Apis of Sicyon

Apis was the son and heir of King Telchis, descendant of the city's founder Aegialeus. He was the father of Thelxion who succeeded him in the throne. Apis belonged to a legacy of primeval kings of Sicyon which is as follows: Aegialeus – Europs – Telchis – Apis – Thelxion – Agyreus – Thurimachus – Leucippus. Mythology 
Apis reached such a height of power before Pelops came to Olympia that all the territory south of the Isthmus was called after him Apia. This was also attributed to his Argive namesake who have had Peloponnesus named Apia after him. Notes
