Abstract: A new species of inquiline gall wasp, Synergus nanlingensis Wang & Zeng, sp. nov., which was reared from galls on Castanopsis eyrei Tutch (Fagaceae) collected in Guangdong Province, China, is described and illustrated herein along with its mitochondrial genome. The mitogenome of S. nanlingensis is 16,604 base pairs in length and comprises 37 genes, which is typical of mitogenomes. One large control region was detected in the S. nanlingensis mitogenome, which differed from that reported for other Cynipidae species. Similar to other Cynipidae species, S. nanlingensis has the same four common gene rearrangement events; however, it shows some differences, as follows: trnS1 is downstream of Cytb; trnS2 is upstream of nad1; and trnC is downstream of rrnS. Phylogenetic analysis using COI, CytB, and 28S-D2 sequences confirmed that S. nanlingensis is a distinct species belonging to the genus Synergus Hartig.

On the specific epithet “vaccinii” of Ashmead, 1887 and Burks, 1979 (Hymenoptera, Cynipidae) https://jhr.pensoft.net/article/110687/ Journal of Hymenoptera Research 96: 955-965

DOI: 10.3897/jhr.96.110687

Authors: Juli Pujade-Villar, Y. Miles Zhang, Matthew L. Buffington, Denis J. Brothers, Irene Lobato-Vila, Victor Cuesta-Porta

Abstract: Ashmead (1887) provided descriptions of two species of Cynipidae with “vaccinii” as the specific epithet: Solenozopheria vaccinii Ashmead, 1887 and Acraspis vaccinii Ashmead, 1887. There are numerous nomenclatural issues that have arisen from these descriptions. To resolve them, we have examined all relevant primary types and provide images of these specimens, as well as their labels. We recognize as valid the two “vaccinii” species, Loxaulus vaccinii (Ashmead, 1887) and Zopheroteras vaccinii (Ashmead, 1887), and list their synonyms. We also include the following new nomenclatural and taxonomic acts: Acraspis vaccinii Ashmead, 1887: lectotype by present designation; Callirhytis vaccinii Burks, 1979: species incertae sedis; Andricus impositus Beutenmüller, 1918: revalidated status; Andricus verifactor Kinsey, 1922: new status.

Cecinothofagus Nieves-Aldrey & Liljeblad (Hymenoptera, Cynipidae) is likely an endoparasitoid of the gall-maker genus Aditrochus Rübsaamen (Hymenoptera, Pteromalidae) https://jhr.pensoft.net/article/89507/ Journal of Hymenoptera Research 93: 33-42

DOI: 10.3897/jhr.93.89507

Authors: Jean-Yves Rasplus, José-Luis Nieves-Aldrey, Astrid Cruaud

Abstract: Paraulax Kieffer and Cecinothofagus Nieves-Aldrey & Liljeblad (Cynipidae: Paraulacini) were long supposed to be gall-makers on southern beeches (Nothofagus, Nothofagaceae). Dissections of galls on Nothofagus Blume, suggested that Cecinothofagus could be instead either endoparasitoid or inquiline of Aditrochus larva (Chalcidoidea). We sequenced the universal COI barcode and Ultra-Conserved Elements (UCEs) from young larvae of Aditrochus collected from galls on Nothofagus and highlighted that one of them also contained DNA from Cecinothofagus ibarrai Nieves-Aldrey & Liljeblad. So far, when galls attributed to Aditrochus were dissected in early development stages they all contained only a single larva and no remains of other larvae. Conversely, when Cecinothofagus ibarrai was reared from galls on Nothofagus, remains of the host larva were observed inside the larval chamber. Altogether, biological observations and molecular results suggest that Cecinothofagus ibarrai is likely an endoparasitoid of Adritrochus. This result confirms the tribe Paraulacini as being entomophagous and supports the hypothesis of an ancestral parasitoid lifestyle for Cynipoidea.

Eupelmus messene Walker, 1839 and E. microzonus Förster, 1860 as parasitoids of Aulacidea hieracii (Bouché, 1834) (Hymenoptera, Eupelmidae, Cynipidae) https://jhr.pensoft.net/article/68556/ Journal of Hymenoptera Research 84: 87-102

DOI: 10.3897/jhr.84.68556

Authors: Vladimir E. Gokhman, Matvey I. Nikelshparg

Abstract: In the southeast of European Russia, the gall wasp Aulacidea hieracii (Bouché, 1834) is attacked by ten parasitoid species, including Eupelmus (Eupelmus) microzonus Förster, 1860 and E. (Macroneura) messene Walker, 1839. Although both members of the genus Eupelmus Dalman, 1820 are idiobiont ectoparasitoids, they demonstrate different life-history strategies in respect to many bionomic features. Specifically, E. messene is represented by brachypterous thelytokous females which lay single eggs directly onto the host body. This species can parasitize both concealed and exposed larvae and pupae of A. hieracii, but fails to attack its primary parasitoids. On the contrary, arrhenotokous males and females of E. microzonus are fully winged. These parasitoids usually lay several eggs per host which are placed onto the wall of the host chamber and covered with a particular fibrous substance. E. microzonus never parasitizes pupae or exposed larvae, although it can readily attack concealed larvae of A. hieracii and its primary parasitoids. In addition, hibernating individuals of E. messene undergo obligatory larval diapause, but those of E. microzonus are able to develop without exposure to subzero temperatures. All these data collectively suggest that the former species is highly specialized to exploit A. hieracii as a host, whereas the latter one mostly exhibits the so-called morphotypical specialization. These different strategies allow E. messene and E. microzonus to coexist on the same host species, as a local specialist and a more or less evenly distributed generalist, respectively.

The great greenbriers gall mystery resolved? New species of Aprostocetus Westwood (Hymenoptera, Eulophidae) gall inducer and two new parasitoids (Hymenoptera, Eurytomidae) associated with Smilax L. in southern Florida, USA https://jhr.pensoft.net/article/59466/ Journal of Hymenoptera Research 80: 71-98

DOI: 10.3897/jhr.80.59466

Authors: Michael W. Gates, Y. Miles Zhang, Matthew L. Buffington

Abstract: Aprostocetus smilax Gates & Zhang, sp. nov., is described from stem and leaf galls on Smilax havanensis Jacq. in southern Florida, USA. It is the third species of Aprostocetus Westwood known to induce plant galls. Two parasitoids of A. smilax are also described: Phylloxeroxenus smilax Gates & Zhang sp. nov. and Sycophila smilax Gates & Zhang, sp. nov. We conclude that A. smilax is the true gall inducer on Smilax L., and thus the host records of Diastrophus smilacis Ashmead and its inquiline Periclistus smilacis Ashmead, both from Smilax, are erroneous.

Revision of Canadian Eurytomidae (Hymenoptera, Chalcidoidea) associated with galls induced by cynipid wasps of the genus Diplolepis Geoffroy (Hymenoptera, Cynipidae) and description of a new species https://jhr.pensoft.net/article/13466/ Journal of Hymenoptera Research 61: 1-29

DOI: 10.3897/jhr.61.13466

Authors: Y. Miles Zhang, Michael W. Gates, Joseph D. Shorthouse

Abstract: Eurytomids are small parasitic wasps associated with many communities of phytophagous insects. In most cases, the accurate identification of eurytomids is impeded by inadequate species descriptions that do not include figures of diagnostic features, and keys that are difficult to use. Here, diagnostic features and redescriptions are provided for both sexes of the eurytomids associated with galls induced by cynipid wasps of the genus Diplolepis Geoffroy found on shrub roses across Canada. Consequently, six species of Eurytoma Illiger, along with Tenuipetiolus ruber Bugbee, are dealt with. One new species, Eurytoma shorthousei Zhang & Gates, sp. n., is described. Two species are synonymized, E. hebes Bugbee, 1973 and E. spina Bugbee, 1951 under E. longavena Bugbee, 1951, syn. n. Several new host and distribution records are reported. A dichotomous key is provided for both sexes of all seven species using photographs and scanning electron microscopy images.

New Dryocosmus Giraud species associated with Cyclobalanopsis and non-Quercus host plants from the Eastern Palaearctic (Hymenoptera, Cynipidae, Cynipini) https://jhr.pensoft.net/article/9890/ Journal of Hymenoptera Research 53: 77-162

DOI: 10.3897/jhr.53.9890

Authors: Chang-Ti Tang, Istvan Miko, James A. Nicholls, Szabina Schwéger, Man-Miao Yang, Graham N. Stone, Frazer Sinclair, Miklós Bozsó, George Melika, Zsolt Pénzes

Abstract: Our knowledge about gall wasps associated with the diverse East Asian oaks, Castanopsis and Cyclobalanopsis, is limited due to the lack of extensive field 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 five 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 identification 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.
