Strategies to invade and exploit hosts for survival are an essential part of the parasitic lifestyle. Species of the Polysphincta genus group (Hymenoptera: Ichneumonidae), which utilize spiders as hosts, are examples of parasitoids that present several behavioral strategies in host immobilization and egg laying. In this study, we characterized the oviposition behavior of the Darwin wasp Hymenoepimecis cameroni Townes, 1966 (Hymenoptera: Ichneumonidae) on their host spider, performed the taxonomic description of the female, and redescribed the male parasitoid. We observed eight H. cameroni females endeavoring to parasitize young Leucauge volupis (Keyserling, 1893) spiders. Each female made up to 12 successive attempts at oviposition, totaling 36 observed attacks, with only two successful attacks. The main oviposition behavior of H. cameroni individuals consists of flying close to the web and performing a direct attack on the spider, which often results in the spider escaping into the vegetation. We observed that in seven events where the spiders fled into the vegetation, the individuals of H. cameroni adopted a second strategy, which consisted of hanging from the hind legs in the web hub. This observation showed that the females of H. cameroni have the ability to modulate the oviposition strategy after a failure in the initial attack. The pattern observed for the attack of H. cameroni indicates that the ability to adjust the approach could be specific to the behavioral habits of L. volupis.

Some Ichneumonidae wasps, including the genus Acrotaphus Townes, 1960 (Ephialtini: Pimplinae), induce behavioral modification in their spider hosts. Acrotaphus is a New World parasitoid wasp genus with 26 described species. This genus belongs to the Polysphincta genus group, which are ectoparasitoids of spiders of the Araneidae. In this study, we describe a new species (Acrotaphus wagnerianae sp. n.) found in the Brazilian Amazon. In addition, we discuss for the first time the behavioral modification of spiders of the Wagneriana genus (Araneidae) by wasps of the Polysphincta genus group.

In this study, we report a new interaction of the wasp Zatypota riverai Gauld, 1991 (Ichneumonidae) parasitizing the spider Cyclosa fililineata Hingston, 1932 (Araneidae) and we describe the modified spider web. Our results show that parasitized spiders build modified webs that are clearly different from normal capture webs. This modified web presents several additional lines at the center of the web, forming a disk-like structure that was also observed in modified webs of other host orb-weaving spiders. To our knowledge, Z. riverai (this study) and Z. kauros Gauld, 1984 are the only two species of the genus Zatypota that use spiders from different families as host. However, the unexpected host C. fililineata could be an accidental host, since in the same region there are two of the typical hosts, the theridiid spiders Anelosimus baeza Agnarsson, 2006 and Theridion sp.

Los ichneumónidos (Ichneumonidae) constituyen la familia del Orden Hymenoptera con el mayor número de especies descritas a nivel mundial, más de 24,000 (Yu et al., 2012), aunque se estima que puede haber más de 100,000 especies (Gauld, 2000). Junto con Braconidae forman la superfamilia Ichneumonoidea. El número de subfamilias ha variado bastante, y se reconocen entre 30 y 40 subfamilias; en México se han registrado 1,301 especies de 373 géneros y 28 subfamilias (Ruíz, 2015).

The generic limits of Nesolinoceras Ashmead are redefined. The genus is characterized by the supraclypeal and supraantennal areas covered by distinct, uniformly spaced striae; antenna without white band; foretibia distinctly swollen, fusiform; forewing with extensive fuscous bands; areolet large, pentagonal, longer than wide, distinctly convergent; spiracle of first metasomal tergite placed at midlength; and ventral valve of ovipositor apically dilated and overlapping dorsal valve as a lobe. The type species, N. ornatipennis (Cresson) is rede-scribed, illustrated, and newly recorded from the Bahamas and the Cayman Islands. A new species, N. laluzbrillante, sp. nov., is described from the Dominican Republic. It is diagnosed mainly by having mesopleuron, propodeum, and metasoma extensively marked with blackish and whitish stripes and spots; clypeus in front view with base almost as wide as apex; central ocellus about as large as lateral ones; epicnemial carina short, reaching only 0.4 of length to subalar ridge; and areolet crossveins 2r-m and 3r-m distinctly convergent, but far from meeting on anterior apex of areolet. Previously thought to be restricted to Cuba, Nesolinoceras seems to be relatively widespread in the Caribbean Islands.

The taxonomic limits of Loxopus Townes are reviewed. The genus is characterized by the lateral margin of the clypeus projecting as subtriangular lobe; lateral lobes of fourth tarsomeres distinctly longer than mesal lobes; fore wing vein 3r-m absent; hind wing vein 2-1A absent or vestigial; and first metasomal tergite with a basolateral tooth. It occurs from Mexico to southern Brazil. Nine species are recognized, of which six are described as new: L. dodecius Santos et Aguiar, L. duckei Santos et Aguiar, L. exius Santos et Aguiar, L. ichilus Santos et Aguiar, L. tenuis Santos et Aguiar, and L. venezuelanus Santos et Aguiar. The type species, L. australis Townes, and L. multicolor Kasparyan et Ruíz-Cancino are redescribed, and a diagnosis is provided for L. unicolor Kasparyan et Ruíz- Cancino, not examined. All studied species are illustrated and distribution records are mapped. An identification key for the species of Loxopus is presented.

The Neotropical genus Melanocryptus Cameron is revised, with a new defense for the genus based on an entirely new redescription. The genus is characterized mainly by the following characters: apical half of female flagellum with a ventral stripe formed by dense, short pilosity; clypeus with a central pointy tooth; areolet large, pentagonal, about as long as wide, sides converging anteriorly; and ovipositor blade shaped, about 2.0-3.0× higher than wide. Eleven valid species are recognized: M. cyaneus (Schmiedeknecht), M. niger (Szépligeti), M. violaceipennis Cameron, M. whartoni Kasparyan et Ruíz, and seven new taxa, M. aurantius, sp. nov., M. delos Aguiar, sp. nov., M. dnopheros, sp. nov., M. hadroglyptus Aguiar, sp. nov., M. rufigladius, sp. nov., M. tesselatus Aguiar, sp. nov., and M. tupan, sp. nov. The complex morphological variation of male specimens, particularly for M. hadroglyptus, was cladistically investigated in order to objectively delimit and demonstrate the range of morphological variation of the involved species. The first host record is reported for the genus, an unidentified pyralid moth (Lepidoptera), attacked by M. whartoni. The males of M. cyaneus and M. niger are reported for the first time. Photographic illustrations and distribution maps are provided for all valid species, with several new distribution records for previously known taxa. Keys for the species are presented separately for females and males.

Abstract. 1Parasitoid wasps are species-rich and likely to be sensitive indicators of environmental change. Malaise traps are widely used for sampling certain taxa of parasitic Hymenoptera, but little is known about how they should best be used to monitor the community at an individual site.2To investigate the effects of sample duration, trap location and replication on the parasitoid assemblage, we sampled four ichneumonid subfamilies (Hymenoptera: Ichneumonidae) intensively using Malaise traps in two farm woods in the Vale of York, UK.3Species accumulation curves showed that even with 16 Malaise traps per wood, the community is incompletely sampled. Despite this, we caught up to 28% of all UK species in a single wood, implying that local parasitoid diversity may be very high.4Abundance and species richness of parasitoids differed significantly between sample periods (fortnights) and between traps, but did not differ overall between core and edge locations.5Parasitoid community composition differed between core and edge traps, but differences were much stronger in one wood than the other. One subfamily, the Poemeniinae, was found predominantly in edge locations. Catch differences became greater with increasing distance between traps.6The previous year, two traps in each of the same woods caught only half as many species, but species abundance was positively correlated between years.7Our results suggest that a small number of traps can contain useful information about the parasitoid community but is likely to seriously underestimate total species richness. To achieve extensive species coverage, sampling should continue over several weeks, with widely separated traps sampling both core and edge locations. Our focal taxa should prove excellent for monitoring the effects of environmental change on biodiversity.Parasitoid wasps are species-rich and likely to be sensitive indicators of environmental change.

Keywords Hypodinerus, Andes, Colombia, parasitic wasp, Cryptini The taxonomic limits of the Neotropical genus Dotocryptus Brèthes are reviewed. The genus is characterized mainly by the very long ovipositor, at least 2.2× as long as hind tibia; apex of ovipositor distinctly depressed, ventral valve expanded, and overlapping dorsal valve as a sheath; and mandible long with ventral tooth longer than dorsal one. A new species, Dotocryptus arcadius sp. nov., from Colombia is described and illustrated. The new species can be diagnosed mainly by the head and mesosoma with multiple whitish marks; epicnemial carina reaching 0.2-0.3 of distance to subalar ridge; legs marked with dark brown, orange, and whitish; and metasoma polished and glabrate. This is the northernmost record of the genus, previously known from Ecuador to southern Chile. An updated identification key to the species of the genus is provided, as well as diagnoses and new records for the previously known species.

The phylogeny of the ichneumonid parasitoid wasp subfamily Ateleutinae is investigated based on molecular data from five genes. A total of 36 species are included in the ingroup. Maximum likelihood analyses recovered a strongly supported monophyletic clade circumscribing the subfamily Ateleutinae. Five main clades were recovered in the sub- family, but relationships between these clades were mostly poorly supported. A new genus is identified and described: Duwalia Santos gen. nov. from Australia, which corresponds to the earliest known diverging lineage of Ateleutinae. Duwalia perula Santos sp. nov. is described and illustrated. The genus Ateleute is shown to be paraphyletic with respect to Tamaulipeca, but further studies with more intense sampling of the Neotropical fauna are needed in order to provide a comprehensive classification of the genera within this subfamily. Ateleute boitata Santos sp. nov., a mor- phologically aberrant species from South America, is described to highlight the morphological diversity in the genus. All Old World species of Ateleute are recovered in a single clade. Ateleute grossa is newly recorded as a parasitoid of Oiketicus kirbyi (Lepidoptera: Psychidae). Diagnoses and identification keys to the genera of Ateleutinae are provided.

Mesochorinae is a relatively small but widely distributed subfamily of Ichneumonidae, with most species occurring in the Neotropical Region. Currently, there are two classifications in use regarding mesochorine genera, causing numerous ta-xonomic conflicts. To resolve nomenclature conflicts, seven new replacement names and twelve new combinations are proposed for species now recognized as members of Mesochorus Gravenhorst. Herein the synonymy of Plectochorus Uchida and Stictopisthus Thomson with the genus Mesochorus s. lat. is reaffirmed, supported by the following shared character states: transverse subantennal carina partially or completely developed; supraclypeal area evenly convex, without median protrusion; clypeus not separated from supraclypeal area by depression or groove; and hind wing without vein Cu1b. An updated key to the World genera of Mesochorinae is also presented.

En la Parte II se reportan cerca de 170 especies en 22 géneros de la tribu Cryptini de México (en la Parte I fueron considerados cerca de 130 especies de 32 géneros). Por tanto, la tribu Cryptini en México incluye 54 géneros y cerca de 300 especies. Los autores esperan que la presente obra contribuirá al estudio de la biodiversidad de este gran grupo de insectos entomófagos no sólo en México sino también en Centroamérica. El contenido de este libro está acomodado en orden alfabético en las subtribus de Cryptini, los géneros en las subtribus y las especies en los géneros. El número de géneros es continuo en la tribu. En la literatura de los géneros se menciona principalmente la de América. En la literatura de las especies se anota el número de página en la que fue descrita la especie, en paréntesis el nombre genérico si la especie se describió en otro género, datos sobre tipos y localidad tipo, el museo depositario del tipo usualmente se anota en la sección de Material excepto cuando el tipo no fue estudiado.
En algunas claves se incluyeron todas las especies americanas o las de México y Centroamérica pero en la revisión sólo se incluyen las especies mexicanas. Para muchas especies se incluyó información adicional en la clave después del guión. En las antenas, cuando el número del segmento está en paréntesis indica que una parte o algunas veces todo el segmento tiene el color anotado.
El presente trabajo se basó en la Colección de Ichneumonidae del Museo de Insectos de la UAM Agronomía y Ciencias de la Universidad Autónoma de Tamaulipas (UAT, Cd. Victoria, Tamaulipas, México) y en el estudio efectuado por el primer autor de los tipos y del material comparativo de las especies neárticas, mexicanas y neotropicales de Cryptini, en las colecciones indicadas enseguida. La mayoría del material estudiado proviene de estados del este de México (desde Nuevo León hasta Yucatán); la fauna descrita previamente (Cresson, 1873, 1874 y otros) también fue de esta región, principalmente de Veracruz. Los tipos de las nuevas especies están depositados en el Museo de Insectos de la UAT, en Cd. Victoria, Tamaulipas, México.

The first comprehensive phylogenetic study of the wasp tribe Cryptini (Hymenoptera, Ichneumonidae, Cryptinae) is presented, based on 109 morphological characters and molecular data from seven loci. The dataset includes 370 species, 308 of which are from Cryptini, covering 182 of its 250 genera. Results from parsimony and likelihood analyses are generally congruent. The topology has several implications for ichneumonid higher-level classification. Previous definitions of the Ichneumoniformes clade are supported, though newly including the Microleptinae. The cryptine subtribe Ateleutina is consistently recovered outside of the Cryptini clade and should be treated as a separate subfamily, Ateleutinae stat.n. The tribe Phygadeuontini is shown to be polyphyletic: while most of the sampled taxa were recovered in a single clade, many of its members are more closely related to the Ichneumoninae, Ateleutinae or Cryptini. Pending a more detailed study, the group should be treated as a separate subfamily, Phygadeuontinae stat. rev. The former Hemigastrini are recovered as largely monophyletic but with important exceptions. Hemigaster Brullé is recovered as part of the Phygadeuontini and is transferred to that group. Echthrus Gravenhorst is consistently recovered as part of Cryptini, rendering Aptesini as the correct name for the tribe. The subfamily Cryptinae should be restricted to the tribes Aptesini and Cryptini. Within Cryptini, the results show little support for the current subtribal classification, with most subtribes recovered as polyphyletic. A number of relatively stable clades are identified and discussed, but the relationships among them are weakly supported. Most of these clades are morphologically heterogeneous and building a subtribal classification based on them would be ineffectual; they are therefore treated under the informal designation of genus groups. The results highlight the ubiquity of morphological homoplasy in Cryptini, and provide a framework from which to address further systematic and evolutionary questions on this hyperdiverse group of parasitic wasps.

The subfamily Cryptinae Kirby, 1837 is considered the largest group in the Ichneumonidae with more than 400 described genera including around 4500 species. The subfamily has a worldwide distribution and its members play a key role in the biological control as parasitoids of many important pests. The study provides a new and updated overview of the Slovakian ichneumonid fauna after 28 years. So far over 750 species of Ichneumonidae have been reported from Slovakia, including around 150 species in the subfamily Cryptinae. Our study presents a complete checklist of Cryptinae and adds 32 species to the Slovakian fauna.

By means of an international project, Argentinian and Italian researchers are carrying out joint research to study biological and ecological aspects of Tuta absoluta biological control.
This paper lists indigenous natural enemies reported for T. absoluta, as well as the current results on T. absoluta egg and larval parasitoids in both countries. Parasitoid species that
conformed to different guilds are shown to coexist in cropping conditions, and some show positive characteristics as potential biocontrol agents against T. absoluta by means of augmentative
releases. Future laboratory and field evaluations of the efficacy of biological control programs in Argentina and Italy are proposed.

terrestrial ecosystems. Subfamily Rhyssinae contains the ichneumonids with bigger size, which parasitize borers in branches and logs of diverse trees; genus Megarhyssa contains 38 species and it has been obtained in all the zoogeographical regions. The objective of this paper is to report the species of Megarhyssa collected and described from Mexico. Since 1981, ichneumónidos have been collected with entomological nets and Malaise traps in different localities of the Mexican Republic, having more than 50,000 specimens in the Insects Museum of the Faculty of Sciences and Engineering, UAT, only two of Megarhyssa macrura donated by ITESM. In the Smithsonian Institution (Washington D.C.), Kasparyan found and described a new species; in 2012 the Essig Museum of the University of California – Berkeley was visited, where other new species from the State of Chiapas was found, which was described and it is deposited in the UAT Museum mentioned above, in Cd. Victoria, Tamaulipas. Therefore, in Mexico were found Megarhyssa macrura Linnaeus 1771, M. verae Kasparyan 2002 and M. gratiosa Khalaim & Ruíz 2013. In conclusion, only three species of Megarhyssa are known in Mexico, one genus with Cosmopolitan distribution but in the American Continent its more southern distribution is the State of Chiapas.

Ichneumonidae is a family of parasitoid wasps that contributes to the regulation of insect and spider populations. Almost 1300 species are known from Mexico at the present day. About 919 samples were obtained from one Malaise trap operated from March 2010 to March 2011 in the oak forest at Rancho Santa Elena near Victoria City, Tamaulipas, Mexico. In this material, most abundant subfamilies are Pimplinae (263 specimens) and Cryptinae (247), and most diverse Cryptinae (25 genera) and Ichneumoninae (17). Most abundant genera are Pimpla Fabricius (220 specimens), Lymeon Förster (65) and Casinaria Holmgren (55), and most species rich Diapetimorpha Viereck (6 species) and Centeterus Wesmael (5). Most frequently collected species are Pimpla punicipes (Cresson) (148 specimens) and Pimpla sanguinipes (Cresson) (51). The genus Diaglyptidea Viereck (Cryptinae) is a new record from Mexico and Aphanistes Förster and Corsoncus marianoi Gauld & Bradshaw (Anomaloninae), Diradops mexicana (Cresson)...

1Insect parasitoids comprise a large fraction of terrestrial biodiversity. Because of this diversity, species-level conservation of most parasitoid species is impractical and habitat conservation must substitute. However, habitat indicators of parasitoid abundance and diversity are poorly known.2To identify such habitat indicators, parasitoid wasps in four ichneumonid subfamilies were sampled in the field herb layer of 15 woodlands in the Vale of York, UK, using Malaise traps. The catch was related to vegetation characteristics.3A total of 1543 individuals in 60 species was recorded, representing 36% of UK species in the taxa sampled. Parasitoids tended to be more abundant and species rich in woodlands with a high broadleaf content and tree species richness. This pattern was observed in the ichneumonid subfamilies Pimplinae, Poemeniinae and Diacritinae.4However, the ichneumonid subfamily Diplazontinae was found to vary in abundance and richness within rather than between woodlands and showed no association with measured habitat variables.5Reserve selection analyses indicated that coniferous woodlands, and woodlands with a low abundance and richness of parasitoids, none the less can contribute to maximizing parasitoid diversity at the landscape scale.6Synthesis and applications. At the individual woodland scale, broadleaved woodlands with high tree species richness appear best for conserving parasitoid abundance and diversity. At a landscape scale however, a variety of woodland habitat types can maximize diversity of all parasitoid taxa. We hypothesize that the degree of association between parasitoid abundance and diversity, and characteristics of the vegetation within habitats will decrease with an increase in the number of trophic links that separate them.Insect parasitoids comprise a large fraction of terrestrial biodiversity.

Ichneumonids are parasitoid wasps attacking other arthropods, mainly insects from the orders Lepidoptera, Coleoptera, Diptera and Hymenoptera; some species are external parasitoids on spiders and larvae of some others are really predators in egg shells of spiders or pseudoscorpions. Their role in natural control of holometabolous phytophagous insects is relevant in forests, grasses and shrubs in Mexico. In biological control programs, ichneumonids are outstanding, being one of the most important families in order to reduce populations of lepidopteran pests in forests and crops in temperate regions. In the Mexican Republic, 59 species have been recorded as parasitoids of diverse moths, beetles and sawflies that are primary pests or having the potential to be important pests (33 species) in forests and agricultural crops in 22 states. Only 4 species have been used in biological control programs: Bathyplectes curculionis (Thomson), Diadegma insulare (Cresson), Mallochia pyralidis Wharton and Calliephialtes grapholitae (Cresson). Many more species can be used against another pests and in different Mexican regions, choosing species well known, small sized, those attacking larvae in the first stages and emerging from the larval stage.

Ichneumonids form the family with more diversity of species in the Order Hymenoptera and one of the more diverse families in the Class Insecta. For Mexico, 1 291 species (5.3% of the world’s total) from 300 genera and 28 subfamilies are recorded; from 43 genera the species have not been identifies, for a total of 343 genera. Between 3 215 and 4 534 species are estimated for the country, considering the necessity of consistent studies in the north,central, western and southeastern regions. Fifty nine percent (760) of the species are Neotropical, 29% (371) are Neotropical and Nearctic, 10% (127) are Nearctic, and the remaining 2% (33) have other affinities. At the moment, 45% (580) of the species are considered endemics but this is because of the recent description of many new species and the necessity of more studies in Central America (except Costa Rica).

In Mexico, 28 subfamilies of Ichneumonidae have been recorded, these wasps are important in the natural control of insects and spiders in natural ecosystems. The objectives of this study were to collect Ichneumonidae in a pine - oak forest and to compare with the obtained in other six localities of the State. A Malaise trap was placed during 13 months (August 2011 - August 2012) in one locality of La Marcela, Miquihuana, Mexico, at an altitude of 2550 masl. Vegetation is dominated by Pinus pseudostrobus Lindl. and Quercus miquihuanensis Nixon & Muller. Samples were taken every two weeks. Representatives of thirteen subfamilies were obtained: Alomyinae, Banchinae, Campopleginae, Cryptinae, Ctenopelmatinae, Ichneumoninae, Mesochorinae, Metopiinae, Orthocentrinae, Oxytorinae, Pimplinae, Tersilochinae and Tryphoninae, with a total of 461 specimens. Cryptinae with 151 individuals and Campopleginae with 135 were the more abundant subfamilies while the less abundant were Ctenopelmatinae (3 individuals), Tersilochinae (3), Alomyinae (2) and Oxytorinae (1). Altitude, vegetation type and the collection time influenced directly the number of specimens collected, diversity and distribution in the State. The genera Compsocryptus, Cryptus, Latosculum and Messatoporus were captured in the Marcela, and at lower altitudes in the different types of vegetation, except for a site with huisachal (294 masl); the genus Compsocryptus was present in the majority of the localities. The accumulation curve and the rarefaction curve were calculated for the material from La Marcela.

Xanthopimpla Saussure, 1892 is one of the largest and best studied genera of the family Ichneumonidae. It is most species
rich in the Oriental and Afrotropical regions with only a few species occurring in Central and South America. The present
study reviews the Neotropical species of the genus including descriptions of four new species from Amazonia and Northeast
South America. We define a new species group: the amazonica species-group, to accommodate the following five
species: X. amazonica Gómez, Sääksjärvi & Veijalainen, X. guianensis Gómez & Sääksjärvi sp. n., X. jussilai Veijalainen,
Sääksjärvi & Broad, X. pucallpensis Gómez & Sääksjärvi sp. n. and X. vidali Gómez sp. n. The aurita species-group, which had hitherto been regarded as the only species-group in the Neotropical region, is currently represented by five species:
X. allpahuaya Gómez & Sääksjärvi sp. n., X. aurita Krieger, X. craspedoptera Krieger, X. rhabdomera Townes and X. spiloptera Krieger. The Andean species X. peruana Krieger is established as an unplaced species outside of the amazonica
and aurita species-groups. A key to Neotropical species-groups and species of Xanthopimpla is provided. Xanthopimpla aurita is recorded for the first time from Ecuador and Colombia and its extensive distribution is discussed. Xanthopimpla amazonica, X. craspedoptera and X. jussilai are recorded for the first time from Brazil; X. amazonica is recorded for the first time from French Guiana; X. spiloptera is recorded for the first time from French Guiana and Peru, and X. rhabdomera is recorded for the first time from Peru.

This study was conducted to collect and identify ichneumonid parasitoids of tephritid fruit flies (Diptera: Tephritidae) feeding on the plants of the family Asteraceae in the northwest of Iran during 2013-2015. Five species of ichneumon wasps on five species of fruit flies were reared. They were as follows: Cremastus lineatus on Urophora terebrans; Diadegma maculatum on Hypenidium robrowskii; Scambus brevicornis on Sphenella marginata, Scambus rufator on Terellia gynacochroma and Urophora sp. and Tranosema sp. on Tephritis sp. dioscurea group. Of them, Cremastus lineatus, S. rufator and Tranosema sp. are new records for ichneumonid fauna of Iran. All host-parasitoid-plant associations were newly established to the science. General distribution of these parasitoids and their biological associations were discussed.

The knowledge of invertebrate diversity in Uruguay is much less as compared to bird and tetrapod fauna, but some important advances have been made within some groups of insects. The Ichneumonidae constitute one of the largest families in the animal kingdom. This family is important because their larvae can be either endo-or ectoparasitoids of larvae or pupae of holometabolous insects as well as Chelicerata. In this study ichneumonid wasps were collected from three environments near the city of Castillos, Rocha Department, Uruguay between December 2014 and December 2016. A total of 5740 Ichneumonidae specimens were collected, representing 19 subfamilies, of which 3685 specimens (64.2%) correspond to three subfamilies: Campopleginae (1533 specimens/26.7%), Ichneumoninae (1303/22.7%) and Cryptinae (849/14.8%) ; all others subfamilies together represented less than 7.0% of the total specimens. In addition, 32 genera were registered for the first time in Uruguay.
