According to an article published in 1973 [1], the fig wasps that pollinate Ficus fistulosa was Ceratosolen hewitti. This led me to deduce that the wasp I saw on the figs found on this tree was Ceratosolen hewitti. But, someone by the initial Jeong wrote to me on 11 May 2020 to clarify that this wasp is actually a Philotrypesis species.
