Abstract

The Nearctic cynipid oak gall wasp genus Druon Kinsey comb. rev. is re-established, with 5 new species and 10 species previously placed in the genus Andricus Hartig 1840: D. alexandri Melika, Nicholls & Stone, sp. nov., D. flocculentum (Lyon), comb. nov., D. fullawayi (Beutenmüller), comb. nov., D. garciamartinonae Pujade-Villar, sp. nov., D. gregori Melika, Nicholls & Stone, sp. nov., D. hansoni Cuesta-Porta, Melika & Pujade-Villar, sp. nov., D. ignotum (Bassett), comb. nov., D. linaria Kinsey, comb. rev., D. pattoni (Bassett), comb. nov., D. protagion Kinsey, comb. rev. (D. malinum Kinsey, syn. nov., D. polymorphae Kinsey, syn. nov.), D. quercusflocci (Walsh), comb. nov., D. quercuslanigerum (Ashmead), comb. nov., D. receptum Kinsey, comb. rev., D. rusticum Kinsey, comb. rev. and D. serretae Pujade-Villar, Cuesta-Porta & Melika, sp. nov.. All species are known only from their asexual generation except for D. ignotum and D. quercuslanigerum, for which alternating asexual and sexual generations are known. The sexual generation of D. ignotum and a new morphological variety of D. quercuslanigerum from Mexico are both described for the first time. We provide descriptions, redescriptions, diagnoses, keys to species, DNA sequence data and analyses, and information on biology, phenology, and distribution. Additionally, four Andricus species with woolly galls and striato-reticulated metasomas are transferred to Striatoandricus Pujade-Villar: S. furnessulus, comb. nov., S. furnessae, comb. nov., S. guatemalensis, comb. nov., and S. tenuicornis, comb. nov.
