This report documents the first record of the genera Eucheilota and Mitrocomella and species Porpitaporpita and Physaliaphysalis in Bali, Indonesia, based on observed occurrences in different times and sites. The coincidence of the annual stranding of Physaliaphysalis in the east Bali and south Java coasts during the monsoon periods in Indonesia suggests a link with the upwelling events in the areas. However, more work is needed to analyse this phenomenon and study the occurrences of other Hydromedusae due to the limited data on hydrozoans in Indonesian waters. Overall, this report provides primary data to contribute to the general understanding of the biodiversity of marine organisms in Indonesia.
