Mahavansa/Chapter 33 tells....When Lanjatissa (119-109 BC) was dead his younger brother named Khallata Naga (109-104 BC) reigned six years.
Mahavansa/Chapter 33 tells....A commander of troops named Kammaharattaka, overpowered the ruler, king Khallata Naga, in the capital itself. But the king's younger brother named Vatta Gamini (104 BC) killed the villainous commander and took on himself the government. The little son of his brother, king Khallatanaga, whose name was Mahaculika, he took as his son; and the (child's) mother, Anulädevi, he made his queen. Since he had thus taken the place of a father they called him Pitiraja.
