Advances in the Systematics of Platygastroidea III builds on the foundation laid by its
predecessors, presenting 17 articles authored by a diverse group of researchers. Like
previous installments, these articles cover several active areas of platygastroid research
including alpha and integrative taxonomy, paleontology, phylogenetics, morphology,
and biological control.

Studies on Platygastridae comprise the first four papers. Awad et al. (2021) raise
the bar for taxonomy in the subfamily Platygastrinae with their description of 16
new species of Synopeas from New Guinea in an integrative framework that includes
plant associations and DNA barcoding. Talamas et al. (2021a) describe a new genus
and species of Platygastridae from Burmese amber, utilizing information from both
fossil and extant taxa. The subfamily Sceliotrachelinae is the subject of two articles
that treat specimens from different continents. Lahey et al. (2021b) revise the Aus-
tralian genus A/fredella and sink a genus that was erected for an apomorphic species of
Amitus. Genus-level treatment of the sceliotracheline fauna of the Afrotropical region
is presented by van Noort et al. (2021), with new species described in four genera,
including revisions of Old World Parabaeus and the South African endemic genera
Afrisolia and Sceliotrachelus.

Advances in imaging technologies have made it possible to non-invasively examine
the internal anatomy of insects. Nowhere is this more valuable than in the study of
fossil taxa for which specimens are often rare and dissections are not possible. Bremer
et al. (2021) describe a new species of the previously monobasic Janzenella, the sole ge-
nus in Janzenellidae, preserved in Baltic amber. Their description utilizes synchrotron
microtomography to visualize external and internal morphological characters that were
otherwise inaccessible. Their analysis of internal structures dovetails with the morpho-
logical exploration of the internal mesosoma by Miko et al. (2021b) that documents
characters that have potential to help classify fossil taxa for which family-level place-
ment is presently unclear.

The second half of this special issue comprises 11 papers on Scelionidae. Two of these
are revisions of tropical genera that result in the description of 17 new species (Lahey et
al. 2021a; Mik6 et al. 2021a). The treatment of Oxyscelio by Mo et al. (2021) expands the
known diversity of the Chinese fauna with a combined analysis of morphology and COI
barcode data. ‘The global importance of stink bugs and their associated parasitoids is evi-
denced by the remaining eight papers. ‘These include molecular phylogenetic studies that
result in the synonymy of Latonius under Trissolcus (Vasilita et al. 2021); the resurrection
of Hadronotus for a portion of Gryon (Talamas et al. 2021b); the discovery of adventive
parasitoids on two continents (Birkmire et al. 2021; Hogg et al. 2021; Rojas-Galvez et
al. 2021); interbreeding studies between populations of a new Gryon species (Hogg et al.
2021); a new, medically-important host association for Telenomus fariai (Ramirez-Ahuja
et al. 2021); the description of a new species of Trissolcus from Iran (Ranjbar et al. 2021);
and an analysis of chemoreceptor genes from Trissolcus basalis (King et al. 2021).

The increased number of papers in this special issue reflects the growing number
of workers in Platygastroidea, which have historically been few in number. Impor-
tantly, it also reflects cooperation on a global level, with contributing authors from all
inhabited continents.
