Sycoscapter
Saunders, 1883
Sycoscapter is a of non-pollinating fig wasps first described by Saunders in 1883. These are native to the Afrotropical, Indomalayan, and Australasian biogeographic realms. They function as , specifically targeting fig wasps in the genera Ceratosolen, Eupristina, and Kradibia. As members of the Pteromalidae, they represent one of many lineages involved in the complex ecological networks associated with fig trees (Ficus).

Identification
Sycoscapter are small chalcidoid wasps, typical of the Pteromalidae . They can be distinguished from pollinating fig wasps (Agaonidae) by their non-pollinating ecological role and associated morphological adaptations. Specific identification to species level requires examination of microscopic features including structure, wing venation, and body sculpturing. They may be separated from other non-pollinating by associations and subtle morphological differences in the and ovipositor structure.

Habitat
Associated with fig trees (Ficus ) across tropical and subtropical regions. Occurs within the syconia (enclosed inflorescences) of figs where their hosts develop.
Distribution
Native to the Afrotropical, Indomalayan, and Australasian realms. Distribution records include China (Fujian), Japan (JP), and Papua New Guinea (PG).

Ecological Role
Acts as a in fig- , contributing to of pollinating and other non-pollinating . Part of the complex trophic web within fig syconia, which helps maintain the stability of fig- mutualisms.

Taxonomic Note
placement has varied in literature. Some sources list Sycoscapter in Agaonidae, but authoritative sources including NCBI and Catalogue of Life place it in Pteromalidae. This reflects ongoing revisions in chalcidoid .
Fig Wasp Community
Fig trees typically support of multiple including one and several non-pollinating species that may be , , or gall-makers. Sycoscapter represents the parasitoid guild within these communities.
