Isosomodes
Ashmead, 1888
Isosomodes is a of in the , first described by Ashmead in 1888. The genus is part of the diverse Eurytominae , whose members are primarily associated with plants as seed feeders or formers. Records indicate presence in the Americas, with documented occurrences in Venezuela, Colombia, and the United States. The genus remains poorly studied, with limited -level documentation and biological data available.

Identification
Members of Isosomodes can be distinguished from other by features of the genus-level , though specific diagnostic characters are not well-documented in accessible literature. As with other Eurytomidae, are small (typically 1-5 mm), with reduced and a distinct . Separation from closely related genera requires examination of microscopic characters including antennal segmentation, mesosomal , and structure.

Distribution
Recorded from Venezuela, Colombia, and the United States. The sparse occurrence records suggest either limited sampling effort or genuinely restricted distribution, with most records concentrated in northern South America.
Ecological Role
As , members likely function as associated with reproductive structures, potentially acting as seed or inducers on plants. The specific ecological role of Isosomodes has not been documented.

Taxonomic Status
The Isosomodes was established by William H. Ashmead in 1888. It has received limited taxonomic attention since its description, and the number of included , their identities, and validity remain uncertain. The genus is listed in major taxonomic databases but lacks comprehensive revisionary treatment.
Data Limitations
Only three iNaturalist observations are recorded for this , and GBIF holds sparse occurrence data. No -level treatments, biological studies, or records were found in major literature databases, reflecting the genus's obscurity in entomological research.
