Scelionid wasps are arthropod egg parasitoids, many of which are relevant to global biosecurity. However, the scelionid fauna of Germany has not received much attention from professional taxonomists.
Eleven species and four genera are recorded for the first time from Germany, including species of interest to agriculture and biological control. First genus records include Baryconus Förster, Macroteleia Westwood, Paratelenomus Dodd and Probaryconus Kieffer. First species records include B. europaeus (Kieffer), Idris nigroclavatus (Kieffer), Idris semiflavus (Kieffer), M. bicolora Kieffer, M. pannonica Szabo, Paratelenomus saccharalis (Dodd), Trimorus varicornis (Walker), Trissolcus basalis (Wollaston), Trissolcus belenus (Walker), Trissolcus colemani (Crawford) and Trissolcus flavipes (Thompson). COI barcodes are identified for the first time from B. europaeus and M. bicolora. Each species is illustrated and updated world distributions are provided. Implications for agriculture are discussed.

Platygastroidea is the third largest superfamily of Hymenoptera in terms of the number of described species, exceeded only by Ichneumonoidea and Chalcidoidea. The current number of valid species is ca. 6,500, with a worldwide estimate of about 10,000 (
In the 19th century, several notable experts published on German Platygastroidea. The earliest was Christian Gottfried Nees von Esenbeck, who described dozens of species in Sparasion, Scelio, Platygaster and Teleas (
Since Kieffer, there has not been much research on the Platygastroidea of Germany. The most recent catalogue of German insects (
Scelionid wasps parasitise the eggs of arthropods, including many invasive or noxious pest species (
The current work represents a first update to the German platygastroid fauna within the German Barcode of Life (GBOL) III initiative. As these findings occurred within the first several months of the project, further discoveries are expected over the next three years. Identification of Platygastridae is still underway, as the state of taxonomic disarray in this group is more severe.
We examined recent and historical collections of Scelionidae at the State Museum of Natural History Stuttgart (SMNS). Recent material was collected for earlier stages of the GBOL project or for long-term insect monitoring programmes, generally by Malaise trap. Recently-collected specimens were preserved in 96% ethanol. Specimens collected for the GBOL project had DNA extracted non-destructively with the DNeasy Blood & Tissue Extraction Kit from Qiagen following the updated protocol provided by

Of the two families of Platygastroidea, Scelionidae is better resolved. High-quality revisions and keys are available for many genera of Scelionidae, due to careful attention from professional taxonomists, as well as data regarding ecological and biological aspects. Platygastridae has been somewhat more neglected and, in large genera, such as Platygaster Latreille and Synopeas Förster, better diagnostic tools are needed for accurate species identification. This is the case with some genera of Scelionidae as well, such as Gryon Haliday and Telenomus Haliday. For example, one-hundred-year-old specimens of Telenomus still remain unidentified in the collection of SMNS. As taxonomic issues are resolved, it will become possible to accurately identify material for barcode reference libraries.
Baryconus europaeus and Macroteleia bicolora are here barcoded for the first time. A comparison with existing records in BOLD Systems (https://www.boldsystems.org/) showed no matches to identified material. For the M. bicolora sequences, the highest match (93.62%) was to unidentified specimens from Gabon. The B. europaeus sequence was most similar (97.63%) to unidentified specimens from South Africa. As expected, all Trissolcus sequences matched well (at least 99%) with appropriately identified material.
Based on preliminary data, several species of Probaryconus are found in Germany, but their nomenclature is uncertain, due to the aforementioned taxonomic impediment. Historical Trissolcus specimens remained unidentified in the SMNS collection for 50 to almost 100 years. The oldest of these, T. colemani, was reared from hemipteran eggs in 1932 (Fig.
In addition to the newly-recorded species, Trissolcus species already known from Germany, such as T. cultratus (Mayr), T. semistriatus (Nees von Esenbeck) and T. scutellaris (Thomson), have been repeatedly detected at various locations in Baden-Württemberg. The last checklist of German Scelionidae (
Our results emphasise that much remains to be discovered regarding parasitoid ecosystem services in Germany. Many of the newly-recorded species parasitise the eggs of stink bugs which pose a threat to vegetable and fruit production. As wasp species differ in their host preference and biological control efficacy, accurate identification is an important factor in agroecological studies (
