New Species Of Oak Gallwasp Research Articles

Andricus partali n. sp. from Costa Rica (Hymenoptera: Cynipidae: Cynipini)

A new species of oak gallwasp, Andricus partali n. sp. (Hym., Cynipidae: Cynipini), is described from Costa Rica inducing galls on the leaves of Q. costaricensis Liebm. (Section Lobatae). We provide a description, diagnosis, and information about the distribution and biology of the new species.

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 Cycloneuroterus Melika & Tang Oak Gallwasp Species (Hymenoptera: Cynipidae: Cynipini) Associated with Lithocarpus (Fagaceae) from Taiwan

A new species of oak gallwasp, Cycloneuroterus megaformosanus, n. sp., is described from Taiwan. The species induces integral stem swelling galls on young shoots of Lithocarpus corneus. Data on the diagnosis, distribution, and biology of this new species are given. Different Cycloneuroterus species are known to induce galls across multiple host plant genera in Fagaceae, so the evolution of host associations in this genus is also discussed briefly.

First Record ofLoxaulusMayr from Mexico, with Descriptions of Two New Species (Hymenoptera: Cynipidae, Cynipini)

Abstract. Two new species of oak gallwasp, Loxaulus hyalinus Pujade-Villar & Melika n. sp. and L. laeta Pujade-Villar n. sp. are described from Mexico. They represent the first records of this genus in Mexico. Both species are known from asexual generations and induce galls on endemic Mexican Quercus: Q. dysophylla Benth. and Q. laeta, respectively. Data on the diagnosis, distribution, and biology of the new species are given.

Four new species of Andricus Hartig oak gallwasp from Turkey <br />(Hymenoptera: Cynipidae, Cynipini)

Four new species of oak gallwasps, Andricus ahmeti, A. anatolicus, A. bakrachus and A. turcicus (Hymenoptera: Cynipidae: Cynipini) are described from Turkey. All four species are known only from asexual females and induce galls on twigs and young shoots on Q. infectoria, Q. macranthera and Q. petraea. Data on the diagnosis, distribution and biology of the four new species are given. Andricus stonei and Aphelonyx kordestanica are listed for the first time for the Turkish oak gallwasp fauna.

A new Andricus Hartig oak gallwasp species from China (Hymenoptera: Cynipidae: Cynipini)

A new species of oak gallwasp, Andricus xishuangbannaus is described from China. The species induces leaf galls on Quercus griffithii (Fagaceae). Diagnosis, distribution, and biology of the new species are included.

A new Latuspina Monzen oak gallwasp species from Taiwan (Hymenoptera: Cynipidae: Cynipini)

A new species of oak gallwasp, Latuspina manmiaoyangae sp. nov., is described in Taiwan. The species induces leaf galls on Quercus variabilis (Fagaceae). Data on the diagnosis, distribution, and biology of the new species are given. This is the second known Latuspina species.

New Amphibolips gallwasp species from Mexico (Hymenoptera: Cynipidae)

Two new species of oak gallwasp, Amphibolips zacatecaensis Melika & Pujade-Villar and A. hidalgoensis Pujade-Villar & Melika, are described from Mexico, known to induce galls on Quercus eduardi, Q. crassipes, Q. candicans and Q. crassifolia (section Lobatae, red oaks). Only females are known. Data on the diagnosis, distribution and biology of the new species are given.

Four New Species of Dryocosmus gallwasps from Taiwan (Hymenoptera: Cynipidae: Cynipini)

Four new species of oak gallwasps of the genus Dryocosmus: D. pentagonalis, D. triangularis, D. carlesiae, and D. testisimilis are described from Taiwan. They induce galls on one species of Castanopsis and one species of Lithocarpus (Fagaceae). Data on the diagnosis, distribution, and biology of the four new species is given. A key for Dryocosmus species identification of Taiwan is provided. Final comments discuss the polyphyletic nature of the Dryocosmus genus, emphasizing the urgent need for its revision.

New species of oak gallwasps from Taiwan (Hymenoptera: Cynipidae: Cynipini)

Three new species of oak gallwasps from Taiwan are described: Andricus songshui and Andricus pseudocurvator, both known to induce integral leaf galls on Quercus serrata, and Plagiotrochus glaucus which induces stem swelling-like galls on Quercus glauca. Galls and adults of new species are described; data on the diagnosis, distribution and biology of the new species and a key to the Taiwanese Andricus species are also given.

First record of an Andricus oak gallwasp from the Oriental Region: a new species from Taiwan (Hymenoptera: Cynipidae: Cynipini)

A new species of oak gallwasp, Andricus formosanus is described from Taiwan which induces integral leaf galls on Quercus dentata (Section Quercus sensu stricto). The gall and adults of the new species most closely resembles Andricus moriokae Monzen, known from Japan. Data on the diagnosis, distribution and biology of the new species is given.
