The roving group was called the Incas and was led by Zaphod. Since there were no females in the group, the Incas were not considered an actual mob. Meerkat mobs need a dominant female in order to be a functional breeding group. The Incas were simply a coalition of roving males looking for better mating opportunities. The Incas did not last long and soon came across another group made up of mostly females and juveniles.
