Two species of scyphozoan jellyfish were observed to be used as live baits in a traditional small-scale trap fishery operated in the eastern Sri Lanka. However, there was limited taxonomic knowledge on the respective scyphomedusae. Therefore, altogether 83 specimens of these jellyfishes netted from several coastal localities of the country from 2016 to 2020 and eight museum specimens were examined taxonomically to reveal their identity. Of the species identified, Acromitus flagellatus was reported for the first time from Sri Lanka while Lychnorhiza malayensis was re-reported and these two species are presented here with detailed descriptions. As both species are mild stingers, so far no severe health issues have been reported in Sri Lanka. However, as bloom-forming species clogged jellyfish have adversely affected gillnet, trammel-net, and stake-net operations in coastal water bodies of Sri Lanka by reducing fish catches and damaging nets.
