A new name for Amphibolips kinseyi Cuesta-Porta amp; Pujade-Villar and a revised key to the Amphibolips 'nassa' species-complex from Mexico and Central America (Hymenoptera: Cynipidae).

Three days before the paper "Revision of the Amphibolips species of the 'nassa' species-complex from Mexico and Central America (Hymenoptera: Cynipidae)" was published in Zootaxa, another paper describing three new Amphibolips species from Mexico was published in ZooKeys. As a result, two different species have been described under the same name, 'Amphibolips kinseyi'. To solve this homonymy, a new name Amphibolips comini Cuesta-Porta Pujade-Villar, nom. nov. is proposed for replacing A. kinseyi Cuesta-Porta Pujade-Villar, 2020, a junior homonym of A. kinseyi Nieves-Aldrey Castillejos-Lemus, 2020. Accordingly, new keys for adults of the Amphibolips 'nassa' species-complex and their associated host galls, including all known species from Mexico and Central America are provided.

Description of three new species of oak gallwasps of the genus Amphibolips Reinhard from Mexico (Hymenoptera, Cynipidae).

Three new species of oak gall wasps of the genus Amphibolips Reinhard, 1865 (Hymenoptera: Cynipidae: Cynipini) are described from Mexico: Amphibolips magnigalla Nieves-Aldrey & Castillejos-Lemus, Amphibolips kinseyi Nieves-Aldrey & Castillejos-Lemus and Amphibolips nigrialatus Nieves-Aldrey & Castillejos-Lemus. The specimens of the first two species were representative of sexual generations and come from the State of Oaxaca, while only a female, collected in the State of Veracruz, is described for A. nigrialatus. The new species induces galls on Quercus zempoaltepecana and Q. sapotifolia (Fagaceae, section Lobatae, red oaks). Descriptions of the diagnostic morphological characteristics of the three species and a key for their identification are provided. The taxonomic relationships of the new species with other species of Amphibolips are discussed; the three new species are closely allied amongst themselves and are related to A. dampfi Kinsey, 1937. With the three newly-described species, the number of Amphibolips in Mexico is increased to 23.

A new genus of oak gallwasp, Coffeikokkos Pujade-Villar & Melika, gen. n., with a description of a new species from Costa Rica (Hymenoptera, Cynipidae).

A new genus of oak gallwasp, Coffeikokkos Pujade-Villar & Melika, gen. n., is described from Costa Rica. Diagnostic characters and generic limits of the new genus are discussed in detail. The new genus includes Coffeikokkos copeyensis Pujade-Villar & Melika, sp. n., which induces galls on stems of Quercus bumelioides, an endemic oak to Costa Rica, Honduras and Panama. The new species and galls are described and illustrated.
