The Chalcidoidea bush of life: evolutionary history of a massive radiation of minute wasps.

Chalcidoidea are mostly parasitoid wasps that include as many as 500 000 estimated species. Capturing phylogenetic signal from such a massive radiation can be daunting. Chalcidoidea is an excellent example of a hyperdiverse group that has remained recalcitrant to phylogenetic resolution.

Mischochalcis, an enigmatic new genus of Chalcididae (Hymenoptera: Chalcidoidea) from the Old World tropics with the description of a new species.

A new chalcidid genus, Mischochalcis (Hymenoptera: Chalcididae), is erected with the description M. enigmatus sp. nov.

Ultra-Conserved Elements and morphology reciprocally illuminate conflicting phylogenetic hypotheses in Chalcididae (Hymenoptera, Chalcidoidea).

Recent technical advances combined with novel computational approaches have promised the acceleration of our understanding of the tree of life. However, when it comes to hyperdiverse and poorly known groups of invertebrates, studies are still scarce. As published phylogenies will be rarely challenged by future taxonomists, careful attention must be paid to potential analytical bias.

Description of Eniacomorpha hermetiae Delvare sp. n. (Hymenoptera, Chalcidoidea, Chalcididae) a pupal parasitoid of Hermetia illucens (L.) (Diptera, Stratiomyidae), and a potential threat to mass production of the fly as a feed supplement for domestic animals.

Eniacomorpha hermetiae Delvare sp. n. (Hymenoptera, Chalcididae, Dirhininae), reared from pupae of black soldier fly (BSF), Hermetia illucens (Linnaeus, 1758) (Diptera, Stratiomyidae), is described and illustrated from Africa and compared with other similar species newly considered as forming the ehrhorni species-group within Eniacomorpha Girault, 1915.

Deciphering host-parasitoid interactions and parasitism rates of crop pests using DNA metabarcoding.

An accurate estimation of parasitism rates and diversity of parasitoids of crop insect pests is a prerequisite for exploring processes leading to efficient natural biocontrol. Traditional methods such as rearing have been often limited by taxonomic identification, insect mortality and intensive work, but the advent of high-throughput sequencing (HTS) techniques, such as DNA metabarcoding, is increasingly seen as a reliable and powerful alternative approach. Little has been done to explore the benefits of such an approach for estimating parasitism rates and parasitoid diversity in an agricultural context.

Torymidae (Hymenoptera, Chalcidoidea) revised: molecular phylogeny, circumscription and reclassification of the family with discussion of its biogeography and evolution of life-history traits.

A phylogeny of the Torymidae (Chalcidoidea) is estimated using 4734 nucleotides from five genes. Twelve outgroups and 235 ingroup taxa are used, representing about 70% of the recognized genera. Our analyses do not recover Torymidae as monophyletic and we recognize instead two families: Megastigmidae (stat.

Review of Iranian Chalcididae (Hymenoptera, Chalcidoidea) with nomenclatural notes.

The current paper presents new data on the nomenclature and distribution of Chalcididae (Hymenoptera, Chalcidoidea) collected in various regions of Iran. The following new synonymies are proposed: Brachymeria argenteopilosa (Radoszkowski, 1876) = Chalcis persica Masi, 1824 syn. nov.

The subfamily Cratocentrinae (Hymenoptera: Chalcididae): reappraisal of their morphological characters and review of the West Palaearctic species, with the description of two new species.

The Cratocentrinae (Hymenoptera: Chalcididae) of the West Palaearctic region are reviewed. A reappraisal of the morphological characters used for their recognition and phylogeny is provided as is a key to separate the genera and species of the region. Their distribution in the West Palaearctic is updated and the subfamily is reported for the first time in Europe.

Four-horned wasps, description of some remarkable Dirhinus (Hymenoptera, Chalcididae) from Kenya, with a discussion of their taxonomic placement.

Five new species belonging to Dirhinus Dalman are described: D. quadrhinus Delvare sp. nov.

Description of sp. n. (Hymenoptera: Chalcididae), a parasitoid of the bird parasite (Diptera: Muscidae) in Tobago, with a review of the sibling species.

In this paper, we describe and illustrate a new species of parasitoid wasp as Brachymeria philornisae Delvare, sp. nov. The new species was reared from Philornis trinitensis Dodge & Aitken (Diptera: Muscidae) puparia that were found in the nests of the bird species Mimus gilvus (Vieillot) (Mimidae) and Tiaris bicolor (L.

Investigating Biological Control Agents for Controlling Invasive Populations of the Mealybug Pseudococcus comstocki in France.

Pseudococcus comstocki (Hemiptera: Pseudococcidae) is a mealybug species native to Eastern Asia and present as an invasive pest in northern Italy and southern France since the start of the century. It infests apple and pear trees, grapevines and some ornamental trees. Biocontrol programmes against this pest proved successful in central Asia and North America in the second half of the 20th century.

Availability of eleven species names of Eupelmus (Hymenoptera, Eupelmidae) proposed in Al khatib et al. (2014).

This paper is an addendum for the availability of the names of 11 new species proposed in Al khatib et al. (2014).

A phylogenetic analysis of the megadiverse Chalcidoidea (Hymenoptera).

Chalcidoidea (Hymenoptera) is extremely diverse with an estimated 500 000 species. We present the first phylogenetic analysis of the superfamily based on both morphological and molecular data. A web-based, systematics workbench mx was used to score 945 character states illustrated by 648 figures for 233 morphological characters for a total of 66 645 observations for 300 taxa.
