Since the 2011 local government reform it is part of the municipality Erymanthos, of which it is a municipal unit. The municipal unit has an area of 71.586 km2.

Its population in 2011 was 246 for the village, 284 for the community and 380 for the municipal unit.
The municipal unit Leontio is subdivided into the following communities (constituent villages in brackets):
- Ano Mazaraki
- Leontio (Leontio, Vetaiika, Golemi, Thomaiika, Katsaitaiika, Kounavaiika, Ovryokambos)
Evidence suggests that the Achaeans settled Leontio after the Trojan Wars, at this time it was a Polis. This is supported by archeological excavations in the area by the archaeologist N. Kiparisis during the period 1931-32. Mycenean tombs from the 14th-12th century BC were found. The different artifacts excavated in a number of ancient cemeteries confirmed the Polis flourished at about 1,000 BC. Though older findings date it back to 3,000-2,000 BC. The acropolis dates back to around the 3rd century BC.
It was located on the ancient border of Achaea and Arcadia near Vlasia where excavations uncovered a Mycenean tomb and an ancient theater from the 4th century BC. The temple of Artemis was located along the ancient road which led to Arcadia. Its length was 35 m and its width was 11 m.
