“…C. pulicaris was used as outgroup because of the morphological similarity and numerous shared characters with its sister genus Spalangiopelta . Character states were assigned to the respective Spalangiopelta species based on (re-)descriptions in the revision by Darling (1991) or the original descriptions ( Darling, 1995 ; Mitroiu, 2016 ; Walker, 1851 ).…”

“…The characters for the new fossils were scored and added. Character states of Spalangiopelta rameli Mitroiu, 2016 andSpalangiopelta viridis Mitroiu, 2016 were retrieved from literature and added as the respective species description allowed (Table 1). Altogether, the phylogenetic analysis in the present study includes 17 ingroup species (14 extant species and three fossil species), representing all known species of Spalangiopelta (Table 1).…”

“…The subfamily contains three genera, two of which are monotypic (Mitroiu, 2016): Bohpa Darling, 1991, which is known only from South Africa, and Cea Walker 1837, which is found throughout the Western Palearctic region. The genus Spalangiopelta Masi 1922 comprises 14 extant species, eight of which are known only from the Palearctic region, whereas the other six species are Nearctic or Neotropic (Darling, 1991;Mitroiu, 2016). In addition, Darling (1996) described Spalangiopelta georgei, a fossil from Dominican amber.…”

Spalangiopelta is a small genus of chalcid wasps that has received little attention despite the widespread distribution of its extant species. The fossil record of the genus is restricted to a single species from Miocene Dominican amber. We describe two new fossil species, Spalangiopelta darlingi sp. n. and Spalangiopelta semialba sp. n. from Baltic amber. The species can be placed within the extant genus Spalangiopelta based on the distinctly raised hind margin of the mesopleuron. 3D models reconstructed from µCT data were utilized to assist in the descriptions. Furthermore, we provide a key for the females of all currently known Spalangiopelta species. The phylogenetic placement of the fossils within the genus is analyzed using parsimony analysis based on morphological characters. Phylogenetic and functional relevance of two wing characters, admarginal setae and the hyaline break, are discussed. The newly described Baltic amber fossils significantly extend the minimum age of Spalangiopelta to the Upper Eocene.

Forest decline and dieback are growing phenomena worldwide, resulting in severe, large-scale degradation of the canopy. This can profoundly alter forest microclimates and the provision of trophic resources and microhabitats for forest arthropods, especially those dwelling in the canopy. In 2019, we assessed the effect of oak decline on the community of canopy-dwelling Hymenoptera. We selected 21 oak stands, and 42 plots, located in three forests in France, presenting contrasting levels of decline. Insects were sampled at the canopy level with green multi-funnel and flight-interception traps. We collected a particularly diverse community of 19,289 insect individuals belonging to 918 taxa, eight larval trophic guilds and five nesting guilds. Oak decline had no effect on the abundance or richness of the overall community, but significantly reshaped the community assemblages. Decline had contrasting effects depending on the taxa and guilds considered. Parasitoids were more abundant at intermediate levels of decline severity. Taxa depending on ground-related resources and microhabitats were promoted. Saproxylic taxa were more diverse while xylophagous insects were negatively impacted. Reduced leaf area index promoted several guilds, and the diversity of the overall community. While an increasing tree mortality rate enhanced the abundance and diversity of deadwood resources, it had negative impacts on Hymenoptera guilds. Our results suggest that micro-environmental changes at the ground-level due to canopy decline have major cascading effects on the communities of canopy-dwelling Hymenoptera. 6. Our study highlights the relevance of studying Hymenoptera communities to investigate the outcomes of disturbances on forest biodiversity.
