A class of deva, among whom virtuous men, such as those that maintain their parents and engage in harmless trades, are born (SN.vs.404).
From the Commentary (SNA. p.379) it would appear that Sayampabhā is probably a generic name for all devā (ye te attano ābhāya andhakāraṃ vidhamitvā ālokakaranena Sayampabhāti laddhanāmā cha kāmāvacaradevā).
