What is "antialcidas"

Antialcidas Nikephoros ( Greek: ; epithet means "the Victorious") was a Greek King of the Indo-Greek Kingdom, king of the Eucratid Dynasty, who reigned from his capital at Taxila. Bopearachchi has suggested that he ruled from ca. 115 to 95 BCE in the western parts of the Indo-Greek realms, whereas R. C. Senior places him around 130 to 120 BCE and also in eastern Punjab (which seems better supported by coin findings). Senior does however believe that he ruled in tandem with King Lysias.
