Torymus atriplicis
(Huber, 1927)
Torymus atriplicis is a of in the Torymidae, described by Huber in 1927. The Torymus contains numerous species that parasitize insects developing within plant galls, including psyllids and gall wasps. Specific details regarding the and associations of T. atriplicis remain poorly documented in available literature.

Identification
Torymus are small chalcidoid wasps, typically 2–5 mm in length, with metallic coloration ranging from green to blue or bronze. Members of the Torymus can be distinguished from related by a combination of antennal segment counts, mesosomal sculpturing patterns, and ovipositor length relative to body size. Species-level identification within Torymus requires examination of microscopic characters including wing venation, propodeal structure, and male genitalia. No diagnostic features specific to T. atriplicis are documented in the provided sources.
Diet
Larval stage feeds as a on gall-inhabiting insects. Based on the specific epithet "atriplicis" and documented of , the likely parasitizes insects associated with Atriplex (saltbush) plants, though this relationship requires verification.
Host Associations
- Atriplex - probable plant (inferred from specific epithet)The specific epithet "atriplicis" suggests association with Atriplex, but direct records are not confirmed in available sources.
Behavior
females use a visible ovipositor to insert into plant galls containing insects. Larvae develop within the gall, feeding on the gall inducer or other gall inhabitants.
Ecological Role
Acts as a , potentially regulating of gall-forming insects. Torymus contribute to the complex of natural enemies associated with plant galls.
Similar Taxa
- Torymus californicusBoth are Torymus associated with gall ; T. californicus is documented from oak apple galls in California, while T. atriplicis likely occupies a different system based on its specific epithet.
- Psyllaephagus spp.Both are chalcidoid of psyllids; Psyllaephagus ( Encyrtidae) can be distinguished from Torymus by antennal club structure and wing venation patterns.

Taxonomic Note
The specific epithet "atriplicis" is a Latin genitive form indicating association with the plant Atriplex (Chenopodiaceae/Amaranthaceae), commonly known as saltbush or orache. This naming convention strongly implies the was described from specimens reared from galls on Atriplex, though the original description by Huber (1927) has not been consulted for this record.
