Gall-parasitoid
Guides
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.
Rileyinae
Rileyinae is a subfamily of small wasps within Eurytomidae (Chalcidoidea), comprising parasitoids primarily associated with insect eggs and gall-formers. Members include the genus Neorileya, known as endoparasitoids of eggs from diverse Hemipteran families (Coreidae, Pentatomidae, Reduviidae) and even Tettigoniidae. The subfamily also includes Gatesina, a genus that parasitizes Eurytominae gall-formers in fruits of Myrtaceae. Rileyinae species are typically minute (2-3 mm), solitary, and part of the 'micro-Hymenoptera' fauna.
