The mutualism between the fig tree and the fig wasp pollinator is an important keystone interaction for tropical forests. However, many antagonistic and parasitic species take advantage of the fig/fig wasp mutualism. One such parasite is the gall midge that develops inside fig syconia. Gall midges in fig syconia have sporadically been seen around the world, but until now they have never been observed in Panama. In this study a new Panamanian gall midge in fig syconia is described, together with a supposed parasitoid of the gall midge. The study furthermore investigates the gall midge effect on reproductive success for the fig/fig wasp mutualism. The gall midge is thought to be a new species belonging to the Ficiomyia family. The parasitoid share morphological similarities with the Physothorax family. However, both species need further investigation for proper identification. The gall midge had a significant negative effect on the fig/fig wasp mutualism’s reproductive success. Figs with gall midges inside had less flowers and a lower number of fig wasp offspring. Although, the effect on the reproductive success is small with low gall midge infestation rates.
