. Amycines genera are in need of revision under phylogenetic standards, but some comparisons can be given. According to Galiano’s (1968) key for amycine genera, the genus is similar to Hypaeus Simon by having only small teeth, although multiple, on the chelicerae, and the ocular area being wider in the front, among other characters. From Hypaeus , species of Mago would differ by having the male clypeus lower or equal to the height of the radio of AME ( Galiano, 1968), but we think that this character should be reevaluated after other species are described in both genera. At least for most species, a light abdomen with a dorsal pair of dark longitudinal stripes (leaving a yellowish T-shaped median marking), each bearing two light crescents, also helps diagnose the genus ( Figs 1, 3 ).

Note. Based on the pairings available at the time, Galiano (1968) mentioned in her key that females of both Mago and Hypaeus would have a single median opening on the epigynal plate. This is not true, since the species of Mago presented here, for instance, have a pair of openings.
