What is "sophagasenus"

Sophagasenos also spelt Sophagasenus or Sophagasenas ( Sanskrit: Subhagasena) was a local Indian king ruling in Kabul and Kapisa valley ( Paropamisade of the classical writings) during the last decade of 3rd century BCE. Sophagasenus finds reference only in "The Histories" of Polybius. The identity of Sophagasenus is not clear. Many historians believe that Sophagasenus was a princely scion of the Mauryas of Magadha but others believe him to have been a non-Mauryan local ruler from the area he ruled i.e. from Kabul/ Kapisa land. Some writers relate him to the Jatt lineage while others claim him from Yadava or Yadu line, but for no valid reason.
