In this study, the genus Glypta is reported for the first time from South Korea. Twelve species are recognized, one of which is described as new: Glypta clypeorostrata sp. nov. We diagnose 11 newly recorded species (G. biauriculata, G. breviterebra, G. densepunctata, G. extincta, G. fronticornis, G. incisa, G. media, G. nigrina, G. talitzkii, G. tamanukii, and G. touyaensis) and provide a key along with digital images of 12 South Korean species.

Glypta Gravenhorst is the largest genus of tribe Glyptini In this paper, we report the genus Glypta for the first time comprising 505 species with a worldwide distribution (Wata­ from South Korea with a new species (Glypta clypeorostrata nabe, 2017). As a member of the tribe Glyptini Cushman sp. nov.) and 11 newly recorded species (G. biauriculata, G. and Rohwer, Glypta can be distinguished as follows: fore breviterebra, G. densepunctata, G. extincta, G. fronticornis, G. wing without areolet, fore tibial spur not reaching middle of incisa, G. media, G. nigrina, G. talitzkii, G. tamanukii, and G. fore basitarsus, prepectal carina present, and upper hind part touyaensis). We also provide diagnoses and a key along with of head not strongly impressed and without teeth (Townes, digital images. 1970).

E-mail: [email protected] Abstract Japanese species of the genus Apophua Morley, 1913, are revised. Eleven species are found from Japan and two of them, A. elegans sp. nov. and A. yamato sp. nov., are newly described. Distribution data and an updated key to Japanese species are provided. Key words: Far East Asia, Glyptini, new species, parasitoid, taxonomy Introduction The genus Apophua Morley, 1913, is a medium-sized taxon of ichneumonid wasps of the tribe Glyptini, subfamily Banchinae, which contains 36 described species from the Afrotropical (13 spp.), Eastern Palaearctic (10), Oriental (10), Western Palaearctic (5), Nearctic (2), and Australasian (2) regions (Yu et al., 2012). The species in this genus are known as koinobiont endoparasitoids of lepidopteran larvae, particularly of leaf rollers (e.g. Tortricidae), and include some important natural enemies of forest pests (Kamijo, 1973; Momoi et al., 1975). We have studied the Japanese species of Apophua as part of a review of the Japanese Glyptini and have recognized 11 species.

  • Identification Key to the Subfamilies of Ichneumonidae (Hymenoptera)
    Identification key to the subfamilies of Ichneumonidae (Hymenoptera) Gavin Broad Dept. of Entomology, The Natural History Museum, Cromwell Road, London SW7 5BD, UK Notes on the key, February 2011 This key to ichneumonid subfamilies should be regarded as a test version and feedback will be much appreciated (emails to [email protected]). Many of the illustrations are provisional and more characters need to be illustrated, which is a work in progress. Many of the scanning electron micrographs were taken by Sondra Ward for Ian Gauld’s series of volumes on the Ichneumonidae of Costa Rica. Many of the line drawings are by Mike Fitton. I am grateful to Pelle Magnusson for the photographs of Brachycyrtus ornatus and for his suggestion as to where to include this subfamily in the key. Other illustrations are my own work. Morphological terminology mostly follows Fitton et al. (1988). A comprehensively illustrated list of morphological terms employed here is in development. In lateral views, the anterior (head) end of the wasp is to the left and in dorsal or ventral images, the anterior (head) end is uppermost. There are a few exceptions (indicated in figure legends) and these will rectified soon. Identifying ichneumonids Identifying ichneumonids can be a daunting process, with about 2,400 species in Britain and Ireland. These are currently classified into 32 subfamilies (there are a few more extralimitally). Rather few of these subfamilies are reconisable on the basis of simple morphological character states, rather, they tend to be reconisable on combinations of characters that occur convergently and in different permutations across various groups of ichneumonids.

Previous studies have found the parasitoid wasp family Ichneumonidae (Hymenoptera) to have an exceptional latitudinal species richness gradient that peaks at mid-latitudes instead of the tropics; however, insufficient tropical sampling and species description may have biased the conclusions. It has been unclear which subfamilies might be species rich in tropical lowland rain forests. 2. This study reports the subfamily abundance composition of a large ichneumo- nid data set (>30 000 individuals in 20 subfamilies) collected by Malaise traps and insecticidal canopy fogging in Amazonian Ecuador and Peru and suggests which subfamilies would be important for future study. 3. Relative abundance data from one Peruvian site are compared to similar low- land samples from Costa Rica and Georgia (USA). 4. Contrary to a common assumption, a number of ichneumonid subfamilies are very abundant and presumably species rich in western Amazonia. Cryptinae and Or- thocentrinae are noticeably the two most abundant subfamilies, and a number of koinobiont lepidopteran parasitoids, which are generally thought to be scarce in the tropics, are also surprisingly abundant (e.g.

    ISSN 0065-1737 Acta Zoológica Mexicana (n.s.) 25(3): 655-657 (2009) Nota científica (Short communication) REGISTRO PARA MÉXICO DE LISSONOTA FASCIPENNIS TOWNES (HYMENOPTERA: ICHNEUMONIDAE) COMO PARASITOIDE DEL GUSANO ROJO DEL MAGUEY Zetina, D. A. H., C. Llanderal-Cázares, E. Ruíz Cancino & A. I. Khalaim. 2009. Record for Mexico of Lissonota fascipennis Townes (Hymenoptera: Ichneumonidae) as parasitoid of the agave red worm. Acta Zoológica Mexicana (n. s.), 25(3): 655-657. ABSTRACT. The agave red worm, Comadia redtenbacheri Hamm. (Lepidoptera: Cossidae), is an edible insect in several states of Mexico. Its larval development is affected by the parasitic species Lissonota fascipennis Townes, which constitutes a new host record for Mexico. Furthermore, this ichneumonid species is a new record for the country. El gusano rojo del maguey, Comadia redtenbacheri Hammerschmidt, es un insecto apreciado por su contenido alimenticio (Conconi et al. 1982) y llega a representar una fuente de ingresos económicos (Ramos-Elorduy & Pino 2001). Sin embargo, existen enemigos naturales de la larva de Comadia redtenbacheri, principalmente de los órdenes Hymenoptera y Diptera, así como varios agentes microbianos. El orden Hymenoptera contiene a la familia Ichneumonidae, la cual presenta una amplia diversidad de especies, muchas de las cuales se han utilizado para el control de diversas plagas de lepidópteros trozadores, minadores, defoliadores y barrenadores (Goulet & Huber 1993). La subfamilia Banchinae pertenece a esta familia y presenta miembros endoparasitoides de larvas de lepidópteros (Ruíz-Cancino et al. 2002). En la localidad de San Juan Tianguistongo, municipio de Hueypoxtla, México (20º 00’ 45’’ norte y 99º 02’ 34’’ oeste, 2494 m), se colectaron el 27 de agosto de 2007, 31 plantas de maguey con síntomas de presencia del gusano rojo, mismas que se trasladaron en bolsas de plástico al Colegio de Postgraduados, campus Montecillo, México, para su extracción, obteniendo un total de 600 larvas de las plantas.

  • Ichneumonidae (Hymenoptera) As Biological Control Agents of Pests
    Ichneumonidae (Hymenoptera) As Biological Control Agents Of Pests A Bibliography Hassan Ghahari Department of Entomology, Islamic Azad University, Science & Research Campus, P. O. Box 14515/775, Tehran – Iran; [email protected] Preface The Ichneumonidae is one of the most species rich families of all organisms with an estimated 60000 species in the world (Townes, 1969). Even so, many authorities regard this figure as an underestimate! (Gauld, 1991). An estimated 12100 species of Ichneumonidae occur in the Afrotropical region (Africa south of the Sahara and including Madagascar) (Townes & Townes, 1973), of which only 1927 have been described (Yu, 1998). This means that roughly 16% of the afrotropical ichneumonids are known to science! These species comprise 338 genera. The family Ichneumonidae is currently split into 37 subfamilies (including, Acaenitinae; Adelognathinae; Agriotypinae; Alomyinae; Anomaloninae; Banchinae; Brachycyrtinae; Campopleginae; Collyrinae; Cremastinae; Cryptinae; Ctenopelmatinae; 1 Diplazontinae; Eucerotinae; Ichneumoninae; Labeninae; Lycorininae; Mesochorinae; Metopiinae; Microleptinae; Neorhacodinae; Ophioninae; Orthopelmatinae; Orthocentrinae; Oxytorinae; Paxylomatinae; Phrudinae; Phygadeuontinae; Pimplinae; Rhyssinae; Stilbopinae; Tersilochinae; Tryphoninae; Xoridinae) (Yu, 1998). The Ichneumonidae, along with other groups of parasitic Hymenoptera, are supposedly no more species rich in the tropics than in the Northern Hemisphere temperate regions (Owen & Owen, 1974; Janzen, 1981; Janzen & Pond, 1975), although

Thousands of species from the campoplegine and banchine wasp subfamilies rely, for their survival, on their association with these viruses, hijacked from a yet undetermined viral taxon. Here, we give an update of recent findings on the nature of the viral genes retained from the progenitor viruses and how they are organized in the wasp genome. Keywords: parasitoid wasp; ichnovirus; virus-like particles; endogenous viruses; mutualistic viruses; genomic architecture 1. Introduction The ichneumonid wasps (Hymenoptera: Ichneumonidae) form a very large and diverse group of insects [1] that share a life cycle involving parasitism. Around 25,000 ichneumonid species have been described to date [2], but their actual numbers are estimated to be about four times this high [3]. Many ichneumonid species are endoparasitoids: the females lay their eggs inside another insect, usually an insect larva, where their progeny develops (Figure1). Amazingly, in many cases the parasitized insect continues its development, and usually only dies once the parasitoid has completed its larval development.

Mandible weakly tapering, northern Mexico, is morphologicaly intermediate with upper tooth longer than lower tooth. Malar between the genera Alloplasta Förster, 1869 and space about 0.6 times the basal mandibular width. Cryptopimpla Taschenberg, 1863, and probably Face, frons and vertex distinctly and very densely belongs to a new genus. Alloplasta possesses punctate, matt.
