Rishikas in Saka-dvipa
The name Rishika ans well as Parama Rishika occurs in Mahabharata as a part of Saka-dvipa.
These northern Rishikas have been addressed as Uttara Rishikas (i.e. Rishikan.uttaranapi) and Parama Rishikas and are shown to be very close neighbors of the northern division of the Kambojas i.e. the Parama-Kambojas and the Lohans.
Per Mahabharata evidence, the allied tribes of the Lohans, Parama-Kambojas, northern Rishikas and Parama Rishikas had fought a fierce war with the forces of Pandava Arjuna during latter's Digvijay expedition against the tribes of Uttarapatha or northern division.
The Kishikindha Kanda of Valmiki Ramayana also refers to these northern Rishikas and locates them in Saka-dvipa, in the neighborhood of the Sakas, Kambojas, Yavanas, Bahlikas, Tanganas, Chinas, Parama-Chinas etc. of the Central Asia.
