Overview of the current status of Charipinae (Hymenoptera, Cynipoidea, Figitidae): taxonomy, distribution, and diversity.

The subfamily Charipinae (Hymenoptera: Cynipoidea: Figitidae) has had a problematic taxonomic history as many species have been described without comprehensive revisions being undertaken. Reliably identifying these species based on morphological assessment has been almost impossible. Recently, the types of all species have been re-examined and photographed, resulting in numerous taxonomic corrections that have been published elsewhere.

Revision of the Amphibolips niger group with the description of a new species (Hymenoptera: Cynipini).

A catalogue, revision, and regional perspective of Eastern Palaearctic and Oriental oak gall wasps and their inquilines (Hymenoptera: Cynipidae: Cynipini, Synergini, Ceroptresini).

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. This process has propagated some taxonomic errors and involves many taxa whose taxonomic status is uncertain. To provide a stable foundation for further advance, here we review the taxonomic status of the 212 species (133 oak gall wasps and 79 oak cynipid inquilines) that have been described or recorded in these regions.

Local and downstream cumulative effects of traditional meadow management on stream-water quality and multiple riparian taxa.

Water quality and riparian communities are among the most affected stream components by agriculture. However, little is known about the effects of riparian management for both aquatic and terrestrial taxa at different spatial scales. Here, we surveyed aquatic (diatoms) and terrestrial taxa (bryophytes, vascular plants, litter-dwelling snails, and ground and volant arthropods), to compare the abundance and richness of riparian taxa and chemical quality between reference and exposed sites in two stream reaches each of c.

A new species, Diplolepis valtonyci Zhu, Wang Pujade-Villar sp. nova, is described from Rosa rugosa Thunb. (1784) and R.

The genus Synergus Hartig (Hymenoptera: Cynipidae: Synergini) in the New World: a complete taxonomic revision with a key to species.

A complete revision of the genus Synergus Hartig (Hymenoptera: Cynipidae: Synergini) in the New World (Nearctic and Neotropical regions) is conducted for the first time in order to stabilize its taxonomy. A total of 11 new species are described from Mexico: S. ashmeadi Lobato-Vila Pujade-Villar, sp.

A new species of Cerroneuroterus Melika Pujade-Villar from the Eastern Palaearctic (Hymenoptera, Cynipidae, Cynipini).

Andricus forni Pujade-Villar Nicholls n. sp., a new species of oak gallwasp from China (Hymenoptera: Cynipidae).

A new sexual form of a gallwasp, Andricus forni Pujade-Villar Nicholls n. sp., is described from China (Zhejiang province) based on males, females and galls collected on Quercus serrata.

Synergus Hartig species group (Hymenoptera: Cynipidae: Synergini) with partially smooth mesopleurae from the New World.

Inquiline oak gall wasps from the genus Synergus Hartig (Hymenoptera: Cynipidae: Synergini) that occur in the New World should be classified into the following morphological groups: i) species with the radial cell of fore wings open; ii) species with the radial cell of fore wings closed and mesopleurae completely sculptured, always with transversal striae covering its surface; iii) species with the radial cell of fore wings closed and mesopleurae partially smooth, with the speculum always shiny and not sculptured. The latter group, which appears to be unique to the New World's fauna, is the focus of this study. An exhaustive taxonomical revision of all the Synergus species within this morphological group is carried out for the first time after the initial treatment by Lobato-Vila Pujade-Villar (2017).
