Neocardiochiles Szépligeti, 1908, is a rare Neotropical genus of the subfamily Cardiochilinae Ashmead, 1900. The genus was previously synonymized with Heteropteron Brullé, 1846 by Dangerfield et al. (1999). In this study, we examined multiple specimens of Heteropteron-related genera: Heteropteron, Neocardiochiles, and Wesmaelella Spinola, 1851, and...

Microplitis Foerster is a highly diverse and cosmopolitan genus within Microgastrinae (Hymenoptera, Ichneumonoidea, Braconidae). Microplitis ceratomiae Riley, a widely distributed North American species, exclusively attacks sphingid caterpillars. In this paper, M. ceratomiae is reported parasitizing a caterpillar of Sphinx poecila Stephens (Sphingi...

Aximopsis gabrielae Zhang, Gates and Campos sp. nov. is described from southern Mexico in the Yucatan Peninsula, Mexico. This species is a koinobiont gregarious larval-pupal endoparasitoid of the caterpillar of Quadrus cerialis (Stoll) (Lepidoptera: Hesperiidae) feeding on the shrub Piper amalago L. (Piperaceae) in the semievergreen forest. This is...
Article
Miracinae are a small subfamily of parasitoid wasps that are under‐represented in collections and that have yet to be formally recorded from Australia. Bayesian and maximum likelihood phylogenetic analyses were performed using the barcoding region of cytochrome c oxidase subunit I (COI) from 11 miracine specimens collected throughout Australia, alo...
Article
The investigation of endogenous viral elements (EVEs) has historically focused on only a few lineages of parasitoid wasps, with negative results consistently underreported. Recent studies show that multiple viral lineages were integrated in at least seven instances in Ichneumonoidea and may be much more widespread than previously thought. Increasin...
Article
A new genus of the braconid wasp tribe Cedriini, Sagarana n. gen., (Hymenoptera, Braconidae) is described and illustrated from the Brazilian cerrado based on a newly discovered species, Sagarana cerradensis n. sp. The genus is clearly distinct from the other genera of the Cedriini, with unusual fringed depressions on the second metasomal sternite t...

en Natural history studies documenting spatial and temporal variation of species assemblages and their interactions are critical for understanding biodiversity and community ecology. We characterized caterpillar–parasitoid assemblages on shrubs in the genus Piper across remnants of semi‐evergreen forest in the Yucatán Península during the rainy and...

Endogenous viruses form an important proportion of eukaryote genomes and a source of novel functions. How large DNA viruses integrated into a genome evolve when they confer a benefit to their host, however, remains unknown. Bracoviruses are essential for the parasitism success of parasitoid wasps, into whose genomes they integrated~103 million year...

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 u...

Most endogenous viruses, an important proportion of eukaryote genomes, are doomed to slowly decay. Little is known, however, on how they evolve when they confer a benefit to their host. Bracoviruses are essential for the parasitism success of parasitoid wasps, whose genomes they integrated ~103 million years ago. Here we show, from the assembly of...

Extreme weather events dramatically impact populations of individual insect species but the consequences of such events for entire insect communities are not well documented. We present evidence that mid spring frosts and summer drought negatively affect the community of insects found on Missouri oaks (Quercus alba and Q. velutina), amounting to a...

Only rarely have bumble bees ( Bombus ) been observed collecting honeydew from aphids (Aphididae) feeding on phloem sap. This behavior may be rare because the percentage of sugar in honeydew egested from aphids is generally well below the sugar concentration in floral nectars preferred by bumble bees. Nonetheless, in August 2018, near St. Buryan, P...

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 distri...

Species tree reconstruction from genome-wide data is increasingly being attempted, in most cases using a two-step approach of first estimating individual gene trees and then summarizing them to obtain a species tree. The accuracy of this approach, which promises to account for gene tree discordance, depends on the quality of the inferred gene trees...

Phylogenomics has ushered in an age of discordance. Analyses often reveal abundant discordances among phylo- genies of different parts of genomes, as well as incongruences between species trees obtained using different methods or data partitions. Researchers are often left trying to make sense of such incongruences. Interpretive ways of measur- ing...
