A monk who lived in the time of Kassapa Buddha.
After the Buddha's death, another monk, Adhammavādi, was charged with having violated the rules of the Vinaya, and Dhammavādi decided against him.
But Adhammavādi succeeded in getting two others to give a verdict in his favour.
These two monks were later born as Hemavata and Sātāgira. SNA.i.195f.
