Introduction
Since more than thirty years my main research line has been focused in Taxonomy and Systematics of Hymenoptera Cynipoidea, especially on the well known gall wasps (Cynipidae). Our actual research lines include phylogeny and evolution of Cynipoidea, based in morphological and molecular data, phylogeography and Bar-coding of gall wasps, inquilines and parasitoids, comparative morphological studies of cynipid adult and larvae, and morphology and phylogeny of immature stages of gall wasps and their inquilines and Chalcidoidea parasitoids. I was involved in research projects on the diversity of gall wasps in Spain, Europe, Chile, Panama, Colombia, México and South Africa. Recently we are also working with the invader Asian gall wasp Dryocosmus kuriphilus in Spain.

A new genus of herb gall wasps, Fumariphilus Nieves-Aldrey gen. nov., (Hymenoptera, Cynipidae, Aulacideini), is described. Previous molecular phylogenetic analyses, and resulting systematic changes at the tribe level, have shown that the related species Aylax hypecoi Trotter and Neaylax versicolor Nieves-Aldrey have been incorrectly placed within

Gall wasps (Hymenoptera: Cynipidae) comprise 13 distinct tribes whose interrelationships remain incompletely understood. Recent analyses of ultra‐conserved elements (UCEs) represent the first attempt at resolving these relationships using phylogenomics. Here, we present the first analysis based on protein‐coding sequences from genome and transcript...
One of the most prominent problems related to biological invasions is the variation of local species composition, which often leads to ex novo interspecific interactions. Here, we explored and analysed the native species composition of gall inducers and their associated parasitoids and inquilines in Spanish areas invaded by Dryocosmus kuriphilus Ya...
In recent years, new wasp species and genera of Cynipidae have been described, and their species delimitation and evolutionary relationships have been supported using molecular markers. However, few studies have included comprehensive and extensive sampling of specimens across the complete distribution of a single genus. In this study, we analysed...
Fig pollinating wasps (Hymenoptera: Chalcidoidea: Agaonidae) constitute a key ecological role since they are the only known pollinators to Ficus (Moraceae), founding complex food webs. Taxonomy of Agaonidae is relatively well known due to their ecological importance and their mutualistic closed relationship with Ficus. However, the spatial and temp...
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...
Chalcidoidea are mostly parasitoid wasps that include as many as 500 000 estimated species. Capturing phylogenetic signal from such a massive radiation can be daunting. Chalcidoidea is an excellent example of a hyperdiverse group that has remained recalcitrant to phylogenetic resolution. We combined 1007 exons obtained with Anchored Hybrid Enrichme...

Andricus dentimitratus (Rejtõ, 1887) and Andricus pictus (Hartig, 1856) are two European gall wasps (Hymenoptera, Cynipidae) that induce galls on species of Quercus. The distribution and ecological niches of these species have not been studied in detail, though they are known to have a different distribution pattern in the Iberian Peninsula in Euro...
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 th...
Capturing phylogenetic signal from a massive radiation can be daunting. The superfamily Chalcidoidea is an excellent example of a hyperdiverse group that has remained recalcitrant to phylogenetic resolution. Chalcidoidea are mostly parasitoid wasps that until now included 27 families, 87 subfamilies and as many as 500,000 estimated species. We comb...
The phylogeny of gall wasps (Cynipidae) and their parasitic relatives has attracted considerable attention in recent years. The family is now widely recognized to fall into thirteen natural lineages, designated tribes, but the relationships among them have remained elusive. This has stymied any progress in understanding how cynipid gall inducers ev...
Nothofagus obliqua (Nothofagaceae) is a native tree to Chile, which hosts at least seven gall morphotypes, two of them induced by Hymenoptera, Pteromalidae. The life cycle of these pteromalids, particularly the feeding activity of their larvae, has a high impact on host plant tissues toward new shapes and functions, leading the gall formation. The...
Hymenoptera evolved structures on the legs which are able to remove particles from their antennae through grooming behaviour. The antenna cleaner (strigil) consists of an apical and modified protibial spur (calcar, composed of a trunk and a velum) and a modified basitarsus including a fine comb made up of setae and a notched inner surface. In "Tere...
A new genus, Prokius Nieves Aldrey, Medianero & Nicholls, gen. nov., and two new species of oak gall wasps (Hymenoptera: Cynipidae: Cynipini), Prokius cambrai Medianero & Nieves-Aldrey sp. nov. and Prokius lisethiae Medianero & Nieves-Aldrey sp. nov., are described from adults reared from galls on Quercus bumelioides Liebm (Fagaceae, sect. Quercus,...
The host range of parasitoids varies greatly among species: Some only parasitize
one to a few hosts (specialists), while others parasitize multiple species or a variety
of host types (generalists). The direction of most host range shifts in parasitoid
groups, that is from generalist to specialist or, alternatively, from specialist
to generalist, is...

The success of invasive species largely depends on the resistance offered by the native communities. Dryocosmus kuriphilus is a cynipid native from China that is a serious pest of chestnuts worldwide. This species recruits natural enemies in the areas of introduction; nevertheless, their role in regulating pest population is frequently questioned,...
1. Parasites are one of the main actors in host–parasite interactions. Still, their role as a prey and the related consequences for such interactions and in other respects, such as food webs, are frequently overlooked.
2. This paper analyses predation pressure on a ubiquitous avian ectoparasitic fly, Carnus hemapterus, identifies their main natural...
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...

Temporal comparisons of a site’s biodiversity depend on the availability of at least two asynchronous data sets on a bioindicator group. The Sierra de Guadarrama, a mountain range in central Spain has a high biodiversity and representative sites such as El Ventorrillo Biological Station (Madrid province) play an important role in research and monit...
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...
Mating behaviour in insects is largely mediated by chemical signals emitted by one sex and recognized by the other (sex pheromones). A particular type of integumentary gland produces a sex pheromone in the antennae of male Cynipoidea (Hymenoptera), a rich and diverse wasp group consisting of species forming galls on plants, species which act as inq...
The alien cynipid wasp Dryocosmus kuriphilus Yasumatsu, 1951 is a serious pest of chestnuts ( Castanea spp.) in Japan, North America and Europe, causing fruit losses while inducing galls in buds. While D. kuriphilus galls have a recognizable and roughly invariable globular shape, their size varies, reaching up to 4 cm in diameter. Among other facto...
