You can call them "Segmentary Societies" like Emile Durkheim, "Regulated Anarchies" like Max Weber, "Peaceful Societies" like on the Website mentioned below or "Matriarchy", like German Scholars define it (not to confuse with Bachofen, goddess movement or FemDom). It all is the same kind of society with the same patterns.

• No violence
• Sexual freedom including all ages
• Decision making by consensus
• Living in clans and/or tribal communities
• Veneration of the ancestors
• Close integration/interaction with nature

"Peaceful societies are contemporary groups of people who effectively foster interpersonal harmony and who rarely permit violence or warfare to interfere with their lives. This website serves to introduce these societies to students, peace activists, scholars and citizens who are interested in the conditions that promote peacefulness. It includes information on the beliefs of these peoples, the ways they maintain their nonviolence, and the factors that challenge their lifestyles."
