Chromosomes of the asexual and sexual generation of the gall wasp Belonocnematreatae Mayr, 1881 (Cynipidae) were analyzed. Females of both generations have 2n = 20, whereas males of the sexual generation have n = 10. Cyclical deuterotoky is therefore confirmed in this species. All chromosomes are acrocentric and form a continuous gradation in size. This karyotype structure is probably ancestral...

Lithonecrus papuanus Nieves-Aldrey & Butterill, a new genus and species of inquiline oak gall wasps (Hymenoptera: Cynipidae: Synergini), is described from material reared from galls on Lithocarpus celebicus (Miq.) Rehd., collected in Papua New Guinea. The new genus and species is the first record of a cynipid from Papua New Guinea and the whole  Oceanian biogeographic region,  and represents th...

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 st...

A quantitative catalogue of the parasitoids (almost exclusively Chalcidoidea) and inquiline Cynipidae recorded in the western Palaearctic from galls induced on Quercus by Cynipidae (Cynipini) is presented. Quantitative and national data are included with bibliographic references to almost all records published in 2011 and earlier. The catalogue is followed by two checklists, firstly one of the ...

Fifteen new species of cynipid inquilines, Saphonecrus chinensis Tang & Schwéger, S. gilvus Melika & Schwéger, S. globosus Schwéger & Tang, S. leleyi Melika & Schwéger, S. lithocarpii Schwéger & Melika, S. longinuxi Schwéger & Melika, S. morii Schwéger & Tang, S. nantoui Tang, Schwéger & Melika, S. nichollsi Schwéger & Melika, S. pachylomai Schwéger, Tang & Melika, S. robustus Schwéger & Melika...

A new genus of cynipid oak gallwasp-Cyclocynips Melika, Tang, & Sinclair (Hymenoptera: Cynipidae: Cynipini), with two new species--C. uberis and C. tumorvirgae--reared from galls on oaks of the Quercus subgenus Cyclobalanopsis is described from Taiwan. Descriptions of asexual generation adults and their diagnostic characters are presented. The likelihood of yet undiscovered sexual generations a...

Barucynips panamensis Medianero & Nieves-Aldrey, a new genus and species of oak gallwasps (Hymenoptera: Cynipidae: Cynipini), is described from adults reared from galls on Quercus bumelioides in Panama. The new genus is taxonomically close to the recently described Coffeikokkos from Costa Rica, but differs from it and all of the described genera of Cynipini, by the shape and setation of the pro...
