Interpretive Summary: Gall wasps induce deformities on plant called galls. These galls can have an adverse impact on various plants, especially oaks, impacting health and altering appearance. This can be particularly problematic in urban/suburban plantings and nursery stock. Understanding the diversity and host range of these gall wasps is beneficial for implementing control measures. This paper describes the sexual generation of two gall wasps plus one new species, as well as provide molecular and morphological diagnostics. This will serve horticulturalists, ecologists, entomologists, and nursery workers

Technical Abstract: The sexual generations for D. mamillana and D. prehensa are described based on a combination of molecular and host plant data. A new species, Disholcaspis erugomamma Cooke n. sp., is described from Texas. The locations for the various type specimens and image data for a majority of the species in the genus are presented with discussion about the overall morphology of the genus. Lastly, a large image-based dataset was established for this group to aid in an eventual revision of the genus
