It is, furthermore, not clear that all the populations referable to the group are yet known. Three of the five species, menta, ruizi, and lamari, have only recently been discovered, and no contact zones are known. The closest approach is that of menta and solitarius, which are less than 30 km apart in the west and north respectively of the Sierra de Santa Marta.
