The Genevan entomologist Frédéric Chevrier (1801-1882) was interested in natural history from an early age and amassed an important collection of Coleoptera which he was forced to sell in 1849 because of financial difficulties. After this he led a quiet life near Nyon in the canton of Vaud (Switzerland), where he began collecting Hymenoptera and pu...

Germany is home to a rich cuckoo wasp fauna (Hymenoptera: Chrysididae) with about 108 species. However, several nomenclatural changes, the lack of identification keys, and the discovery of cryptic species difficult to identify based on external morphology have made the identification of several species a challenge. COI barcoding has been instrument...

This paper presents the current list of all species of aculeate wasps (excluding Dryinidae, Bethylidae, Embolemidae) recorded in Germany. This checklist of 592 species forms the basis for the forthcoming revision of the corresponding Red Lists. We also provide German names for all species.

New data on the Chrysididae fauna from Yemen are presented.

An overview on the history of the British cuckoo wasps is presented. Some very old publications dealing with this fauna have fallen into oblivion, along with the description of some taxa. In the present paper I discuss these taxa and other species observed in museum collections. The species formerly identified as Cleptes semicyaneus Tournier, 1879...

The fundamental value of universal nomenclatural systems in biology is that they enable unambiguous scientific communication. However, the stability of these systems is threatened by recent discussions asking for a fairer nomenclature, raising the possibility of bulk revision processes for "inappropriate" names. It is evident that such proposals co...

Morocco is considered to be one of the main diversity hotspots of bees in the Mediterranean basin. However, this fauna remains largely understudied in both urban and natural eco-systems. Bee monitoring primarily conducted during 2023 in an urban area (i.e. Safi) has unveiled three new bee species for Morocco: Lithurgus tibialis, Tetralonia aff. lan...

Chrysididae fossils are rare and understudied compared to their extant diversity, with an overwhelming proportion of genera found in Cenozoic fossiliferous deposits currently thought to be extinct. Here, we document the oldest known representative of the extant genus Primeuchroeus Linsenmaier, 1968 based on a specimen from Priabonian (upper Eocene)...

Hedychridium wahisi Niehuis, 1998, an Italian endemism

Aberrations involving the metasoma in Hymenoptera are well-documented, with one notable teratological case being the fusion of metasomal terga, named symphysomery. This aberration, characterized by the fusion of the second and third terga, has been observed in various species groups of Hedychridium, spanning from Southern Africa to Central Asia. Si...

All species of the Chrysis angolensis group were synonymised with C. angolensis Radoszkovsky, 1881, excluding Chrysis diademata Mocsáry, 1889, endemic of the Philippines. However, after the study of type materials, four species are herein resurrected: Chrysis callaina Gribodo, 1884 stat. reviv., C. erratica Abeille de Perrin and du Buysson in du Bu...

The BBSG is commissioned by the IUCN Species Survival Commission (SSC), with responsibilities centred around the Red List assessment of all bumblebee species world-wide (currently interpreted at ca 290 species). It has been running for more than two IUCN quadrennia and has completed first assessments for most of the species of the New World and Eur...

Italy lies at the centre of the Mediterranean basin and has a large bee fauna due to its mixture of Mediterranean and temperate habitats, and infl uences from all cardinal directions. This is true also for the genus Andrena; however, studies to date have been fragmentary, and there has been no focused critical revision of the entire fauna. Here the...

The host-brood parasite relationship of the cuckoo wasp Euchroeus purpuratus (Fabricius, 1787) (Chrysididae) to the hairy sand wasp, Podalonia hirsuta (Scopoli, 1763) (Sphecidae), as assumed in old literature, has been doubted in the past because the cuckoo wasp is extremely rare in contrast to its host. The first author observed and photographical...

A recent examination of type specimens and unidentified Indian cuckoo wasps deposited at the Natural History Museum (London) and at the Oxford University Museum of Natural History led to the discovery of: two new Indian species, Chrysis parviocula sp. n. (amneris species group) and Elampus bicolor sp. n.; a new synonymy, Chrysis quaerita Nurse, 190...

Chrysis poggii n. sp. is described from Indonesia (Java, Sumatra, and the nearby smaller islands of Ambon, Bali, Bawean, Flores, Kangean, Sumbawa, and Palau Panaitan). Specimens of this taxon were previously misidentified as C. comottii Gribodo, 1884 (repl. name for C. insularis Smith, 1859 nec Guérin-Méneville, 1842) by most taxonomists, thus obsc...

Chrysidid wasps adopt different strategies to enter host nests whilst evading detection. However, the specific oviposition strategies of most species are still largely unknown, and it has only become evident in recent years that some brood parasitic species are actually endoparasitoids in intermediate hosts that serve as the prey of their final hos...

Pollinators play a crucial role in ecosystems globally, ensuring the seed production of most flowering plants. They are threatened by global changes and knowledge of their distribution at the national and continental levels is needed to implement efficient conservation actions, but this knowledge is still fragmented and/or difficult to access. As a...
