Platystethynium (Platypatasson) earlyi Huber, sp. n. (Hymenoptera: Mymaridae), is described from both sexes reared from an egg of Rhaphidophoridae (Orthoptera) found in an old mining tunnel in New Zealand. The male is micropterous and has lateral ocelli but no median ocellus, a unique feature in Mymaridae found so far only in males of Platystethynium Ogloblin species. The remaining described Eastern Hemisphere species of Platystethynium are discussed and Platystethynium glabrum Jin & Li, syn. n., is placed in synonymy under P. onomarchicidum Ogloblin. A key to females, and males where known, of the described Eastern Hemisphere species of Platystethynium is given.

Separate identification keys for females, and for males where known, of the 40 genera of Mymaridae (Hymenoptera: Chalcidoidea) in the Afrotropical region are given. The subgenera of four genera are also included in the key to females. The genera are illustrated with over 300 photographs. The 122 named, valid species reported from the region are catalogued. Reliable host records are reported for 6 genera and 11 species from rearings undertaken in the region. An appendix lists the 27 species from northern Africa and offshore islands (Canary Islands, Madeira) but not recorded in the Afrotropical region as defined in this publication. Camptoptera (Zemicamptoptera) Ogloblin & Annecke, syn. n. is synonymized with Camptoptera (Camptoptera) Foerster. Eofoersteria Mathot, syn. n. is synonymized with Camptoptera Foerster and is treated as subgenus C. (Eofoersteria) Mathot, stat. n.; its type species Eofoersteria camptopteroides Mathot is transferred to Camptoptera as C. (Eofoersteria) camptopteroides (Mathot), comb. n. Polynema megacephala (Risbec) is transferred to Lymaenon as L. megacephala (Risbec), comb. n. Limacis opuntiae Risbec is transferred to Encarsia Foerster (Hymenoptera: Aphelinidae) as E. opuntiae (Risbec), comb. n. A few corrections to Huber et al. (2020) are given.

Capturing phylogenetic signal from a massive radiation can be daunting. The superfamily Chalcidoidea is an excellent example of a hyperdiverse group that has remained recalcitrant to phylogenetic resolution. Chalcidoidea are mostly parasitoid wasps that until now included 27 families, 87 subfamilies and as many as 500,000 estimated species. We combined 1007 exons obtained with Anchored Hybrid Enrichment with 1048 Ultra-Conserved Elements (UCEs) for 433 taxa including all extant families, over 95% of all subfamilies and 356 genera chosen to represent the vast diversity of the superfamily. Going back and forth between molecular results and our collective morphological and biological knowledge, we detected insidious bias driven by the saturation of nucleotide data and highlighted morphological convergences. Our final results are based on a concatenated analysis of the least saturated exons and UCE data sets (2054 loci, 284,106 sites). Our analyses support a sister relationship with Mymarommatoidea. Seven of the previously recognized families were not monophyletic, so foundations for a new classification are discussed. Biology appears potentially more informative than morphology, as illustrated by the elucidation of a clade of plant gall associates and a clade of taxa with planidial first-instar larvae. The phylogeny suggests a shift from smaller soft-bodied wasps to larger and more heavily sclerotized wasps. Deep divergences in Chalcidoidea coincide with an increase in insect families in the fossil record, and an early shift to phytophagy corresponds with the beginning of the “Angiosperm Terrestrial Revolution”. Our dating analyses suggest a Middle Jurassic origin of 174 Ma (167.3-180.5 Ma) and a crown age of 162.2 Ma (153.9–169.8 Ma) for Chalcidoidea. During the Cretaceous, Chalcidoidea underwent a rapid radiation in southern Gondwana with subsequent dispersals to the Northern Hemisphere. This scenario is discussed with regard to knowledge about host taxa of chalcid wasps, their fossil record, and Earth’s paleogeographic history.

A checklist of 1246 extant, described species, classified in 346 genera in 18 families of Chalcidoidea (Hymenoptera) are reported from Canada, Alaska (USA) and Greenland (Denmark) based on examined specimens and published records up to December 31, 2020. Of the reported species, 1214 (in 345 genera in 18 families) are listed from Canada, 113 (in 58 genera in 10 families) from Alaska, and 26 (in 22 genera in 4 families) from Greenland. The list includes 235 new species records and 53 new generic records for Canada (no new family records). Forty-one new species records, 22 new generic records and the families Chalcididae and Eurytomidae are newly reported for Alaska. No new records were found for Greenland. Two species (in one genus) of Mymarommatoidea are reported from Canada. For each species in Canada, distribution is tabulated by province or territory, except the province of Newfoundland and Labrador is divided into the island of Newfoundland and the region of Labrador. The inclusion of known species from Alaska and Greenland results in the first comprehensive distributional checklist for the entire northern part of the Nearctic region. A brief review of the history of cataloguing Chalcidoidea in North America and a comparison of this checklist with four published checklists from the Palaearctic region is provided.

Tanyxiphium longissimum Huber, syn. n. (Hymenoptera: Mymaridae) is synonymized under T. harriet (Zeya) based on examination of specimens from Hainan Island and Yunnan Province in the Oriental part of China, Sulawesi Island in Indonesia, Peninsular Malaysia, and Thailand. These are new country distribution records except for Thailand. The previously unknown male of T. harriet is described from Sulawesi Island, and the female is redescribed and illustrated based on non-type material examined.

An overview of the Oriental species of the nominate subgenus of Camptopteroides Viggiani (Hymenoptera: Mymaridae) is given. Two new species, C. (Camptopteroides) formosa Manickavasagam & Sankararaman sp. n. from India and C. (Camptopteroides) reducta Triapitsyn sp. n. from Thailand and Malaysia, are described, and C. formosa additionally compared to two unnamed species. The holotype male of the type species of this genus, C. armata Viggiani from Sri Lanka, is diagnosed and illustrated. A key to Old World species of Camptopteroides is provided.

Identification keys for females, and for males where known, to the 39 genera and 11 subgenera of Mymaridae in America north of Mexico are given. The genera are illustrated with over 1010 photographs and/or scanning electron micrographs. The 202 currently named and valid species reported from America north of Mexico are catalogued. Reliable host records are reported for 16 genera and almost 90 species from rearings in the region. The five genera represented by more than one subgenus in the region are: Anagrus Haliday, Anaphes Haliday, Erythmelus Enock, Kalopolynema Ogloblin, and Polynema Haliday. Five other genera are represented only by unnamed and possibly undescribed species. About 1000 literature references, mainly the North American ones, are listed. Three new species are described: Callodicopus floridanus Huber, sp. n., Neostethynium americanum Huber, sp. n., and Stephanocampta xanthogaster Huber, sp. n. Cosmocomoidea marilandica (Girault), stat. rev., is placed in synonymy under C. dolichocerus (Ashmead). Platypatasson Ogloblin is given subgeneric status as Platystethynium (Platypatasson Ogloblin), stat. rev. Corrections and additions to the mymarid fauna of Mexico by Guzmán-Larralde et al. (2017) are also given.

A neotype for Anaphes flavipes (Foerster, 1841) (Hymenoptera: Mymaridae), a biological control agent of Oulema melanopus (Linnaeus, 1758) (Coleoptera: Chrysomelidae), is designated. The extensive literature on A. flavipes is compiled and the morphological variability of selected morphological structures of numerous reared specimens from across its presently known geographic range (mainly eastern Nearctic and western Palearctic) is described. Anaphes flavipes is compared with what appears to be morphologically and biologically the most similar species, A. nipponicus Kuwayama, 1932, from Japan, which is briefly redescribed. Anaphes auripes Walker, 1846, syn. nov., is placed in synonymy under A. flavipes. The following new country and state records for A. flavipes are provided: Czech Republic, Ukraine, Canada (Nova Scotia), USA (Virginia).

Two species of Anaphes Haliday with distinctive females are described from India (A. triapitsyni Anwar & Zeya, sp. nov.) or from India and Indonesia (A. kailashchandrai Anwar & Zeya, sp. nov.). The only other Anaphes species known to occur in India is A. quinquearticulatus Huber & Triapitsyn because previous records of A. pallipes (Ashmead) and A. pullicrurus (Girault) are based on misidentifications. These latter two names are therefore removed from the faunal list of India. An illustrated key to females of the three described species of Anaphes known from India is given. The described species of Anaphes known from Australia are also briefly reviewed, with type material of four previously unillustrated species being newly imaged and compared to the Indian species.

Enriching subsets of the genome prior to sequencing allows focusing effort on regions that are relevant to answer specific questions. As experimental design can be adapted to sequence many samples simultaneously, using such approach also contributes to reduce cost. In the field of ecology and evolution, target enrichment is increasingly used for genotyping of plant and animal species or to better understand the evolutionary history of important lineages through the inference of statistically robust phylogenies. Limitations to routine target enrichment by research laboratories are both the complexity of current protocols and low input DNA quantity. Thus, working with tiny organisms such as micro-arthropods can be challenging. Here, we propose easy to set up optimisations for DNA extraction and library preparation prior to target enrichment. Prepared libraries were used to capture 1432 Ultra-Conserved Elements (UCEs) from microhymenoptera (Chalcidoidea), which are among the tiniest insects on Earth and the most commercialized worldwide for biological control purposes. Results show no correlation between input DNA quantities (1.8-250ng, 0.4 ng with an extra whole genome amplification step) and the number of sequenced UCEs. Phylogenetic inferences highlight the potential of UCEs to solve relationships within the families of chalcid wasps, which has not been achieved so far. The protocol (library preparation + target enrichment), allows processing 96 specimens in five working days, by a single person, without requiring the use of expensive robotic molecular biology platforms, which could help to generalize the use of target enrichment for minute specimens.

The Walter Soyka species of Anaphes Haliday are reviewed and placed in context among the remaining world species. An analysis of his descriptions and identification keys is presented, and discussed in light of a broader interpretation of intraspecific variation in Anaphes species than Soyka accepted. An illustrated diagnosis of Anaphes is given and the species in Europe considered to be valid are keyed—14 species in Anaphes ( Anaphes ) and 15 species in Anaphes ( Patasson ). The 244 names of world Anaphes are tabulated in various ways and their type localities, if known, are mapped. All available valid names and their synonyms, mostly from among the 155 nominal species described by Soyka, are catalogued, with details of type material and collecting information. A total of 167 synonyms are listed, 17 of which are synonyms proposed by earlier authors and 149 of which are proposed as new synonyms. Lectotypes are designated for Mymar ferreirei Soyka and Yungaburra acutiventris Soyka. Nine nomina dubia , 2 names of fossil species that most likely do not belong to Anaphes , 3 unavailable names and 20 species transferred to other genera are listed separately; among the latter, Anagrus foersteri (Ratzeburg) is transferred to Erythmelus Enock as E. foersteri (Ratzeburg), comb. n. Host records published from 1985–2015 are tabulated; most are from the literature but a few are from unpublished records found on slide mounted Anaphes specimens in various collections, mostly in Europe. The merits of classifying the available names of nominal species into an earlier classification with subgenera Anaphes ( Anaphes ) and Anaphes ( Patasson ) instead a later classification consisting of species groups within Anaphes ( Anaphes ) and Anaphes ( Yungaburra ) are discussed; the earlier classification is preferred.

Chrysoctonoides longisetosa Huber & Triapitsyn (Hymenoptera: Mymaridae), gen. n. and sp. n., is described from Australia. It is compared with the related genus Chrysoctonus, known from Africa and the New World. Myrmecomymar Yoshimoto, syn. n., is synonymized under Chrysoctonus Mathot and its type species is transferred to Chrysoctonus as Chrysoctonus masneri (Yoshimoto), comb. n.

Bakkendorfia Mathot, syn. n. is placed in synonymy under Cleruchus Enock and its only described species transferred as Cleruchus musangae (Mathot), comb. n. Anaphes quinquearticulatus Huber & Triapitsyn, sp. n. is described; it is the only known Anaphes Haliday species with a 5-segmented funicle in females. Two genera are reported for the first time from the Afrotropical region and two species are described: Paranaphoidea (Idiocentrus) africana Huber & Triapitsyn, sp. n., and Allanagrus occidentalis Huber & Triapitsyn, sp. n.

Three New World species are transferred from Polynema Haliday to other genera of Mymaridae and redescribed based on examination of their type specimens: Polynema albicoxa Ashmead to Acmopolynema Ogloblin as Acmopolynema albicoxa (Ashmead), comb. n., Polynema porteri (Brethes) to Agalmopolynema Ogloblin as Agalmopolynema porteri (Brethes), comb. n., and Polynema giraulti Perkins, for which a lectotype is designated, to Stephanodes Enock as Stephanodes giraulti (Perkins), comb. n. Agalmopolynema shajovskoii Fidalgo, syn. n. is synonymized under Agalmopolynema porteri ; Polynema ( Dorypolynema ) gaucho Triapitsyn & Aquino, syn. n. and P. grenadensis Ashmead, syn. n., are synonymized under Polynema ( Dorypolynema ) magniceps Ashmead, for which taxonomic notes are given. Caenomymar Yoshimoto, syn. n. is synonymized under Omyomymar Schauff, and its only species Caenomymar howdeni Yoshimoto is transferred to Omyomymar as Omyomymar howdeni (Yoshimoto), comb. n. Gonatocerus chula Triapitsyn & Bernal is transferred to Cosmocomoidea Howard as Cosmocomoidea chula (Triapitsyn & Bernal), comb. n. Erythmelus mirus Girault is transferred to Cleruchoides Lin & Huber as Cleruchoides mirus (Girault), comb. n. and compared with Cleruchoides noackae Lin & Huber, a species introduced from Australia into South America as a biological control agent of Thaumastocoris peregrinus Carpintero & Dellape (Hemiptera: Thaumastocoridae), an introduced pest of Eucalyptus . Four spelling corrections are made to species names in Cosmocomoidea and Lymaenon Walker.

Two parasitoids, identified as a species each of Aprostocetus Westwood (near Aprostocetusmarylandensis (Girault)) (Hymenoptera: Eulophidae) and Platygaster Latreille (Hymenoptera: Platygastridae), were discovered in cranberry shoots (Vaccinium macrocarpon Aiton (Ericaceae)) infested with cranberry tipworm, Dasineura oxycoccana (Johnson), on a farm in Pitt Meadows, British Columbia, Canada. Parasitoids emerged from ∼18% of collected shoots in 2009, when Aprostocetus sp. was more numerous, and in 2010, when Platygaster sp. predominated. In 2009, Aprostocetus sp. was the only parasitoid species present in May and June, and predominated until late August, when Playtgaster sp. became prevalent. In 2010, Platygaster sp. was more numerous throughout June and July; numbers of Aprostocetus sp. increased in late July and early August. The parasitoids were naturally present despite applications of the insecticide diazinon.

The purpose of this application, under Articles 80.9 and 81.1 of the Code, is to designate Anaphes fuscipennis Haliday, 1833 (family mymaridae) as the type species of Anaphes Haliday, 1833. The nominal species A. punctum Shaw, 1798 is currently the type species by subsequent designation and is placed on the Official List of Specific Names in Zoology, but no type specimen of A. punctum existed until Huber (2011) showed conclusively that punctum belongs to the genus Camptoptera Foerster, 1856 and designated a neotype. It is clearly unacceptable that the type species of a genus does not belong to that genus so a request to the Commission to change the type species to the only other originally included species of Anaphes, A. fuscipennis, is presented, to maintain the current usage.

Ichneumon punctum Shaw, 1798, currently the type species of Anaphes, is shown to be a species of Camptoptera and is transferred to that genus as Camptoptera punctum Shaw, comb. n. A neotype from England, the type locality, is designated and described in order to define the species objectively and thus settle over two centuries of doubt about the species identity. Camptoptera punctum is compared to C. foersteri Girault, newly reported from the UK, and C. saintpierrei, the only other species so far reported from the UK. All three species are illustrated. Camptoptera aula, Debauche, syn. n., is synonymized under C. foersteri, whose host is likely Cis sp., possibly boleti Scopoli (Coleoptera: Ciidae).

Three species of Ooctonus (Hymenoptera: Mymaridae) are described from South Africa: O. albiclavus Huber, sp. n., O. capensis Huber, sp. n., and O. infuscatus Huber, sp. n. They represent the first records of Ooctonus from the Afrotropical Region and the first described species of Ooctonus native to the southern hemisphere. The only previously named Ooctonus from Africa (Madagascar), O. sevae Risbec, was transferred recently to Gonatocerus. A lectotype and paralectotypes are designated here for the slide-mounted and two card-mounted syntypes, respectively, of this species. One species in New Zealand, Ooctonus vulgatus Haliday, is an accidental introduction from the northern hemisphere. Online interactive keys to the South African species are available at: http://www.waspweb.org/Chalcidoidea/Mymaridae/Keys/index.htm

Illustrated identification keys are given for the superfamilies/families of insect parasitoids and the subfamilies, genera, and species of Braconidae reared from species ofChoristoneuraLederer in the Nearctic Region.Goniozus floridanus(Ashmead) (Chrysidoidea: Bethylidae) represents the third superfamily of Hymenoptera, andColpoclypeus florus(Walker) (Hymenoptera: Eulophidae) is added to the list of Chalcidoidea recorded fromChoristoneura. Fifty species of Braconidae in 18 genera and 9 subfamilies are recorded parasitizing 11Choristoneuraspecies; almost half belong to the Microgastrinae. Eight braconids (16%) were found for the first time as parasitoids ofChoristoneura. The first host record is given forOncophanes californicus(Ashmead) (Hormiinae). Known insect parasitoids ofChoristoneuraspp. in the Nearctic Region include 230 species in 106 genera, about 75% of which attack only 1 or 2Choristoneuraspecies each. An additional 36 species are considered incorrectly associated withChoristoneura, an error rate of 14%. The Banchinae (Ichneumonidae, especiallyGlyptaGravenhorst), Pimplinae (Ichneumonidae), and Microgastrinae (Braconidae) made up the greatest proportion of parasitoids. No parasitoids have yet been recorded from five NearcticChoristoneuraspecies.

Invasive alien species (IAS) cause major economic losses and threaten biodiversity worldwide. Taxonomic information is essential to initiating defence against IAS, including early detection and identification of new IAS outbreaks. We demonstrate how current IAS strategies (i.e. prevention of new invasions, early detection and rapid response to new invaders and management of established invaders) require strong taxonomic infrastructure. Examples are given from terrestrial molluscs (Gastropoda) and insects such as the Gypsy Moth, Lymantria dispar Linnaeus (Lepidoptera: Lymantriidae), disease vector flies of the families Culicidae and Calliphoridae (Diptera:), Sirex noctilio (Fabricius) (Hymenoptera: Siricidae) woodwasps and Dendroctonus bark beetles and the cabbage seedpod weevil, Ceutorhynchus obstrictus (Marsham) (Coleoptera: Curculionidae), that demonstrate the role of taxonomy in IAS response. Further, we show through the example of the Emerald Ash Borer, Agrilus planipennis Fairmaire (Coleopte...

Two new taxa, Gonatocerus (Lymaenon) bulgaricus DonevTriapitsyn (Bulgaria, and also apparently mainland Greece) and G. (Lymaenon) mediterraneus DonevTriapitsyn (Greece-Crete Island) are described, diagnosed, and illustrated. Also, a species tentatively identified as G (Lymaenon) ?beshbarmak Triapitsyn is reported from mainland Greece. If the species is indeed G. beshbarmak then this is the first record of it from Greece.

The 400+ nominal species of the worldwide genus Gonatocerus Nees are reclassified into 14 genera that are placed in Gonatocerini, which is defined by three putative autapomorphies. A key to the 13 extant genera of Gonatocerini is given, based on females. Five previously described genus-group taxa are recognized: Cosmocomoidea Howard stat. rev. (= ater group, of authors), Gahanopsis Ogloblin stat. rev. (= deficiens group, of authors), Gastrogonatocerus Ogloblin stat. n. (= membraciphagus group, of authors), Gonatocerus (= sulphuripes group, of authors), and Lymaenon Walker stat. rev. (= litoralis group, of authors). One new fossil genus, Archigonatocerus Huber gen. n., with two fossil species, A. balticus Huber sp. n., and A. longivena Huber sp. n. and one fossil species in Gonatocerus, G. janzeni Huber sp. n., are described, all from Baltic amber from the Eocene epoch. Eight new extant genera and 16 new extant species are described and their species keyed: Cosmocomopsis Huber gen. n., with C. flopsis Huber sp. n. and C. mopsis Huber sp. n.; Heptagonatocerus Huber gen. n., with H. madagascarensis Huber sp. n., H. magnificus Huber sp. n., H. parvus Huber sp. n., and H. pulchellus Huber sp. n.; Krateriske Huber gen. n., with K. ecuadorensis Huber sp. n., K. guianensis Huber sp. n., and K. peruensis Huber sp. n.; Octomicromeris Huber gen. n., with O. compacta Huber sp. n. and O. brevis Huber sp. n.; Pro-gonatocerus Huber gen. n., with P. albiclava Huber sp. n. and P. brunneiclava Huber sp. n; Tanyxiphium Huber gen. n., with T. breviovipositor Huber sp. n., T. longissimum Huber sp. n., and T. seychellense Huber sp. n. Yoshimotoana Huber gen. n. (= masneri group, of authors) with one included species and Zeyanus Huber, gen. n. (= asulcifrons group, of authors) with 9 included species. Keys to the species of seven genera: Archigonatocerus, Cosmocomopsis, Heptagonatocerus, Krateriske, Octomicromeris, Progonatocerus, and Tanyxiphium are provided. Information for each nominal species catalogued includes the original reference, kind, sex and depository of primary type, and subsequent references that include relevant previous generic combinations, if applicable. The type locality is given, based on original descriptions or, where necessary, subsequent publications that provide clarification on the collection locality. Two new synonyms are proposed: Gonatocerus similis GuptaPoorani, 2008, syn. n. under G. bialbifuniculatus Subba Rao, 1989; and Gonatocerus hispaniolus TriapitsynHuber, 2010, syn. n. under G. masneri Yoshimoto, 1990. Among the species, 245 new combinations are proposed: 82 in Cosmocomoidea, 1 in Cosmocomopsis, 4 in Gahanopsis, 8 in Gastrogonatocerus, 3 in Gonatocerus, 135 in Lymaenon, 2 in Tanyxiphium, 1 in Yoshimotoana, and 9 in Zeyanus. Revived combinations are proposed for Twelve species: 1 in Cosmocomoidea, 1 in Gahanopsis, 2 in Gonatocerus, and 8 in Lymaenon. The 410 nominal species group names are catalogued under their currently accepted genus and also listed alphabetically in an appendix. A tentative generic phylogeny is proposed.

The Mexican species of Erythmelus Enock (Hymenoptera: Mymaridae) are revised. A key to females of 13 species is provided in both English and Spanish. Two new taxa are described--E. maya Guzmán-LarraldeTriapitsyn, sp. n. and E. tigres Guzmán-LarraldeTriapitsyn, sp. n. Six species are newly recorded from Mexico--E. angustatus Ogloblin, E. cingulatus Ogloblin, E. clavatus Ogloblin, E. gracilis (Howard), E. nanus Dozier, and E. noeli (Dozier), besides new geographic records for E. miridiphagus Dozier, E. picinus (Girault), E. psallidis Gahan, and E. rex (Girault) which were previously known from the country.

Two new species of Mymaridae, Stethynium ophelimi Huber and S. breviovipositor Huber, are described from Ophelimus maskelli, a gall‐inducing pest of Eucalyptus camaldulensis accidentally introduced from Australia into the Mediterranean region and Africa. This is the first record of a species of Mymaridae reared as a larval parasitoid of a holometabolous insect. One or both of the Stethynium species are being considered for introduction into Israel for biological control of this pest. Galls containing late second or third instar larvae are suitable for successful development of Stethynium. Mean survival time in a mixed colony of adults fed with honey and water solution was 1–2 days. Stethynium perlatipenne Girault, syn. nov., is synonymized under S. flavinotae Girault.

Une étude a été effectuée dans des vergers commerciaux et non-traités du Québec et de la Nouvelle-Écosse pour déterminer l’abondance et la diversité des parasites de la mineuse marbrée, Phyllonorycter blancardella [Lepidoptera : Gracillariidae]. Au Québec, 29 espèces de parasites ont été retrouvées et elles appartenaient à 7 familles, soit Aphelinidae, Braconidae, Chalcidae, Eulophidae, Ichneumonidae, Pteromalidae et Scelionidae. Les espèces les plus fréquentes étaient : Pholetesor ornigis (67 %), Sympiesis marylandensis (11 %), S. serviceicornis (7 %), Pnigalio maculipes (1,5 %), Tetrasticus spp. (1,2 %). Toutes les autres espèces représentaient moins de 1 % des espèces trouvées. Pholetesor pedias, une espèce braconide relâchée à Frelighsburg, Québec en 1983 n’a pas été détectée en 1984 et 1985. En Nouvelle-Écosse, 19 espèces ont été trouvées et elles appartenaient à 5 familles, soit Braconidae, Chalcidae, Eulophidae, Ichneumonidae et Pteromalidae. Les espèces les plus fréquentes étaient : Pholetesor ornigis (52 %), Pnigalio maculipes (14 %), Sympiesis serviceicornis (12 %), S. marylandensis (9,5 %), Sympiesis spp. (5 %), Horismenus fraternus (1,8 %), Paraleurocerus sp. (1,3 %), Stictopisthus flaviceps (1,1 %); toutes les autres espèces représentaient moins de 1 % des espèces trouvées. Sept et cinq espèces d’hyperparasites ont été retrouvées en Nouvelle-Écosse et au Québec, respectivement. Sticopisthus bilineatus, S. flaviceps, Euderis sp., Pnigalio epilobii, P. pallipes and Paraleurocerus bicoloripes constituent des nouvelles mentions comme parasites de la mineuse marbrée pour l’Amérique du Nord., Mined leaves were collected in commercial and unsprayed (no insecticides) apple orchards of Quebec and Nova Scotia to determine the relative abundance and diversity of parasites of the spotted tentiform leafminer, Phyllonorycter blancardella [Lepidoptera: Gracillariidae]. In Quebec, 29 species of leafminer parasites were recovered, belonging to 7 families: Aphelinidae, Braconidae, Chalcidae, Eulophidae, Ichneumonidae, Pteromalidae and Scelionidae. The most prevalent species were Pholetesor ornigis (67%), Sympiesis marylandensis (11%), S. serviceicornis (7%), Pnigalio maculipes (1.5%), Tetrasticus spp. (1.2%), while all other species accounted for < 1.0%. Pholetesor pedias, a braconid released in 1983 at Frelighsburg, Quebec, was not found in the 1984 and 1985 surveys. In Nova Scotia, 19 parasite species were recovered, belonging to 5 families : Braconidae, Encyrtidae, Eulophidae, Ichneumonidae and Pteromalidae. The most prevalent species were: Pholetesor ornigis (52%), Pnigalio maculipes (14%), Sympiesis serviceicornis (12%), S. marylandensis (9.5%), Sympiesis spp. (5%), Horismenus fraternus (1.8%), Paraleurocerus sp. (1.3%), Stictopisthus flaviceps (1.1%), while all other species accounted for < 1%. Seven and five species of hyperparasites were recovered in Nova Scotia and Quebec, respectively. New records for North America for the spotted tentiform leafminer as a host are : Sticopisthus bilineatus, S. flaviceps, Euderis sp., Pnigalio epilobii, P. pallipes and Paraleurocerus bicoloripes.

Parasitism and density of obliquebanded leafroller,Choristoneura rosaceana (Harris), and thethree-lined leafroller, Pandemis limitata(Robinson) (Lepidoptera: Tortricidae), were studied in 1998–2001 in organically managed apple orchards in the southern interior of British Columbia, Canada. The density of the overwintered generation of leafrollers in spring was significantly higher than thedensity of the first generation in summer. There was a significant inverse correlation between the density of leafrollers and the percent parasitism within generation and therefore parasitoids may play a role in controlling leafroller density. Parasitism of the overwintered generation (means between 5.5 and 24.7%) was significantly lower than parasitism documented in the summer generation (means up to 67.9%). The parasitoid complex recorded as emerging from these leafrollerpopulations in 1998–1999 included 30 species, of which eight have not been previously recorded in the literature as parasitoids of either leafroller species. The most frequently occurring parasitoids included Apophuasimplicipes (Cresson) and two species of Glypta(Hymenoptera: Ichneumonidae), Macrocentrus linearis (Nees), Meteorus trachynotus Viereck, Apantelespolychrosidis Viereck, Apanteles atra (Ratzeburg) and Microgaster epagoges Gahan (Hymenoptera: Braconidae), Colpoclypeus florus (Walker) and one Sympiesisspecies (Hymenoptera: Eulophidae). All of these more common parasitoids, except Glypta sp. 1 and M. epagoges, were recorded parasitizing leafroller hosts in both leafroller generations. The number of days to adult parasitoid emergence, when field collected parasitized hosts were held at 20°C, was recorded for four of the parasitoid species. Meteorus trachynotus was found to emerge early enough in spring toparasitize the few remaining overwintered early instar leafrollers. Glypta sp. 1, A. simplicipes and one Apanteles species emerged to coincide with the first generationin the summer.

Cirrospilus flavoviridis Crawford, syn. nov., is synonymized under C. vittatus Walker. It is newly recorded as a solitary egg parasitoid from eggs of Neodiprion abietis Harris (Hymenoptera: Diprionidae) on balsam fir, Abies balsamea (L.) Mill. (Pinaceace), in New Brunswick and Newfoundland and from eggs of Neodiprion nanulus nanulus Schedl in Wisconsin.

We examined the cocoons of six species of the genera Apanteles and Dolichogenidea attacking spruce budworm, Choristoneura fumiferana Clemens, and Microlepidoptera in the same microhabitat in an effort to overcome taxonomic and ecological problems associated with the identification of these species when adults fail to emerge from their cocoons. Neither cocoon length nor width nor ratio of length to width could be used to identify the six species, owing to considerable overlap in these attributes among the species and the effects of the source of the cocoons. Using a simple technique to examine webbing characteristics of the cocoons, however, we found that each species has a unique banding pattern, determined by the manner in which the density of the webbing varies along the length of the cocoon. This pattern can be used to reliably identify each species. We describe and illustrate the webbing characteristics of each species and provide an identification key based on these characteristics.

The Mexican genera of Mymaridae (Hymenoptera: Chalcidoidea) are keyed in English and Spanish, and a catalogue of species occurring in Mexico is presented. Thirty-six genera, including 79 named species in 20 of the genera, are reported. These are mentioned in about 100 publications either as original species descriptions or as publications that specifically mention species and/or specimens from Mexico. In the catalogue, species distributions by state are given based on literature records, and collection data are compiled from about 3630 specimens examined in eight collections in Canada, Mexico and USA. Host are listed for specimens reared mainly in Mexico. A few extralimital host records are also given.

Parasitism of the leafhopper Sophonia rufofascia (Kuoh and Kuoh), a recent immigrant that has become a widespread pest in Hawaii, was examined in a 1-year survey in Hawaii Volcanoes National Park. Samples of young leaves of four plant species infested with eggs of S. rufofascia were collected at five sites ranging from 880 to 1190 m in elevation. Leafhopper eggs were parasitized principally by three species of Mymaridae (Hymenoptera): Polynema sp., Schizophragma sp. probably bicolor (Dozier), and Chaetomymar sp. Although parasitism by each species fluctuated at levels usually below 10%, all three were detected consistently across most host plants, sites, and sample periods. Total parasitism differed at a marginally significant level among host plants and sites, but not among sample periods. Total parasitism averaged 14.3% (maximum: 26.3%) on Dodonaea viscosa Jacquin, 10.6% (maximum: 17.5%) on Myrica faya Aiton, 8.7% (maximum: 29.5%) on Metrosideros polymorpha Gaudich-Beaupre, and 1.6% (maximum: 4.3%) on Vaccinium reticulatum Smith. Parasitism was generally higher at sites lower in elevation. Further monitoring is recommended to determine whether parasitism will increase to levels that can effectively suppress S. rufofascia populations. The efficacy of natural enemies already present in Hawaii is important because concern over nontarget impacts on endemic leafhoppers makes introduction of new biological control agents difficult.

Voucher specimens in a broad sense are redefined as all biological specimens having the minimum information of collection locality (ideally specified by latitude, longitude, altitude) and date that are preserved to document biological research, including taxonomic research. The importance of keeping voucher specimens, and, conversely, the consequences of not so doing, are reviewed briefly. The roles of both systematists and non-systematists in cooperating to ensure that vouchers are properly preserved is emphasized. Practical guidelines, with supporting rationale, are given for non-taxonomists on how to preserve members of the major animal phyla—arthropods, molluscs, and helminths, for taxonomic study and as vouchers.

Three new mymarid egg parasitoids of the carrot weevil,Listronotus oregonensis(LeConte) (Coleoptera: Curculionidae), are described:Anaphes coteiHuber from Nova Scotia;Anaphes listronotiHuber from Quebec; andAnaphes victusHuber from Quebec, Michigan, and Texas. A key to the species is given.Anaphes sorditatus(Girault), with which at least one of the new species was previously confused, is redescribed. Althoughlistronotiandsorditatuscannot presently be distinguished morphologically, they are biologically distinct and have different hosts. Crosses between malesordidatusand femalevictusyielded female offspring in 27% of the tests but none in the reciprocal crosses. The corresponding control crosses resulted in 90 and 30% female offspring. Mating did not occur in attempts to crosssordidatuswithlistronoti. On three occasions an unidentified species ofAnagruswas reared from field-collected carrot weevil eggs. This represents the first report of anAnagrusspecies from Curculionidae.

A new genus and species of fairyfly, Tinkerbella nana (Hymenoptera: Mymaridae) gen. n. and sp. n., is described from Costa Rica. It is compared with the related genus Kikiki Huber and Beardsley from the Hawaiian Islands, Costa Rica and Trinidad. A specimen of Kikiki huna Huber measured 158 µm long, thus holding the record for the smallest winged insect. The smallest size possible, as measured by body length, for flying insects and wingless arthropods is discussed.

The monotypic genus Mymarilla Westwood is known only from St. Helena, a remote island in the South Atlantic Ocean. The peculiar species M. wollastoni Westwood (Mymaridae) is redescribed and illustrated from non-type material. Mymarilla is compared with Cremnomymar Ogloblin spp. from the Juan Fernández Islands in the South Pacific Ocean. Stephanodes Enock is shown to be the most likely sister genus to Mymarilla. Nesopolynema Ogloblin, syn. n., Oncomymar Ogloblin, syn. n., Scolopsopteron Ogloblin, syn.n., are placed in synonymy under Cremnomymar and their species transferred as Cremnomymar caudatum (Ogloblin 1952), comb. n., C. dipteron (Ogloblin 1957), comb. n., and C. kuscheli (Ogloblin 1952), comb. n. Wing shape and wing reductions in Mymaridae are discussed in relation to biogeography, particularly with respect island faunas and to four genera, Cremnomymar, Mymarilla, Parapolynema Fidalgo, and Richteria Girault, some or all of whose species have more or less convex fore wings.

An illustrated key is given to 28 genera, representing 10 families of at least 50 chalcidoid parasitoids and hyperparasitoids recorded fromChoristoneuraspecies (Tortricidae), or their primary parasitoids, in America north of Mexico. We include species reared throughout a 12-year study of the parasitoids and hyperparasitoids associated with the spruce budworm,Choristoneura fumiferana(Clemens), in New Brunswick, Canada, as well as those listed in various catalogs. Notes are provided for all the chalcidoid species, whether or not they are recorded in the literature. Nine species doubtfully or incorrectly recorded fromChoristoneuraspecies are also discussed.Primary parasitoids belonging to the Ichneumonidae, Braconidae, and Tachinidae have been recorded from 10 of the 16 NearcticChoristoneuraspecies but chalcidoid parasitoids are recorded, usually as hyperparasitoids, from only four of the 16 species. The species of primary parasitoids ofChoristoneurachecked for records of parasitism by Chalcidoidea are tabulated by host species. Also listed are species of primary parasitoids serving as hosts for each of the chalcidoid species. We report 51 new host records of primary parasitoids and hyperparasitoids fromC. fumiferanaand its parasitoids collected in New Brunswick.A new generic combination is given:Mesopolobus tortricis(Brues) comb.nov. fromPsychophagus(proposed by Z. Boucek).

A new genus and species, Stipecarinata striata (Hymenoptera: Eulophidae: Tetrastichinae), is described from Japan. Its relationship to other tetrastichine genera is discussed.

The five species ofDimmockiaAshmead are reviewed and keyed. Members are mainly hyperparasites of Hymenoptera and Diptera parasitic on Lepidoptera, though they are also recorded as primary parasites of Lepidoptera. The NearcticD.incongruaandD.pallipesare redescribed and a lectotype is designated forD.incongrua.Dimmockia marylandicaGirault is provisionally removed fromDimmockiabut its correct placement is unknown because the unique type is lost. The PalaearcticD.brevicornisis newly recorded from North America. Additional taxonomic features are provided forD.exorientisandD.secunda. Two African species, previously placed inDimmockia, are transferred toSympiesisasS.polygoniae(Risbec) comb.nov. andS.cosmopterygi(Risbec) comb.nov. A lectotype is designated forS.polygoniae. A character analysis ofDimmockiaspecies and 21 species ofSympiesisis provided and relationships are discussed.

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. The matrix covers 22 chalcidoid families recognized herein and includes 268 genera within 78 of 83 subfamilies. Morphological data were analysed alone and in combination with molecular data from ribosomal 18S (2105 bp) and 28S D2–D5 expansion regions (1812 bp). Analyses were analysed alone and in combined datasets using implied-weights parsimony and likelihood. Proposed changes in higher classification resulting from the analyses include: (i) recognition of Eriaporidae, revised status; (ii) recognition of Cynipencyrtidae, revised status; (iii) recognition of Azotidae, revised status; (iv) inclusion of Sycophaginae in Agaonidae, revised sta- tus; (v) reclassification of Aphelinidae to include Aphelininae, Calesinae, Coccophaginae, Eretmocerinae and Eriaphytinae; (vi) inclusion of Cratominae and Panstenoninae within Pteromalinae (Pteromalidae), new synonymy; (vii) inclusion of Epichrysomalli- nae in Pteromalidae, revised status. At a higher level, Chalcidoidea was monophyletic, with Mymaridae the sister group of Rotoiti- dae plus the remaining Chalcidoidea. A eulophid lineage was recovered that included Aphelinidae, Azotidae, Eulophidae, Signiphoridae, Tetracampidae and Trichogrammatidae. Eucharitidae and Perilampidae were monophyletic if Eutrichosomatinae (Pteromalidae) was included, and Eupelmidae was monophyletic if Oodera (Pteromalidae: Cleonyminae) was included. Likelihood recovered a clade of Eupelmidae + (Tanaostigmatidae + (Cynipencyrtus + Encyrtidae). Support for other lineages and their impact on the classification of Chalcidoidea is discussed. Several life-history traits are mapped onto the new phylogeny. © The Willi Hennig Society 2013. © 2012 Her Majesty the Queen in Right of Canada Cladistics © The Willi Hennig Society 2013 Reproduced with the permission of the Minister of Agriculture and Agri-Food Canada.
