New dryocosmus giraud species associated with cyclobalanopsis and non-quercus host plants from the eastern palaearctic (hymenoptera, cynipidae, cynipini)

Abstract

Our knowledge about gall wasps associated with the diverse East Asian oaks, Castanopsis and Cyclobalanopsis, is limited due to the lack of extensive feld studies. Here, we describe twelve new oak gall wasp species, Dryocosmus cannoni Schwéger &Tang, D. caputgrusi Tang &Schwéger, D. crinitus Schwéger &Tang, D. harrisonae Melika &Tang, D. hearni Melika &Tang, D. hualieni Schwéger &Tang, D. konradi Tang &Melika, D. liyingi Melika &Tang, D. moriius Tang &Melika, D. quadripetiolus Schwéger &Tang, D. salicinai Schwéger &Tang, and D. taitungensis Tang &Melika, from Taiwan and mainland China. Seven newly described species induce galls on Quercus subgenus Cyclobalanopsis and fve on other Fagaceae genus, Castanopsis. All of the new species concepts are supported by morphological and molecular data. We provide descriptions, diagnoses, host associations for the new species and an illustrated identifcation key to Eastern Palaearctic Dryocosmus species. We represent natural language phenotypes in a semantic format supported by biomedical ontologies to increase the accessibility of morphological data.
