Kokkocynips coxii

Identification requires examination of morphological characters used to distinguish Kokkocynips from related genera such as Dryocosmus and Callirhytis. The 2021 systematic revision provides a key for the identification of asexual generations of seven Kokkocynips species. Specific diagnostic characters for K. coxii are detailed in the original description and re-description.

Associated with red oak (Quercus section Lobatae) forests in the Nearctic region.

Nearctic region (Canada and United States). Historical records as Dryocosmus coxii and subsequent transfer to Kokkocynips in 2021.

• Quercus section Lobatae - gall inducerRed oaks (Fagaceae); inferred from genus-level association

Has been observed to have an asexual generation; sexual generation unknown or unconfirmed.

Gall inducer on oaks; modifies plant tissue to form protective structures for larval development.

• Dryocosmus spp.Previously classified under Dryocosmus; distinguished by morphological and molecular characters supporting placement in Kokkocynips
• Kokkocynips doctorrosaeCongeneric species; distinguished using morphological characters in the provided identification key
