Revision of Phoenoteleia Kieffer (Hymenoptera, Scelionidae, Scelioninae) https://jhr.pensoft.net/article/59794/ Journal of Hymenoptera Research 87: 575-611

DOI: 10.3897/jhr.87.59794

Authors: Zachary Lahey, Luciana Musetti, Lubomír Masner, Norman F. Johnson

Abstract: The genus Phoenoteleia Kieffer is revised. Phoenoteleia canalis Dodd, P. rufa Kieffer, and P. rufescens (Kieffer) are redescribed, P. fusca (Kieffer) is transferred to Dicroscelio Kieffer as Dicroscelio fuscus (Kieffer), comb. nov., and six species are described as new: P. buka Lahey, sp. nov. (Fiji), P. gunnelsi Lahey, sp. nov. (Indonesia), P. halua Lahey, sp. nov. (Indonesia), P. kaca Lahey, sp. nov. (Indonesia), P. kuboa Lahey, sp. nov. (Fiji), and P. sanma Lahey, sp. nov. (Vanuatu). The difficulty in associating male and female specimens is discussed. A key is provided to differentiate between the species of Phoenoteleia and the putative closely related genera Mallateleia Dodd and Oxyteleia Kieffer.

Fighting injuries, fig exit, and dimorphism in two species of sycoryctine fig wasp (Chalcidoidea, Pteromalidae) https://jhr.pensoft.net/article/36461/ Journal of Hymenoptera Research 74: 105-121

DOI: 10.3897/jhr.74.36461

Authors: Da-Mien Wong, Anthony Bain, Shiuh-Feng Shiao, Lien-Siang Chou

Abstract: Similar to many vertebrate and invertebrate species, many fig wasp species are fighting other members of their species for mates. Fighting between the males of many non-pollinating fig wasp species involves injuries and fatalities. Studies have shown that large males fight for mates, whereas conspecific small males tend to adopt nonfighting, sneaky behaviors. To analyze male morphs in two non-pollinating fig wasps (Philotrypesis taida Wong & Shiao, 2018 and Sycorycteridea taipeiensis Wong & Shiao, 2018) associated with the fig tree Ficus benguetensis, the head and mandible allometry and injuries were examined as well as the morphologies of their heads and mandibles. Male fig wasps of these two nonpollinating species can be divided into two morphological groups according to their head and mandible shapes. Approximately 88% of the Philotrypesis and 62% of the Sycorycteridea males were injured and no males belonging to largest morphs were decapitated. Moreover, nearly 31% of the Philotrypesis and 45% of the Sycorycteridea males left their natal figs. No difference in injury level or male exit rate between the male morphs was observed. This study reveals slight morphological and behavioral differences that may hint towards different mating strategies among morphs.

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.

A new species of Encarsia (Hymenoptera, Aphelinidae) developing on ficus whitefly Singhiella simplex (Hemiptera, Aleyrodidae) in China and Taiwan https://jhr.pensoft.net/article/5155/ Journal of Hymenoptera Research 46: 85-90

DOI: 10.3897/JHR.46.5155

Authors: Chiun Cheng Ko, Yuan Tung Shih, Stefan Schmidt, Andrew Polaszek

Abstract: Encarsia singhiellae Polaszek & Shih, sp. n., is described and illustrated. It is known so far from Taiwanand China. All specimens were reared from the ficus, or fig, whitefly Singhiella simplex (Singh), an Asian species recently attaining pest status in California, Colombia, and Florida.

Revision of Agathacrista new genus (Hymenoptera, Braconidae, Agathidinae, Agathidini) https://jhr.pensoft.net/article/1638/ Journal of Hymenoptera Research 33: 99-112

DOI: 10.3897/jhr.33.4373

Authors: Michael Sharkey, Stephanie Stoelb

Abstract: Based on a cladistic analysis, a new genus of Agathidini, Agathacrista Sharkey, is proposed and its phylogenetic position hypothesized. Two previously described (Agathacrista cancellata, Agathacrista depressifera) and three new species (Agathacrista sailomi, Agathacrista winloni, Agathacrista krataeii) are included. The distribution of Agathacrista is limited to the Oriental region and southern portion of the eastern Palearctic.

Two new species of the genus Discoelius Latreille (Hymenoptera, Vespidae, Eumeninae) from China, with a key to the Chinese species https://jhr.pensoft.net/article/1634/ Journal of Hymenoptera Research 32: 45-54

DOI: 10.3897/jhr.32.4958

Authors: Xin Zhou, Bin Chen, Tingjing Li

Abstract: Two new species, namely Discoelius nigriclypeus Zhou and Li, sp. n. from Hunan, China, and Discoelius emeishanensus Zhou and Li, sp. n. from Sichuan, China, are described. A key to the Chinese species of the genus is provided, along with illustrations of the new species. Type specimens of these two new species are deposited in the Institute of Entomology and Molecular Biology, Chongqing Normal University.
