The Mahāvaṃsa Ṭīkā (p.176) says that Dhammarucika was the name given to the monks of Abhayagiri when they seceded from the Mahāvihāra, and gives elsewhere (p.676 f) the points on which they differed from the Theravādins.

They again became powerful in the time of Mahāsena, through the influence of Saṅghamitta, and almost succeeded in destroying the Mahāvihāra.

2. Dhammaruci Thera.– An Arahant. In the time of Dipaṅkara Buddha he was a young man named Megha, and on hearing the Buddha’s declaration regarding Sumedha, he entered the Order under the latter. However, owing to wrong association, he left the Order and murdered his mother. For this he suffered in Avīci and was later born as a fish. One day he heard some shipwrecked sailors calling on the name of Gotama Buddha for protection, and, remembering Dipaṅkara’s prophecy, the fish died. He was then born in Sāvatthi, and hearing the Buddha teach at Jetavana, he entered the Order and became an Arahant. Ap.ii.429 f.
