An illustrated key is provided for the identification of the 20 genera of Microgastrinae so far known to occur in Europe. A brief review of 20 century progress on the group is given. Morphological terms are explained and illustrated, with special reference to the different systems of wing venation employed by past workers on Microgastrinae in Europe, and recommendations are made for future work.

Two European species are recognised and characterised within the traditional species concept, based initially on DNA barcoding but with supporting, although slight and sometimes unreliable, morphological differences. is described and a neotype is designated for Herrich-Schäffer, 1838. Specimens from the Russian Far East were also DNA barcoded and were found to belong to a new species distinct from the two European taxa.

Substantial parts of the European and German insect fauna still remain largely unexplored, the so-called "dark taxa". In particular, midges (Diptera) and parasitoid wasps (Hymenoptera) are abundant and species-rich throughout Europe, yet are often neglected in biodiversity research. One such dark taxon is Microgastrinae wasps (Hymenoptera: Braconidae), a group of parasitoids of lepidopteran caterpillars with 252 species reported in Germany so far.

The parasitoid wasp genus Mason, 1981 is revised, based on a combination of basic morphology (dichotomous key and brief diagnostic descriptions), DNA barcoding, biology (host data and wasp cocoons), and distribution data. A total of 49 species is considered; the genus is almost entirely Neotropical (48 species recorded from that region), but three species reach the Nearctic, with one of them extending as far north as 45° N in Canada. parasitizes exclusively Hesperiinae caterpillars (Lepidoptera: Hesperiidae), mostly feeding on monocots in the families Arecaceae, Bromeliaceae, Cannaceae, Commelinaceae, Heliconiaceae, and Poaceae.

With more than 633 species, Apanteles is the largest genus within the subfamily Microgastrinae (Hymenoptera, Braconidae). We describe three new species reared from pests of commercial fruits, Apanteles ahuacatl Shimbori, Giacomelli & Fernández-Triana sp. n.

A new species of the rarely collected neotropical microgastrine braconid wasp genus Nixon, represented previously by only a single described species, Nixon, was recovered by the Caterpillars and Parasitoids of the Eastern Andes in Ecuador inventory project. was reared from an unidentified species of arctiine Erebidae feeding on the common bamboo species Kunth at the Yanayacu Biological Station near Cosanga, Napo Province, Ecuador. The new species is described and diagnosed from using both morphological and DNA barcode data.

Article Synopsis
  • Mitochondrial (mt) nucleotide sequences have been key in studying evolutionary relationships, providing insights into both shallow and deep evolutionary scales, particularly in the parasitoid wasp family Braconidae.
  • The study analyzed 148 mt genomes (132 newly generated) to explore evolutionary links and assess the phylogenetic informativeness of existing and new mt gene rearrangements.
  • Findings confirmed most subfamilial relationships consistent with prior studies while revealing both known and novel mt gene rearrangements, indicating that mt genome data is useful for understanding Braconidae evolution at various taxonomic levels.

The parasitoid lifestyle is largely regarded as a key innovation that contributed to the evolutionary success and extreme species richness of the order Hymenoptera. Understanding the phylogenetic history of hyperdiverse parasitoid groups is a fundamental step in elucidating the evolution of biological traits linked to parasitoidism. We used a genomic-scale dataset based on ultra-conserved elements and the most comprehensive taxon sampling to date to estimate the evolutionary relationships of Braconidae, the second largest family of Hymenoptera.

Parapanteles Ashmead (Braconidae: Microgastrinae) is a medium-sized genus of microgastrine wasps that was erected over a century ago and lacks a unique synapomorphic character, and its monophyly has not been tested by any means. Parapanteles usually are parasitoids of large, unconcealed caterpillars (macrolepidoptera) and have been reared from an unusually large diversity of hosts for a relatively small microgastrine genus. We used Cytochrome Oxidase I sequences ("DNA barcodes") available for Parapanteles and other microgastrines to sample the generic diversity of described and undescribed species currently placed in Parapanteles, and then sequenced four additional genes for this subsample (wingless, elongation factor 1-alpha, ribosomal subunit 28s, and NADH dehydrogenase subunit 1).

The descriptive taxonomic study reported here is focused on , a species-rich genus of hymenopteran parasitoid wasps. The species were found within the framework of two independent long-term Neotropical caterpillar rearing projects: northwestern Costa Rica (Área de Conservación Guanacaste, ACG) and eastern Andes, Ecuador (centered on Yanayacu Biological Station, YBS). One hundred thirty-six new species of Ashmead are described and all of them are authored by Arias-Penna.

The first species of (Hymenoptera: Braconidae, Microgastrinae) with the second mediotergite broadly quadrate to rectangular are revised, and eight new species from Area de Conservación Guanacaste (ACG), Costa Rica are described, all authored by Fernandez-Triana & Boudreault: , , , , , , , and . A new species group () within the genus is proposed to accommodate those species, as well as additional undescribed species from the Neotropical region found in collections. All new species are found in rainforests (120-900 m) and all are parasitoids of Depressariidae (except for one species parasitizing Choreutidae).

Ten new species within four genera of Microgastrinae parasitoid wasps (Hymenoptera: Braconidae) are described from Canada and United States: , , , , , , , , , and . The new taxa are significant because they represent the first North American records of a tropical group (species of the group in ), exemplify interesting ecological cases (niche-based host selection in , syntopic species in ), and showcase unique morphological features and/or altitudinal records (). Most of the new species were collected in protected areas or areas with strong research programs (Archbold Biological Station and hammock forests near Miami, Florida; Great Sand Dunes National Park and Preserve, and Mount Evans Wilderness Area, Colorado; Sapelo Island, Georgia; Tonto National Forest, Arizona), and thus are also of value and interest for conservation and research efforts.

The braconid parasitoid wasp subfamily Microgastrinae is perhaps the most species-rich subfamily of animals on Earth. Despite their small size, they are familiar to agriculturalists and field ecologists alike as one of the principal groups of natural enemies of caterpillars feeding on plants. Their abundance and nearly ubiquitous terrestrial distribution, their intricate interactions with host insects, and their historical association with mutualistic polydnaviruses have all contributed to Microgastrinae becoming a key group of organisms for studying parasitism, parasitoid genomics, and mating biology.

Many parasitoid species are subjected to strong selective pressures from their host, and their adaptive response may result in the formation of genetically differentiated populations, called host races. When environmental factors and reproduction traits prevent gene flow, host races become distinct species. Such a process has recently been documented within the species complex, all of which are larval parasitoids of moth species whose larvae are stem borers of Poales.
