Uncovering the patterns and structure in species interactions is central to understanding community assembly and dynamics. Species interact via their phenotypes, but identifying and
quantifying the traits that structure species-specific interactions (links) can be challenging. Where these traits show phylogenetic signal, link properties (such as wh...
1. A key question in insect community ecology is whether parasitoid assemblages are structured by the food plants of their herbivore hosts.
2. Tritrophic communities centred on oak-feeding cynipid gallwasps are one of the best-studied tritrophic insect communities. Previous work suggests that host plant identity is a much stronger predictor of oak...
Revealing processes that structure species interactions is central to understanding community assembly and dynamics. Species interact via their phenotypes, but identifying and quantifying the traits that structure species-specific interactions (links) can be challenging. Where these traits show phylogenetic signal, however, link properties may be p...
Recent years have seen rapid advances in the study of Fagaceae-associated gall wasps (Hymenoptera: Cynipidae) of the Eastern Palaearctic and the Oriental (EPO) regions, for both the gall inducing Cynipini (commonly termed oak gall wasps though many species gall non-oak Fagaceae) and the predominantly inquiline tribes Synergini and Ceroptresini. Thi...
The monophyly and taxonomic validity of some currently accepted genera of gall wasps in the Cynipini (Hymenoptera: Cynipidae) are being challenged by recent systematic studies. Here we used morphological and molecular data to re-describe and revise the taxonomic limits of the monotypic genus Kokkocynips Pujade-Villar & Melika, previously recorded o...
A new species of inquiline, Lithosaphonecrus edurus Fang, Melika, and Tang, new species (Hymenoptera: Cynipidae: Synergini) is described from Emeishan, Sichuan Province, China. Lithosaphonecrus edurus is associated with an as yet undetermined cynipid gall on Lithocarpus cleistocarpus var. cleistocarpus and var. omeiensis, L. hancei and L. megalophy...
The known species richness of oak gallwasps in Asia has increased tremendously in the past decade. However, the vast majority of taxa have been described from the east coast of Asia, and knowledge of oak gallwasps from Central Asia is still scant. Here we use molecular and morphological characters to describe a new genus of cynipid oak gallwasp, He...
While much has been learned regarding the phylogeny and evolution of cynipoid wasps, clearly illustrated diagnostic tools and identification keys have remained stagnant. So too, where keys do exist, they are often to genus or species, and there are no user-friendly keys to groups such as tribes, subfamilies, or families. This state of affairs leave...
Cynipid gallwasps comprise 1364 species worldwide, predominantly in temperate regions of the Holarctic. The vast majority of recorded species are from the Nearctic and the Western Palaearctic, both of which are long-standing centers of research on the taxonomy and biology of this group. In contrast, the Eastern Palaearctic and the Oriental Region f...
Though this book is entitled as a guide to Insect galls, the research findings out of various scientific aspects in Cecidology have actually explored as much as possible, with pictures, paintings and drawings. We sincerely hope it can interest and lead you into this extraordinary microscopic world of insect galls.
造癭昆蟲與其寄主植物的互動可謂是昆蟲與植物交互作用最極致的表現之一。造癭昆蟲刺激植物形成新的、高度分化、具有一定的結構之癭組織，作為幼蟲成長的避難所，達成這種橫跨動物界去操縱植物界的任務，需要有很多的條件配合，而時機的掌握益形重要。造癭者需要在植物生長的適當物候(phenology)期給予刺激，同時發育過程亦須密切配合。以雙翅目癭蚋科的喜楠癭蚋屬(Daphnephila)為例，同屬多種癭蚋在同一寄主紅楠(Machilus thunbergii)形成不同形狀的蟲癭，不僅與植物的物候須同步配合，亦表現出複雜的生活史策略，尤其來自同一批母蟲的卵藉由休眠長度，發育成一年一代與兩年一代的不同生活史，此類生活史的變化還可能延伸影響到不同食物鏈階層(如天敵)間的互動，達到降低風險，增加存活機率。而台灣近年...

Our knowledge about gall wasps associated with the diverse East Asian oaks, Castanopsis and Cyclobalanopsis, is limited due to the lack of extensive feld 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 Meli...
A new species of oak gall wasp, Plagiotrochus tarokoensis Tang and Melika sp. nov., is described from Taiwan. The species induces integral leaf galls on Quercus tarokoensis (Fagaceae). Data on the diagnosis, distribution, and biology of the new species are given. This is the second known Plagiotrochus species from the Oriental region and the first...
Eight new species of cynipid gallwasps, Cycloneuroterus abei Melika & Tang, C. ergei Tang & Melika, C. gilvus Melika & Tang, C. globosus Melika & Tang, C. jianwui Tang & Melika, C. lohsei Melika & Tang, C. tumiclavus Tang & Melika, C. uraianus Tang & Melika, from Taiwan and mainland China are described. Descriptions, diagnoses, biology, and host as...

The cynipid inquilines genus Saphonecrus is known to be a polyphyletic group with distinct lineages. One lineage is associated with Synophrus in the Western Palaearctic on section Cerris oaks. Another involves the type species of Saphonecrus, S. connatus, and represents a distinct and probably early-diverging lineage with a Palaearctic distribution...
Ongoing research in east and south east Asia has revealed many undescribed species of the inquiline cynipid genus Saphonecrus, suggesting that the phylogenetic relationships within this group are even more complicated than previously thought. Results of the Bayesian reconstruction of the Synergus complex of species are presented based on analysis o...
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 like...

We discuss the taxonomy of oak gallwasps (Hymenoptera: Cynipidae: Cynipini) whose lifecycle involves only Palaearctic oaks (Quercus subgen. Quercus) in the section Cerris. Recent phylogenetic reconstructions support a deep split between such Cerris-associated species in the genera Aphelonyx, Dryocosmus, Plagiotrochus, Neuroterus, Pseudoneuroterus a...
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.
