Despite the significance of the Galapagos archipelago, the richness of diverse groups such as braconid wasps remains poorly studied. Seven species of chelonine Braconidae are recorded for the Galapagos islands for the first time: Chelonus buscki Viereck, 1912, Chelonus carinatus Provancher, 1881, Chelonus johni Marsh, 1979, Chelonus refluus (Papp,...

Parasitoid wasps are exceptionally diverse and use specialized adaptations capable of manipulating the physiology and behaviour of host organisms¹. In more than two centuries since the first records of Drosophila-parasitizing wasps, nearly 200 described and provisional parasitoid species of drosophilids have been identified². These include endopara...

A new species of Aleiodes Wesmael in the gastritor Thunberg species-group is described and illustrated. The new species, Aleiodes ceres Shimbori sp.n. , occurs in Southern Brazil and Argentina. It is a potential biological control agent of caterpillars in the genus Spodoptera Guenée, namely S. cosmioides (Walker), S. eridania (Stoll), and S. frugip...

The parasitoid wasp genus Alphomelon 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),...

The endemic Afrotropical genus Dinapsis is revised, and seven new species are described and illustrated: D. bicolor van Noort & Shaw, sp. nov. , D. gamka van Noort & Shaw, sp. nov. , D. igneus van Noort & Shaw, sp. nov. , D. spinitibia van Noort & Shaw, sp. nov. , D. taita van Noort & Shaw, sp. nov. , D. tricolor Shaw & van Noort, sp. nov. , D. zul...

An updated comprehensive list of the Middle East species of the subfamily Aphidiinae is provided. The fauna of the Middle East countries comprises 111 Aphidiinae species in 18 genera and three tribes (Aphidiini Haliday, 1833, Ephedrini Mackauer, 1961; Praini Mackauer, 1961). The aphidiine species of the present checklist are reported from 14 countr...

Parasitoids are among the most diverse and important enemies of caterpillars. They are key components of the multitrophic communities in which caterpillars are sandwiched, and they have played a profound role in shaping caterpillar morphology, ecology, physiology, and behavior. Here, we review the natural histories and ecologies found in major para...

Megalyridae is a small family of mostly Southern Hemisphere parasitoid wasps, with the females of some species having ovipositors up to eight times their body length. The largest genus, Megalyra, is represented by 22 Australian species. Despite the conspicuous morphology of females, the biology of this family is relatively poorly known, with few pu...

The latest, most comprehensive, knowledge of the parasitoid wasps of the family Braconidae is provided for Middle Eastern countries. It comprises the systematics, biology, biological control benefits, as well as the distribution of braconid species both globally and in the Middle East. An illustrated key to braconid subfamilies known to occur in th...

Phytophagy has promoted species diversification in many insect groups, including Hymenoptera, one of the most diverse animal orders on Earth. In the predominantly parasitoid family Braconidae, an association with insect-induced, plant galls in angiosperms have been reported in three subfamilies, but in particular in the Doryctinae, where it has bee...

A molecular phylogeny of the subfamily Rogadinae is presented for 469 species in 52 genera representing all tribes and subtribes. The data comprise cytochrome c oxidase I sequences (DNA barcodes), together with a broad representation of 28S rDNA D2-D3 expansion region, EF1-α gene and 16S rDNA fragments. To test monophyly, most genera were represent...

Three new genera are described: Michener (Proteropinae), Bioalfa (Rogadinae), and Hermosomastax (Rogadinae). Keys are given for the New World genera of the following braconid subfamilies: Agathidinae, Braconinae, Cheloninae, Homolobinae, Hormiinae, Ichneutinae, Macrocentrinae, Orgilinae, Proteropinae, Rhysipolinae, and Rogadinae. In these subfamili...

Two new species of Bohayella Belokobylskij, 1987 from Costa Rica are described: Bohayella geraldinae Kang, sp. nov. and Bohayella hansoni Kang, sp. nov. These are new distribution records for the genus in the Neotropical region. In addition, a key to species of the genus Bohayella of Costa Rica is presented. The current work elevates the number of...

Five new species, Dinapsis albicauda, n. sp., D. cresta, n. sp., D. luteus, n. sp., D. planifrons, n. sp., and D. scriptus, n. sp. are described from the island of Madagascar. The Dinapsis hirtipes species-group is proposed based on D. hirtipes Hedqvist, 1967 and the five newly described species. A key to species of the D. hirtipes species-group is...

The Aleiodes bakeri (Brues) species subgroup of the A. seriatus species group is defined based on two previously described species, A. bakeri and A. nigristemmaticum (Enderlein), and is greatly expanded in this paper with an identification key, descriptions, and illustrations of 18 new species from the Neotropical Region: A. andinus Shaw & Shimbori...

The genus Vipio Latreille is revised for the Neotropical region (south of Nicaragua). All species are fully illustrated. Thirteen species are recognised of which five ( V. boliviensis , V. carinatus , V. godoyi , V. hansoni , and V. lavignei ) are described as new, all with descriptions attributable to Inayatullah, Shaw & Quicke. All previously des...

The genus Megalyra Westwood, commonly referred to as “long-tailed wasps,” is represented by 27 extant species. Regarded as a parasitoid of xylophagous beetles, Megalyra species are mostly native to the Australasian region; however, one species occurs naturally in Malaysia and Sumatra, and another has been reported as accidentally introduced into So...

Species of adeliine braconids were previously described and named from all biogeographic areas of the world except the Neotropical Region. Here we present the first taxonomic revision of New World adeliines, as well as the first newly de- scribed species of both genera, Adelius and Paradelius, from the Neotropical Region. Although not commonly samp...

The genus Leptodrepana Shaw was described in 1983, but prior to the current study only one Neotropical species had been described from Mexico and none were named from Costa Rica. In this paper twenty-four new species are described and named from Costa Rica: L.alexisae Dadelahi & Shaw, sp. n. , L.atalanta Dadelahi & Shaw, sp. n. , L.conda Dadelahi &...

1. Many tropical organisms have narrow altitudinal ranges and therefore may be especially vulnerable to climate change. Parasitoid wasps are no exception, so baseline knowledge about their vulnerability to rising temperatures needs to include analyses of their distributional ranges along elevational gradients. 2. Using museum collections of the par...

Four new species of the Aleiodes apicalis (Brullé) species group (Hymenoptera: Braconidae: Rogadinae) from the Neotropical Region are described and illustrated: Aleiodes ambrosiaenew species . from Peru, A. aquilesinew species from Costa Rica, and A. sachambrosiaenew species and A. tapirapenew species from Brazil. We also add new distribution recor...

Mesostoinae is a poorly understood subfamily, with a classic Gondwanan distribution. Historically, its members have been classified in as many as nine different subfamilies and/or tribes. Formally comprising seven genera (Andesipolis, Aspilodemon, Hydrangeocola, Opiopterus, Mesostoa, Praonopterus and Proavga), there are at least six more genera (Ap...

Orionis is a small Neotropical euphorine genus, currently in the tribe Perilitini. Although the biology of the genus is unknown, Orionis eximius (Muesebeck) was described from a single female specimen reared from a cocoon associated with Lantana camara. Here, we present a taxonomic revision of Orionis and the first records of the genus from South A...

A cocoon attached to the body of an adult weevil of the family Ithyceridae in Burmese am- ber was identified as a member of the subfamily Euphorinae Foerster, 1862 of the family Braconidae. This discovery represents an early record of adult-insect parasitism (imagobiosis) by Hymenoptera and indicates that weevils are ancient hosts of euphorine brac...

The neotropical genus Athacryvac Braet & van Achterberg was recently described based on two species from French Guiana. Despite the resemblance of these species with the diverse and widespread genus Aleiodes, the authors opted to erect the new genus based on several synapomorphies. With the analysis of more comprehensive morphological and geographi...

In the Ecuadorian cloud forest, males of the parasitoid braconid wasp Napo townsendi Shaw displayed facultative lekking, appearing both singly and in groups of 2–7 on the leaf tops of various plant species. To attract females, they constantly employed a stereotypical, spread-winged calling behaviour, apparently releasing a sex pheromone combed from...
