They are often host‐specific and thus are extensively used in biological control efforts and figure prominently in trophic webs. However, their extraordinary diversity coupled with the occurrence of many cryptic species produces a significant taxonomic impediment. We present and release the results of 8 years (2004–2011) of DNA barcoding microgastrine wasps. Currently they are the best represented group of parasitoid Hymenoptera in the Barcode of Life Data System (BOLD), a massive barcode storage and analysis data management site for the International Barcoding of Life (iBOL) program. There are records from more than 20 000 specimens from 75 countries, including 50 genera (90% of the known total) and more than 1700 species (as indicated by Barcode Index Numbers and 2% MOTU). We briefly discuss the importance of this DNA data set and its collateral information for future resear...

(type species Rhytidaphora thailandica Reshchikov & Quicke gen. et sp. nov.) from Thailand is described and illustrated. It belongs to the tribe Euryproctini of the subfamily Ctenopelmatinae (Hymenoptera, Ichneumonidae) based on the absence of glymma and the subapical notch on the ovipositor. The new taxon differs from all other genera of Euryproctini by the occipital carina being broadly incomplete dorsally, the hypostomal carina joining the occipital carina shortly before the base of the mandible, distinctly pectinate tarsal claws, and immovably fused and strongly sculptured second and third metasomal tergites.

Here we report that Y. iranus is a parasitoid of caterpillars of the pyralid moth Phycita diaphana in Israel, the first host record for the genus from outside of the Americas. We illustrate the wasp's mummified host, emergence hole and the wasp's own cocoon which is constructed within the tanned mummified host remains. We hypothesize that a physiological or behavioural association of Yelicones parasitoids with the Pyralidae commenced at least during the early Miocene (ca. 16 Mya).

(Hymenoptera: Braconidae: Rogadinae) from Australia (New South Wales) is described, illustrated and distinguished from other members of the subgenus. It is the second species of the subgenus known from Australia to date, and on the basis of its morphology is most closely related to Aleiodes (H.) ellingsenae Butcher & Quicke from Tasmania. The previously unknown female of A. (H.) glandularis Butcher & Quicke from South Africa is also briefly described and illustrated.

They are plant feeders and have six developmental stages. The sessile puparia stage is used to identify whiteflies and can provide useful host-plant identity. The general aim of this study is to redefine the subfamily Aleurodicinae by addressing its distribution and phylogenetic relationships. Approximately 88% of Aleurodicinae species are neotropical, though six genera, Aleuroctarthrus, Palaealeurodicus, Nipaleyrodes, Pseudosyaleurodicus, Synaleurodicus and Stenaleyrodes, are mostly distributed in the Australasian region. The separation of Australia from the Southern Gondwanan land mass may explain the Australasian distribution. Twentyseven percent of species are polyphagous but few species are recorded in three or more regions. Aleurodicus dispersus, Paraleyrodes minei and P. bondari are considered invasive pests. Regional proximity coupled with the anthropogenic effects are the main factors responsible for the shared species. In general, polyphagous species are more likely to suffer parasitism and are generally the subject of biological control. Dirphys, a neotropical genus of aleurodicinae, has potential as a bio-control agent. Phylogenetic relationships were assessed using 65 DNA sequences derived from members of nine aleurodicine genera and from 30 adult whitefly species, and puparial morphological characters were derived from 76% of described aleurodicine species and an additional nine out-groups. From morphological data, the strict consensus (length 182, CI=0.189 and RI=0.649) of unweighted most parsimonious trees, Aleurodicinae was recovered as non-monophyletic with some, mainly Australasian genera, being placed among the out-group taxa. Under the implied weighting algorithm and with the concavity factor K ≥ 6, Aleurodicinae was, however, monophyletic. A similar relationship occurred with the molecular analysis in the absence of those Australasian genera. Twelve valid monophyletic genera were recognized, with Dialeurodicus forming the sister group to the remaining genera. Three pairs of sister genera were indicated and one pair, Bakerius plus Leornadius was synonymized. Some intrageneric relationships were supported while some species formed sibling relationships, for example Aleurodicus pulvinatus, A. cocois and A. juleikae form a subclade within the genus. Some generic groups need restructuring, for example, Metaleurodicus.

Correlation and regression analyses are used to test whether, and to what degree, variation in one continuous variable is related to variation in another continuous variable. In correlation analysis, there are no control over either variable, they are just data collected, and indeed, even if two variables are strongly correlated, they may not be influencing one another but simply both being affected by a third which perhaps was not measured. The initial assumption of the analysis is that the values of both variables are drawn from a normal distribution. In regression analysis one of the variables are being controlled seeing whether changing its value affects the other. The variable being controlled is the explanatory variable (sometimes called the treatment) and the other is the response variable. As the explanatory variables are being controlled, they are probably going to be set at specified values or set increments and ...

The very large wasp superfamily Ichneumonoidea is composed of parasitoids of other insects and comprises a minimum of 100,000 species. The superfamily is dominated by two similarly sized families, Braconidae and Ichneumonidae, which are collectively divided into approximately 80 subfamilies. Of these, six have been shown to release DNA-containing virus-like particles, encoded within the wasp genome, classified in the virus family Polydnaviridae. Polydnaviruses infect and have profound effects on host physiology in conjunction with various venom and ovarial secretions, and have attracted an immense amount of research interest. Physiological interactions between the remaining ichneumonoids and their hosts result from adult venom gland secretions and in some cases, ovar...

The "planatus" form is shown to be the teneral (unhardened) version of the "ventricosus" form. The following synonymies are proposed: Scambus calobatus (Gravenhorst, 1829) = S. planatus (Hartig, 1838), syn. n. = S. ventricosus (Tschek, 1871), syn. n. Molecular data point to incidental natural rearings of a further two species, represented by single specimens.

Two other new species without biological data are also described, C. nicolepeelerae Quicke & Butcher sp. n. also from Papua New Guinea, and C. kiddo Quicke & Butcher sp. n. from Thailand. A key is provided to the four known species. The new species extend the known range of the genus considerably, it having previously been known only from a single species from mainland China (Yunnan), and additionally provides the first host record for the genus. Other related genera are parasitoids of Sphingidae, Lymantriidae and Crambidae.

Here I show that for both braconid and ichneumonid wasps there are highly significant relationships between body size and the mean recorded latitude of species. Numbers of species per genus (surrogates of clades) peaks in the temperate zone for both families contrasting with data from the virtually complete inventories for mammals, birds and monocot plants, suggesting massive under-description of tropical parasitoid faunas. If the ichneumonoids may be expected to show similar trends to mammals, birds and other groups, the implication is that taxonomic work both in terms of active generic revisions, but also likely, the collecting and processing of museum specimens, and selection of taxa for revision, is woefully inadequate to allow latitudinal patterns in biology to be analysed.

The genera Megagonia Szipligeti and Holcosomius Fahringer are synonymized with Zaglyptogastra. Goniobracon Szfpligeti and Euryacria Enderlein are synonymized with Bathyaulax, and the relationship of the latter to Ischnobracon Baltazar is discussed. The genera Antiolcia Enderlein, Diamblomcrina Enderlein and Bias tomorpha Cameron are synonymized with Odontoscapus. The type specimens of twenty-nine species of braconines have been examined; ten of these are transferred to Zaglyptogastra, seven to Bathyaulax and seven to Odontoscapus. The generic position of five species originally described as belonging to Bathyaulax has been confirmed.

The results support a morphology-based phylogeny, presented elsewhere, with Yelicones being divided into two major groups corresponding to the New and Old World faunas. The African and Asian species largely form separate clades except for Yelicones wui Chen & He from China which is associated with the Afrotropical species. Potential molecular synapomorphies are illustrated.

Several estimation methods have previously been described and discussed in some detail, but the reliability of these methods is difficult to assess. In this study, we use two independent methods to predict the global species richness of the subfamilies of the parasitic wasp family Braconidae. The first is to extrapolate from the decreasing rate of species descriptions to the point at which this rate reaches zero. The second method uses the geographical distribution of species in two well-studied taxa (butterflies and mammals) to extrapolate from our knowledge of braconid diversity in the Palaearctic. For the subfamilies which currently contain at least 50 species, there is a significant correlation between the proportions of undescribed species predicted by each method. Each method predicts an average increase of between 100% and 200% for the Braconidae as a whole. Applying the figures we obtain to the class Insecta yields an estimate of 2.05-3.4 million global insect species.
