Gargareans

They copulated with the Amazons annually in order to keep both tribes reproductive.

The Amazons kept the female children, raising them as warriors, and gave the males to the Gargareans.

[1] The ancient Greek geographer Strabo placed the Gargareans on the northern foothills of the Caucasus.

[2][3][4] According to E. Krupnov, the accuracy of the localization of Strabo's Gargareans in Galga-chuv (Ingushetia) is confirmed by archaeological, anthropological and ethnographic data.

[5] Gaius Plinius Secundus likewise localizes the Gargareans north of the Caucasus Mountains, but calls them Gegar.
