Galeopsomyia
Galeopsomyia is a New World genus of minute parasitoid wasps in the family Eulophidae. Species within this genus function as hyperparasitoids, attacking gall-inducing wasps of the genera Eurytoma and Torymus, and have been documented as parasitoids of gall midges (Cecidomyiidae) and the citrus leafminer. A notable species was fortuitously discovered providing biological control of the citrus pest Phyllocnistis citrella. The genus exhibits intraspecific phenotypic matching in ovipositor size relative to gall thickness.
