The Year 158 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Lepidus and Laenas (or, less frequently, year 596 Ab urbe condita) and the Sixth Year of Houyuan. The denomination 158 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Demetrius I then replaces him with Orophernes Nicephorus, a supposed son of the late king, Ariarathes IV. With Ariarathes V deprived of his kingdom, he flees to Rome.
